SICHERHEIT / SAFETY

Installation

Vor der Installation des Gerätes müssen die hier aufgeführten und auch die weiter in dieser Anleitung mit bezeichneten Hinweise gelesen und während der Installation und des Betriebes beachtet werden. Untersuchen Sie das Gerät und sein Zubehör auf allfällige Transportschäden. Ein Gerät, das mechanische Beschädigung aufweist oder in welches Flüssigkeit oder Gegenstände eingedrungen sind, darf nicht ans Netz angeschlossen oder muss sofort durch Ziehen des Netzsteckers vom Netz getrennt werden. Das Öffnen und Instandsetzen des Gerätes darf nur von Fachpersonal unter Einhaltung der geltenden Vorschriften durchgeführt werden.

Falls dem Gerät kein konfektioniertes Netzkabel beiliegt, muss dieses durch eine Fachperson unter Verwendung der mitgelieferten Kabel-Gerätedose IEC320/C13 oder IEC320/C19 und unter Berücksichtigung der einschlägigen, im geweiligen Lande geltenden Bestimmungen angefertigt werden; siehe unten. Vor Anschluss des Netzkabels an die Netzsteckdose muss überprüft werden, ob die Stromversorgungs- und Anschlusswerte des Gerätes (Netzspannung, Netzfrequenz) innerhalb der erlaubten Toleranzen liegen. Die im Gerät eingesetzten Sicherungen müssen den am Gerät angebrachten Angaben entsprechen. Ein Gerät mit einem dreipoligen Gerätestecker (Gerät der Schutzklasse I) muss an eine dreipolige Netzsteckdose angeschlossen und somit das Gerätegehäuse mit dem Schutzleiter der Netzinstallation verbunden werden (Für Dänemark gelten Starkstrombestimmungen, Abschnitt 107).

Installation

Before you install the equipment, please read and adhere to the following recommendations and all sections of these instructions marked with .

Check the equipment for any transport damage.

A unit that is mechanically damaged or which has been penetrated by liquids or foreign objects must not be connected to the AC power outlet or must be immediately disconnected by unplugging the power cable. Repairs must only be performed by trained personnel in accordance with the applicable regulations.

Should the equipment be delivered without a matching mains cable, the latter has to be prepared by a trained person using the attached female plug (IEC320/C13 or IEC320/C19) with respect to the applicable regulations in your country - see diagram below.

Before connecting the equipment to the AC power outlet, check that the local line voltage matches the equipment rating (voltage, frequency) within the admissible tolerance. The equipment fuses must be rated in accordance with the specifications on the equipment.

Equipment supplied with a 3-pole appliance inlet (equipment conforming to protection class I) must be connected to a 3-pole AC power outlet so that the equipment cabinet is connected to the protective earth conductor of the AC supply (for Denmark the Heavy Current Regulations, Section 107, are applicable).

SICHERHEIT / SAFETY

Zugentlastung für den Netzanschluss

Zum Verankern von Steckverbindungen ohne mechanische Verriegelung (z.B. IEC-Kaltgerätedosen) empfehlen wir die folgende Anordnung:

Mains connector strain relief

For anchoring connectors without a mechanical lock (e.g. IEC mains connectors), we recommend the following arrangement:

Vorgehen: Der mitgelieferte Kabelhalter ist selbstklebend. Bitte beachten Sie bei der Montage die folgenden Regeln:

1. Der Untergrund muss sauber, trocken und frei von

Fett, Öl und anderen Verunreinigungen sein. Temperaturbereich für optimale Verklebung: 20...40° C.

2. Entfernen Sie die Schutzfolie auf der Rückseite des

Kabelhalters und bringen sie ihn mit kräftigem Druck an der gewünschten Stelle an. Lassen sie ihn unbelastet so lange wie möglich ruhen – die maximale Klebekraft ist erst nach rund 24 Stunden erreicht.

3. Die Stabilität des Kabelhalters wird erhöht, wenn

Sie ihn zusätzlich verschrauben. Zu diesem Zweck liegen ihm eine selbstschneidende Schraube sowie eine M4-Schraube mit Mutter bei.

4. Legen Sie das Kabel gemäss Figur in den Halter ein

und pressen Sie die Klemme kräftig auf, bis das Kabel fixiert ist.

Procedure: The cable clamp shipped with your unit is auto-adhesive. If mounting, please follow the rules below:

1. The surface to be adhered to must be clean, dry, and

free from grease, oil or other contaminants. Best application temperature range is 20...40° C.

2. Remove the plastic protective backing from the rear

side of the clamp and apply it firmly to the surface at the desired position. Allow as much time as possible for curing. The bond continues to develop for as long as 24 hours.

3. For improved stability, the clamp can be fixed with

a screw. For this purpose, a self-tapping screw and an M4 bolt and nut are included.

4. Place the cable into the clamp as shown in the illus-

tration above and firmly press down the internal top cover until the cable is fixed.

UMGEBUNGSBEDINGUNGEN / AMBIENT CONDITIONS

Lufttemperatur und Feuchtigkeit

Allgemein

Die Betriebstauglichkeit des Gerätes oder Systems ist unter folgenden Umgebungsbedingungen gewährleistet:

EN 60721-3-3, Set IE32, Wert 3K3.

Diese Norm umfasst einen umfassenden Katalog von Parametern; die wichtigsten davon sind: Umgebungstemperatur +5...+40 °C; rel. Luftfeuchtigkeit 5...85% – d.h. weder Kondensation noch Eisbildung; abs. Luftfeuchtigkeit 1...25 g/m³; Temperatur-Änderungsrate < 0,5 °C/min. In den folgenden Abschnitten wird darauf näher eingegangen. Unter den genannten Bedingungen startet und arbeitet das Gerät oder System problemlos. Ausserhalb dieser Spezifikationen möglicherweise auftretende Probleme sind in den folgenden Abschnitten beschrieben.

Umgebungstemperatur

Geräte und Systeme von Studer sind allgemein für einen Umgebungstemperaturbereich (d.h. Temperatur der eintretenden Kühlluft) von +5...+40 °C ausgelegt. Bei Installation in einem Schrank muss der vorgesehene Luftdurchsatz und dadurch die Konvektionskühlung gewährleistet sein. Folgende Tatsachen sind dabei zu berücksichtigen:

1. Die zulässige Umgebungstemperatur für den Betrieb der Halbleiter-Bauelemente beträgt 0 °C bis +70 °C (commercial temperature range for operation).

2. Der Luftdurchsatz der Anlage muss gewährleisten, dass die austretende Kühlluft ständig kühler ist als 70 °C.

3. Die mittlere Erwärmung der Kühlluft soll 20 K betragen, die maximale Erwärmung an den heissen Komponenten darf somit um weitere 10 K höher liegen.

4. Zum Abführen einer Verlustleistung von 1 kW bei dieser zulässigen mittleren Erwärmung ist eine Luftmenge von 2,65 m³/min notwendig. Beispiel: Für ein Rack mit einer Leistungsaufnahme P = 800 W ist eine Kühlluftmenge von 0,8 * 2,65 m³/min nötig, entsprechend 2,12 m³/min.

5. Soll die Kühlfunktion der Anlage (z.B. auch bei LüfterAusfall oder Bestrahlung durch Spotlampen) überwacht werden, so ist die Temperatur der Abluft unmittelbar oberhalb der Einschübe an mehreren Stellen im Rack zu messen; die Ansprechtemperatur der Sensoren soll 65 bis 70 °C betragen.

Air temperature and humidity

General

Normal operation of the unit or system is warranted under the following ambient conditions defined by:

EN 60721-3-3, set IE32, value 3K3.

This standard consists of an extensive catalogue of parameters, the most important of which are: ambient temperature +5... +40° C, relative humidity 5...85% – i.e. no formation of condensation or ice; absolute humidity 1...25 g/m³; rate of temperature change < 0,5 °C/min. These parameters are dealt with in the following paragraphs. Under these conditions the unit or system starts and works without any problem. Beyond these specifications, possible problems are described in the following sections.

Ambient temperature

Units and systems by Studer are generally designed for an ambient temperature range (i.e. temperature of the incoming air) of +5...+40 °C. When rack mounting the units, the intended air flow and herewith adequate cooling must be provided. The following facts must be considered:

1. The admissible ambient temperature range for operation of the semiconductor components is 0 °C to +70 °C (commercial temperature range for operation).

2. The air flow through the installation must provide that the outgoing air is always cooler than 70 °C.

3. Average heat increase of the cooling air shall be 20 K, allowing for an additional maximum 10 K increase at the hot components.

4. In order to dissipate 1 kW with this admissible average heat increase, an air flow of 2,65 m³/min is required.

Example: A rack dissipating P = 800 W requires an air flow of 0,8 * 2,65 m³/min which corresponds to 2,12 m³/min.

5. If the cooling function of the installation must be monitored (e.g. for fan failure or illumination with spot lamps), the outgoing air temperature must be measured directly above the modules at several places within the rack. The trigger temperature of the sensors should be 65 to 70 °C.

Reif und Tau

Das unversiegelte System (Steckerpartien, Halbleiteranschlüsse) verträgt zwar leichte Eisbildung (Reif). Mit blossem Auge sichtbare Betauung führt jedoch bereits zu Funktionsstörungen. In der Praxis kann mit einem zuverlässigen Betrieb der Geräte bereits im Temperaturbereich ab –15 °C gerechnet werden, wenn für die Inbetriebnahme des kalten Systems die folgende allgemeine Regel beachtet wird: Wird die Luft im System abgekühlt, so steigt ihre relative Feuchtigkeit an. Erreicht diese 100%, kommt es zu Niederschlag, meist in der Grenzschicht zwischen der Luft und einer kühleren Oberfläche, und somit zur Bildung von Eis oder Tau an empfindlichen Systemstellen (Kontakte, IC-Anschlüsse etc.). Ein störungsfreier Betrieb mit interner Betauung, unabhängig von der Temperatur, ist nicht gewährleistet.

Frost and dew

The unsealed system parts (connector areas and semiconductor pins) allow for a minute formation of ice or frost. However, formation of dew visible with the naked eye will already lead to malfunctions. In practice, reliable operation can be expected in a temperature range above –15 °C, if the following general rule is considered for putting the cold system into operation:

If the air within the system is cooled down, the relative humidity rises. If it reaches 100%, condensation will arise, usually in the boundary layer between the air and a cooler surface, together with formation of ice or dew at sensitive areas of the system (contacts, IC pins, etc.). Once internal condensation occurs, troublefree operation cannot be guaranteed, independent of temperature.

UMGEBUNGSBEDINGUNGEN / AMBIENT CONDITIONS

Vor der Inbetriebnahme muss das System auf allfällige interne Betauung oder Eisbildung überprüft werden. Nur bei sehr leichter Eisbildung kann mit direkter Verdunstung (Sublimation) gerechnet werden; andernfalls muss das System im abgeschalteten Zustand gewärmt und getrocknet werden. Das System ohne feststellbare interne Eisbildung oder Betauung soll möglichst homogen (und somit langsam) mit eigener Wärmeleistung aufgewärmt werden; die Lufttemperatur der Umgebung soll ständig etwas tiefer als diejenige der Systemabluft sein. Ist es unumgänglich, das abgekühlte System sofort in warmer Umgebungsluft zu betreiben, so muss diese entfeuchtet sein. Die absolute Luftfeuchtigkeit muss dabei so tief sein, dass die relative Feuchtigkeit, bezogen auf die kälteste Oberfläche im System, immer unterhalb 100% bleibt. Es ist dafür zu sorgen, dass beim Abschalten des Systems die eingeschlossene Luft möglichst trocken ist (d.h. vor dem Abschalten im Winter den Raum mit kalter, trockener Luft belüften und feuchte Gegenstände, z.B. Kleider, entfernen). Die Zusammenhänge sind im folgenden Klimatogramm ersichtlich. Zum kontrollierten Verfahren gehören Thermometer und Hygrometer sowie ein Thermometer innerhalb des Systems. Beispiel 1: Ein Ü-Wagen mit einer Innentemperatur von 20 °C und 40% relativer Luftfeuchtigkeit wird am Abend abgeschaltet. Sinkt die Temperatur unter +5 °C, bildet sich Tau oder Eis. Beispiel 2: Ein Ü-Wagen wird morgens mit 20 °C warmer Luft von 40% relativer Luftfeuchtigkeit aufgewärmt. Auf Teilen, die kälter als +5 °C sind, bildet sich Tau oder Eis.

Before putting into operation, the system must be checked for internal formation of condensation or ice. Only with a minute formation of ice, direct evaporation (sublimation) may be expected; otherwise the system must be heated and dried while switched off. A system without visible internal formation of ice or condensation should be heated up with its own heat dissipation, as homogeneously (and subsequently as slow) as possible; the ambient temperature should then always be lower than the outgoing air. If it is absolutely necessary to operate the system immediately within warm ambient air, this air must be dehydrated. In such a case, the absolute humidity must be so low that the relative humidity, related to the coldest system surface, always remains below 100%. Ensu re that t he enclosed air is as dr y as p ossibl e when powering off (i.e. before switching off in winter, aerate the room with cold, dry air, and remove humid objects as clothes from the room). These relationships are visible from the following climatogram. For a controlled procedure, thermometer and hygrometer as well as a thermometer within the system will be required. Example 1: An OB-van having an internal temperature of 20 °C and rel. humidity of 40% is switched off in the evening. If temperature falls below +5 °C, dew or ice will be forming. Example 2: An OB-van is heated up in the morning with air of 20 °C and a rel. humidity of 40%. On all parts being cooler than +5 °C, dew or ice will be forming.

WARTUNG / MAINTENANCE

Wartung und Reparatur

Durch Entfernen von Gehäuseteilen, Abschirmungen etc. werden stromführende Teile freigelegt. Deshalb müssen u.a. die folgenden Grundsätze beachtet werden: Eingriffe in das Gerät dürfen nur von Fachpersonal unter Einhaltung der geltenden Vorschriften vorgenommen werden. Vor Entfernen von Gehäuseteilen muss das Gerät ausgeschaltet und vom Netz getrennt werden. Bei geöffnetem, vom Netz getrenntem Gerät dürfen Teile mit gefährlichen Ladungen (z. B. Kondensatoren, Bildröhren) erst nach kontrollierter Entladung, heiße Bauteile (Leistungshalbleiter, Kühlkörper etc.) erst nach deren Abkühlen berührt werden.

Bei Wartungsarbeiten am geöffneten, unter Netzspannung stehenden Gerät dürfen blanke Schaltungsteile und metallene Halbleitergehäuse weder direkt noch mit nichtisoliertem Werkzeug berührt werden. Zusätzliche Gefahren bestehen bei unsachgemässer Handhabung besonderer Komponenten:

• Explosionsgefahr bei Lithiumzellen, Elektrolyt-Kon-

densatoren und Leistungshalbleitern

• Implosionsgefahr bei evakuierten Anzeigeeinheiten

• Strahlungsgefahr bei Lasereinheiten (nichtioni-

sierend), Bildröhren (ionisierend)

• Verätzungsgefahr bei Anzeigeeinheiten (LCD) und

Komponenten mit flüssigem Elektrolyt.

Solche Komponenten dürfen nur von ausgebildetem Fachpersonal mit den vorgeschriebenen Schutzmitteln (u.a. Schutzbrille, Handschuhe) gehandhabt werden.

Maintenance and Repair

The removal of housing parts, shields, etc. exposes energized parts. For this reason the following precautions should be observed: Maintenance should only be performed by trained personnel in accordance with the applicable regulations. The equipment should be switched off and disconnected from the AC power outlet before any housing parts are removed. Even if the equipment is disconnected from the power, parts with hazardous charges (e.g. capacitors, picture tubes) must not be touched until they have been properly discharged. Touch hot components (power semiconductors, heat sinks, etc.) only when cooled off.

If maintenance is performed on a unit that is opened and switched on, no uninsulated circuit components and metallic semiconductor housings must be touched neither with your bare hands nor with uninsulated tools. Certain components pose additional hazards:

• Explosion hazard from lithium batteries, electrolytic

capacitors and power semiconductors

• Implosion hazard from evacuated display units

• Radiation hazard from laser units (non-ionizing),

picture tubes (ionizing)

• Caustic effect of display units (LCD) and such com-

ponents containig liquid electrolyte.

Such components should only be handled by trained personnel who are properly protected (e.g. safety goggles, gloves).

WARTUNG / MAINTENANCE

Elektrostatische Entladung (ESD) bei Wartung und Reparatur

ATTENTION:

ACHTUNG:

Viele ICs und andere Halbleiter sind empfindlich gegen elektrostatische Entladung (ESD). Unfachgerechte Behandlung von Baugruppen mit solchen Komponenten bei Wartung und Reparatur kann deren Lebensdauer drastisch vermindern. Bei der Handhabung der ESD-empfindlichen Komponenten sind u.a. folgende Regeln zu beachten:

Electrostatic Discharge (ESD) during Maintenance and Repair

Observe precautions for handling devices sensitive to electrostatic discharge!

Respecter les précautions d’usage concernant la manipulation de composants sensibles à l’électricité statique!

Vorsichtsmassnahmen bei Handhabung elektrostatisch entladungsgefährdeter Bauelemente beachten!

Many ICs and semiconductors are sensitive to electrostatic discharge (ESD). The life of components containing such elements can be drastically reduced by improper handling during maintenance and repair work.

Please observe the following rules when handling ESD sensitive components:

• ESD-empfindliche Komponenten dürfen ausschliesslich in dafür bestimmten und bezeichneten Verpackungen gelagert und transportiert werden.

• Unverpackte, ESD-empfindliche Komponenten dürfen nur in dafür eingerichteten Schutzzonen (EPA, z.B. Gebiet für Feldservice, Reparatur- oder Serviceplatz) gehandhabt und nur von Personen berührt werden, die durch ein Handgelenkband mit Seriewiderstand mit dem Massepotential des Reparaturoder Serviceplatzes verbunden sind. Das gewartete Gerät wie auch Werkzeug, Hilfsmittel, EPAtaugliche (elektrisch halbleitende) Arbeits-, Ablageund Bodenmatten müssen ebenfalls mit diesem Potential verbunden sein.

• Die Anschlüsse der ESD-empfindlichen Komponenten dürfen unkontrolliert weder mit elektrostatisch aufladbaren (Gefahr von Spannungsdurchschlag), noch mit metallischen Oberflächen (Schockentladungsgefahr) in Berührung kommen.

• Um undefinierte transiente Beanspruchung der Komponenten und deren eventuelle Beschädigung durch unerlaubte Spannung oder Ausgleichsströme zu vermeiden, dürfen elektrische Verbindungen nur am abgeschalteten Gerät und nach dem Abbau allfälliger Kondensatorladungen hergestellt oder getrennt werden.

• ESD sensitive components should only be stored and transported in the packing material specifically provided for this purpose.

• Unpacked ESD sensitive components should only be handled in ESD protected areas (EPA, e.g. area for field service, repair or service bench) and only be touched by persons who wear a wristlet that is connected to the ground potential of the repair or service bench by a series resistor. The equipment to be repaired or serviced and all tools, aids, as well as electrically semiconducting work, storage and floor mats should also be connected to this ground potential.

• The terminals of ESD sensitive components must not come in uncontrolled contact with electrostatically chargeable (voltage puncture) or metallic surfaces (discharge shock hazard).

• To prevent undefined transient stress of the components and possible damage due to inadmissible voltages or compensation currents, electrical connections should only be established or separated when the equipment is switched off and after any capacitor charges have decayed.

WARTUNG / MAINTENANCE

SMD-Bauelemente

Der Austausch von SMD-Bauelementen ist ausschliesslich geübten Fachleuten vorbehalten. Für verwüstete Platinen können keine Ersatzansprüche geltend gemacht werden. Beispiele für korrekte und falsche SMDLötverbindungen in der Abbildung weiter unten.

Bei Studer werden keine handelsüblichen SMD-Teile bewirtschaftet. Für Reparaturen sind die notwendigen Bauteile lokal zu beschaffen. Die Spezifikationen von Spezialbauteilen finden Sie in der Serviceanleitung.

SMD Components

SMDs should only be replaced by skilled specialists. No warranty claims will be accepted for circuit boards that have been ruined. Proper and improper SMD soldering joints are depicted below.

Studer does not keep any commercially available SMDs in stock. For repair the corresponding devices should be purchased locally. The specifications of special components can be found in the service manual.

EMV / EMC

Störstrahlung und Störfestigkeit

Das Gerät entspricht den Schutzanforderungen auf dem Gebiet elektromagnetischer Phänomene, wie u.a. in den Richtlinien 89/336/EWG und FCC, Part 15, aufgeführt:

1. Vom Gerät erzeugte elektromagnetische Strahlung ist soweit begrenzt, dass bestimmungsgemässer Betrieb anderer Geräte und Systeme möglich ist.

2. Das Gerät weist eine angemessene Festigkeit gegen elektromagnetische Störungen auf, so dass sein bestimmungsgemässer Betrieb möglich ist.

Das Gerät wurde getestet und erfüllt die Bedingungen der im Kapitel „Technische Daten“ aufgeführten EMVStandards. Die Limiten dieser Standards gewährleisten mit angemessener Wahrscheinlichkeit sowohl den Schutz der Umgebung wie auch entsprechende Störfestigkeit des Gerätes. Absolute Garantie, dass keine unerlaubte elektromagnetische Beeinträchtigung während des Betriebes entsteht, ist jedoch nicht gegeben.

Um die Wahrscheinlichkeit solcher Beeinträchtigung weitgehend auszuschliessen, sind u.a. folgende Massnahmen zu beachten:

• Installieren Sie das Gerät gemäss den Angaben in der Betriebsanleitung, und verwenden Sie das mitgelieferte Zubehör.

• Verwenden Sie im System und in der Umgebung, in denen das Gerät eingesetzt ist, nur Komponenten (Anlagen, Geräte), die ihrerseits die Anforderungen der obenerwähnten Standards erfüllen.

• Sehen Sie ein Erdungskonzept des Systems vor, das sowohl die Sicherheitsanforderungen (die Erdung der Geräte gemäss Schutzklasse I mit einem Schutzleiter muss gewährleistet sein), wie auch die EMV-Belange berücksichtigt. Bei der Entscheidung zwischen sternoder flächenförmiger bzw. kombinierter Erdung sind Vor- und Nachteile gegeneinander abzuwägen.

• Benutzen Sie abgeschirmte Kabel, wo vorgesehen. Achten Sie auf einwandfreie, grossflächige, korrosionsbeständige Verbindung der Abschirmung zum entsprechenden Steckeranschluss und dessen Gehäuse. Beachten Sie, dass eine nur an einem Ende angeschlossene Kabelabschirmung als Sende- bzw. Empfangsantenne wirken kann (z.B. bei wirksamer Kabellänge von 5 m oberhalb von 10 MHz), und dass die Flanken digitaler Kommunikationssignale hochfrequente Aussendungen verursachen (z.B. LS- oder HC-Logik bis 30 MHz).

• Vermeiden Sie Bildung von Masseschleifen oder vermindern Sie deren unerwünschte Auswirkung, indem Sie deren Fläche möglichst klein halten und den darin fliessenden Strom durch Einfügen einer Impedanz (z.B. Gleichtaktdrossel) reduzieren.

Electromagnetic Compatibility

The equipment conforms to the protection requirements relevant to electromagnetic phenomena that are listed in the guidelines 89/336/EC and FCC, part 15.

1. The electromagnetic interference generated by the equipment is limited in such a way that other equipment and systems can be operated normally.

2. The equipment is adequately protected against electromagnetic interference so that it can operate correctly.

The unit has been tested and conforms to the EMC standards applicable to residential, commercial and light industry, as listed in the section „Technical Data“. The limits of these standards reasonably ensure protection of the environment and corresponding noise immunity of the equipment. However, it is not absolutely warranted that the equipment will not be adversely affected by electromagnetic interference during operation.

To minimize the probability of electromagnetic interference as far as possible, the following recommendations should be followed:

• Install the equipment in accordance with the operating instructions. Use the supplied accessories.

• In the system and in the vicinity where the equipment is installed, use only components (systems, equipment) that also fulfill the above EMC standards.

• Use a system grounding concept that satisfies the safety requirements (protection class I equipment must be connected with a protective ground conductor) that also takes into consideration the EMC requirements. When deciding between radial, surface or combined grounding, the advantages and disadvantages should be carefully evaluated in each case.

• Use shielded cables where shielding is specified. The connection of the shield to the corresponding connector terminal or housing should have a large surface and be corrosion-proof. Please note that a cable shield connected only single-ended can act as a transmitting or receiving antenna (e.g. with an effective cable length of 5 m, the frequency is above 10 MHz) and that the edges of the digital communication signals cause high-frequency radiation (e.g. LS or HC logic up to 30 MHz).

• Avoid ground loops or reduce their adverse effects by keeping the loop surface as small as possible, and reduce the noise current flowing through the loop by inserting an additional impedance (e.g. commonmode rejection choke).

1 INTRODUCTION

On-Air 2000 Digital Mixing Console

On-Air 2000 is a low-cost yet powerful digital mixing console for “on-air” and small recording and editing studio applications. It has a modularity of 6 channels; the maximum console size is limited to 24 channel strips (stereo or mono).

On-Air 2000 is based on a touch-screen user surface. Only the most important functions have hardware control elements. Unlike other digital mixing consoles, On-Air 2000 does not need external racks and power supply. Everything is integrated in a single, lightweight console.

Since it is fully digital, it can be adapted to the current user using snapshot automation. Extensive configuration possibilities allow On-Air 2000 to be integrated into almost any broadcast studio environment.

For an overview, please refer to the On-Air 2000 block diagram located on the following two pages.

2 GENERAL

2.1 Utilization for the purpose intended

The On-Air 2000 mixing console is intended for professional use. It is presumed that the unit is operated only by trained personnel. Servicing is reserved to skilled technicians. The electrical connections may be connected only to the voltages and signals designated in this manual.

2.2 First steps

2.2.1 Unpacking and inspection

Your new mixing console is shipped in a special packing which protects the units against mechanical shock during transit. Care should be exercised when unpacking so that the surfaces do not get marred. Verify that the content of the packing agrees with the items listed on the enclosed shipping list. Check the condition of the equipment for signs of shipping damage. If there should be any complaints you should immediately notify the forwarding agent and your nearest Studer distributor. Please retain the original packing material because it offers the best protection in case your equipment ever needs to be transported.

On-Air 2000 Digital Mixing Console

2.2.2 Installation

Primary voltage: The power supply unit is auto-ranging; it can be used for mains voltages in

General precautions: Do not use the unit in conditions of excessive heat or cold, near any source

Power connection: The attached female IEC 320/C13 mains cable socket has to be connected to

a range of 100...240 VAC

of moisture, in excessively humid environments, or in positions where it is likely to be subjected to vibration or dust. Do not use any liquids to clean the exterior of the unit. A soft, dry cloth or brush will usually do. For cleaning the touch-screen display windows, most of the commercially available window or computer/TV screen cleaners are suited. Use only a

slightly damp (never wet) cloth. Never use any solvent!

an appropriate mains cable by a trained technician, respecting your local regulations. Refer to the “Installation, Operation, and Waste Disposal” section at the beginning of this manual. Maintenance work inside the units must be performed by a trained technician.

Date printed: 05.10.99 General E2/1

On-Air 2000 Digital Mixing System

Earthing: This equipment must be earthed, due to the mains input filter network be-

ing connected to the mains earth.

Some consideration should be given to the earthing arrangement of the system at the center of which is the console. The console chassis is earthed to the mains earth via the power supply. Ground loops may occur where signal processing equipment, patched to the console, has its signal earth commoned to the equipment chassis.

2.2.3 Adjustments, repair

Danger: All internal adjustments as well as repair work on this product must be per-

formed by trained technicians!

Replacing the supply unit: The primary fuse is located inside the power supply module and cannot be

changed. In case of failure, the complete supply unit must be replaced. Please ask your nearest Studer representative.

2.2.4 PC-card

A standard On-Air 2000 mixing console is equipped with a PC-card socket. Using the industry-standard SRAM PC-cards, the user can save important console information on a card. This information can then be used to restore the console to the same state at a later moment. Since the information stored on the card is DOS compatible, it is easily transferred to an IBM-compatible PC for data storage and backup.

Note: Although it is possible to format an SRAM card in a PC, the card must be

re-formatted in the On-Air 2000; therefore, the write protect tab must be set to OFF when the card is used in the mixing console for the first time.

It is also possible for new software releases to be downloaded from an SRAM PC-card. This feature is only available for users in possession of the correct files. For more information on this subject, refer to section 13.

The mixing console PC-card support is restricted to 5 V, Type 1, SRAM memory cards with a capacity of 64 kbytes to 32 Mbytes. Hot-swapping is supported, too.

3 OPERATING CONCEPT

The normal operation of the console is as simple as possible. This has been achieved by reducing the number of operating elements to the minimum. Nevertheless, high flexibility has been achieved thanks to the use of touchscreen technology which just shows those operating elements which are needed at a certain time.

A channel fader and three buttons (ON, OFF, PFL) are the only hardware operating elements in a channel strip. All other functions are available through the touch-screens. To maintain a good console overview these touch-screens (channel screens) are located right above the channel strips. Symbols on the screens show the current settings on every channel. Touching one of the symbols assigns the center touch-screen (control screen) to this function. Parameters can now be entered via the four rotary encoders (e.g. equalizer parameters), or directly through the assigned touch-screen (e.g. equalizer on/off). On the screen above the channel strips, the new settings are immediately updated. The On-Air 2000 concept has all current settings for every channel visible at any time. This innovative user surface is called the “Touch’n’action” concept and is patented.

On-Air 2000 Digital Mixing Console

In broadcast applications many DJs and operators without a special technical education work on the same mixing console. Every DJ has his preferred console settings, mainly EQ parameters for his microphone. In the On-Air 2000, individual settings can be stored; by simply pressing a key, every operator can recall her or his particular, tailor-made setting and concentrate afterwards upon her/his essential task – presenting a radio program meeting the needs of the listeners. Radio stations often use the same mixing console type for on-air and production. The “Snapshot” feature easily turns the production console into an on-air console within seconds, if required.

4 CHANNEL FUNCTIONS

On-Air 2000 is modular in groups of 6 channels; the maximum number of channels is 24. Each channel group consists of a touch-screen, 6 faders, 18 keys (3 per channel) and 6 overload indication LEDs.

4.1 Keys

The channel key functions are configurable; this configuration is valid for the whole console (and not per channel). The different configuration possibilities are:

Configuration Key 1 Key 2 Key 3

On-Air 2000 Digital Mixing Console

1 2 3 4

PFL ON OFF PFL ON/OFF LOCATE PFL ON LOCATE PFL ON/OFF NEXT

For details on the configuration see section 9.

4.2 Faders

Since the audio path is fully digital, the signal does not pass through the faders. Therefore linear-track mono faders are used. The stroke length is 104 mm. When opening the fader, fader start or signaling commands can be released, depending on the configuration (see section 9).

Master faders: Starting with SW V3.0, any of the faders can be configured as master

fader(s) for the program and/or the record bus (see section 5.13).

4.3 Overload indicator

A red OVL indicator per channel signalizes an overload condition anywhere within the signal processing path.

Signals in the On-Air 2000 are processed with sufficient headroom through the entire signal processing chain. Besides, most outputs (PGM, REC, AUX1, AUX2, SEND1...4) are equipped with limiters in order to prevent overloads. All limiters are set to 0 dBFS with fixed attack and release times. Overload on a channel is indicated if the signal level enters the headroom range. Due to the internal headroom and the output limiters, normally distortion can be avoided in case of an overload.

Date printed: 05.10.99 SW V3.0 Channel functions E4/1

On-Air 2000 Digital Mixing Console

4.4 Channel screen

A channel screen is located above each group of six faders. The channel screen has a touch matrix with 2 × 6 switch fields per channel strip as shown below.

The channel screen always maintains system overview by displaying the relevant settings of the six input channels. When touching one of the switching fields, the central control screen automatically displays the attached operating field and allows entering parameters. In the channel screen, the status display is immediately updated.

In the following sections we assume that the user has access permission to all functions, unless otherwise noted. access permission may be limited, which causes that certain screen parts are suppressed. Full access permission is in such a case only obtained when entering a password. For a description of how to set up the access permission, refer to section 11.

4.4.1 Channel screen fields

Input selector field: For microphone and analog/digital line inputs, the Input selector field di-

rectly selects one of two input signal sources. The selected input is highlighted, and the source name appears in the Source label field. If the channel is active (i.e. channel ON, fader opened and output bus selected), the input selection is disabled. If the input module for that channel is a multi-source selector for six sources, the source selection can be made in two different ways depending on the Customer Code setting (section 12.2.12):

E4/2 Channel functions SW V3.0 Date printed: 05.10.99

On-Air 2000 Digital Mixing Console

Customer Code 0: When touching the input selector field, a Source Selector page appears on

the central control screen and allows selecting one of the six connected sources. The input selector field displays the currently selected input of the channel (in the illustration on the previous page the channel at the far right).

Customer Code 1: The six input selection fields are always displayed on the channel screen; the

Input and AUX fields are omitted (in the illustration below the channel at the far right).

If the channel is connected to an automation system, the input selector field shows “ON AIR” if the channel is on-air, or it shows “NEXT” if this is the next channel to be switched on-air. For more details on this topic, please refer to section 10.

Input field: The input field gives an overview of the console’s relevant front-end pa-

rameters. For a line or digital input channel, these parameters are:

Phase: NORM/INV (normal, or left channel inverted).

Stereo mode: LR/RL/LL/RR/MONO (normal stereo, channels swapped, left input to both

outputs, right input to both outputs, or mono signal to both outputs).

Calibration: ±10 dB (deviation of nominal level).

The microphone inputs have the following parameters:

Phase: NORM/INV (normal or inverted).

Phantom power: 48 V OFF/48 V ON.

Gain: 0...+70 dB (microphone input amplifier gain).

The underlined settings are the default values. If a parameter setting is different from its default value, it is highlighted on the channel page field.

A touch on the Input field does not change a parameter, but opens the Channel Control page on the central control screen. Parameters can now be entered with the four rotary encoders and the control screen touch switches.

EQ/filter field: The EQ/filter field is a graphical display of the equalizer setting. “EQ” is

highlighted if a filter or the equalizer is on. Touching this field opens the Equalizer page on the control screen.

AUX field: The potentiometer symbols in the AUX field show the auxiliary settings.

Both auxiliaries can be independently set as “AF” (post-fader), “PF” (prefader), “ON”, or “OFF”. “PF” and “ON” are highlighted if selected. Auxiliary settings are changed on the Channel Control page on the central control screen which is opened by touching the “AUX” field.

Date printed: 05.10.99 SW V3.0 Channel functions E4/3

On-Air 2000 Digital Mixing Console

PAN/BAL field: The PAN/BAL field gives an overview of the current panorama or balance

setting and shows the bus assignment. The output sum symbol (Σ) is high- lighted if the channel is assigned to the programme output (ΣPGM) or to the recording output (ΣREC). The Channel Control page on the central control screen is opened by touching the PAN/BAL field.

Source label field: The Source label field shows the name of the selected input channel.

“Next” function: This function allows highlighting the source label of the channel being the

next to go on-air. For this purpose just touch the desired channel's source label. Only one source label can be highlighted at a time. The tag is automatically removed when the fader of this channel is opened while the channel is ON. This function has no influence neither on control output signals nor on the internal functionality of the console.

4.4.2 Multi-Source Selector page

The Source Selection page on the central control screen is opened by touching the Input Selector field of a channel, provided the channel is equipped with a multi-source selector input module. On the Source Selector page, one of the six inputs can be selected and then becomes highlighted. The input name is shown on the channel label field on the channel page. The source selection page appears only if the hex input modules are configured for central selection (i.e. Customer Code 0).

E4/4 Channel functions SW V3.0 Date printed: 05.10.99

4.4.3 Channel Control page, microphone input

The Channel Control page for a microphone input is opened if either the AUX, the PAN, or the Input field on the channel page is touched, provided that the selected input module is a mic input.

Touching the “ON” part of the PHANTOM field turns the 48 V phantom power on; a touch on the “OFF” part of the field turns it off again. The status is indicated by highlighting the corresponding field. Phase inversion of the microphone signal is activated by touching the “INV” part of the PHASE field; “INV” is highlighted. Touching “NORM” deactivates the phase inversion. The microphone preamp's gain is set with the first rotary encoder (in a

0...+70 dB range); the adjusted value is indicated in the GAIN field. The AUX 1/2 “ON/OFF” fields route the channel to the corresponding auxiliary bus, if “ON” is selected (and highlighted). The “AF/PF” field allows selection whether the signal is taken after- (AF) or pre-fader (PF). The current selections are highlighted. The AUX levels (–∞...+10 dB; 0 dB position is marked with a dot) are adjusted with the second and third rotary encoder. The settings are shown in the fields right above the rotary encoders as well as on the corresponding symbols on the channel page. The bus assignment is performed with the “ΣPROGRAM” and “ΣREC- ORD” fields. The fourth rotary encoder positions the source within the stereo image, the PAN indicator shows the adjusted position.

4.4.4 Channel Control page, line input

The Channel Control page for a line input is opened if either the AUX, the PAN, or the Input field on the channel page is touched, provided that the selected input module is an analog line input or a digital input.

Line level inputs have a MODE field which defines whether the input is processed in “ST”(ereo) or in “MONO” mode. In mono mode the stereo input signal from the input module is added to a mono signal and attenuated by 3 dB.

Stereo signals are processed in the following modes:

LR: Normal stereo mode; RL: Left/right channel swapped; LL: Left signal on both channels; RR: Right signal on both channels.

Phase inversion (of the left-channel signal only) is activated by touching the “INV” part of the PHASE field; “INV” is highlighted. Touching “NORM” de-activates the phase inversion. Only in the “RR” case, the phase inversion takes place in the R input path.

The following diagram shows the details:

In the CAL field, the gain deviation referred to nominal level setting is displayed; max. deviation: ±10 dB, adjustment with the first rotary encoder. The AUX 1/2 “ON/OFF” fields route the channel to the corresponding auxiliary bus, if “ON” is selected (and highlighted). The “AF/PF” field allows selection whether the signal is taken after- (AF) or pre-fader (PF). The current selections are highlighted. The AUX levels (–∞...+10 dB; 0 dB position is marked with a dot) are adjusted with the second and third rotary encoder. The settings are shown in

the fields right above the rotary encoders as well as on the corresponding symbols on the channel page. The bus assignment is performed with the “ΣPROGRAM” and “ΣREC- ORD” fields. The fourth rotary encoder adjusts the position of the stereo image, the BAL indicator shows the adjusted position.

Access permission: Depending on the access permission (see section 11) of the user currently

logged in, the functions not available to this user will not be displayed on the Channel control page; an example is given below. This user cannot access the following parameters:

• PHASE

• AUX 1

• Output summing busses (ΣPROGRAM, ΣRECORD)

• PAN/BAL.

If the user has no access permission at all, the Channel Control page will not be displayed.

4.4.5 Equalizer control page, microphone input

The Equalizer control page for microphone inputs is opened if the EQ/Filter field of the channel page is touched, provided that the selected input module is a microphone input. If the user has no access permission to the EQ parameters, the Equalizer control page will not be displayed.

The HPF “ON/OFF” field is a high-pass filter switch. The filter is part of the analog front end and is available on microphone inputs only. “ON” is highlighted if the filter is active. The EQ “ON/OFF” fields activate or bypass the equalizer. If the EQ is bypassed (i.e. “OFF”), the preset frequency curve is displayed on the central control screen nevertheless. In the EQ/Filter field of the input channel, however, the current, linear frequency response is displayed. The four rotary encoders are the control elements for the equalizer. The lowfrequency section is a shelving-type filter with two selectable turnover frequencies and variable boost/cut. The frequency is selected by the left-hand “CUTOFF” touch fields, the gain is set with the leftmost rotary encoder. The next rotary encoder sets the frequency of the mid-frequency section which is a peaking-type filter. The third rotary encoder controls the midfrequency gain. The rightmost rotary encoder controls the gain of the highfrequency section which again is a shelving-type filter with two turnover frequencies. The right-hand “CUTOFF” fields allow frequency selection of the high-frequency shelving filter. The current EQ frequency response curve is displayed on the page.

Note: The HF cutoff frequencies can be reduced by approx. one octave (resulting

in an increased filter effect) when selecting Customer Code 0x00000002, refer to section 12.2.12.

The equalizer has the following specs:

5 MASTER FUNCTIONS

Master functions are not channel-related but global functions. These are audio functions (AUX master level, studio monitoring), non-audio functions (telephone hybrid control, clock, stopwatch), snapshot management, and system configuration.

Pressing one of the keys AUX MASTER, TEL, STUDIO MON, MIXER SETUP or HOME will always lead to the corresponding page. This is important for all pages where the user usually gets out of a page by pressing the HOME key. Jumping to a different screen has the same reaction as pressing HOME.

5.1 Login/logout

The console always starts up in default mode. If the user is a registered user, and if he wants to work in his own environment, he must log-in. He has to touch the LOGIN key on the Mixer Setup page. The LOGIN page will appear where the user can touch the key with his own name.

On-Air 2000 Digital Mixing Console

More information on the login procedure can be found in section 11.5.

After having logged in, the LOGIN key changes to LOGOUT; when the user leaves the console, this key must be used. After having touched LOGOUT, a dialog box appears, asking for confirmation. This is used as a protection against logging out inadvertently.

If a console is operated by one person only, the Administrator simply has to enable all access rights for the default user. This is the way the user can

Date printed: 05.10.99 SW V3.0 Master functions E5/1

On-Air 2000 Digital Mixing Console

control all console functions (except the administration functions) without having to log-in. A default user is always defined in the User administration table. His name is DEFAULT USER. The access permissions of this user can be edited. His record cannot, however, be deleted, and no password can be defined for him.

5.2 AUX and Insert control

The AUX MASTER/INSERTS page is entered by touching the AUX & INSERT key on the central control screen. Access permission limitations: If the user has no access permission for the AUX and/or insert parameters, there will appear a text next to AUX MASTER and/or INSERTS, telling the user that he cannot modify the parameters.

AUX MASTER: The two rotary encoders below the AUX 1 and AUX 2 gain indication sym-

bols are used to adjust the desired level of the corresponding AUX master. The gain can be adjusted in a range of –∞ to +10 dB; the 0 dB position is marked with a dot. ON/OFF selection of the AUX master busses is done by touching the corresponding keys on the screen. A highlighted background indicates the current status. The AUX 1 and AUX 2 gain indication symbols are always displayed, even if no output module is installed for AUX 1 and AUX 2.

INSERTS: On the same page, the four insert points can be assigned. Assignment is

possible to any of the following signals:

• CH1...CH24,

• PROGRAM bus,

• RECORD bus,

• NONE. A channel can be assigned by touching the channel/bus label field of the insert box. If the insert is set to OFF, the channel/bus label field is highlighted by touching it, then it can be changed with the rightmost rotary encoder. If the insert is set to ON, the channel/bus label field cannot be highlighted, and the insert assignment cannot be changed. The insert send always follows the setting as displayed on the screen; it is remains active while the insert is switched OFF. If the insert is switched ON, a switchover from the internal connection to the insert return is performed.

E5/2 Master functions SW V3.0 Date printed: 05.10.99

On-Air 2000 Digital Mixing Console

Each signal can be assigned to one insert only. If a signal is already assigned to an insert, it will not appear in the channel/bus label field during signal selection for an other insert. Inserts are assigned per channel and not per input. An insert assignment is valid for both inputs of the module (or for all six inputs in case of a hex input module). The insert assignment and the insert ON/OFF setting are included in snapshots. If an insert module is removed, the insert assignments are disconnected (OFF, NONE) and will be visible on the AUX MASTER/INSERTS page no more.

5.3 N–1/audition master and telephone hybrid control

Two clean-feeds (N–1A, N–1B) are provided; they can be used as mono outputs to telephone hybrids or line outputs. The audition bus can either be used as a special monitoring bus (all sources but the microphone channels can be heard if a microphone is open), or as a third, mono or stereo cleanfeed. Access permission limitations: If the user has no access permission for the clean-feed and/or audition bus parameters, there will appear a text next to the corresponding field, telling the user that he cannot modify the parameters.

The clean-feeds as well as the audition bus have master level controls which can be accessed if the N–1/audition master and telephone hybrid page is opened by touching the TEL/N–1/AUDIT key on the central control screen. The output levels are controlled with three of the rotary encoders; the output gain range is –∞...+10 dB, the 0 dB position is marked with a dot.

Two telephone hybrid units to which the clean-feeds are fed can be controlled from the On-Air 2000 user surface, if an (optional) telephone hybrid control module is installed. In such a case the ON-AIR, HOLD, and TELEPHONE keys appear on this page. TELEPHONE switches the telephone line to the telephone. By touching HOLD, the telephone line is routed to the telephone hybrid unit. The return channel is connected, but the incoming channel is not connected to the console. Only when touching ON-AIR both the incoming and the return channel are connected to the console.

5.3.1 Additional N–1 outputs

Starting with SW V3.0, four additional N–1 outputs (N–1C...F) are available, if no Insert 3/4 module is installed in the console. Their respective levels are also part of a Snapshot.

Conditions: • A standard Dual Analog Output Module must be installed in order to bring

the four N–1 signals out of the console;

• Output mode must be set to “Stereo”;

• The following bus assignment is required:

OUT1 left = N–1C, right = N–1D, OUT2 left = N–1E, right = N–1F;

Note: The stereo output mode selection and the bus assignment is performed with

jumpers on the Dual Analog Output Module; refer to section 15.18.

• When upgrading from an earlier SW version, a hardware modification is required on the DSP Board – please ask your Studer distributor for additional information.

PRIVATE/GLOBAL: Users can select between private and global snapshot pages.

SYSTEM CONF.: This key leads to the second level of mixer setup functions. These are acces-

sible only for users having the corresponding parameter set in the user configuration. A new page is displayed, allowing to select from several groups of configuration parameters.

USER ADMIN.: Only the administrator has access to the user administration page.

In the following sections, the use of snapshots and mic settings is described, followed by some information on user administration and the watch/stopwatch functions.

5.6 Snapshots

A snapshot is a copy of a momentary console setup. It contains all parameters (as input selection, input gain, phase, phantom power, balance or panorama setting, EQ settings, AUX settings), except fader positions, PFLs, and ON/OFF keys. A snapshot does not contain any parameters being part of the console configuration (channel labels, control signal functions, cleanfeed bus assignment, level meter assignment, etc.). Each user having a personal password can store up to four private snapshots (max. 20 users), and up to five global snapshots being available for every user can be stored in the console's flash memory. More snapshots can be stored on a PC-card (refer to section 5.8) and written from the card into the console's flash memory if required. A name can be given to every snapshot which is displayed in the leftmost key column. Also refer to section 5.9.1 for information on snapshot access rights.

5.6.1 Recall a snapshot from memory

On-Air 2000 Digital Mixing Console

Select a snapshot by touching one of the name keys. The name of the selected snapshot is highlighted. When pressing the RECALL FROM MEMORY key, the snapshot will immediately be recalled from the console's internal flash memory, except if the current channel is active (switched to the program or the record bus); then the recall operation is delayed until the channel is closed. During execution of the snapshot RECALL function, the system compares the configuration parameters of each channel (input type, number of inputs) with the configuration parameters saved together with the snapshot. If there is a mismatch, the snapshot will not be executed for this channel.

On-Air 2000 Digital Mixing Console

5.6.2 Save a snapshot to memory

Saving a snapshot is done by touching a snapshot key, followed by SAVE MEM. The keyboard page appears where the snapshot name can be entered or edited (max. 20 characters). If the existing name is to be kept, just touch the <--¦ ENTER key.

CLEAR is used to clear the EDIT TEXT field for entering a new name with the keyboard. <--- BACK is used to delete one character to the left of the cursor. EXIT is used to leave the keyboard page without saving the new name. When pressing <--¦ ENTER, the keyboard page is left and the snapshot data are saved.

Note: Global snapshots can be saved by the system administrator only. Logged-in

users can save their private snapshots only.

5.6.3 Delete a snapshot from memory

When saving a snapshot the previously stored snapshot data are overwritten. A snapshot can be deleted, too, without overwriting it with new data. For deleting a snapshot from the console's internal flash memory, the desired snapshot has to be selected. The selected key is highlighted. After touching the DELETE MEM key a dialog box appears. If it is confirmed, the snapshot will be definitively removed from the memory and the name within the selected key is cleared.

5.7 Microphone settings

A microphone setting is a set of equalizer and gain parameters (EQ, gain, phase, phantom power) for a single microphone channel. Thus, every DJ or announcer can store his preferred microphone settings and recall them at any time. Up to four private microphone settings for each user (max. 20 users), and up to ten global microphone settings can be stored in the console's flash memory; additional microphone settings can be stored on a PC-card as well (refer to section 5.8). Microphone settings can be named, as the snapshots; these names are displayed on the two key columns in the center of the Mixer setup page.

5.7.1 Recall a microphone setting from memory

To recall a microphone setting from the console's internal flash memory, first a microphone input channel has to be selected by pressing the MIXER SETUP key, followed by the corresponding MIC SETTING key. The name of the selected microphone setting is highlighted. Then touch the RECALL FROM MEMORY key. The selected channel’s parameters are immediately set to the values of the microphone setting. Selection of another type of input (line or digital) is treated as an error and will not be accepted by the system.

On-Air 2000 Digital Mixing Console

If the last modification was made on a microphone channel, this channel is automatically selected and displayed in the top line of the mixer setup page. If the user wants to change the input selection, he touches the label field of the desired channel in the channel screen. The input being currently active (A or B) of this channel is now selected and shown in the top line of the mixer setup page.

5.7.2 Save a microphone setting to memory

Creating a microphone setting means saving a set of equalizer and gain parameters for a single microphone channel under a given name into the console's internal flash memory. This is done by first selecting the microphone channel to be stored, then touching a MIC SETTING key, followed by SAVE MEM. The keyboard page appears where the microphone setting's name can be edited. Any MIC SETTING key (also one of these which have already been used and have a name assigned) can be selected. It will, however, be overwritten by the new mic setting.

Now a new name can be generated, or the already present name can be overwritten or edited. When pressing <--¦ Enter, the microphone setting data and its new name is saved.

5.7.3 Delete a microphone setting from memory

When saving a microphone setting the previously stored data are overwritten. A microphone setting can be deleted, too, without overwriting it with new data. For deleting a microphone setting from the console's internal flash memory, the desired microphone setting has to be selected. The selected key is highlighted. After touching the DELETE MEM key, a dialog box will appear. If it is confirmed, the microphone setting will be definitively removed from the memory, and the text within the selected key is cleared.

E5/10 Master functions SW V3.0 Date printed: 05.10.99

5.8 Using PC-cards

Snapshots and mic settings can also be saved to a PC-card and loading them from the card into the console's flash memory. Using PC-cards, parameter settings of a console can be copied to an other one, provided that both have the same configuration. A PCMCIA card with a capacity of 64 kB can hold about 20 snapshots. On a 4 MB card, the complete console software and the configuration and parameter data of the console.

5.8.1 Load a snapshot/mic setting from PC-card

To load a snapshot or a microphone setting from a PC-card, LOAD FROM CARD must be pressed. The following page will be displayed:

On-Air 2000 Digital Mixing Console

Snapshots or mic settings can only be loaded as long as there are sufficient empty snapshots or mic settings available in the console's flash memory. They can be selected for loading by scrolling with the corresponding << or >> keys, followed by LOAD. After having loaded a snapshot or mic setting, it is not automatically active, but it is just available in the Mixer Setup page and must be recalled with RECALL FROM MEMORY, as described in

sections 5.6.1 and 5.7.1, respectively.

5.8.2 Save a snapshot/mic setting to PC-card

To save a snapshot or a mic setting to a PC-card, first a snapshot or a mic setting must be selected in the Mixer Setup page. Then the SAVE CARD key must be pressed. A keyboard appears for entering a file name (max. 8 characters), as described in sections 5.6.2 and 5.7.2 . After confirmation with ENTER, the snapshot or the mic setting is saved on the card. If an empty file name is entered or EXIT is pressed, the action is cancelled without saving anything to the PC-card.

Date printed: 05.10.99 SW V3.0 Master functions E5/11

On-Air 2000 Digital Mixing Console

Exceptions: If the file name already exists on the PC-card, the action must be confirmed

before the file is overwritten. If a user with an other password tries to store a file under an already existing file name which has not been given by him, he will not be able to overwrite this particular file (only the administrator is allowed to overwrite all files). If the card is full, a dialog box appears, telling that the file cannot be saved.

File name extensions: The three-character DOS file name extensions on the PC-card will be gener-

ated automatically. The relationship between the file name extension and the file content is shown in the following table.

Data type File name extension

Global snapshot .gss

Private snapshot .pss

Global mic setting .mis

Private mic setting .mip

5.8.3 Delete a snapshot/mic setting from PC-card

To delete a snapshot or a mic setting from the PC-card, DELETE CARD must be pressed. The following page is displayed:

A snapshot or a mic setting can be selected for deleting by scrolling with the corresponding << or >> keys. The selected file and the snapshot or mic setting name which is contained in this file are displayed to the right of the << / >> keys. When pressing DELETE, the file is deleted definitively; once deleted, the data cannot be recovered.

A user can only delete his own, private data from the card. The administrator, however, has access to all (global and private) files on the card. Depending on what selection the administrator has made in the Setup page, either only the global or only the private files are displayed for him.

The DELETE FROM PC-CARD page remains until either EXIT or one of the main menu keys is touched.

5.9 Administrator

5.9.1 Features

On-Air 2000 Digital Mixing Console

• No private snapshots for the administrator.

• The administrator has access to all private and global parameter settings.

• Only the administrator has access to the SYSTEM CONF. and USER ADMIN. keys.

The administrator's Mixer Setup page is shown above. In this case all SAVE, DELETE, RECALL, and LOAD actions correspond to global snapshots and mic settings. When the administrator touches the PRIVATE key and selects one of the users, he can modify her or his private settings (see section 5.9.2). A normal user (which is not logged in as administrator) has only access to global snapshots and mic settings and to her/his own private snapshots and mic settings.

Summary: The displayed snapshots and mic settings depend on the type of user logged-

in to the console. A user which has entered no password can access private settings, too; these will, however, not be password protected and can be overwritten by any other user not being logged-in to the console. Global parameter settings can be recalled by any user but modified by the administrator only.

5.9.2 Administrator selection of snapshots/mic settings

The administrator can display and modify the private snapshot and mic setting data. After selecting PRIVATE in the SNAPSHOTS/MIC SETTING page, the second rotary encoder from the left (the one below the users name label) allows to select the user's name. In this mode the administrator can LOAD, RECALL, SAVE, or DELETE all of the data being displayed.

This feature has been implemented in order to enable the setting of parameters in a private snapshot or mic setting to which the particular normal user has no access. All actions such as RECALL FROM MEMORY, SAVE MEM, DELETE MEM, LOAD FROM CARD, SAVE CARD, and DELETE CARD concern the selected user's data. All other actions on the console cannot be affected.

5.9.3 Users with and without a password

When a normal user enters the Mixer Setup page before logging-in (which means he is treated as default user), he works with the default user's data. He can LOAD, RECALL, SAVE, or DELETE all of the default user's data in the console's memory or on the PC-card. These data can, however, be used, saved, overwritten, or deleted by any other user, who is not logged-in as well. The Mixer Setup page offers a PRIVATE key to the left of the GLOBAL key, allowing the user – after he has logged-in – to access his own, protected private snapshots and mic settings. Should the user have access permission to the system configuration, then the SYSTEM CONF. key would be displayed, too.

E5/14 Master functions SW V3.0 Date printed: 05.10.99

On-Air 2000 Digital Mixing Console

A user can decide to work with the global data although he is already logged-in. If the GLOBAL key is pressed, the Mixer Setup page will look as shown below, where he can recall (but cannot modify) the global snapshots and mic settings. If the user has access permission to the system configuration, the SYSTEM CONF. key would be displayed, too.

5.10 User administration

USER ADMINISTRATION is only accessible by the administrator. Refer to section 11 for details on how to set up function access permission and new user accounts.

5.11 System configuration

System configuration is a separate function group which can be accessed only by the administrator or by users having access permission. It is separately described in detail (refer to section 12).

5.12 Watch and stopwatch

The watch and stopwatch functions are continuously displayed on the righthand side of the central screen.

The term “watch” refers to the time of day in analog and digital format, the day of the week and date in an abbreviated format. The term “stopwatch” refers to both the fader and the user stopwatches. The fader stopwatch measures the time the most recently used channel fader has been opened. The user stopwatch works like a normal stopwatch with START/STOP and RESET keys located directly below the display screen.

Below, the HOME page with the watch and stopwatch displays and functions is shown.

5.12.1 Watch

The watch gives a permanent time, day of week, and date display. The normal time reference is an internal, battery-buffered real-time clock (RTC). The RTC continues to run even when the console is switched off. Therefore it is unnecessary to set the watch at power-up. The RTC can also by synchronized by an optional TimeSync Module connected to the control module bus. If synchronization is established, the top right corner of the central screen shows an “S” (sync OK). Changes to the internal time reference and the time and date format can be made by the administrator on the TIME page (MIXER SETUP, SYSTEM CONFIG., TIME). For details, refer to section 12.2.5.

Both time and date can be displayed in two formats, as shown below:

Time format Digital time indication

12:00 p.m. 12 hour time format

24:00 24 hour time format

5.12.3 User stopwatch

On-Air 2000 Digital Mixing Console

The upper of the two stopwatches is called the fader stopwatch. It always restarts at 00:00:00 when a new input channel is activated (e.g. channel ON, fader open, and output bus selected). In other words, it displays the elapsed time of the last channel opened. This function can be enabled or disabled for any desired channels via the MIXER SETUP/SYSTEM CONFIG./INPUT menu, item TIMER START YES/NO. The counter stops when the channel which has started the stopwatch is switched OFF, or its fader is closed.

the last channel’s time is displayed.

The user stopwatch is located just below the fader stopwatch. It is controlled by two keys on the console’s surface located below the digits of the display. One key starts and stops the timer, the other resets the timer.

5.13 Master fader for PGM and REC outputs

Starting with SW V3.0, any of the 24 faders – i.e. even faders the number of which is higher than the number of channels the console is configured for – can be configured as master fader(s) for the program and/or the record bus. This selection is performed with the two leftmost rotary encoders located below the PGM MASTER and REC MASTER fields (in the MASTER FADER ASSIGNMENT section on the COMMON SETTINGS page), followed by touching APPLY.

The corresponding input channel can still be used, however without control possibilities from the operating surface (i.e., only the external MUTE and Monitora control is available). In such a case, this channel may be used as a talkback mic input channel; please note that the TB SOURCE parameter of this input must then be set to “CR” in the INPUT CONFIG. page. If only fixed PGM MASTER and/or REC MASTER output levels are required, it is also possible to set them once and switch back to the normal channel control afterwards – just by selecting “NONE” in the PGM MASTER and REC MASTER fields on the COMMON SETTINGS page.

Important: When re-establishing standard console operation, please make sure that

the master levels are set back to 0 dB.

Specifications: • In the audio path, the master fader(s) is/are located before the insert points

(also refer to the block diagram in section 1);

• No ON/OFF function is available for the master busses;

• PFL function is available;

• Overload indication is available;

• Master level can be controlled by Monitora extended commands;

• Signaling (ON-AIR, CR-MIC, and STUDIO-MIC) and CR/Studio CUT/DIM as well as some restrictions of the graphical user interface consider the master faders.

Two additional keys are used to control the monitoring loudspeakers in the control room. The functions of these keys are described in the table below.

A volume control knob (MON ) is used to set the level sent to the CR monitor speakers. As long as one of the microphones in the control room (DJ or guest microphone) is on, the monitor speakers are muted. In this case the CUT key is illuminated. If the monitoring source is AUDIT (audition bus), the monitor speakers are either dimmed (DIM key illuminated), muted (CUT key illuminated), or not affected at all, according to the configuration (see section 12.2.2 for details). If talkback is active, the level of the monitor speaker is dimmed by 20 dB and the DIM key is illuminated.

External CR DIM: On from SW V2.02, an additional control input has been implemented, al-

lowing to reduce the level of the CR monitor speakers by 20 dB by an external signal (see section 15.12 for details).

The DJ microphone usually is the source for talkback from the CR. For mixing consoles with less than 24 channels, a separate talkback microphone is optionally available, including preamplifier, limiter, and A/D converter. Its main application is in production and editing control rooms where no DJ microphone is required; for details, refer to section 15.17.

The connection between DJ mic and Cleanfeed B (N–1B, e.g. telephone 2) is established for as long as this key is pressed. The connection between DJ mic and Cleanfeed A (N–1A, e.g. telephone 1) is established for as long as this key is pressed. The connection between DJ mic and Auxiliary 2 is established for as long as this key is pressed. The connection between DJ mic and Auxiliary 1 is established for as long as this key is pressed. The connection between DJ mic and the Studio is established for as long as this key is pressed.

The parallel studio interface allows the connection of three pushbuttons for talkback destination selection. The possible destinations are: CR, Cleanfeed 1 (N-1 A), and Cleanfeed 2 (N-1 B). For talkback from the studio the studio microphones are used.

The console’s built-in PFL/TB loudspeaker and the headphones are used for talkback listening in the CR, while in the studio the monitoring speakers and the headphones are used.

Any of the function keys F1...F5 can be configured as additional talkback target keys. This allows, together with the optional Monitor extension, e.g. talkback to the audition bus. This bus could therefore be used as a third cleanfeed bus (N–1 C).

7.3.1 Additional talkback functions

The new Monitoring Module w. TB return 1.942.180.20 as well as the new Extended Monitoring Module w. TB return 1.942.181.20 both provide an

additional TB line input (electronically balanced, on the “STUDIO MONITOR AUDIO” connector) as well as additional CR and studio control inputs (on the “EXT PFL CTRL” connector). Please refer to the pin assignment tables and the connection diagram in section 15.12.

7.3.2 Talkback settings

Starting with SW V3.0, talkback and signaling can be configured independently. The “SIGN.” setting (formerly labeled “MIC LOCATION”) in the INPUT CONFIG. page is used only for signaling (red light) and monitoring (cut and dim). The additional “TB SOURCE” parameter in the INPUT CONFIG. page sets the assignment of the input to the TB bus (NONE, from CR, or from Studio).

During talkback from the Studio, the studio speakers are dimmed only if at least one input is configured as “SIGN.” = STUDIO and “TB SOURCE” = STUDIO. The same applies for talkback from the control room.

Note: Configuration of talkback and signaling is also possible for analog or digital

line inputs, as shown by the following screenshots.

8 SIGNALING

On-Air 2000 Digital Mixing Console

For control room and studio, signaling is provided by means of opencollector outputs (9-pin D-type connector on the Monitoring module; for connection details, see section 15.12). One output is available for each of the following statuses:

• Control Room microphone is on-air,

• Studio microphone is on-air, and

• Any signal from the console is on-air (i.e., a fader is open, this channel's ON pushbutton is active, and its signal is routed to the PROGRAM and/or the RECORD bus). The CR-MIC and STUDIO-MIC indicators in the central operating section of the console are illuminated when the corresponding control output is active.

SIGN. Output Active if:

CR MIC OUT At least one input of a CR or DJ microphone is active (channel ON,

fader open, assigned to program or record bus).

9 MACHINE CONTROL

The On-Air 2000 provides different control inputs and outputs. These can be used e.g. for switching a channel on and off, or for starting, stopping, and cueing of the connected source unit (as CD players, tape recorders, or a CAB system).

Each audio input holds two control outputs and one control input on D-type connectors. The signals are:

• CTRL OUT 1 (normally used for fader start, but configurable for other functions; see section 9.2.1)

• CTRL OUT 2 (configurable functions see section 9.2.2)

• CTRL IN (configurable functions see section 9.3.1) The status of the output signals depends on the control elements of the channel strip (keys 1...3, fader, input selection, output routing), as well as on the console configuration.

Each channel consists of either two (A/B input module) or six (hex input module) audio inputs. Each audio input has its own control input and two control outputs allowing to control every external source separately.

Key 1/LED 1 The first key is always used to activate/deactivate the PFL function; if ac-

tive, LED 1 is illuminated. The PFL function can affect the CTRL OUT1 and/or CTRL OUT2 control signals, depending on the configuration. This configuration is performed in the center section of the INPUT CONFIG. page and is identical for all types of input modules.

Key 2/LED 2 The second key is used either to switch the channel ON or to toggle the

channel ON/OFF, depending on the configuration of key 3. This function affects the CTRL OUT1 control signal. LED 2 always indicates the channel's ON/OFF status.

Key 3/LED 3 The functionality of the third key depends on the console configuration. It

can act as channel OFF key or as a LOCATE function. The key 3 functionality is set in the COMMON SETTINGS page:

Console configuration (valid for all channels):

Key 3 (“OFF”) function Key 2 (“ON”) function

(Channel) OFF (Channel) ON

LOCATE (Channel) ON/OFF LOCATE (Channel) ON *

Channel ON/OFF affects the CTRL OUT1 control signal of the selected input, and the locate function defines the status of the CTRL OUT2 control signal of the selected input.

* This additional configuration possibility has been introduced with SW V3.0;

to protect a channel from being switched off inadvertently, the OFF function can be disabled. This setting is performed in the COMMON SETTINGS page; it is valid for all channels of the console simultaneously.

Note: If this setting is selected, no channel can be switched off by pressing a key –

therefore, either closing the fader must do, or an external pushbutton per channel has to be added. For this purpose, a CTRL IN control input per channel is provided; please refer to section 9.3.1. Select the option “CTRL. IN – EXT. ON/OFF” in the INPUT CONFIG. page.

LED 3 is illuminated if an external device indicates ready status using the CTRL IN input signal of the selected input, or if the CAB system indicates “ready for playback” using the serial remote interface (SET_FADER_START*FaderNr).

10 AUTOMATION

10.1 Introduction

Studer Digimedia system: Information on how to connect and operate the On-Air 2000 mixing console

On-Air 2000 Digital Mixing Console

On-Air 2000 has no built-in automation but supports external CAB (computer-assisted broadcast) systems. With software version V2.0, also a serial interface (RS232/RS422/RS485) can be used to communicate with the CAB.

with a Digimedia CAB system is given in the current Digimedia operating instructions.

The serial interface protocol is based on the “Schnittstellen Spezifikationen Regiepult” of DAS (Digitale Steuerungs- und Automationstechnik, Thomas Volgmann) furthermore called [MONPROT], which was defined by VCS and Siemens.

It was not the target to implement the complete [MONPROT]. The implementation in the On-Air 2000 is rather a subset of [MONPROT] to allow for the applications described in section 10.3.

For detailed information on the telegrams implemented in the On-Air 2000, please refer to the “Communication Protocol for Broadcast Automation” document [BCACOM] (available on request).

• Serial communication interface: Serial RS232/RS422/RS485 standard communication interface based on [MONPROT].

• 2 x 12 character text display per channel.

• Music and speech output: The CAB can control the output assignment (program/record bus) of the currently selected input of a channel.

• 6 × 6 input routing: The input selector of the On-Air 2000 provides an input routing, as each input can select between 2 or 6 input lines. This leads to a maximum matrix size of 6 × 6 inputs.

The On-Air 2000 does not support:

• Motor faders; instead, an auto take-over mode is implemented, see section

10.3.5.

• Fader routing; some consoles allow for a routing between input lines and sources (“Quellname”) as well as for an assignment of a source (“Quellname”) to any fader (“Fadernummer”). In contrast to the suggestion of [MONPROT], the On-Air 2000's implementation does not allow the faders to be routed to any source.

10.3 Application handling

10.3.1 Configuration for automation control

Channels must be assigned to the automation system in the configuration in order to be controlled by an external CAB system. The AUTOMATION CONFIG. page is reached from the SYSTEM CONFIG. page:

10.3.2 Routing

The AUTOMATION CONFIG. page allows each channel to be assigned to the CAB system.

As the hex input module allows selection of one input out of six, a 6 × 6 input routing is possible with six hex input modules (max. four hex modules are allowed for a 24-channel console, and six hex modules for 18-, 12-, and 6-channel consoles).

E10/4 Automation Date printed: 05.10.99

On-Air 2000 Digital Mixing Console

Source Selection The CAB selects a source (SELECT_SOURCE*Name command) by its

name (input name as configured in Input Configuration page within the OnAir 2000). On receipt of such a command, the On-Air 2000 looks for a channel providing an input signal, the input name of which matches the first eight characters of the desired name, converted into upper case. First it checks if any channel is already selected providing a signal with this name. If not, it looks for all channels not yet selected by the CAB providing a signal with this name on one of its inputs. If found, the On-Air 2000 selects this input (A...F). After that, this channel's number is communicated by the console to the CAB (SOURCE_SELECTED*FaderNr) as a handle for subsequent operations.

A channel can be selected by the CAB (SELECT_SOURCE), if the following conditions are met:

• It must be assigned to be controlled by CAB (YES) in the Automation Config. page, and

• The input module must be present.

After a channel is selected by the CAB, its behaviour changes as follows:

• Indication of “ON-AIR” or “NEXT” within input selector field;

• It accepts channel-related commands as “SET_FADER_LEVEL* FaderNr” telegram;

• It can indicate “display2” text from “SET_FADER_DISPLAY_2 *FaderNr” telegram within the source label field;

• It sends “FADERSTATUS*FaderNr, ...” to the CAB;

• It does not (de-)activate PFL on PFL key pressure, as PFL can be (de-)activated by the “SET_PRELISTEN_ON” or “SET_PRELISTEN_OFF” telegrams only.

If an input module is removed during operation, a previously selected channel will automatically be deselected.

All source selections are lost after power-off.

Input Routing With “SET_SAS_INPUTROUTING* FaderNr”, the CAB can control the

input selector of a channel.

Using “SET_SAS_INPUTROUTING* FaderNr” does not deselect a previously selected source.

Date printed: 05.10.99 Automation E10/5

On-Air 2000 Digital Mixing System

10.3.3 Communication time-out

Every 10 seconds, the On-Air 2000 sends “GET_DEVSTATUS” to the CAB. If after 30 seconds no valid telegram is received from the CAB, the On-Air 2000 assumpes that the communication is interrupted.

In this case it stops sending telegrams as “FADERSTATUS” to the CAB, and the following actions are performed:

• All channels are deselected (refer to section 10.3.2);

• Source labels are re-drawn (name of selected input source will be indicated again) which might have been overwritten (refer to section 10.3.10);

• A warning: “WARNG: XYZ - BCA - Communication lost” is displayed.

After the next/first telegram from CAB, communication will be re-established. The information: “INFRM: XYZ - BCA - Communication established” is generated.

The On-Air 2000 reports to a “GET_DEVSTATUS” request from the CAB with “DEVSTATUS NO_ERROR”. No error codes are defined.

10.3.4 Output selection

Using the “SET_ZI*FaderNr” telegram, the CAB is able to control the output assignment (program/record bus) of the currently selected input of any channel. This allows to route speech to the program output, and music to the record output.

10.3.5 Start a new title from schedule

In automatic mode, the CAB can start a new title automatically. It is also possible to start new titles manually. In this case the operator opens the fader (while the channel is already switched ON) or switches the desired channel ON (while the fader is already open).

Automatic new title start: The CAB can control the console automatically. This automatic mode must

be activated from within the CAB and can, for example, be used for controlling a program during the night without any assistance. If the CAB runs in automatic mode, it starts playback of the source and sends the “SET_FADER_LEVEL*FaderNr” telegram with the desired level and fade-in time. This will send a new audio level to the DSP, and switch the channel ON in any case. If a take ends, the CAB sends the “SET_FADER_LEVEL*FaderNr” telegram again, with a level of less than –70dB, and with the desired fade-out time. This will send a new audio level to the DSP, and switch the channel OFF in any case.

E10/6 Automation Date printed: 05.10.99

On-Air 2000 Digital Mixing Console

If the CAB changes the audio level, the channel changes into auto take-over mode. This means that the audio level (i.e. actual DSP level) and the fader

level (i.e. physical position of the fader knob) differ for more than a specified auto take-over window. If the fader is moved now, nothing will change until the physical position of the fader knob is within the auto take-over window. Then the auto take-over mode is left. Auto take-over mode is indicated on the touch screen. The operator can recognize the direction and distance to move the fader in order to leave auto take-over mode.

The large arrow at the bottom (or top) indicates the direction the fader has to be moved to leave auto take-over mode. The small horizontal line indicates the current physical fader position. It follows the fader position when the fader knob is moved towards the two small arrows at the left and right margin which indicate the current audio level.

Manual new title start: (Start a new title from schedule manually by DJ)

The “FADERSTATUS*FaderNr” telegram is send to the CAB to start the next title from the schedule. It is used in the same way as the fader start output signal in fader start mode “ON&FADER”. This means, the channel must be ON and the fader must be open. “Fader open” is determined by audio level (actual DSP volume) but not the physical fader position.

Example: Assuming that a channel is playing audio from CAB (audio level “open”)

and the fader is closed (fader level “closed”). This is the case after the CAB has sent the telegram “SET_FADER_LEVEL* FaderNr”, i.e. auto takeover mode. If the operator now takes control of that channel by opening the fader in order to leave auto take-over mode, the On-Air 2000 does not send any “FADERSTATUS*FaderNr” telegram, as the audio level does not change until auto take-over mode is left.

From the user's view, there exist two different methods to start new titles manually:

• Fader A-B operation, and

• Fixed source/channel assignment. The On-Air 2000 supports both methods, as in practice, you will find a mixture of them. The selected method depends on the CAB, whether it uses the input routing facility of the On-Air 2000 for real Fader A-B operation.

Date printed: 05.10.99 Automation E10/7

On-Air 2000 Digital Mixing System

Fader A-B operation: In real A-B operation the operator does not care which fader to open to start

the next scheduled title. No matter which fader will be opened, the next title is played from schedule. In this case, the CAB system uses the “SET_SAS_INPUTROUTING *FaderNr” command to change input routing before playback.

Fixed source/channel assignment: The next title is assigned to a channel by the “SELECT_SOURCE” com-

mand (refer to section 10.3.2). READY and NEXT indication is provided within the channel strip. If more than one channel is ready, the fader of the one indicated as next must be opened. Otherwise, one or more titles would be skipped in schedule.

10.3.6 Next Indication

The CAB is able to indicate on which channel the next title from schedule will be played (“SET_NEXT _BUTTON-LIGHT*FaderNr”). For that channel, the source label will be highlighted, as it is done with the NEXT function. In addition, the source selector field on the channel screen indicates “NEXT” – but only if the channel is selected by CAB (SOURCE_SELECTION). So the selection of an other input is inhibited (refer to the figure above). This way, it is easy for the user to find the next fader to be opened, particularly if the source/fader assignment is fixed (see section 10.3.5).

Only one channel can be the next (“the last wins”).

10.3.7 Indication of the currently playing input line

As the On-Air 2000 is not equipped with motor faders, a clear indication of the channel currently “playing” is necessary.

Under the following conditions the selector field on the channel page indicates “ON-AIR” (refer to the figure above), and the selection of an other input is inhibited:

• Fader (audio level) is open;

• The channel is switched ON;

• The channel is assigned to program and/or record bus (as defined in the Common Settings page);

• The channel is selected by the CAB (SOURCE_SELECTION).

E10/8 Automation Date printed: 05.10.99

10.3.8 Ready indication

10.3.9 AUX mode

On-Air 2000 Digital Mixing Console

The CAB communicates to the console which input lines are ready for playback (SET_FADER _START*FaderNr). In this case, LED 3 of the corresponding channel (OFF LED) will be illuminated, the same way as it is done for READY input signals coming from the corresponding input module. Together with Siemens CARAT, the “SET_FADER_READY* FaderNr.” or “RESET_FADER_READY*FaderNr.” telegrams are used to indicate the status of an input. If the CAB releases a fader (“SET_FADER_READY*FaderNr.”), the console indicates READY by illuminating LED 3. If the CAB blocks a fader (“RESET_FADER_READY*FaderNr.”), LED 3 is switched off.

The CAB is able to switch AUX1 and AUX2 ON/OFF, as well as to control the AF/PF mode (“SET_FADER_AUX_MODE*FaderNr”).

10.3.10 Text display

The console can display two lines of text (12 characters each) in the source label, if the channel is selected by the CAB system (SOURCE_SELECTION). After power-on, the On-Air 2000 displays the input name of the selected source until the first “SET_FADER_DISPLAY_2” telegram is received from the CAB, which will overwrite the source label.

10.3.11 Input gain control

With “SET_FADER_INPUT_GAIN* FaderNr”, the CAB is able to control the input gain of all inputs.

10.3.12 Pre-listening

Pre-listening can be activated either from the CAB or from the console (by pressing the PFL button of a channel ready for playback); refer to section

10.3.8 .

When pressing PFL button of a channel which has previously been selected by the CAB, the console sends to the CAB the telegram “SET_PRELISTEN_ON*FaderNr”. The CAB returns the “SET_PRELISTEN_ON*FaderNr” telegram to the console and starts playback of the corresponding channel to one of its outputs, which is connected to either a normal line input or to the external PFL input of the console. While sending “SET_PRELISTEN_ON*FaderNr” telegram, the CAB can control the PFL function of a channel or of the Extern PFL input.

On-Air 2000 Digital Mixing System

10.3.13 Billing

The On-Air 2000 console reports the status of each input line (“SOURCE_STATUS*Name”), if enabled (“SET_PROTOCOL”). This allows the CAB to generate a list containing information for program settlement.

SOURCE_STATUS*Name Conditions

If billing is activated (“SET_PROTOCOL”), the console reports the “SOURCE_STATUS” of all the channels selected by the broadcast automation system (“SOURCE_SELECTION”).

10.3.14 Time synchronisation

The CAB is able to set the console's internal clock (time and date) if configured so in the Time & Date Format page (watch synchronization); refer to

sectionx12.2.5.

11 USER MODES

11.1 Purpose of user modes

The console is used in different studios with different working practices and different personnel structures. A large part of users in broadcast studios is not technically oriented. A mixing console meeting their requirements must be simple to use, reliable and free of “unnecessary” controls and displays. Setting of a wider range of console parameters, saving of console settings (snapshots), and modifications of the console configuration have to be left for technically more competent users (studio technicians, chief engineer). It is also necessary to protect parts of system data and give the permission to change them only to a restricted number of users. In order to satisfy these needs, the On-Air 2000 console supports individual user access rights.

Three classes of users are defined for the On-Air 2000; these are:

Default user: • No password required;

• Private snapshots;

• Function access rights according to the configuration.

On-Air 2000 Digital Mixing Console

• Defines access rights for the default user;

• Stores private snapshots for all (i.e. default and normal) users.

11.3 User administration

The described access permissions allow different functionality ranges to important console functions for each user. By assigning an appropriate access permission to each user, it is possible to fit the On-Air 2000 console to very different working environments. This user administration is done with the help of a User Administration table that is part of the console configuration. This table can be edited by the Administrator only. The users supposed to use the console with basic functionality do not need an account. To adjust the console to differently trained staff, it is possible to change the access permissions of the default user. A user who wants to store his own, private data (snapshots/mic settings) must have an account containing his name, his access permission table and an optional password.

The USER ADMINISTRATION page can only be opened by the administrator, by touching USER ADMIN in the Mixer Setup page. ten users will be listed. With the USER 22..20 key, the administrator can list the remaining users. When the second block of users is displayed, the USER 22..20 key changes to USER 2..20.

E11/4 User modes Date printed: 05.10.99

11.4 Administration functions

By the administrator, a user record can be created (NEW), changed (EDIT), or deleted (DELETE).

Create user record: To create a new user record, touch NEW. The NEW USER page appears

with empty input fields:

On-Air 2000 Digital Mixing Console

The USER NAME and PASSWORD fields are filled in, using the KEYBOARD page. The maximum length of the password is 22 characters. The user name may exist of up to 20 characters. If the new user is not accepted (e.g. because the user name already exists), an error message tells the administrator that the new user will not be registered. A name can be entered without a password, too.

Access permission is configured by touching the corresponding function keys on the NEW USER page. With SET LIKE DEFAULT USER, the access permission setting of the default user is copied to the user currently being edited and can subsequently be edited again. The new user record is stored with SAVE.

Two users are already predefined: the default user and the administrator; the can only be edited but not created or deleted.

Change user record: A user record is selected by touching the appropriate name key, followed by

EDIT. The USER EDIT page, containing the user's individual data, appears. The data can be edited in the same way as described above, except that the user name is displayed but cannot be modified. The only way to rename a user while preserving his snapshots and mic settings is to save them to a PC-card, delete the user, create a new one with the desired name, and then reload the snapshots and mic settings from the card. After pressing SAVE the old record is replaced by the new one. This procedure has to be performed this way in order to avoid name conflicts in the console's memory and on the PC-card.

When editing the default user, the USER EDIT page looks similar except that no password field and key are displayed. When editing the administrator, the USER EDIT page neither displays the access permission keys nor the USER NAME field and key, but the password field and key is enabled.

Date printed: 05.10.99 User modes E11/5

On-Air 2000 Digital Mixing System

Delete user record: To delete a user record from the user administration table a record must be

selected by touching the desired name key. A dialog box appears; if deleting the user is confirmed there, the selected user is definitively removed from the memory, and the user record disappears from the USER ADMINISTRATION page.

11.5 Log-in procedure and defaults

The console always starts up in default mode. If the user is a registered user, and if he wants to work in his own environment, he must log-in. He has to touch the LOGIN button on the Mixer Setup page. The LOGIN page will appear where the user can touch the button with his own name.

The system checks whether a password is defined for this user. If this is the case, he has to enter his password on the Keyboard page. If the password is correct, the system automatically returns to the page on which the user pressed the LOGIN button. If the password is not valid, a dialogbox will appear on the Login page telling the user that the password was not correct. The user can leave the Login page via the EXIT button which brings him back to the Mixer Setup page.

If no password is defined for a user, the system does not show the keyboard page after a touch on a name field in the Login page. The system directly jumps back to the page where the LOGIN button was touched. As the system does not check for a password in this case, any other user can access a user’s private data which are not password-protected.

If a console is operated by one person only, the Administrator simply has to enable all access rights for the default user. This is the way the user can control all console functions (except the administration functions) without having to log-in.

A default user is always defined in the User administration table. His name is DEFAULT USER. The access permissions of this user can be edited, but the record cannot be deleted, and no login code can be defined for this user.

12 CONFIGURATION

On-Air 2000 Digital Mixing Console

In order to meet the requirements for different studio environments, the OnAir 2000 is highly configurable. Depending on the connected audio equipment, different input and output modules must be installed. Some optional modules (Time Sync, RS232/422, Clock Sync, etc.) can also be installed to allow for extended functionality. All these hardware modules are automatically detected by the On-Air 2000 software. According to the installed hardware modules, the system offers corresponding software configuration options. This software configuration is described in this chapter. A configuration is “static”, which means that it cannot be changed during normal operation. Although snapshots rely on a certain configuration, the configuration data are not stored together with the snapshots. Therefore, snapshots can not change the console configuration.

12.1 Configuration handling

At system startup, each installed module is identified. The list of detected modules is compared with the list of modules which had been installed at the last power-down. If a hardware configuration change is found, a message is displayed in the central screen. This is very important, since e.g. snapshots may not be compatible if the type of an input module has changed.

Hardware configuration can only be changed if the console is switched off.

Modules must not be replaced or added while the console is running; “hot-patching” of modules will make the system hang.

Software configuration can be changed by the administrator, or by any user with access right to the SYSTEM CONFIG. page. Software configuration includes data for:

• Channel labels

• Control signal modes

• Nominal input levels

• Level meter assignment, etc.

An On-Air 2000 configuration can be stored on a PC-card, or loaded from the PC-card into the console.

12.2 Configuration procedure

Configuration of a console can be changed in the SYSTEM CONFIG. page. The SYSTEM CONFIG. page can be reached from the Mixer Set-up page by an operator with an administrator permission.

The configuration parameters are subdivided in groups. Each group can be edited on a separate page accessed from this page.

12.2.1 Input

There are three slightly different INPUT CONFIG. pages for editing input configurations depending on the type of input module identified by the hardware. The pages for microphone, analog line, and digital line input types are shown below.

Microphone input

Analog line input

Digital line input

Channel and input are selected with the CHANNEL and INPUT forward (>>) and backward (<<) buttons. Channel and input can also be selected by touching the Label field of a channel. The display will show the current configuration data for the selected input and channel. For changing a parameter the corresponding button must be pressed; it will change to the next possible value. Consecutive pressing toggles through the available options. Exceptions from this rule are the LABEL, LEVEL, and HEADROOM fields. Pressing the LABEL button will open the KEYBOARD page where an input label can be edited; the values in the LEVEL and HEADROOM fields (analog line inputs only) can be adjusted with the rotary encoders next to these fields.

E12/4 Configuration Date printed: 05.10.99

On-Air 2000 Digital Mixing Console

LABEL: The LABEL field is used for giving a name to a channel. Touching this

field, the keyboard screen opens.

The source label field on the channel screen can display long labels (up to 12 characters), while the input selector fields can display only short labels (up to 6 characters). The following rules apply to the display of the labels in the buttons: The upper line contains the first word plus every following word which completely fits into the field. If the first word is longer than 6 or 12 characters, it is cut after 6 or 12 characters. The lower line is filled up with as many characters (6 or 12) as possible, i.e. the last word is cut if it does not fit completely into the button. The separation character is the space character. If the label consists of one long word only, it is cut after 6 or 12 characters and displayed on one single line. The following table illustrates the different possibilities:

SIGN. / TB SOURCE: Starting with software version V3.0, talkback and signaling can be config-

ured individually. In earlier versions, these settings were allowed for microphone inputs only (there, this function was called “MIC LOCATION”). SIGN. is used for signaling (red light) and monitoring (cut and dim), the available options are NONE, CR, and STUDIO. The TB SOURCE parameter in the INPUT CONFIG. page sets the assignment of the input to the TB bus (NONE, from CR, or from STUDIO).

During talkback from the studio, the studio speakers are dimmed only if at least one input is configured as SIGN. = STUDIO and TB SOURCE = STUDIO. The same applies for talkback from the control room.

INPUT CONNECTOR: (Digital input modules only)

Each (A and B) input of a digital input module has three different input connectors (XLR, RCA/Cinch, and optical/TOSLINK). This option selects which connector is used for the A and the B inputs independently.

LEVEL: (Analog line input modules only)

“Level” is the nominal studio level expressed in dBu.

HEADROOM: (Analog line input modules only)

“Headroom” is the difference between the A/D converter's clipping level and the nominal studio level. Example: An input with a level setting of +6 dBu and a headroom setting of 9 dB will accept a +15 dBu signal before the A/D converter comes into overload.

CTRL. OUT 1/2: Please refer to section 9 for more information on this subject.

CTRL. IN: Please refer to section 9 for more information on this subject.

TO N–1 A/B, TO AUDIT: By setting these fields to ON, the input signal is routed to the corresponding

N–1 (A and/or B) or audition bus. The audition bus is similar to the N–1 busses, but it is a stereo bus which can be selected as a monitoring source in the control room. Talkback to the audition bus is possible only on the analog outputs of the optional monitoring extension. Configuration for N–1A, N–1B, or AUDIT:

TIMER START: If TIMER START is set to YES, the fader stop watch will be started/reset

by the corresponding fader, if the channel is ON and the fader is opened.

SAVE / EXIT: The Input Configuration must be saved for each channel. If the user

switches to a different channel, a dialog box will call her/his attention to the fact that the changes will be cancelled if she/he does not save the current Input Configuration. The program remains in the Input Configuration page when saving a channel. Changes which have been saved once will not be cancelled when leaving the Input configuration page with EXIT.

12.2.2 Common settings

The COMMON SETTINGS page contains the following configuration possibilities:

CR DIM WHEN AUDITION SEL: When the Audition bus is selected as a CR monitoring source, and a CR micro-

phone channel is ON, the CR monitor speaker level will be attenuated (DIM), muted (CUT), or nothing happens at all (DON'T CARE).

PFL CUT ON CH. ACTIVE: If YES is selected, the signal of a channel is taken off the PFL bus when the

channel is ON, although the PFL function is active (the PFL function remains active).

ON AIR INDICATION: Three possibilities are available: ΣPROGRAM, ΣRECORD, or ΣPROG-

RAM AND ΣRECORD. The ON-AIR signaling is only active if at least one channel is ON, if this channel's fader is open, and if this channel is assigned to the selected bus (ΣPROGRAM, ΣRECORD, or either of them). In conjunction with automation, ON-AIR is indicated in the input selection field of the channel selected by the automation system. FADERSTATUS is ON-AIR if the input is assigned to the selected bus (ΣPROGRAM, ΣRECORD, or either of them). SOURCE_STATUS is ON or ON-AIR, respectively, if the input is assigned to the selected bus (ΣPROGRAM, ΣRECORD, or either of them).

KEY FUNCTIONS: Functions of the channel keys labeled ON and OFF.

The ON key either switches the channel ON or has an ON/OFF toggle function, depending on the function selected for the OFF key.

Date printed: 05.10.99 Configuration E12/7

If the OFF function is selected for the OFF key, the channel is switched off by pressing this key; if LOCATE is selected, the ON key function automatically changes to a channel ON/OFF toggle function (also refer to sections

9.2 and 9.3).

12.2.5 Time & date

On-Air 2000 Digital Mixing Console

The watch gives a permanent time, day of week, and date display. The normal time reference is an internal battery-buffered real-time clock (RTC). The RTC continues to run even when the console is switched off. Therefore it is unnecessary to set the watch at power-up. The RTC can also by synchronized by an optional TimeSync Module connected to the control module bus, or to the automation input using an RS232C line. If the synchronization is established, the top right corner of the central screen shows an “S” (sync OK). Changes to the time or date settings are made on the TIME page. Access permission to the SYSTEM CONFIG. page is required. From the HOME page, this page is found by selecting MIXER SET-UP, followed by SYSTEM CONFIG., TIME & DATE, and TIME.

An example of the TIME page is given below.

The hours, minutes, and seconds are adjusted with three of the rotary encoders. By touching the “SAVE” button, the parameters are updated. If they are invalid, the parameter changes are ignored.

The DATE page is shown below. This page is displayed by touching the “DATE” button on either the TIME or the FORMAT page.

The day of the week, month, and year is adjusted with three of the rotary encoders. By touching the “SAVE” button, the parameters are updated. If they are invalid, the parameter changes are ignored.

The watch configuration is done in the TIME & DATE FORMAT page. This page is displayed after touching the “FORMAT” button on either the TIME or the DATE page.

12.2.8 Console dump

On-Air 2000 Digital Mixing Console

More information on this subject can be found in section 13.

A “console dump” consists of configuration data (CONFIG. DATA), snapshots (global and private), and mic settings (global and private).

The CONSOLE DUMP page allows the user to store mixer set-up data on a PC-Card, to send them to the serial port, or to load mixer set-up data from a PC-Card. This feature can be used for back-up purposes, for copying data from one console to another, or for diagnostics. A PC-Card can contain one console dump only. It is possible to dump or to load the mixer set-up data completeley or partially only. The selection is done with the CONFIG. DATA, GLOBAL and PRIVATE SNAPSHOTS, GLOBAL and PRIVATE MIC SETTINGS buttons. The function can then be selected with the buttons in the center of the page and is executed by touching the EXECUTE button. Before dumping any data, the PC-Card has to be formatted. This can be done in the lower one of the two slots (slot 0). Touch FORMAT followed by EXECUTE. A dialog box appears where the user can confirm the formatting (i.e. erasing the card completely). While formatting, the FORMAT button flashes. When loading data from the PC-Card, the console data will be overwritten. Therefore this procedure has to be confirmed in a dialog box. The EXIT button returns to the SYSTEM CONFIG. page.

A configuration is loaded into the console by selecting CONFIG. DATA, LOAD FROM

PC-CARD, and EXECUTE. An error message is displayed if the configuration cannot be loaded completely (e.g. Channel Type Mismatch).

Snapshots are loaded into the console by selecting GLOBAL (or PRIVATE) SNAP-

SHOTS, LOAD FROM PC-CARD, and EXECUTE. Snapshots existing in the console will be overwritten.

Microphone settings are loaded into the console by selecting GLOBAL (or PRIVATE) MIC

SETTINGS, LOAD FROM PC-CARD, and EXECUTE. Mic settings already existing in the console will be overwritten.

12.2.9 System synchronization

On this page the system synchronization is configured. The sychronization source can be internal or external; for an external source the sync signal type must be defined.

All possible sync modes are listed below. If the optional clock sync module is not installed, only INTERNAL can be selected.

Sync source Sampling rate

INTERNAL 48 kHz 48 kHz ±100 ppm default, or

48 kHz, precision adjustable on sync module (if

installed); adjustment range approx. ±1000 ppm

WORDCLOCK 32/44.1/48 kHz 32/44.1/48 kHz

AES/EBU 32/44.1/48 kHz 32/44.1/48 kHz VIDEO 25 FRM/S 48 kHz 48 kHz VIDEO 30 FRM/S 48 kHz 48 kHz

VIDEO 29.97 FRM/S 47.952 kHz 47.952... kHz

VIDEO 29.97 FRM/S 48 kHz 48 kHz

Note: The On-Air 2000 is designed to run at a sampling rate of 48 kHz. Due to

this fact, filter parameters are accurate at 48 kHz only. If the console is synchronized to 44.1 kHz, the actual center and takeover frequencies of the EQ are lower by 8.125 %; if the clock frequency is 32 kHz, the frequencies will be lower by approx. 33.3 %.

If the console is synchronized to an external signal, a message box is displayed if synchronization is lost; a “Missing External Clock” warning is added to the error list. If the console was synchronized to either WORDCLOCK or AES/EBU and a “no sync” condition is detected, the console automatically selects the INTERNAL mode; however, the external clock selection in the SYSTEM SYNC page is not changed. As soon as a valid external clock signal is available, the console will be re-synchronized. If synchronization to a video source is lost, only a message box is displayed. The sync source remains in VIDEO mode.

If the Clock Sync module is removed, sync source selection changes to INTERNAL mode, and no other sync source can be selected.
