Talkback User Button & Connector
Rear Panel Connectors
The female XLR on the Central Panel (976/20) can be used to connect a talkback microphone.
It is wired directly to the male XLR (marked TB) on the console's rear panel. Note that the console does not
include a dedicated talkback mic preamp, and so the rear panel TB connector must be wired either to an
external communications system (via a mic preamp), or to one of the console's local IO mic/line inputs.
