Talkback
500R8 features a comprehensive Talkback system that
can be used to communicate with musicians located
around the studio space.
The Talkback signal is sent to 500R8’s Aux Headphones
and Output jacks as well as the C.A.S.T. connectors to
enable communication with all musicians connected to
500R8 via C.A.S.T. breakout boxes.
Talkback Input
The Talkback input is located on the rear panel of 500R8
and features an XLR connection that can be connected
to an external microphone to access the talkback
features.
The Talkback Input is a fixed-gain mic preamp with 30dB of gain and 48v phantom power
enabled to enable dynamic or condenser microphones to be used.
Talkback Level
The Talkback Level control is a variable gain control with 30dB of level on tap that is used to set
the level of the talkback signal globally to its multiple destinations.
Talk Key
The Talk key operates in a momentary “push-to-talk”
fashion and is used to activate the talkback feature and
send the talkback signal onwards to its associated
destinations.
When the Talk key is depressed, the Aux Bus mix is
ducked by 12dB in volume to allow the musicians to
hear the Talkback over the top of the Aux mix.
The Talk key also temporarily enables the Speaker Dim
function to reduce the volume in the control room and
achieve a more intelligible talkback signal through the
talkback microphone.
