TALKBACK and LISTEN MIC

In the image on the right we can see the TALKBACK and LISTEN
sections in the Master Section. The TALKBACK section has an XLR input
for a Master Section mounted (or connected) Talkback Microphone, a
hole for a flat blade trim tool to access and adjust the gain trim setting for
the Talkback microphone input and a +48V phantom power switch for the
input. Similarly the LISTEN section has a hole for a flat blade trim tool to
access and adjust the gain trim setting for the Listen Microphone Input
and a +48V phantom power switch.

Talkback Microphone Connections (Mic and Line Inputs)

The Talkback Amplifier has a front panel XLR connector, as shown in the picture above, it also has a paralleled connection on the
"EXTERNAL INPUTS" DB-25 rear connector if an externally located Talkback mic is desirable. If this DB-25 input is connected to
a patchbay, it allows the external Talkback Mic Amp to be over patched.
After the Talkback Mic Pre gain stage there is a second, summed, line-level input available on the "MAIN MIX INS RTN & TB/LM
IN" DB-25 rear connector. This can be seen in the lower half of the block diagram above. This allows an externally amplified Mic
Pre signal to be fed through the Talkback Mic Compressor (This is the same circuit as the infamous SSL Listen Mic Compressor).
With the SWITCHED EXT TB OUT switch pressed in the COMMUNICATIONS part of the Master Section, there is a Talkback Mic
output signal on the "MAIN MIX OP & INS SEND" DB-25 rear connector (and on the patchbay, if connected), this gives an input and
output path to use this compressor creatively. If you are using this feature, don't forget to disconnect, or over patch the Talkback
Mic Amp connections to prevent the talkback mic signals being summed with the external Line input!
