Talkback, Aux Masters, Bus Masters and Master Fader

Talkback​

ASP4816-SE Talkback level and destination controls

The Talkback Mic input provides 48 V phantom power by default, allowing condenser microphones to be used. Phantom power can be disabled using an internal hardware link; contact Audient Support before changing this configuration.

ControlFunction
LEVELSets talkback level
SLATE BUS OUTPUTSRoutes talkback to the record-bus outputs
STUDIO LOUDSPEAKERRoutes talkback to the Studio output
ARTIST FOLDBACKRoutes talkback to both Foldback outputs

The Studio Loudspeaker (SLS) and Artist Foldback (FB) talkback functions can also be controlled from the rear-panel footswitch connections using a latching footswitch that shorts Tip to Ground when active.

Activating a talkback destination automatically dims the Control Room monitoring. This automatic DIM affects the control-room monitor level; it does not reduce the selected Talkback destination output.

Aux Masters​

ASP4816-SE Aux Master level, Solo and Link controls

Each Aux bus has an overall master level and an AFL solo. LINK allows separate LF/SF-derived Aux mixes to be combined into a common output.

Bus Master Trim​

ASP4816-SE Bus Master Trim controls for record buses 1–16

Each of the 16 record-bus outputs has a final ±10 dB Bus Master Trim for setting the corresponding bus-output level.

Master Fader​

ASP4816-SE Master Fader

The Master Fader controls the stereo Mix output. Its top position is 0 dB (unity gain), with attenuation below this point.

During normal operation, keep the Master Fader at 0 dB where practical. If substantial attenuation is required to achieve the desired output level, reduce the levels feeding the stereo Mix bus instead.
