Safety Information
Conforming to this directive will minimise the risk of hearing damage caused by long listening periods. A simple rule to follow is: The longer you listen, the lower the average volume should be. Please take care when working with your audio system – if you are manipulating controls which you don’t understand (which we all do when we are learning), make sure your monitoring level is turned down. Remember that your ears are the most important tool of your trade. Look after them, and they will look after you. Most importantly: Don’t be afraid to experiment to find out how each parameter affects the sound; this will extend your creativity and help you to get the best results.

Installation
B General Installation Instructions
Please consider besides these general instructions also any product-specific instructions in the ‘Installation’ chapter of this manual.
B1 Unpacking
Check the equipment for any transport damage. If the unit is mechanically damaged, if liquids have been spilled or if objects have fallen into the unit, it must not be connected to the AC power outlet, or it must be immediately disconnected by unplugging the power cable. Repair must only be performed by trained personnel in accordance with the applicable regulations.
B2 Installation Site
Install the unit in a place where the following conditions are met:
•The temperature and the relative humidity of the environment must be within the specified limits during operation of the unit. Relevant values are the ones at the air inlets of the unit (refer to Appendix 1).
•Condensation must be avoided. If the unit is installed in a location with large variation of ambient temperature (e.g. in an OB-van), appropriate precautions must be taken before and after operation (refer to Appendix 1).
•Unobstructed air flow is essential for proper operation. Air vents of the unit are a functional part of the design and must not be blocked in any way during operation (e.g. by objects placed upon them, placement of the unit on a soft surface, or installation of the unit within a rack or piece of furniture).
•The unit must not be heated up by external sources of heat radiation (sunlight, spotlights).
B3 Earthing and Power Supply
Earthing of units with mains supply (class I equipment) is performed via the protective earth (PE) conductor integrated in the mains cable. Units with battery operation (< 60 V, class III equipment) must be earthed separately.
Earthing the unit is one of the measures for protection against electrical shock hazard (dangerous body currents). Hazardous voltage may not only be caused by a defective power supply insulation, but may also be introduced by the connected audio or control cables.
If the unit is installed with one or several external connections, its earthing must be provided during operation as well as while the unit is not operated. If the earthing connection can be interrupted, for example, by unplugging the mains plug of an external power supply unit, an additional, permanent earthing connection must be installed using the provided earth terminal.
Avoid ground loops (hum loops) by keeping the loop surface as small as possible (by consequently guiding the earth conductors in a narrow, parallel way), and reduce the noise current flowing through the loop by inserting an additional impedance (common-mode choke).
IV
Installation / EMC
Class I Equipment (Mains Operation)
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 (IEC 320 / C13 or IEC 320 / C19) with respect to the applicable regulations in your country.
BeforeconnectingtheequipmenttotheACpoweroutlet,checkthatthelocal 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 (protection conforming to class I equipment) must be connected to a 3-pole AC power outlet in such a way that the equipment cabinet is connected to the protective earth.
For information on mains cable strain relief, please refer to Appendix 2.

Class III Equipment (Battery Operation up to 60 VDC)
Equipment of this protection class must be earthed using the provided earth terminal if one or more external signals are connected to the unit (see explanation at the beginning of this paragraph).
B4 Electromagnetic Compatibility (EMC)
The unit conforms to the protection requirements relevant to electromagnetic phenomena that are listed in guidelines 89/336/EC and FCC, part 15.
•The electromagnetic interference generated by the unit is limited in such a way that other equipment and systems can be operated normally.
•The unit is adequately protected against electromagnetic interference so that it can operate properly.
The unit has been tested and conforms to the EMC standards of the specified electromagnetic environment, as listed in the following declaration. The limits of these standards ensure protection of the environment and corresponding noise immunity of the equipment with appropriate probability. However, a professional installation and integration within the system are imperative prerequisites for operation without EMC problems.
For this purpose, the following measures must be followed:
•Install the equipment in accordance with the operating instructions. Use the supplied accessories.
•Inthesystemandinthevicinitywheretheequipmentisinstalled,useonly components (systems, equipment) that also fulfill the EMC standards for the given environment.
V
EMC / Maintenance / ESD
•Use a system grounding concept that satisfies the safety requirements
(class I equipment must be connected with a protective ground conductor) and 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 within the corresponding frequency range.
•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. common-mode choke).
•Reduceelectrostaticdischarge(ESD)ofpersonsbyinstallinganappropriate floor covering (e.g. a carpet with permanent electrostatic filaments) and by keeping the relative humidity above 30%. Further measures (e.g. conducting floor) are usually unnecessary and only effective if used together with corresponding personal equipment.
•Whenusingequipmentwithtouch-sensitiveoperatorcontrols,pleasetake care that the surrounding building structure allows for sufficient capacitive coupling of the operator. This coupling can be improved by an additional, conducting surface in the operator’s area, connected to the equipment housing (e.g. metal foil underneath the floor covering, carpet with conductive backing).
C Maintenance
All air vents and openings for operating elements (faders, rotary knobs) must be checked on a regular basis, and cleaned in case of dust accumulation. For cleaning, a soft paint-brush or a vacuum cleaner is recommended.
Cleaning the surfaces of the unit is performed with a soft, dry cloth or a soft brush.
Persistent contamination can be treated with a cloth that is slightly humidified with a mild cleaning solution, such as dishwashing detergent.
For cleaning display windows, commercially available computer/TV screen cleaners are suited. Use only a slightly damp (never wet) cloth.
Never use any solvents for cleaning the exterior of the unit! Liquids must never be sprayed or poured on directly!
For equipment-specific maintenance information please refer to the corresponding chapter in the operating and service manuals.
D Electrostatic Discharge during Maintenance and Repair
Caution: |
Observe the precautions for handling devices sensitive to electrostatic dis- |
|
charge! |
|
Many semiconductor components are sensitive to electrostatic discharge |
|
(ESD). The lifespan of assemblies containing such components can be dras- |
|
tically reduced by improper handling during maintenance and repair. Please |
|
observe the following rules when handling ESD sensitive components: |
•ESD sensitive components should only be stored and transported in the packing material specifically provided for this purpose.
VI
ESD / Repair
•When performing a repair by replacing complete assemblies, the removed assembly must be sent back to the supplier in the same packing material in which the replacement assembly was shipped. If this should not be the case, any claim for a possible refund will be null and void.
•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 wearing a wristlet connected to the ground potential of the repair or service bench by a series resistor. The equipment to be repaired or serviced as well as all tools and electrically semi-conducting work, storage, and floor mats should also be connected to this ground potential.
•TheterminalsofESDsensitivecomponentsmustnotcomeinuncontrolled contact with electrostatically chargeable or metallic surfaces (voltage puncture, discharge shock hazard).
•To prevent the components from undefined transient stress 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.
E Repair
By removing housing parts or shields, energized parts may be exposed. For this reason the following precautions must be observed:
•Maintenance may only be performed by trained personnel in accordance with the applicable regulations.
•TheequipmentmustbeswitchedoffanddisconnectedfromtheACpower outlet before any housing parts are removed.
•Even if the equipment is disconnected from the power outlet, parts with hazardous charges (e.g. capacitors, picture tubes) must not be touched until they have been properly discharged. Do not touch hot components (power semiconductors, heat sinks, etc.) before they have cooled off.
•Ifmaintenanceisperformedonaunitthatisopenedwhilebeingswitched on, no un-insulated circuit components and metallic semiconductor housings must be touched, neither with bare hands nor with un-insulated tools.
Certain components pose additional hazards:
•Explosion hazard from lithium batteries, electrolytic capacitors and power semiconductors (Observe the component’s polarity. Do not short battery terminals. Replace batteries only by the same type).
•Implosion hazard from evacuated display units.
•Radiation hazard from laser units (non-ionizing), picture tubes (ionizing).
•Caustic effect of display units (LCD) and components containing liquid
electrolyte.
Such components should only be handled by trained personnel who are properly protected (e.g. protection glasses, gloves).

Appendix
Appendix 1: Air Temperature and Humidity
General
Normal operation of the unit or system is warranted under the 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.
Undertheseconditionstheunitorsystemstartsandworkswithoutanyproblem. Beyond these specifications, possible problems are described below.
Ambient Temperature
Units and systems by Studer are generally designed for an ambient temperature range (i.e. temperature of the incoming air) of +5 °C to +40 °C. When rack mounting the units, the intended air flow and herewith adequate cooling must be provided. The following facts must be considered:
•The admissible ambient temperature range for operation of the semiconductor components is 0 °C to +70 °C (commercial temperature range for operation).
•The air flow through the installation must provide that the outgoing air is always cooler than 70 °C.
•Average heat increase of the cooling air shall be about 20 K, allowing for an additional maximum 10 K increase at the hot components.
•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 Wrequires an air flow of 0.8 * 2.65 m³/min which corresponds to 2.12 m³/min.
•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 °C to 70 °C.
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 to 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, trouble-free operation cannot be guaranteed, independent of temperature.
Before putting into operation, the system must be checked for internal formation of condensation or ice. Only with a minute formation of ice, direct
X
Appendix
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 one of the outgoing air.
If it is absolutely necessary to operate the cold 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%.
Ensure that the enclosed air is as dry as possible when powering off (i.e. before switching off in winter, aerate the room with cold, dry air, and remove humid objects such 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 a relative humidity of 40% is switched off in the evening. If the temperature falls below +5 °C, the relative humidity will rise to 100% (7 g/m³); dew or ice will be forming.
Example 2: AnOB-vanisheatedupinthemorningwithairof20 °Candarelativehumid- ity of 40%. On all parts being cooler than +5 °C, dew or ice will be forming.

Appendix
Appendix 2: Mains Connector Strain Relief
For anchoring connectors without a mechanical lock (e.g. IEC mains connectors), we recommend the arrangement below:
Procedure: The cable clamp shipped with your unit is auto-adhesive. For mounting please follow the rules below:
•The surface to be adhered to must be clean, dry, and free from grease, oil, or other contaminants. Recommended application temperature range is +20 °C to +40 °C.
•Removetheplasticprotectivebackingfromtherearsideoftheclampand 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.
•For improved stability, the clamp should be fixed with a screw. For this purpose, a self-tapping screw and an M4 bolt and nut are included.
•Placethecableintotheclampasshownintheillustrationaboveandfirmly press down the internal top cover until the cable is fixed.
