Channel Assignment - Assigning Fader Channels and DSP Processing
In this subsection, you can assign the fader channels to the physical faders of the configured fader modules. Apart from that, in this window you can configure the signal processing for the input signals (input DSP processing).
Important
You should assign at least one fader channel to every physical fader.
If not, the physical fader is not included in the fixed processing. During operation, you can not assign a fader channel to a physical fader, which has not assigned any fader channel.
If you wouldn't want to assign an input to a physical fader, for example in your Setup 0, but want to assign a fader channel to this physical fader by using the Access key at the console, follow these steps:
1. In the project tree, select <Device>/<Mixer>/Fader Channels.
2. Create a fader channel and do not assign a source. (See Fader Channels)
3. In the General area, enter a name in the Label box, for example NOT ASSIGNED.
4. In the input pool list, select the desired input pool for this fader channel. (For creation of input pools see Input Pools)
5. In the project tree, select <Device>/<Mixer>/Channel Assignment.
6. Assign this fader channel to the desired physical fader. (See Fader Assignment)
You can assign each fader channel to a physical fader as long as you don't exceed the maximum number of faders. If you have configured a key on the console to toggle between Layer A and Layer B, you can use this key to toggle between the primary and secondary function for all physical faders with two configured layers.
Important
You can configure a maximum of 48 faders in both layers!
Example: On a console with 32 fader modules, all available fader modules are assigned fader channels in Layer A. This way, in Layer B 16 of the 32 fader modules can be assigned a second fader channel.
You can access the settings for both layers by selecting the Layer A or Layer B tabs. The available settings are identical for both layers.
Fader Assignment
The faders of the console are numbered 1 to 48. If the module IDs are consecutively defined from left to right, the left fader in the console is number 1, the fader to the right is number 2, and so on.
Important
The module IDs of the fader modules can be modified in the Maintenance Window. You should check for correct assignment, especially after taking the device into operation and after inserting spare parts, to avoid problems. If two fader modules have the same ID, they are working parallel and show identical channel names in the display. (See also Maintenance Window)
The Fader Assignment area contains two lists: the Faders list and the Defined Channels list. In the Faders list, the physical faders that are available are shown. The number of faders shown in the Faders list depends on the total number of configured fader modules. In the Defined Channels list, the available fader channels are shown.
To assign a fader channel to a physical fader, follow these steps:
- In the Faders list, select a physical fader.
- In the Defined Channels list, double-click on the fader channel which you want to assign. Alternatively, you can select a fader channel and click
, or drag a fader channel from the Defined Channels list to the desired physical fader in the Faders list.
After the assignment, the assigned fader channel disappears from the Defined Channels list, because it isn't available for assignment anymore.
To remove an assignment, select the physical fader in the Faders list and click 
. Alternatively, you can drag the assigned channel from the Faders list to the Defined Channel list.
In the Faders list, you can exchange the assignment of two physical faders by dragging an assignment from one fader to another fader.
Important
If working with input pools, you should mind the following:
• The sequence of entries in the Faders list determines the fader assignment after loading the Config to the device. To change the sequence of the fader channels for the Input Select function (by a rotary controller) change the sequence of the fader channels in the Defined Channels list under <Device>/<Mixer>/Fader Channels. (See also Fader Channels - Configuring Signal Sources)
• At least one channel per input pool has to remain in the Defined Channels list to be able to execute the Input Select function.
•You can assign one input pool to a fader or link the faders permanently to a fader channel that is not part of the input pool. This way, you can create a so-called fixed fader. However, you can not put one fader into more than one input pool.
Fader Configuration
In the Fader Configuration area, you can select the input DSP Processing for each fader. This processing is done before the fader changes the signal level.
Number, type and sequence of the corresponding DSP functions can be defined separately for each fader - except the faders that are assigned to input pools.
Important
For input pools, the input DSP processing is assigned to the pool itself - not to the separate faders. This means, that all faders with the same input pool have identical signal processing for input signals! Therefore, you have to configure them only once, it is then automatically and simultaneously changed for faders assigned to the same input pool.
To modify the input DSP processing of a fader, follow these steps:
- In the
Fader Assignmentarea, in the Faders list, select a fader with an already assigned fader channel. - In the
Fader Configurationarea, in the Available DSP Functions list, select the desired DSP function. - Click to assign the DSP function to the selected fader. Alternatively, you can double-click the desired DSP function or drag it from the Available DSP Functions list to the
Selected DSP Functionslist to assign it to the fader.
All assigned DSP functions for one selected fader are shown in the Selected DSP Functions list.
To remove a signal processing from the Selected DSP Functions list, select the DSP function in this list and click 
. You can also double-click on the DSP function or drag it from the Selected DSP Functions list to the Available DSP Functions list.
Note
The DSP functions are processed in the order which they are sorted in from the top to the bottom of the Selected DSP Functions list. You can change this order using drag & drop.
The following DSP functions can be used for the input processing:
| available DSP functions | max. number per input DSP processing | function |
|---|---|---|
| Limiter | 1 | Limiter |
| Compressor | 1 | Compressor |
| Expander | 1 | Expander |
| EQ | 4 | Equalizer per band, up to 4 bands possible |
| AGC | 1 | Automatic Gain Control |
| Sub Sonic | 1 | Sub Sonic filter (high pass 3rd order) |
| DeEsser | 1 | Deesser Important High system requirements! Use DeEsser2 to save DSP capacity if not enough resources are available. |
| DeEsser 2 | 1 | Deesser with reduced functionality demanding less processing power |
| Noise Gate | 1 | Noise Gate |
| Var. LP/HP | 2 | Variable filter, high pass or low pass filtering up to 10th order |
| Delay 1s | 1 | 1. Delay time: Adjustable between 0 s and 1 s in steps of 1 ms. |
| Delay 10 s | 1 | 1. Delay time: Adjustable between 0 s and 10 s in steps of 1 ms. |
| AGC (Automatic Gain Control) | 1 | 1. Velocity: Control speed in the range 0.3 dB/s to 1.5 dB/s (in steps of 0.1 dB/s). 2. Gain: Max. signal shift in the range 5 dB to 30 dB (in steps of 1 dB). 3. Level: Set output level in the range -20 dBint to 20 dBint (in steps of 1 dB). 4. Freeze: Freeze threshold of the AGC in the range -40 dBint to -20 dBint (in steps of 1 dB), for lower levels, the current or last value is recorded respectively. |
| Loudness AGC | 1 | Parameter set: See AGC. |
The adjustable parameters of these DSP functions are described in the section System Functions of the control modules. (See function Limiter and following)
Important
The configuration of the Input DSP Processing requires computing power depending on the number of configured faders! Not all combinations are possible, especially when using the Deesser function. Therefore, mind the DSP capacity bar below the project tree during the configuration.
