Console - Configuring the Mixing Console

For each 52/MX, 52/RX, 52/SX and RM4200D device there is in the project tree a Console subsection under the <Mixer> node. To configure the user interface of the console, select this subsection. There exist three tabs:

On the Keys tab, you can assign logic functions and labels to the keys of the console.
On the Console tab, you can select the needed modules and insert them into the mounting frame.
On the Authorisation tab, you can define for every key, which user group is allowed to use these keys.

To configure the user interface of the console, you first have to select the modules for the console and then assign the desired functions and labels to the keys.

Console Layout Configuration

In the Console subsection in the project tree, select the Console tab to configure the layout of the console.

Follow these steps to configure the layout of a Series 52 device or a RM4200D console:

  1. Select the desired module from the Available Modules area.
  2. Drag the module and drop it in an empty slot (grey rectangle) of the mounting frame in the Console Layout area.

only 52/XC or 52/XS Core: You can change the type of the installation frame in the Type of Console list. You can also change the automatically suggested size of the installation frame in the Size list.

To remove modules from the mounting frame, right-click on the module, select Delete from the contextual menu.

To add a console, in the Console Layout area, right-click on any of the console tabs in the Console View area. Select Add Console from the contextual menu. You can create up to 14 different consoles per DSP frame.

To remove a console, in the Console Layout area, right-click on the console tab you want to remove. Select Remove Console from the contextual menu.

To rename a console, in the Console Layout area, right-click on the console tab you want to rename. Select Rename Console from the contextual menu. A Rename Console window opens. Enter the new console name in New Label box. Click OK.

Keep in mind that splitting the modules to different consoles does not mean splitting of the mixer functions. Independent from the number of consoles, all have access to the same busses and fader signals. The splitting of the mixer into separate consoles is for organisational reasons only. If you want to operate another independent console in a DSP frame, find further information in Virtual Mixers.

Note
The graphical layout of the consoles is only important for printing the mixer view, otherwise it is mainly a visualisation of the mixer for the software users. For the configuration itself, the positions of the modules are not important.

Configuring the console.

To insert a Q-Panel module to the console layout, it is necessary to insert them into a blank console layout. Drag a Q-Panel module to the console layout, the background of the view changes to a Q-Panel mounting frame automatically. It is also not possible to add console modules to a Q-Panel.

Configuring Q-Panels.

If there are already modules in the rack, you can open a contextual menu by right-clicking on the mounting slots.

Contextual menu of the console layout section.

To reorganise the modules in your console layout, use drag & drop, cut and paste or copy and paste. If the modules already have functions and labeled keys, this configuration is transferred to the copy of a module.

In the contextual menu of a module, you find the commands Print module layout and Print key labels. Use them to either print the complete module view including the assigned labels or just the key labels.

In the contextual menu of a module, you find the function Assign physical Module. Use this function to match your console layout to the physical console. This assignment defines which hardware module corresponds to which configured software module. You have to do this assignment for each console module (52/RX, 52/SX, RM4200D) or each module group (52/MX) as well as each TFT display.

Important
Make sure the console is switched on and has network access, before executing this command.

After clicking Assign physical Module, the selected module or a group of modules start flashing in the console layout. At the same time, at least one key flashes on each available module of the physical console and ASSIGN buttons are shown on the TFT displays. Now press a key on the module or the ASSIGN button on the TFT display that you want to match to the software module from where you called the Assign physical Module command. This way, the function is automatically terminated and you have assigned the selected graphical module to the corresponding hardware.

To cancel the Assignment procedure right-click on an module in the console layout and select Cancel physical Module Assignment.

In the contextual menu of a module you can find a Calibrate command.

Use the Calibrate command to adjust the 0 dB fader positions and to appoint the touch sensitive area of TFT displays.

Note
Only the faders of the RM4200D surface can be calibrated. Calibrating faders of a 52/MX mixing desk does not affect the mixer in any way.

Calibrating faders: Set all faders of a fader module to 0 dB (as accurately as possible). Right-click the respective module in the console layout and select Calibrate from the contextual menu. Now, all faders of this module are set to the new value. Repeat this procedure for all other fader modules.

Calibrating TFT displays: Right-click the desired TFT display in the console layout and choose Calibrate in the contextual menu. Now, you can see a cross in one of the physical TFT displays corners. Press this cross as accurately as possible and do the same for the crosses that will appear in the other corners of the display. Repeat this procedure for all other TFT displays.

When inserting the modules in the console view, you have to mind the following:

Important
You have to configure at least two DSP modules, if you want to use 24 or more faders. Beginning from 16 faders, you should use two DSP modules to have sufficient computing power for input and fixed processings available. From 32 faders and more you should use three DSP modules.

Setting up Module Options

In the Module Options area of the Console and the Keys tab, you can adjust the following features for the modules currently selected in the console layout. Keep in mind that Module Options are only shown if no key of the module is selected.

Changing the display content of the fader modules.

The displays of the 52/MX / 52/RX control modules are operated in a split mode. Therefore, the displays can show the values of two functions simultaneously.

The Module-ID of each module is unique in a DHD system and allows the correct communication of the modules among each others. The configurable operating modules of the 52/MX and the RM4200D can be separated into the following functional groups:

Fader Modules and Fader-Overbridge Modules Modules and Control-Overbridge Modules Displays (52/MX only) Q-Panels (52/MX only)
52/MX: IDs #F1 to #F48 RM4200D: IDs #F1 to #F48 52/MX: IDs #C C1T0S0 to #C C14T8S3 (#C CxTySz with 1≤x≤14 (console), 0≤y≤8 (module group) and 0≤z≤3 (position in the module group)) \\RM4200D: IDs #C1 to #C42 Central Displays: IDs #CTFT C1T1 to #CTFT C14T8 (#CTFT CxTy with 1≤x≤14 (console), 0≤y≤8 (module group))

You can insert in an RM4200D console, up to 12 fader modules. In an 52/MX you can insert, up to 48 fader modules. These fader have automatically assigned module IDs. For the RM4200D the IDs are: from left to right #F1 to #F12. For the 52/MX the IDs are: from left to right #F1 to #F48. The fader overbridge modules are an extension of the corresponding fader module, and have the same ID as their fader module.

The control modules have also automatically assigned module IDs after inserting in the console layout. The control overbridge modules are an extension of the corresponding control module and have the same ID as their control module.

You can see the automatically assigned address of a module in the Module ID box.

The selection of the access group for a module defines with which other modules it cooperates for operation and display. All modules of the same access group cooperate, modules with different groups do not. You can choose between four access groups.

Key Configuration

On the Keys tab, you can assign the desired functions and labels to the fader and control modules.

To configure keys of fader and control modules, follow these steps:

Key label with forced line break.
  1. Select the desired module in the console layout. The selected module is now surrounded by a blue border. In the Module area, you see a large view of this module.
  2. In the Module area, click on the key, which you want to configure. Now you can see on the Keys tab, a new Key Options area.
  3. In the Key Options area, enter a label for the key in the Label box. This label is later used as printout for the label key caps. To get a forced line break in the key label, enter a backslash (\).
  4. On the View menu, select Key Functions. The Key Functions window opens.
  5. Select the desired key function and drag it to the key preview in the Key Options area, or to the (No Function) text, or to the desired key in the Module area. According to the selected key function, additional parameters for the configuration of the key may appear in the Key Options area.

The keys on the fader modules can be configured with the key functions for fader modules, independent from the position and layout of the keys. (See Fader Modules)

The keys on the control modules can be configured with the key functions for control modules, independent from the position and layout of the keys. (See Control Modules)

If you have assigned a key function to a key, always a Colors area appears in the Key Options area. Set the logic sources which lead to the lighting conditions of the key.

Depending on the selected key function, you can define here, with which color the key shall light up according to the lamp source. On is the color if the function is enabled, Off if the function is in inactive condition. For the last case, mostly the Off option is used, for example the key does not light up. Depending on the selected key function, you find also different names in the Lamp Source column, for example Standby, Available, Busy, Owned, Layer A, Layer B or the name of the selected lamp source.

For the small keys of the modules, you can define the colors red and yellow. The large keys can light up in red, yellow and green. You can define flashing colors for the keys. Select the check box, in the Colors area.

Note
For the large keys of the modules 52-4220, 52-4250 and 52-4261 yellow is not available as an option. You can use a mixed color instead which corresponds with yellow. This is due to the fact that yellow is not generated by a separate LED but is a mix from red and green. Depending on the tolerance of the components, the key color can differ between the keys.

There are differences in the coloring of the keys - depending on the kind of used components. Certain keys can change the color display by software controlling, others can only be configured using colored key caps. Depending on the key, you can define during configuration, which color the key should have in certain conditions.

52/MX and 52/RX key types

For the 52/MX and 52/RX, at present three different types of keys are used:

type lighting conditions illuminant software-configurable color keyface / travel manufacturer / name
standard, small red LED Yes 12 mm x 12 mm / 4.5 mm eao Lumitas, Series 95
yellow LED
standard, large red LED Yes 18 mm x 18 mm / 4.5 mm eao Lumitas, Series 95

yellow LED yellow, glossy
yellow LED clear, glossy
green LED green, glossy

In addition to the lighting conditions listed in the table, all keys can also be Off.

Please note that the LED color of the standard keys is defined in the Config and can change according to the logic state during operation. Therefore, the key caps have to be clear. As far as the configuration of the standard keys is concerned, the colors refer to LEDs and not to color transparencies.

There is a difference with the keys below the faders of an RM420-020 module. If you select a color for these keys, this is for information only which LED color and color of the key cap is to be inserted during manufacturing the module. These keys can only have the color ordered from DHD. During configuration, the colors refer to the color of the key cap, DHD uses the illuminant according to the table. Further options can not be ordered.

Authorisation - Limiting Access to Keys

On the Authorisation tab, you can assign authorisation groups to certain keys. Use these authorisation groups to deny a user group access to certain keys. You have to create the appropriate authorisation groups previously. (See Administration)

On the Authorisation tab, you see the modules of the console in a minimized view. Keys that have been assigned to an authorisation group are shown red, not assigned keys grey. All grey keys can be used by all console users without entering a PIN.

Console, Authorisation. Assigning keys to authorisation groups.

Important
You can limit access to keys if you have already set up authorisation groups. In addition, on the Console tab, you should have labelled the desired keys. Otherwise, you can not limit access!

To assign a key to authorisation groups, follow these steps:

  1. In the Console Layout area, select a module. In the Module area you can see an enlarged view of that module.
  2. In the Module area, select the key you want to limit access for. A Key Options area appears.
  3. In the Key Options area, you can see a Restrict key access to authorisation groups list with authorisation group check boxes. Select the authorisation groups, which have access to that key. The selected key becomes red and (only on this tab) shows the restricted access.

Important
If you use keys of the console for enabling PIN entry, please make sure that no authorisation group is assigned for these keys, otherwise you can not log in at the console!

Fader Modules

All functions that you can configure for fader modules and fader overbridge modules are described in this subsection.

Note
The configurable key functions for fader modules and control modules are different!

To configure a key, see Configuring keys of fader and control modules.

If you define a function for a key on a fader module, this function is assigned for the same key on all neighbour fader modules of the same type. If you change the function of a key, the appropriate keys of the other fader modules change as well. You can stop this coupled behavior for each key. To do this, select the Independent Key check box in the Key Options area.

You can use the Independent Key option for example for a fader with statically assigned sources or if you want to physically offset a fader module, for example for an independent operator.

Depending on the function you chose for a key, in the Key Options area, additional options are shown.

TFT Views

option or sub-function selection description
Show View Set View • In this list, a fader view is selected that can be configured under TFT Views. By pressing the key, the corresponding view is loaded.
Follow Access • If this function is enabled, the content of the TFT display is overwritten by channel related contents, as soon as the Access key is pressed in a fader strip. • This function makes only sense on control modules. If this function is enabled on a fader module, it is not relevant.
Access View • If a key with the function Access View is configured, it can disable each Show View using Follow Access.
Application examples:
• In a master view a Show View button is configured with the Follow Access function (Button A) and a Show View button without Follow Access (Button B). • If button A is enabled, without the Access function being selected in a channel, the display does not change yet. • Button B is pressed. A new view is shown on the TFT, therefore Button A is not visible any longer, so Button A cannot be disabled. • If the Access key is now pressed in a channel, the view switches to the configured view of Button A. • Press the Access View key to disable the function of Button A and to keep the loaded view of Button B if the Access key is enabled in a channel. Note
This function makes sense if several Show View Buttons are configured in TFT Views using the Follow Access function. Then, you need only one key with the Access View function to disable all Show Views.
Set Channel Views • This function is not working and will be removed in one of the next Toolbox5 versions.
Show Keyboard • Opens a virtual keyboard on a defined TFT display.
To Group • Select from this list, on which TFT group the keyboard should open.
Function • Edit channel label: Use the keyboard to edit the label of a channel.
• Login with keyboard: Instead of using a potentiometer to enter PIN numbers, you can use the keyboard to log in.

TFT Displays

To configure a TFT display, in the project tree, select the subsection <device>/<Mixer>/Console. On the Keys tab, in the Console Layout window click on the desired TFT display. Now you can edit the characteristics of the selected TFT display in the Other Options area.

Control Modules

In general, each key of a control module can be configured with any control module function, independent from its location and built.

Note
The configurable key functions for fader modules and control modules are different!

The flexible construction of the 52/MX and the RM4200D enables you to configure a great variety of functions. Therefore, only a few functions are described here in detail. As a supplement, you can obtain files with example configurations from DHD that you can look at in Toolbox5.

Note
For many functions, you have to configure keys as well in the fader module as in the control module. These functions are marked as ACCESS in the following table. In a fader module, the access key, for example always cooperates with the functions of a control module. This works only if both modules are located in the same access group.

Note
Some of the functions can only be used with control modules that have a display with at least 16 ASCII digits and the appropriate rotary pulse encoder. These functions are marked as DISPLAY in the following table. In addition, some functions may need an OK key to confirm or to reach the lowest menu level. These have the name OK. Please, also mind the access group setting of the used modules.

Important
If the cooperation of several modules is necessary for a function, they have to be located in the same access group. Therefore, when checking for errors, mind the correct assignment of access groups and modules! (See also Setting up Module Options)

To configure a key, see Configuring keys of fader and control modules.

Some functions are ACCESS and DISPLAY functions. In addition, some have more layers that you have access to by pressing a function key again or by pressing OK on the same module. In the table, these are numbered 1. (main level), 2. (2nd level), etc.

• The toggling of the type and filter order is not noiseless!
Delay DELAY - Switches Delay ON/OFF.
DELAY - Delay between 0 s and maximum time, increment 10 ms. The maximum time depends on the selected number of channels of the RM420-424S in the DSP Frame I/O. (see also Delay Sub Module RM420-424S)
• Each full turn of the rotary encoder means a change of 160 ms of the delay time.

The option ON/OFF in a function can also be operated inversely. This means that you either select the desired channel first (ACCESS) and then press the ON/OFF key of a function or press the ON/OFF key of a function first. In the last case, the channels linked to the function indicate this assignment by lighting up the corresponding keys. This is especially useful for dynamic and routing functions.

Examples:

Functions Description

(No Function)

has no function.

User Defined

selection description
• By right-clicking (not assigned) in the Lamp Source column, you can either select the key itself as a source or select any source from the logic sources window.
• You can use the created logic source in many ways, for example for logic functions, output functions, global logic functions or routing to GPOs.
• You can change the sequence of the three rows in the Colors area. Drag a row in the Lamp source column to its new priority place.
• The LED with higher priority lights up if its lamp source is active; two colors can't light up at the same time!
• The LEDs of the keys can also be used to show a condition without having assigned a key function. This is useful to do a test on GPIs.
Momentary • The function is active as long as the key is pressed.
Toggle • The key is stay put.
Timed Toggle • The key is stay put (short press) or spring return (long press).

Monitor Functions

option or subfunction selection description
Monitor Bus • Function for setting up alternating sets of monitor keys.
• Monitor busses are not audio channels on the TDM bus system, but you can set them up internally via special routing functions!
• Monitor keys are assigned to internal selectors. These can be created and edited under Audio/Monitor Functions - Selectors.
• The created selectors can be selected as sources for output functions or for the output routing in the source window Audio under Monitor Functions.
• Selectors can not be used as sources for other DSP functions, for example fixed processing. (To do this, you have to route them via an output function!)
• Summed monitoring is not possible with this function, the keys are alternating. Only one source can be routed at the same time.
• If you press the same key again, the monitor bus changes to the Default Source selected at Audio/Monitor Functions. The condition not assigned is preset (muting the bus). (See also Monitor Functions – Options for Monitoring)
• Sets of monitor keys can also be operated and extended over several modules.
• Monitor bus is useful to save keys.
Selector • You can choose an available selector from this list.
Allow Shift • The selector is shifted if a Monitor Bus Shift key is pressed.
Deny Switch Off • The sources of the monitor bus can only cancel out each other. This way, one of the available monitor signals is always assigned to the monitor bus.
Left Source • Select an audio source from the TDM bus.
Right Source • Select an audio source from the TDM bus.
Monitor Bus Shift • Generally, the Monitor Bus keys influence the selector, that you have assigned to these keys during the key configuration.
• By pressing the Monitor Bus Shift key, a different selector is chosen from the selector list, which now can be controlled by the Monitor Bus keys. The change is not to a defined selector, but the current selection is shifted by a selected value (Shift Offset) to a different selector. This shift is rising with reference to the serial number of the selectors.
• After pressing the Monitor Bus Shift key again, the previous selection in the selector list is enabled again.
Shift Offset • The chosen selectors can be shifted by 0 to 200 entries within the Available Selectors list.
Rotary Selector • After pressing the Rotary Selector key, you can select a source from a selector source list by an encoder.
Selector • Choose a selector, from the selector source list.
Encoder • Select an encoder which selects a source.
Allow Shift • The selector is shifted if a Monitor Bus Shift key is pressed.
Potentiometer • This function enables the operation of the potentiometer functions via key + rotary encoder in control modules.
• Example: Create a software potentiometer and assign it to a bus as Master Level Control (in the project tree <Mixer>/Mixing Functions). Now you can use it to control the level of the bus with an encoder which you can select from the Encoder list (Key Options area)
Potentiometer • Select a software (virtual) potentiometer from the list, to define which potentiometer will be controlled by an encoder. To create an software potentiometer select in the project tree <Device>/Audio. On the Potentiometer tab, create a new software potentiometer and name it distinctively. (See Potentiometers - Assigning Potentiometers)
Encoder • Select an encoder from the list. This encoder controls a software potentiometer, which you can select from the Potentiometer list.
System Functions • Please see the table above for information on system functions.

Auto OffAir • If no channel is routed to the Off-Air bus, the function enables Off-Air bus routing for all channels for which the Auto OffAir function is enabled under <Mixer>/Fader Channels/Fader Logic.
• If Off-Air routings are enabled, and the Auto OffAir key is pressed, the Off-Air routings for all channels are disabled and all channels that have previously been in Off-Air mode are switched off. This is necessary to prevent sending signals of the Off-Air bus accidentally to the program bus when routing channels to a program bus while a fader is open. Note
If no On keys are available in the channels, it is impossible to enable the channels again that have been switched off by the Auto OffAir function.
To prevent this, under <Mixer>/Operation Mode - Off Air Options you can select the “Fader Start On” blocks “Off Air” switch off check box. Using this option, channels can only be switched to the On-Air mode from Off-Air mode if the faders are closed.

TFT Functions

option or subfunction selection description
Show View • Press this key to show a selected TFT view on a selected TFT display.
Set View • In this list, select a TFT view, which will be shown by pressing this key.
To Group • Select a display group from this list, on which the selected TFT view is shown.
Follow Access • The values which are shown in the selected TFT view, belong to the selected (by access key) channel.
• Define a central display on which you show the functions of a channel in full screen mode. To do this, generate a master view that reflects the desired channel characteristics.
Access View • Disables all shown TFT views, which are following an Access key. Example:
• In a TFT master view, a Show View button with Follow Access option is configured (button A) and a second button without Follow Access (button B).
• If button A is enabled without a selected Access key in a channel, the display does not change.
• If button B is pressed, a new view shows up on the TFT display, thus making button A invisible. Therefore, also the function of button A can not be disabled.
• If the Access key is now pressed in a channel, the view switches to the configured view of button A.
• Press the Access View key, the function of button A is disabled and the view loaded by button B is kept if the Access key is enabled in a channel. Note
This function makes sense if you have configured several Show View buttons with the Follow Access option in TFT views. Then, you only need one key with Access View function to disable all Show Views.
Set Channel Views • This function switches the TFT fader views of a selected fader range to a desired view.
Set View • Select the fader view that should be shown.
Physical Fader Range • Choose a range of physical faders for that the fader view should change.
• Set both values to 0 to affect the whole mixer.
Show Keyboard • Opens a virtual keyboard on a defined TFT display.
To Group • Select from this list, on which TFT group the keyboard should open.
Function • Edit channel label: Use the keyboard to edit the label of a channel.

Routing Functions

option or subfunction selection description
• The keys are used for routing the signals of the TDM bus to an output or an output function.
• One key should be reserved for each source and destination.
• Routing can be mono and stereo, this depends on the configuration, but it is similar for all keys! Do not use mixed routing of mono and stereo signals!
• If you press a source key, the correspondent destination keys are lighting up.
• If you press a destination key, you can select a new source. The routing will be done immediately if no Take function is configured. To confirm the routing to the new source, press the Take key.
Input Left Source • Select any source from the Audio sources window for the left channel.
Right Source • Select any source from the Audio sources window for the right channel.
• If a routing function is used mono, no source selection for the right channel is necessary.
Output Selector • Choose a selector from the list. Selectors can be created and edited under Audio/Monitor Functions.
Use Take • If you enable this check box, routing is done only after pressing the Take key. This option can be defined separately for each key.
Take • This key controls the optional Take function for the routing. It only needs to be configured once in every system.
Routing Selector • Choose a selector. If a Selector Source List is chosen for this selector, the sources of this list are shown after pressing the Routing Selector key. Select this source with the encoder and confirm it by pressing Take.

Resource Functions

option or subfunction selection description
Resource Request • The Resource Request key combined with the OK key allows a request to the corresponding free or occupied resource, the release from ownership (Release Mode) or the forced take over (Take Over, Special Take Over).
• You should configure the key in two colors, for example red for ON and yellow for OFF. This way, you can create the following conditions: - Off: The resource is taken by another participant. - Yellow, constant: Resource idle. - Yellow, flashing: The assigned resource is requested and must be released by the owner. - Red, constant: The resources is self-owned. - Red, flashing: The resource is owned by oneself and is requested by somebody else.

Overbridge Modules 52-4505A-E, 52-4301, 52-4303 and 52-4305

The layout of the universal module 52-4505 can be adapted within the scope of a defined pattern. The module can feature up to 5 pushbuttons or up to 3 potentiometers. A specific and thus clear arrangement of the pushbuttons on the module surface contributes to improved ergonomics and operation. Omitting particular pushbuttons from a fully equipped module with 5 pushbuttons results in 31 different combinations.

The following layouts are already produced:

52-4505a.jpg 52-4505b.jpg 52-4505c.jpg 52-4505d.jpg 52-4505e.jpg
52-4505A basis module 52-4505B 52-4505C 52-4505D 52-4505E

The same applies to the modules with potentiometers. Based on a maximum of 3 potentiometers, there are 7 different combinations. Furthermore, the circuit board of the module can also be fitted into the mixing console without front panel, then being controlled by external potentiometers.

The following layouts are already produced:

52-4303a.jpg 52-6509_3s.jpg 52-4301a.jpg 52-4305a.jpg
52-4303A basis module 52-6509A for up to 3 external potentiometers 52-4301A 52-4305A

The foil on the modules 52-4301A, 52-4303A and 52-4305A is imprinted with a default labelling in German. For other markings you can apply adhesive labels. Change requests concerning the original labelling can only be realised in connection with a minimum order and a delivery time of 12 weeks. For labelling changes or different module layouts it is necessary to contact DHD before ordering.

Important
In the Toolbox5 configuration software all variants mentioned above and to be available in the future are represented by the Overbridge Module 52-4505. The module 52-6509A is mounted beneath another overbridge module. However, it has to be configured as a separate module in the Toolbox5 software. Like any module, it needs an individual connection to a 52-4050 controller.

Overbridge Module RM420-013

The overbridge module RM420-013 has additional display elements and a chip card reader. The configuration of these additional functions is described in this subsection.

In the project tree, select <Device>/<Mixer>/Console. On the Console tab, drag the RM420-013 module from the Available Modules area to an empty slot in the Console Layout area. Select this module in your console layout. In the Other Options area, you can assign logic sources to the LEDs of the display elements MIC ON, ON AIR, PHONE 1 and PHONE 2.

Note
The labelling and the color of the LEDs can not be modified.

name of the function assigned element description
MIC ON lamp source Red LED-display labelled MIC ON. • You can select any logic source, for example a logic function that is OR-linked with the fader starts of the microphones.
ON AIR lamp source Red LED-display labelled ON AIR. • You can select any logic source, for example a logic function or a GPI signal for OnAir-routing a studio to the studio transmitter line.
PHONE 1 lamp source Yellow LED-display labelled PHONE 1. • You can select any logic source, for example a logic function or a GPI with calling signal or status signal of the phone hybrid.
PHONE 2 lamp source Yellow LED-display labelled PHONE 2. • You can select any logic source, for example a logic function or a GPI with calling signal or status signal of the phone hybrid.

RM420-013 overbridge modules that have been manufactured until May 2003 have an electromagnetic eject function for the chip card. For all modules produced later (from June 2003) the chip card has to be removed manually.

Two versions of card readers: Left: with electromagnetic eject (card with chip upwards); Right: removing card manually (chip downwards).

For card readers with electromagnetic eject, assign any logic source to the Card release source box which ejects the chip card. Often, the Eject Card key is used.
