Introduction

INTRODUCTION

The MAGIC ISDN Telephone Hybrid system enables the forwarding of telephone calls to analogue or optional AES/EBU Audi o interfaces. Since the sys tem is based on a modular construction, it is possible to expand it as desired. The basic system supports a simultaneous Hybrid function up to three or four callers, as well as call forwarding to a selected number. With an extension system four additional channels are available, which can be used for additional callers or other call forwarding numbers. Besides, each system has an additional analogue interface. The maximum build supports up to 16 callers simultaneously On Air.

In contrast to previous systems, great emphasis has been put on using as little external wiring as possible. The system is able to realise functions such as digital mixing of callers, digital Mix Minus, Echo Cancelling, AGC, etc.

The configuration and operation of the system is made via the Windows application MAGIC TOUCH, included in the delivery of the Master system. The software is optimised for operation with a Touch screen.

FIG. 2 THE BLOCK DIAGRAM OF THE MAGIC ISDN TELEPHONE HYBRID

2.1 Functionality

The Telephone Hybrid system has a maximum of four MAGIC ISDN Telephone Hybrids, which are connected via the Extension Bus. Therefore a maxi-

mum of 8 S

interfaces as well as 4 analogue Audio inputs and Audio outputs

are available to the user. Additionally, a Handset or MAGIC Hybrid Headset can be connected to the front side of the system.

With the optional AES/EBU/ANALOGUE Module, any part of the system can be extended by two Audio inputs/outputs.

Via the Telephone Hybrid system - depending on the build - up to 16 callers can be put On Air or in Pre Talk simultaneously. Additionally, there are con- figurable call forwarding possibilities.

For each caller, a digital Echo Canceller is available. This echo canceller i s necessary to suppress disturbing echos when the caller is using a normal analogue telephone.

Likewise, the Automatic Gain Control (AGC) can be switched on for each caller.

To suppress disturbing noise from callers who are currently not speaking, the Expander can be activated.

In the conference mode there is the possibility of mixing all callers digitally

Hardware Options

3.3 AES/EBU/ANALOGUE Module

The optional AES/EBU/ANALOG Module extends the system by two further analogue or two digital AES/EBU inputs and outputs (switchable). Via the MAGIC TOUCH software, each Audio interface can be configured as desired to the greatest possible extend.

Therefore, three analogue inputs (Audio interface already existing in the system + two further modules) and three analogue Audio outputs are available when selecting the analogue input Audio interface (see Fig. 5). The two analogue outputs of the modules are, additionally, activated in parallel, on the digital Audio interface of each module.

FIG. 5 AUDIO INTERFACES WHEN SELECTING THE ANALOGUE INPUT

If the digital inputs of the module are selected (see Fig. 6), one analogue and two digital Audio inputs are available as well as two digital and one analogue output. The digital outputs of the module are additionally activated in parallel to the analogue Audio interfaces of the module. The digital input as well as the output have their own sample rate converter. The word clock can be read or fed in via the BNC connector.

Please note that the two inputs/outputs are physically one AES/EBU interface. The outputs are always connected in parallel.

FIG. 6 AUDIO INTERFACES WHEN SELECTING THE DIGITAL INPUT

Subsequent installation of the module can only be made in our factory.

Maximum number of Audio interfaces

The maximum number of available Audio interfaces depends on the number of B channels. The sum of the Audio interfaces and B channels (visible channels + call forwardings) is limited to 24 (e.g. 12 Audio interfaces and 12 B channels). The maximum number of Audio interfaces can be twelve

in the

maximum build (see CHAPTER A3, page 141).

Until release 3.0, a max. of only seven Audio interfaces are available.

Page 23

Hardware Options

3.4 Headset/Handset

The MAGIC ISDN Telephone Hybrid has an Audio connection for a Headset/Handset. Via this headset/handset e.g., the Pre Talk can be carried out.

Switching between the handset and an Audio input of the system is made via the MAGIC TOUCH, MAGIC TOUCH LAN or the MAGIC Hybrid Keypad.

If the handset is used, a separate screener place can be implemented. In this case, the presenter uses his headset for the Pre Talk. The software is implemented in such a way that faulty operation between presenter and screener place is not possible.

The supply line between headset and Hybrid system can be extended up to 20 meters, since the Audio interface is implemented as an electronically balanced interface.

3.5 MAGIC Hybrid Headset

4 SOFTWARE OPTIONS

4.1 MAGIC TOUCH LAN

FIG. 8 USAGE OF THE MAGIC TOUCH & MAGIC TOUCH LAN SOFTWARE

The MAGIC TOUCH LAN software supports independent operation of MA- GIC ISDN T elephone Hybrid systems via the local Ethernet network. The appli-

cation can be used on any PC connected to the LAN. The operation is made via the TCP/IP protocol and accesses to the MAGIC TOUCH software running on the PC that is connected to the ISDN Telephone Hybrid System.

The MAGIC TOUCH LAN software can be used on a maximum of seven places simultaneously. Applications are for example, screening via a separate screening place or the complete operation of the system via a technician.

Page 26

PAGE 26

Software Options

4.2 MAGIC SCREENER

The MAGIC SCREENER database supported, screener software enables a connection between the MAGIC TOUCH control software, the feature rich screening and the adminsitration of all callers. Also, remote control such as dialling or switching of single lines of the ISDN Telephone Hybrid, is possible .

The connection between the MAGIC TOUCH and the MAGIC SCREENER software is established via the LAN with the help of the TCP/IP protocol. The caller data is stored in a central data base to which all applications have access.

In principal, the MAGIC SCREENER can be installed as many times as desired in the local network. Therefore, simultan eous screening of se veral screening places is possible.

FIG. 9 USAGE OF THE MAGIC TOUCH & MAGIC SCREENING SOFTWARE

Page 27

PAGE 27

Software Options

4.3 MAGIC TOUCH ADMIN/ADMIN LAN

The MAGIC TOUCH ADMIN software enables the administration of up to four MAGIC TOUCH LAN clients, who use a common Central Hybrid System.

For each studio, the number of caller lines and Au dio interfaces is assigned via a Preset. Each studio sees, on its MAGIC TOUCH LAN screen, only the lines assigned. An important advantage of this solution is the flexible assignment of a studio: therefore, a particular show can be broadcast from any studio without any major changes to the PABX or of the Audio wiring.

Optionally, MAGIC TOUCH ADMIN LAN software is available, which can be used, e.g. for a common screening of all caller lines.

5 PUTTING THE SYSTEM INTO OPERATION

5.1 Mounting

With its dimensions (W × H × D) of 439 mm × 44,5 mm (1HE) × 300 mm, the MAGIC ISDN Telephone Hybrid System can be operated as a table-top device or can be mounted in 19’’ racks. Additionally, mounting brackets are provided for an ETSI rack.

During the installation, care should be taken to ensure that the bending radius of the cables is always greater than the minimum allowed value.

If the MAGIC ISDN T elephone Hybrid is installed in a rack, it should b e ensured that sufficient ventilation is provided. It is recommended that approx. 3 cm clearance is left next to the openings. As a rule, the ambient temperature of the system should not lie outside the range +5°C to +40°C. These limits are of particular importance if the system is inserted in a rack.

During operation, the humidity must lie between 5% and 85%.

5.2 Connection to the mains supply

The system can be operated with a mains voltage between 90 V and 253 V and a mains frequency between 45 Hz and 65 Hz. The power consumption has a maximum value of approx. 30W. In accordance with safety regulations, the housing must be earthed (grounded). This earthing is normally realised via the protective earth (or ground) conductor of the mains cable. If the mains cable does not have a protective conductor, however, the device must be earthed via its earthing bolt.

After switching the system on, the green POWER LED should light up. An internal reset is then triggered. After approx. 45 seconds, the system is ready for operation, when the red LED ALARM stops blinking.

5.3 Alarm indication LEDs

The MAGIC ISDN Telephone Hybrid has three LEDs for status indication.

Incorrect ambient temperature and humidity can lead to equipment failure.

Operation of the unit outside the above limits invalidates the warranty. The operation of the system must therefore lie within the specified limits.

Dangerous voltage in case of inadequate earthing!

If the earthing is defective or lacking, hazardous voltages can be present on the housing in the event of a fault.

Do not use extension cables without an earthing conductor! In case of doubt provide additional earthing!

5.4 Controls on the front panel

The system has no controls on the front panel; there is only a socket for the Handset or the MAGIC Hybrid Headset (not included in the delivery).

5.5 Changing the fuse

The mains system is protected by a fuse, which is soldered into the syste m. Only qualified personnel are allowed to change the fuse.

Dangerous voltage when the equipment is opened!

The unit should only be repaired by experienced technicians or our expert personnel.

5.6 Cabling of the system

The following figures show with help of examples, the general cabling of the system.

The assignment of the Audio and relay interfaces are only an example. The assignment can be configured in accordance with your personal requirements (see CHAPTER 7.7.3.14, page 98).

You must not forget to connect the included dongle(s) to the Slave system(s), since the basic function of a slave is configured by this. Please pay attention to the numbering of each dongle.

When using a Master system, no dongle has to be connected.

If a combination of Master and Slave system is used, not all available S0 connections need to be connected to the ISDN network. If you are working with a maximum of only 4 B channels, but also want to use the Pre Talk function, you only need to connect 2 S

interfaces to the Master system.

Page 32

PAGE 32

Putting into operation

5.6.1 ... without AES/EBU/ANALOGUE module

In this wiring exemple (Fig. 11, page 32) a Pre Talk, a separate Hold and an On Air Audio interface are used. A fourth Audio interface is also available in the

Slave 3 System for, e.g., an alternative On Air or Pre Talk Line (see CHAPTER 7.7.3.1.2, page 60).

The function of the relays can be programmed as desired (see CHAPTER

7.7.3.15, page 102). Useful is e.g., the use of a relay for incoming calls and for operating the mixer as soon as a line is switched to Pre Talk or On Air.

For redundancy purposes, a MAGIC Hybrid Keypad can be connected in parallel to the Master System. This keypad ensures that if the PC crashes, the caller lines can still be operated.

Operating Modes

6 OPERATING MODES

The MAGIC ISDN Telephone Hybrid system has a very flexib le implementa- tion. Therefore, nearly all kinds of applications can be realised. In the following, the different operating modes/possibilities are displayed. Of course, the displayed operating modes can be mixed. Further possibilities can be found in the description of the software functionalities.

6.1 Default operating mode

In this operating mode, the system is used with its basic functions:

– Operation only via the local Touch screen (e.g. for a presenter who uses all

functions on his own)

– Use of at least two Audio interfaces for Pre Talk and On Air.

– The Pre Talk can be done via the Pre Talk Audio interfaces or via the op-

tional handset.

6.1.1 ... without AES/EBU/ANALOGUE module

FIG. 13 DEFAULT OPERATION WITHOUT AES/EBU/ANALOGUE MODULE

Without the AES/EBU/Analogue module (see Fig. 13) at least two systems are necessary, to ensure that two Audio interfaces are available. Additionally, up to four ISDN S

lines for 8 callers are available.

By installing further MAGIC ISDN Telephone Hybrid Slave systems as well as AES/EBU/Analogue Modules, the system can be upgraded according to requirements.

6.1.2 ... with the AES/EBU/ANALOGUE module

When using the AES/EBU/Analogue Module (see Fig. 14) one system is enough for the Pre Talk and On Air functionality with two ISDN S0 lines for four callers. The free Audio interface can be used, e.g. for a separate Hold signal.

By installing further MAGIC I SDN Telephone Hybrid Slave system(s) as well as AES/EBU/Analogue Modules, the system can be upgraded according to re-

6.2 Multi fader operation with AES/EBU/Analogue module

In this operating mode the callers are not mixed in the system, they are released separately on different Audio lines:

– Usage of at least two alternative On Air Audio interfaces and one Pre Talk

Audios interface. Depending on the system build, a maximum of four separate alternative On Air lines can be installed (see CHAPTER 7.7.3.1.2, page 60).

– The Pre Talk can be done via the Pre Talk Audio interface or via the op-

tional handset.

Operating Modes

6.3 Multi-Pre-Talk with AES/EBU/Analogue module

In this operating mode, a screener place is connected in parallel to the studio via another alternative Pre Talk Audio interface. The Pre Talk of the presenter and the Pre Talk of the screener can be used independently. Depending on the system construction, up to six alternative Pre Talk lines are possible.

The screener can talk to the callers via a normal telephone and with the help of the call forwarding function.

7.5.1 Operation keys

7.5.1.1 PRE TALK SRC (Pre Talk Source)

With the help of the PRE TALK SRC button it can be selected whether the Pre Talk should be done via the optional handset ( key setting) or via the Audio input which is configured as Pre Talk ( key setting) (see CHAPTER 7.7.3.14, page 98).

The Pr e Talk mode is automatically signalled by the Pre Talk Relay (see CHAPTER A4.5, page 146).

7.5.1.2 GLOBAL (Drop All, Lock)

With the help of the (drop all connections) operating key all connections are dropped. Not included in this function are lines defined as VIP lines (see CHAPTER 7.7.3.5, page 76).

If the (Lock) button is active ( key setting), all lines of the system are blocked for incoming calls. Lines defined as VIP lines are excepted (see CHAPTER 7.7.3.5, page 76)

Outgoing calls are possible on any line.

7.5.1.3 Forw. Call (Call forwarding)

The Call Forwarding button enables the selection of two predefined call forwarding destinations. The second call forwarding destination is only for temporary use. This means that after forwarding the first call the call forwarding destination is set again.

The call forwarding destinations are defined in the submenu S

Line → Call

Forwarding

→

1st. telephone number for Call Forwarding and 2nd. telephone number for Call Forwarding (see CHAPTER 7.7.3.4, page 73). The corre- sponding Name of the call forwarding is displayed on the operating key.

The switch over of the Pre Talk Source can also be automated. In this case for example, the presenter must always use the Audio input and the Pre Talk source must always use the Handset (configuration in the LAN

→

Restric-

tions → Pre Talk Source Auto Following submenu (see CHAPTER 7.7.3.13,

page 95))

If the presenter switches the caller into Pre Talk the Pre Talk Relay can be used to switch in a mixer automatically. If the Pre Talk Source is automated (see previous info box) the Pre Talk Relay will also switch in the mixer only if the pre talk source is in pre talk with the caller. In the General

→

Pre Talk relay submenu choose the Pre Talk Signalling combined with Pre Talk Source option to switch in the mixer only if the presenter is in pre talk via the

Audio input. Do not forget to set in the Relay submenu (see CHAPTER

7.7.3.15, page 102) the Audio Line

was not transmitted by the system.

The gender of the caller can be defined using the (unknown), (female) and (male) button .

A caller can be defined as VIP by pressing either the (no VIP) button or the

(VIP) button.

A caller can be blocked by pressing either the (not blocked) button or by pressing the (blocked) button. The duration of the lockage is automatically set for 1 year.

In addition to the entry of Information or of the topic, the mood of the caller can be entered. The following entries are possible: (friendly), (neutral),

(unfriendly).

All entries are accepted and stored by pressing the button.

By pressing all changes and entries are deleted.

7.5.1.4.3 Further possibilities for establishing a connection

(1) If you want to call a person on a certain line, you must only press one

of the (Pre Talk), (Hold) or (On Air) buttons of an available line in the MAGIC TOUCH main panel. Depend ing on t he co nfiguration, either the manual call dialog or the telephone book opens. The configuration of this optional function is made with General

→

Miscel-

laneous Settings

→

Show dial dialog on disconnect (see CHAPTER

7.7.3.1, page 58).

(2) If one line is defined as a VIP line and if for this line, only one VIP is

selected (see CHAPTER 7.7.3.5, page 76), the connection to this VIP is automatically established when either the (Pre Talk), (Hold) or (On Air) button is pressed in the MAGIC TOUCH main panel.

(3) If one line is preset for a call (name is displayed in the information field

even if there is no connection), the connection to the preset caller can be established by pressing either the (Pre Talk), (Hold) or (On Air) button of the line in the MAGIC TOUCH main panel

(4) If there is only one defined information field for all caller lines (see

Fig. 20, page 44) six quick dial keys are available in the MAGIC TOUCH main window for the direct calling.

7.5.1.5 Information

The detailed information area is only available if the display setting is configured accordingly. In General

→

Display Settings the Information for each

caller option (see CHAPTER 7.7.3.1.6, page 66) must not be set. The (Edit)

key enables the displayed caller information (see Fig. 24, page 48) to be changed.

If the Telephone Hybrid is operated via a PABX, the Prefix Numbers (see CHAPTER 7.7.3.4.3, page 75) for internal calls can be suppressed via a minus character (’-’). To suppress the number the prefix number has to be entered including the ’-’ prefix (for example: If the number 130, ’-130’ must be entered).

With the help of the MAGIC SCREENER database software, blocked callers can easily be managed. On one side different blocking periods can be set and on the other side, this blocking period is automatically checked. Therefore after the expiration of the blocking period the lockage is deleted.

MAGIC TOUCH Software

The display of the caller information in this presentation can be automated via

General

→

Display Settings → Show Information automatically (see CHAP-

TER 7.7.3.1.6, page 66). If this option is set, the information on the caller whose mode has just been changed is displayed (e.g. when switching from Pre Talk to Hold) is always displayed.

Via the (Info) button the information of each connected caller can be displayed at any time. Also the display of the name and the telephone number is done with the help of the Info button. To display the name, it must have been previously entered into the telephone book database and the telephone number has to be transmitted from the caller’s end.

If there is no connection on a line, the line can be predefined for a call. Pressing (Info) opens the extended telephone book dialog.

FIG. 25 TELEPHONE BOOK WITH LINE PREPARATION

As in the telephone book dialog a caller can be selected and be predefined for the line using the (SET) button. The (CLEAR) key deletes all presettings. After selecting the caller the name of the caller is displayed in the Info button. The establishment of the connection is done by pressing one of the following buttons (Pre Talk), (Hold) or (On Air).

Additionally, beneath the info button, the temper (friendly), (neutral), (unfriendly), age and gender (male), (female) of the caller are displayed.

The system tries to keep the predefined lines for incoming calls available as long as possible. These lines will be used only when no other line is available. The presettings will not be deleted however.

The entry and the indication of the age is only possible with help of the optional MAGIC SCREENER database software.

Miscellaneous Settings → Press

DROP button 1 second to hang up submenu (see CHAPTER 7.7.3.1,

page 58). Accordingly, the button must be pressed for 1 second before the connection is dropped.

– The (= Call Forwarding) key forwards the caller to one of the call for-

warding targets (see CHAPTER 7.5.1.3, page 45). If the caller has already been forwarded, he can be recalled by pressing . Then the caller is automatically again in the Hold position and is available for all functions. The call forwarding function is only available if it has been activated in S

Line → Call Forwarding → Enable Call Forwarding

(see CHAPTER 7.7.3.4, page 73).

– If the display with only one caller information field is chosen the

(Info) key updates the field. If the display with an information field for each caller is chosen, the information button opens the dialog for entering the caller information (see CHAPTER Fig. 24, page 48). Via the Info button, the caller’s name and telephone number are displayed. It is assumed that the caller has already been entered into the Telephone Book Database and the telephone number has been transmitted from the caller’s end.

7.5.2.3 Level Meter Display

The level meter display (see Fig. 20, page 44) shows the Audio level of the caller between the range of -36 ... +12dBr. The resulting absolute level adjusts the level setting in Audio Level

→

Master and Slave. For example: incoming

level = -15dBr, set Audio Level Out = +6dBu. At this moment it sets an absolute output level of -9dBu. The headroom in the system is always 6dB.

7.5.2.4 Level setting

The Audio signal of the caller can be reduced or increased between the range of -16dB... +16dB. The level setting (see Fig. 20, page 44) can, during an exist- ing connection, either be dragged to the desired position or it can be put to the desired position by clicking. After dropping the connection the level setting is set back to 0dB.

7.5.2.5 Time information

There are two optional timer available to indicate how long a caller has been in the connection mode:

Via the optional MAGIC SCREENER database software, the location of the caller can be displayed instead of the telephone number. The configuration is made in the General

→

Display Settings → Display City instead of telephone

number submenu (see CHAPTER 7.7.3.1.6, page 66).

The level adjustment can only be used if the AGC (Automatic Gain Control) for this line has been turned off (see CHAPTER 7.7.3.11, page 89).

After pressing the OK button all settings are accepted.

The Cancel key deletes all made settings.

FIG. 35 INDEX CARD GENERAL SETTINGS

7.7.3.1.1 Conference Settings

If there is more than one connection, the performance o f the system can be influenced with the help of the conference settings.

The More than one person in PRE TALK option provides the possibility to talk to all callers in the Pre Talk mode simultaneously. The signals of all callers are digitally mixed in the system and the mixed signal is transmitted to the Pre Talk Audio interface. Also, a digital N-1 signal is generated for each caller. If this option is not set, only one caller can be in the Pre Talk mode. If a second caller is put into the Pre Talk mode, the first caller is automatically switched into the Hold mode.

The More than one person in ON AIR option enables a simultaneous On Air conference with all callers who are in the On Air mode. The signals of all callers are digitally mixed in the system and the mixed signal is transmitted to the On Air Audio interface. Also, a digital N-1 signal is generated for each caller. If this option is not set, only one caller can be in the On Air mode. If a second caller is put in the On Air mode the first caller is automatically switched into the Hold mode.

To ensure that one or several callers can be in the Pre Talk mode as well as in the On Air mode, the PRE TALK and ON AIR concurrently option must be active. If this function is not active, several callers can either be in Pre Talk or

Page 60

PAGE 60

MAGIC TOUCH Software

be On Air. If for example, three callers are in the Pre Talk mode and one of them is switched into the On Air mode, then the other two are automatically put into the Hold mode.

The Next-Mode was especially implement ed for game shows. This provides the possibility of putting the callers on Hold immediately without a Pre Talk. By pressing the (Next) button on the MAGIC TOUCH user interface the caller who has been waiting the longest time in the system is automa tically put On Air. By pressing the operating key (Next) once again the next caller is put On Air.

FIG. 36 NEXT MODE

What happens to the previous caller is defined by the After ON AIR state option. Selecting DROP drops the connection, PRE TALK puts the caller in the Pre Talk mode and HOLD puts the caller in the Hold mode. To mark that a caller is already On Air, the Pre Talk and Hold mode are highlighted with a red font.

If the Mix caller in HOLD to PRE TALK output option is active, the signal of the caller in the Hold mode is mixed together with the signal of the caller in the Pre Talk and the common signal is transmitted to the Pre Talk Audio interface. This function is quite useful for recognising that a caller wants to say something but no extra Hold Audio interface was defined (see CHAPTER

7.7.3.14, page 98).

7.7.3.1.2 Alternative Audio Line Mode

So far, only the Pre Talk, perhaps the Hold and the On Air Audio interfaces were used. Additionally all callers On Air or in the Pre Talk mode were automatically mixed in the system. If it is desired to put several callers On Air or to use several Pre Talk Audio interfaces - without mixing them- the alternative Audio Line Mode can be used. Depending on the construction of the system up to four alternative On Air and up to six alternative Pre Talk Audio interfaces are possible.

The release of this operating mode is done by the Enable Configuration of Alt. Audio Lines option. Therefore, at first, there are four alternative Lines available for On Air and Pre Talk for the configuration of the Audio interfaces (s ee

Of course, at any time each caller can be put manually in the On Air mode or into another mode. All functions are available as usual.

NEXT Mode

To select and activate configured alternative On Air Lines on the MAGIC TOUCH user interface the Activate Mode option has additionally to be set. The activation o f alternative Pre Talk Audio interfaces can only be done via MAGIC TOUCH LAN or MAGIC SCREENER applications.

If the Reset Line to Default Audio Line on DROP option is active the line is automatically switched to the default On Air Audio interface after the estab-

lishement of the connection. This does not depend on the selection of the alternative On Air Line. The standard Audio interface is the On Air Audio in-

terface, if defined. Otherwise it is the defined alternative On Air Line with the smallest index (e.g. Alternative On Air Line 1).If the option is not set, the setting of the Audio interface is kept after the connection is dropped.

Normally, the alternative On Air Lines are only used if no conference between callers is desired. However, if several lines with the same alternative

On Air Line are used, a conference between the callers of the same alternative On Air Line can be set up.

For this set the Alternative Audio Lines concurrently option. Therefore with the maximum construction one On Air, four Alternative On Air and one Pre Talk conference can be implemented simultaneously on the MAGIC TOUCH user interface. If this option is not used always only one caller can be on the alternative Line. Callers who have the same index (e.g. alternative Line 1) are automatically put on Hold.

The selection of the alternative Line in use is done by a long pressing (approx. 1-2 seconds) of one of the keys Pre Talk, Hold or On Air or Alternative 1...4 on the MAGIC Touch surface.

When operating with the mouse press the left mouse button. The Preselect the Audio Line dialog for the preselection of the alternative On Air Audio inter- face opens.

FIG. 37 DIALOG TO PRESELECT THE ON AIR AUDIO INTERFACE

Keep in mind that the Pre Talk, Hold and On Air Audio interfaces can still be used if they are configured.

Therefore the maximum build provides a total of twelve

different Audio in-

terfaces for the MAGIC TOUCH user interfaces.

Until release 3.0 a maximum of only seven Audio interfaces are available.

This function also effects the alternative Pre Talk Lines, which can be used by MAGIC TOUCH LAN or by MAGIC SCREENER.

If there is an existing connection, only the button with the active mode can be pressed to avoid an accidental switch over (see Fig. 38, page 62).

If there is no connection, any button can be pressed.

Page 62

By pressing the button the dialog closes without change.

The selection of the desired Audio interface is done by pressing o ne of the following keys

– (Alternative On Air Line 1) – (Alternative On Air Line 2) – (Alternative On Air Line 3) – (Alternative On Air Line 4) – (On Air).

The alternative On Air Line can be selected any time, even during an existing connection.

See Fig. 38 as an example for the use of alternative lines. During the show, two players are playing against each other. They operate the computer game via DTMF tones. To allocate the tones very clearly, both callers are put on separate Audio interfaces. Lines 3 and 4 are already prepared as alternatives to Lines 1 and 2. If a further caller on Line 3 is switched to the alternative Line 1 a conference between line 1 and line 3 would be possible (if Alternative Lines concurrently option has been set).

7.7.3.1.3 Replace Mode

The Replace Mode option was integrated especially for the operation of the Telephone Hybrid system as a command device. For example (see Fig. 39) the high quality image and high quality sound are transmitted via satellite to the studio. The command line is provided to the correspondent via a normal telephone.

FIG. 39 APPLICATION FOR THE REPLACE MODE

To use the advantages o f th e H ybri d syst em th e inc omi ng s ign al of th e sa te llite is fed by the correspondent via an Audio interface, to the Hybrid (Re- placed x). Via the Telephone Hybrid a default connection is established to the correspondent. Now the system replaces the telephone back channel via the Replaced line. The command line (channel to the telephone) will not be changed. It is now possible to have any conference in the studio with several correspondents. Several alternative Lines, as well as the Hold and On Air Lines, can be defined as Audio interfaces to the mixer.

All functions of the Hybrid are available. A correspondent can even be transfered to an optional telephone.

If the Replace Mode

→

Enable configuration of Replaced B channels option is

active the Audio interfaces in Audio Lines

→

Audio Input/Output Interface Assignment (see CHAPTER 7.7.3.14.2, page 99) can be defined as Replace B channel Line 1...12. This option defines which line (B channel) is replaced by

which Audio interface. For a better identification the associated Input is indicated in the index.

Additionally, the MAGIC TOUCH user interface displays a symbol on the particular line (e.g. for input 1) with the relevant Audio input interface (see Fig. 40).

In total a maximum of 12 Replaced Lines and Hold/On Air/Alternative Lines is possible since the system provides within the complete build, a total of

twelve

Audio interfaces. A Pre Talk Audio interface can not be defined be-

cause it does not make any sense considering the operating technique.

Until release 3.0 a maximum of only seven Audio interfaces are available.

7.7.3.1.4 PRE TALK Relay

The Pre Talk mode is automatically signalled via the Pre Talk Relay and can be used to switch a mixer automatically if the programme presenter switches a caller into Pre Talk. When automating the Pre Talk Source (see CHAPTER

7.7.3.13, page 95) the Pre Talk Relay will also switch the mixer, even though only the pre talk source is in Pre Talk via the handset with the caller. With the help of the Pre Talk Relay

→

Pre Talk Signalling combined with Pre Talk Source option the switchover of the mixer is only made if the presenter uses the Pre Talk Audio interface and not the handset.

7.7.3.1.5 Level Meter Settings

The setting of the Level Meter Setting (see Fig. 20) enables to adjust the update interval of the display if PCs with a lower performance are used. If very slow PCs (< 100 MHz) are used, select Seldom; when using PCs between

100...300 MHz set Moderate and for faster PCs > 300 MHz set Often.

The Flicker F ree Drawing of the Level Meter option must only be set, if the

Level Meter Setting flickers a lot on your screen.

7.7.3.1.6 Display Settings

The MAGIC TOUCH user interface permits two different presentations: If the Information for each caller option is not active, only one detailed information

field for all callers (see Fig. 42) is displayed. In this kind of presentation, the display can be automised if the Show Information automatically option is set. Therefore, always, the information on the caller whose mode has been changed (e.g. when switching from Pre Talk to Hold) is shown.

FIG. 42 OPTION "INFORMATION FOR EACH CALLER" NOT SET

If the Information for each caller option is active, an information field for each caller is displayed (see Fig. 43).

The Font Size setting enables the size of the the information field font to be adjusted.

Do not forget to set the Audio Line → PRE TALK assignment, in the Relay submenu (see CHAPTER 7.7.3.15, page 102) at least for one relay, to ensure that a Pre Talk Relay exists.

The font size is individually stored for each setting of the number of visible B channels (Number of B Channels visible) (see CHAPTER 7.7.3.4.1, page 73).

MAGIC TOUCH Software

FIG. 43 "INFORMATION FOR EACH CALLER" OPTION SET

If optional MAGIC SCREENER data base software is availabl e, the location of the caller can be displayed instead of the calling number. To do this, set the x Display City instead of telephone number setting.

With the help of the Default Text for Unknown Caller option, individual text can be entered. This text is then displayed in the Info field of the MAGIC TOUCH user interface, in the case that the number of the caller is not known and no database entry is available.

The system allows a system configuration via Presets. Select the Show Preset

name in title bar option to display in the head bar of the application, which Preset is currently active.

The MAGIC TOUCH user interface was especially developed for a resolution of 1024 x 768 pixels. It is displayed at its best at a 15“ screen. For smaller screens (e.g. 12“) with 800 x 600 pixels, the display of the MAGIC TOUCH screen can be adjusted by activating the Use 800 x 600 resolution (max. 5 B channels) option.

When starting, the software automatically recognises the

Windows screen resolution.

7.7.3.1.7 Time related settings

On the MAGIC TOUCH user interface, two optional timers are available:

– The absolute time display shows the duration of the mode in min-

utes and seconds or only in seconds. The Show Time Symbol option activates it. If the display of the time is in minutes and seconds and not only in seconds, the Display connection time as mm:ss option must be set.

– The relative time display in the form of a time beam shows at first sight,

which caller has been connected the longest time. If a time beam reaches the maximum height, all other time beams automatically scaled down. The configuration of the relative time display is done by activating Show Time Beam (see Fig. 27).

Both time displays can be set back to zero when changing the line mode (e.g. when switching from Hold to On Air). Select the Reset time on Audio Line

Note that the MAGIC SCREENER database so ftware has to be configured accordingly.

With a resolution of 800 x 600 pixels a maximum of five lines can be displayed.

change option for this.

7.7.3.1.8 Miscellaneous Settings

To avoid accidentally dropping a connection by pressing the (Drop) button, it is possible to set the Press DROP button 1 second to hang up option. If this option is selected, the (Drop) button has to be pressed at least for 1 second.

If there is no connection on a caller line the manual dial dialog or telephone book can be opened by pressing one of the keys (Pre Talk), (Hold) or (On Air). Option Show Dial Dialog on disconnect activates this function. Select the according dialling dialog Manual Dialling for manual call or Telephone Book call using telephone book.

7.7.3.1.9 Keypad connected to Hybrid

As redundancy purposes the Hybrid system can be connected to a MAGIC Hybrid Keypad 4/7/12 in parallel to the MAGIC TOUCH software. Therefore,

the operation is assured if the PC fails.

Via Keypad connected to Hybrid, set the keypadthat has been connected. The following settings are possible:

– none: no keypad is connected.

– MAGIC Keypad 4

– MAGIC Keypad 7

– MAGIC Keypad 12

– other: for future extensions.

If the Reset time on Audio Line change option (see CHAPTER 7.7.3.1, page 58) is not set, the time beam is displayed in yellow. Otherwise the time beam is displayed in the colour of the line mode(e.g. red for On Air)

To select Telephone Book the database support must be active (see CHAPTER

7.7.3.3, page 70).

7.7.3.3 Database settings

Function of the database

All MAGIC TOUCH, MAGIC TO UCH LAN and MAGIC SCREENER software modules always use the same Caller.MDB database file (the so called Back End data base) to switch caller data among callers. The file can be installed on any PC on the network. This PC as well as the index where the database file is installed, must be available via the network for all application computers on the network. The second necessary file Screener.MDW admin- istrates the access to the database. This file can be on the same path as well as the database file.

The MAGIC TOUCH, MAGIC TO UCH L AN or MAGIC SCREENER application represents the Front End database. This application enables access to the Back End. The entered path of the MAGIC T OUCH is very important to ensure that during the show, all applications work with the same Back End database file. Both, MAGIC TOUCH LAN and MAGIC SCREENER automati- cally receive the correct path of the currently set Back End database file.

Windows NT4.0/2000/XP

When using Windows NT/2000/XP all necessary files for the use of the database support are part of the operating system. All other Windows operating systems need the database software MS® Access 2000 or the optional MAGIC SCREENER database software which contains a Runtime Version of MS® Access 2000.

To share a folder in the network (Windows XP)

Open the Windows Explorer and then locate the folder you want to share. Right-click the folder, and then click sharing and security. If the Share this folder in the network check box is available, select it. If the Share this folder in the network check box is not available, the PC is

not connected to the network. To install a network, click on the network in- stallation assistant link and follow the instructions to activate file sharing. As soon as the sharing is active, start the procedure again.

To change the name of shared the folder or drive, type a new name in shared name. The new name is what users will see when they connect to this shared folder. The actual name of the folder does not change.

Activate the network user allowed to share files check box to permit other users to access files in the shared folder.

Configuration of the database

FIG. 45 CONFIGURATION OF THE DATABASE ACCESS

The database support is activated by the Data base support option.

After pressing the OK button, the settings are accepted.

The Cancel key deletes the settings.

7.7.3.3.1 Database path

Enter the paths of the necessary database files in Database path.

If the path of the files can be indicated via a letter of a drive (e.g. S:\Program\MAGIC TOUCH\Caller.mdb) set the Allow local path for Data base option.

If this option is not active, the selection of UNC path (Universal Naming Convention) must be set.

In System Database (*.mdw) enter the path of the relevant Screener.MDW file. This file can be stored in the same directory as the Caller Database that has the name Caller.MDB in the in the delivery mode. The name of the Caller.MDB file can be copied and changed

at any time.

When indicating the letter of the drive ensure that all computers of the network use the same letter of the drive for the database index.

An UNC path can be recognised with its two prefixed „\\“. If your database was installed in the network search for the correct path. Best possibility is to use the Browse function and to select network environment. If the MAGIC TOUCH user interface and the database file Caller.MDB were installed on the same computer this procedure must be done.

MAGIC TOUCH Software

The structure of the directory can be browsed via the Browse button.

7.7.3.3.2 MAGIC SCREENER remote control

If it is desired to use the database supported MAGIC SCREENER software in the network, the Enabled option must be first activated.

The provided TCP/IP Port in Network settings has the default setting 8454. Normally a change is not necessary.

The Screening → Incoming call directly on screener telephone option must only be active if the telephone call and the screening are realised via a separate telephone. The caller has to call this telephone directly and for the screening, the optional MAGIC SCREENER screening software must be in use. In this case, the caller data can be entered into the database as usual. If the caller is to be screened, the SCREEN button of the MAGIC SCREENER software must be pressed. Thereby the caller’s information is transmitted to the MAGIC TOUCH software. Afterwards, the screened caller is forwarded to the Hybrid system by a normal call forwarding of the screener telephone. The Hybrid system recognises by the call forwarding number (that means that the screener telephone must tra nsmit its own telephone number) the screene d data record and displays it on the screen. More information can be found in the MAGIC SCREENER documentation.

7.7.3.3.3 Miscellaneous

With the help of the Miscellaneous Settings

→

Automatically clearing of In-

formation on incoming call option, you can select if the info field will either

be deleted (active) automatically if a caller calls again or if the field will be kept (non active).

The file Screener.MDW must not be named.

However, if a port change, keep in mind that it is imperative that all MAGIC SCREENER database applications have to be adjusted accordingly.

Do not mistake this option not with Pre Talk via call forwarding (see CHAPTER 7.7.3.4.2, page 74). For that function the caller can call the Telephone Hybrid directly and is then transmitted through the system to a normal telephone for the Pre Talk. During this action the caller is kept within the Hybrid system.

messages. Excepted are messages such as busy.

7.7.3.4.2 Call Forwarding

A fundamental function of the Hybrid system is the possibility of call forwarding. The call forwarding is implemented in the system. Special PABX protocols are not used for this function. If a call is forwarded, the connection will be established to the call fowarding destination via a pre-d efined B channel (see CHAPTER 7.5.1.3, page 45). In the system, the caller line will be connected internally to the line of the call forwarding target. Therefore, the caller remains in the system. This provides the possibility of returning the caller to the first line. During a call forwarding al least two 2 B channels are used.

Set the Enable Call Forwarding option to activate the call forwarding.

The first channel for the call forwarding is set via First B channel used for Call Forwarding. For call forwarding the last channels of the system are always used.

The numbers of the call forwarding channels are fixed via the Number sub- menu.

The required number of call forw arding channels depends on your application. E.g. for a ’Call-In’ show where the audience is allowed to ask questions, two screening positions are scheduled. These screening positions enter the caller’s data and provide it for the presenter. The screening is made directly by the Telephone Hybrid system (see CHAPTER 6, page 35). Accordingly, at least two call forwarding channels are essential. If the show host forwards the call e.g. to an editor after the talk, a third channel is necessary.

Via the 1st. telephone number for Call Forwarding and 2nd. telephone number for Call Forwarding submenu two call forwarding targets can be established.

The Name that can be entered with each call forwarding is displayed by the Forw. Call key (see CHAPTER 7.5.1.3, page 45) of the MAGIC TOUCH user interface.

The Advanced Call Forwarding mode over separate screener telephone option

Normally this option should be active to avoid an irritatiing the presenter because of error messages. Especially PABXs tend to produce error messages which are not relevant for the operation.

However, when starting the operation these error messages can be quite useful to find the error.

The numbers in brackets show how many B channels can be used.

If the Telephone Hybrid is operated through a PABX, the Prefix Numbers (see CHAPTER 7.7.3.4.3, page 75) can be suppressed for internal calls using a minus sign (’-’). For this function, the PABX telephone number must be entered with a prefix ’-’ (Example: the PABX 130 must be entered as ’-130’).

If no telephone number is entered the manual call dialog or the telephone book are opened automatically (depending on the Miscellaneous Settings (see CHAPTER 7.7.3.1.8, page 68). Therefore, a temporary call forwarding to any destination is possible.

This possibility is quite useful for the second call forwarding destination. To keep this function better in mind enter as name e.g. „manual“.

Page 75

MAGIC TOUCH Software

enables dialling via the Telephone Hybrid system when using a separate screening telephone. Previously, a caller was forwarded e.g. to an editor to provide his address. When using a screening application, where the screener uses either the MAGIC TOUCH LAN or the MAGIC SCREENER software, the screener must be able to forward the caller to his own telephone as well as to establish connections with this telephone. Here the screener will dial via the Hybrid to make sure that the caller is available in the Hybrid system. After setting this option, the call forwarding is displayed by a green arrow instead of a grey one. If a screener wants to call a caller, he must press the call forwarding button. Depending on the configuration, either the telephone book or the manual dial dialog opens. After entering the telephone number and after the establishment of the connection by the (

= call forwarding) button, the screener’s telephone rings first. If the receiver is off-hook, the connection to the desired caller established automatically. Now the caller can be handled as any other caller. If the screening telephone hangs up, the connection is dropped. Pressing the call forwarding button again puts the caller on Hold.

7.7.3.4.3 Prefix Numbers

Via Prefix Nu mbers (outside line) two prefix numbers 1st. external Prefix Number and 2nd. external Prefix Number can be set for the operation of the

Telephone Hybrid system with a PABX. With the prefix number, the PABX offers the possibility of further outside line functions. The Default option defines which of the two prefix numbers will normally be used to establish a connection to an external partner when using the telephone book. For a None- Default-prefix number, a name can be entered. This name will be displayed in the telephone book when using a second prefix number.

The Skip Prefix Number on Incoming Call option should only be set if the PABX prefixes the transmitted telephone number with the prefix number. The telephone number must be displayed in the same way as it is normally printed in the telephone book, that means [national dialling code] [city code] telephone number. Example: within a city: 5271130

within a country: 09115271130 from abroad: 00499115271130

In the manual call dialog (see CHAPTER 7.5.1.4.1, page 46) the prefix number must always be entered.

Page 76

7.7.3.5 VIP Line

The VIP Lines link provides the possibility of keeping one or several lines available for special callers. If a line must always be available e.g. during a game show to make external calls or to enable very important persons to call in, this line must be set as VIP line. This function also helps in the preparation for a show. The participants e.g. of a radio talk-show are previously defined and are assigned as VIP to the relevant line.

FIG. 47 VIP LINE SETTINGS

After pressing the OK button, all settings are accepted.

The Cancel key deletes all settings.

Enter in Number of VIP Lines the desired number of VIP lines. All available lines can be defined as VIP lines. If no VIP line will be used, enter the v alue 0.

According to the defined number of VIP lines, entries are automatically added in the panel below.

If the VIPs are not changed and the VIP lines are displayed without names, all callers defined as VIP in the telephone book can call these lines or you can use these lines to do external calls.

A calling VIP can only be recognised if his/her telephone number is transmitted. Make sure that the transmission of the VIP’s telephone number is active.

Please note that the central connection of the PABX can be occupied very quickly when making ’call in’ actions. Even though the VIP lines are still available, VIP callers normally do not get through as well since they are rejected by the local exchange of the telecom because of the busy lines. In this case, a VIP only gets a connection to the Telephone Hybrid system if he calls the PABX extension directly and not the central number.

Page 77

To link a particualar VIP to a line, select a VIP line and use the Edit button to open the panel for changing a VIP line.

Use the Delete key to cancel a selected entry.

FIG. 48 CHANGE OF A VIP LINE

With the help of VIP search, all callers defined as VIP in the telephone book can be displayed. Select the desired VIP. The selected VIP is displayed as Se- lected VIP with Name and Number.

If the desired VIP is not in the t elephone book, simply enter the name (Name) and telephone number (Number) to define the VIP. Immediately, the entry is marked as VIP in the telephone book (see CHAPTER 7.5.1.4.2, page 47).

After pressing the OK button all settings are accepted.

The Cancel key deletes all settings.

On the MAGIC TOUCH user interface the VIP lines are displayed in violet. If one line was defined for a certain VIP, this caller can be called directly by pressing either the (Pre Talk), (Hold) or (On Air) key.

VIP connections are not dropped by pressing the (drop all callers) operating key (see CHAPTER 7.5.1.2, page 45).

Even if the lock for callers (see CHAPTER 7.5.1.2, page 45) on the Telephone Hybrid system has been activated, all VIP calls remain active.

If the Telephone Hybrid is operated through a PABX, the Prefix Numbers (see CHAPTER 7.7.3.4.3, page 75) can be suppressed for internal calls via a minus character (’-’). For this function the PABX telephone number must be entered with a prefix ’-’ (Example: the PABX 130 must be entered as ’-130’).

After pressing the OK button, all settings are accepted.

The Cancel key deletes all settings.

To activate the Night Mode set the Enabled option.

Callers can either be forwarded by the Route incoming caller selection or they are automatically put on Hold by Auto answer incoming caller to Hold.

When forwarding the call, the forwarding destination must be entered in Telephone Number for Call Forwarding.

Please ensure that call forwarding is

active (see CHAPTER 7.7.3.4.2, page 74).

When selecting automatic call answer, the indication of the Hold Signal Source is additionally essential. Depending on the configuration of the Audio interfaces, a maximum of four different sources are available:

– On Air: the caller hears the Audio signal which is fed to the On Air inter-

face (normally the programme).

– Recorded Hold Signal: the caller hears the Audio signal, max. of 8 seconds,

stored in the system (see CHAPTER 7.7.3.10, page 87).

Page 80

PAGE 80

MAGIC TOUCH Software

– Master/Slave: AES/EBU/Analogue Module Left/Right: the caller hears the

Audio signal that is fed to the corresponding interface.

– Dynamic Hold: the caller hears the Audio signal that is assigned to the line.

This is either the On Air signal or a signal of the Alternative On Air Lines

1...4 (see CHAPTER 7.7.3.1.2, page 60).

If the system has to end the connection of a caller automatically after a certain time, the Automatically hang up after N s option must be active and the desired time must have been entered in seconds.

If the Night Mode is configured, the Night Mode menu is displayed on the menu bar of the MAGIC TOUCH user interface. Via this menu, the Night

Mode is activated and deactivated.

7.7.3.7.1 Redundant system with MSN with block switching

The MSN-2 field is intended for use in a redundant system. For security reasons, many radio stations have a second studi o that i s com ple tely i dent ical t o the first one. In case of fault, calls can be switched immediately to the second studio. In general, the switching to another ISDN nu mber is quite difficult, but the Hybrid offers the possibility of choosing another MSN Block via a TTL control signal.

To activate the redundant system, set the System redundancy option.

For this principal, two Hybrids are operated on the same ISDN Bus. Therefore, without an MSN entry, both Hybrids would signal one caller. To always make sure that only one Hybrid is active, both systems must have a valid number in MSN-1. In MSN-2, enter an invalid number (e.g. 1111111) in both

MSN Usage

An MSN (Multiple Subscriber Numb er) is used for addressing a particular unit on an ISDN Bus. This bus allows the operation of u p to eight units in parallel.

If only one unit is connected, the entry of MSN is normally not necessary.

systems. On both systems connect pin 1 and pin 5 of the USER IO interface as shown in Fig. 54. When switching over, one system now gets the valid MSN-1 block and the other gets the invalid MSN-2 block. Thus, always, only one system is active.

To recognise on the MAGIC TOUCH user interface which MSN is active, the name of the MSN block selected by the system, is displayed in the title bar of the main window. The names of the MSN blocks can be entered in the MSN 1 Name and MSN 2 Name fields.

FIG. 54 REDUNDANT OPERATION VIA MSN-BLOCK SWITCHING

If the system is active the number of lines, as defined in the ISDN configuration, is displayed on the MAGIC TOUCH user interface (see CHAPTER

7.7.3.4, page 73).

If free lines are still available, the inactive system can still be used simultaneously for advanced production. The MAGIC TOUCH user interface displays the relevant lines for the active and inactive systems as per TAB. 5 and TAB. 6. If an odd number of call forwarding channels is used, the active system always gets an additional call forwarding channel.

– On Air: the caller hears the programme in the Hold mode. This setting is

only available if the On Air Audio interface (see CHAPTER 7.7.3.14, page 98) was configured.

– Hold: in the Hold mode the caller hears the signal fed to the Hold interface.

This setting is only available, if the Hold Audio interface (see CHAPTER

7.7.3.14, page 98) was configured.

– Recorded Hold Signal: the caller hears the Audio signal of max. 8 seconds,

stored in the system (see CHAPTER 7.7.3.10.2, page 88).

– Dynamic Hold: the caller hears the Audio signal that is assigned to the line.

This signal is either the On Air signal or an input signal of the Alternative On Air Line 1...4 (see CHAPTER 7.7.3.1.2, page 60). This setting is only available if at least one Alternative On Air Audio interface (see CHAPTER

7.7.3.14, page 98) was configured.

7.7.3.11.1 Line Settings AGC and Echo canceller

All available lines are displayed in the Line settings list. For each line, an AGC (Automatic Gain Control) as well as an Echo Canceller can be turned on or off separately.

Select the desired line and press then the Edit button. Switch the AGC and/or the Echo Canceller ON or off. Turning the Echo canceller on first causes a test signal to be transmitted when establishing the connection (see Info box). Whether or not the Echo canceller will be activated depends on the received Echo and is done automatically.

An echo canceller suppresses the so called line echo. It arises when the caller uses an analogue telephone. When using digital telephones (ISDN or mobile telephone) no line echo can arise. Since the line echo canceller would downgrade the calling signal of digital telephones, it is necessary to check at the beginning of a connection whether or not an analogue or a digital telephone is used. For this purpose a short test signal is transmitted when establishing the connection. On the basis of the received echo, it will be decided wether the line echo canceller will be activated or not.

7.7.3.11.2 Automatic Gain Control Settings

An Automatic Gain Control is only us eful when there is the possibility of making a pre talk with the caller where the correct level can be set.

The setting Threshold defines the level limit from which the signal of the AGC should be "monitored"(useful value: ~ -32 dB). Otherwise, too quiet signals (such as rush) would be increased by the AGC.

To avoid steps in the noise level, the AGC control speed should not be set too high in the Speed of the AGC sett ing. Likewise, it must not be set too low, otherwise the control will never reach the desired target level. The unit for this is dB/ms (useful value: ~ 1 dB/100ms).

The AGC nominal level of the Level setting defines the medium level of the signal, which should be set by the AGC. In the case of a signal without flicker that lies above the threshold value, this level is set after some 100 ms depending on the AGC control speed. When selecting the level it should be seen that this level is not set too high otherwise the hardware related level range is exceededand distortions occur. A level that is set to low affects the understandability of the caller signal (useful value: ~ -18 dB).

The key Default Settings resets the values for the AGC and of the Expander to the default settings.

7.7.3.11.3 Expander

An Expander causes that all signals, which fall below a certain threshold to be completely suppressed. Therefore a rush from the caller side can not be heard anymore during pauses of the caller. The value of the expander threshold, called Threshold (useful value: ~ -32 dB) should always be selected in a way

In the case of satellite connections, where the transmission time of the Audio signal is quite long , the Echo canceller can not work properly. Because of this, it is recommended that the Echo canceller is switched off when there are connections with a long transmission time.

An AGC is no wizard . Callers who are extremely quiet cannot be increased in any way. Very loud callers can not be decreased in any way.

wise a vice versa assignment is made.

When activating the option Screener/Technician disables line for Presenter when switched to PRE TALK, the line for the presenter is blocked as soon as the screener (or technician) puts a caller in the Pre Talk mode. On the pre- senter’s screen, the line will be displayed in grey. Only when the screener has put the caller in the Hold mode the presenter has access to the line again. If the option is deactivated the presenter and the screener have both access to the line.

When activating the Presenter disables line for Screener/Technician when switched to (Alternative) ON AIR option the line is blocked for the screener (or technician), as soon as the presenter puts a caller On Air or on Alt. ON AIR 1 ... 4. Now the line is displayed in grey for the screener/technician. The screener/technician has again access to the line when the presenter puts the caller on Hold. If the option is deactivated the presenter and screener/technician have both access to the line.

If the show host is not supposed to have any Pre Talk functions, the (Pre Talk) button can be masked out by activating the Disable PRE TALK for Pre- senter function.

Likewise, it is possible to mask out the key (On Air) for the screener. For this set the Disable ON AIR for Screener/Technician option.

Via the selection Volume controlled by you are able to define who is allowed to use the gain control (see CHAPTER 7.5.2.4, page 52) for a caller. The Screener and Presenter selection allows gain control by the screener (or technician) and the show host simultaneously. Consequently, the Screener setting gives only the screener the right for the gain control, the Presenter setting gives only the show host the right for this.

The switch over of the Pre Talk source (see CHAPTER 7.5.1.1, page 45) can be automised, e.g. if the presenter uses always the Audio input and if the screening position uses always the handset. For this set the PRE TALK source auto following option. Now, if the show host presses the (Pre Talk) button, the Audio input (setting key) will be used automatically. If the screener (or technician) uses a line in the Pre Talk mode, the Pre Talk source switches over automatically to the handset (key setting ).

7.7.3.14.1 AES/EBU/ANALOGUE Module

When using digital AES/EBU outputs the clock can be defined with Clock source of digital output, which operates this interface. The following settings

are possible:

– Recovered Clock (from digital audio input)

This setting can be used if a digital source is connected to the digital input. The digital output signal is synchronous to the digital input signal.

– Internal Clock

The clock for the output of the digital output signal is generated internally. In this case the sample rate is always 48-kHz.

– External Clock

In this setting the clock that defines the frequency of the output signal must be fed in via the BNC. The sample rate must be 48-kHz.

The corresponding word clock can be accessed as an output via t he BNC con-

nector.

In the panel below the configuration takes place wether the digital or the analogue input will be used. The analogue and the digital outputs are always available in parallel.

The part systems are named with Master, Slave 1, Slave 2 and Slave 3 (see Fig. 12, page 33).

The selection of the analogue or digital input Audio interface takes place by choosing the system (Master, Slave 1, Slave 2 and Slave 3) and by pressing the Edit button. In the selection panel set analogue or digital.

When selecting the analogue input this system provides three analogue inputs (already existing Audio interface of the system + two other interfaces of the module) and three analogue Audio outputs. Both analogue outputs of the module are additionally released in parallel to the digital Audio interface of the module. Set as clock source in Clock source of digital output the operating mode Internal Clock (see page 98).

When selecting the digital

inputs of the module, one analogue and two digital Audio inputs as well as two digital and one analogue outputs are available. The digital outputs of the module are additionally released in parallel to the analogue Audio interfaces of the module. Set as clock source in Clock source of digital output one of the three operating modes described above (see page 98).

7.7.3.14.2 Audio input/output interface assignment

This setting defines the function of each Audio interface of the system.

If the AES/EBU/ANALOGUE Module is not equipped each part system has only one analogue Audio interface. In Assignment 1 the according ON AIR signal of the callers can be found.

In the case you want to use the optional handset on the same interface you are able to select via Assignment 2 the function PRE TALK additionally.

If the optional AES/EBU/ANALOGUE Module (see CHAPTER A4.6, page 147) is equipped the system is extended to two analogue or two digital AES/EBU Audio inputs and outputs. These inputs and ou tputs can be op-

The digital input and output have separate sample rate converters, therefore any digital Audio source can be connected to the input.

Please note that physically this is only one AES/EBU interface.

The assignment of the function is always related to the input and to the output.

Each system module has three relays. One of these relays can be used for the signalling of the Pre Talk mode (see CHAPTER 7.7.3.15, page 102). Connection to the mixer can be made via this relay.

tionally configured to the maxiumum extend possible.

Press the Edit button to select the relevant Audio Interface and define the de- sired Assignment to the interface.

The Default Settings key assigns the most useful default setting to the interfaces.

The Allow multiple assignment of Audio Lines (inputs will be mixed) option enables an assignment to be set multiple times to different physical interfaces. The On Air signal can be output, e.g. to the AES/EBU/ANALOGUE Module

left and AES/EBU/ANALOGUE Module right outputs simultaneously.

FIG. 67 ASSIGNMENT OF THE AUDIO INTERFACE FUNCTION

Depending on the configuration of the systems the following assignments are possible:

– PRE TALK with Handset

– PRE TALK without Handset

– HOLD: feeding of a separate Hold signal. For this, please pay also atten-

tion to the configuration of the Hold signal source (see CHAPTER 7.7.3.10, page 87).

– ON AIR: output of the mixing signal of all callers in the On Air mode. At

the input the programme signal without caller should be feeded.

The optional AES/EBU/ANALOGUE Module can also be attached into the slave system.

A maximum number of twelve

physical Audio interfaces are available in the

maximum build of the system.

Until release 3.0 only maximal seven Audio interfaces are available.

If a function is used several times for different outputs the related input signals are mixed additively. In the above mentioned example On Air, the back signal to the caller is generated out of the input signals of the left and the right channel of the AES/EBU/ANALOGUE Module.

The assignment applies always for the input and the output simultaneously.

This selection is only possible for the analogue default interface of the system

If the Pre Talk function is defined to a digital Audio interface (PRE TALK without Handset), the Handset can only be used if the Audio interface Master/Slave: Analogue Audio for Pre Talk (PRE TALK with Handset) is config-

ured. The system chooses the appropriate Audio interface automatically when selecting the Pre Talk source (see CHAPTER 7.5.1.1, page 45).
