The codec supports both cue and talkback functions. Cue provides:
•Offline communications between local announcers via headphone outputs when the TB CUE button is pressed on inputs 1-3.
•Offline monitoring of the auxiliary input via headphone output 1 (HP1).
Talkback communication is available on inputs 1-3 between the remote codec and the studio. This requires a dedicated IFB channel when using a:
•Mono Peer-to-Peer + IFB program, or
•Stereo Peer-to-Peer + IFB program.
By default the TB CUE button on inputs 1-3 is configured in cue button mode. To change the operation of the TB CUE button, press the HOME
button to return to the Home screen, then tap Audio
> Inputs
> [tap to select an input] > Cue/TB Button Mode.

Typically, local cue intercom is configured for commentators to talk to each other offline. In cue mode, offline communications audio from inputs 1-3 is routed to the right side of all local headphone outputs (HP 1-3) when the TB CUE button is pressed. This is the same for:
•Mono Peer-to-Peer programs.
•Stereo Peer-to-Peer programs.
•2 x Mono Peer-to-Peer programs.
In the following matrix routing example, the CUE TB button for input 1 has been pressed and a stereo program is loaded in the codec. Cue audio is audible in the right side of HP 1-3.

Cue audio is only routed to an encoder in a program configured with IFB, e.g.:
•A Mono Peer-to-Peer + IFB program, or
•A Stereo Peer-to-Peer + IFB program.
This means that by default cue intercom audio is also routed to the IFB communications circuit back to the studio when using these programs.
The codec supports offline cueing of external sources attached to the stereo auxiliary input. By default, offline cue monitoring of the auxiliary input is only available via headphone output 1 (HP1).
In talkback mode, pressing the CUE TB button delivers ‘discreet’ talkback between local announcers and the remote codec. When an announcer presses an input's TB CUE button, audio is routed to the IFB audio stream encoder and outgoing audio is simultaneously monitored in the right side of the selected input's headphone output. Return IFB audio is also audible in the right side of the headphones. In other words, only the announcer using the CUE TB button monitors incoming and outgoing communications audio.
In the following matrix routing example, the CUE TB button is configured for talkback and a Mono Peer-to-Peer + IFB program is loaded in the codec. When the CUE TB button for input 1 is pressed, outgoing talkback audio is monitored in the right side of HP 1 and return IFB from the studio is also audible in the right side of HP 1.
