The TB or Talk keys can be used to talk to a source or monitor output. The number of talkback keys, and their operation, is determined by the configuration. The configuration possibilities are explained later. For now, it is useful to know that:
- Up to 8 talkback sources can be configured (to support more than one talkback mic).
- A central rotary control can be configured to adjust talkback level.
- The operation of the talkback keys can be either momentary or latching.
- While talkback is active, the main signal can be either dimmed or muted.
The rest of this topic describes how talkback is defined in the standard configuration. The operation may vary if the configuration is customized.
Operation
In the standard configuration, the following operations are possible.
1. Talk to Source
Press and hold TB on a fader strip to talk to a source. This function is supported for all sources with an N-1 return. i.e. all microphone and codec sources.
2. Talk to Guest or Studio
Press and hold TB on the Central Rotary Controls to talk to the guest or studio monitor outputs.
3. Talk to All
Press and hold Talk All on the Central or Combo module to talk to the guest and studio monitor outputs, and all available N-1 returns.
4. Talkback Level
On a Central module, the talkback level can be adjusted from the first Central Rotary Control. This function is not supported by a Combo module. In both cases, the initial level is set to 0dB.
All of the talkback keys are momentary so press and hold for as long as you wish to speak. In each case, the main signal is dimmed by 20dB while talkback is active.
Each talkback key has two possible states. The colors used can be modified by the ON-AIR Designer. The following colors are used in the standard configuration:
- Dim white = talkback off.
- Full red = talkback on (active).
Talkback Source
In the standard configuration, the talkback source is defined as Mic Input 1 (from the Studio I/O card). This can be changed by editing the configuration (using the ON-AIR Designer).
