Neve 8424 - Advanced Return Talkback Uses; Producer Mic and Recording Input Functions

48
Producers Sofa Mic 1
As an alternative, the 8424 return talkback can be used to create a second
talkback feed from the control room into the live room. In this mode, the
RTB signal is not sent to M2, (as is the case for the Live Room Return
Talkback mode) but instead is sent to the CUE bus. This allows a producer at
the back of the room to talk to performers by using a switchable producer
microphone connected to the RTB MIC input along with a remote switching
device connected to the DC REMOTES 15-Pin connection at the rear of the
console. Producer Talkback mic gain and compressor settings are adjusted at
the rear of the console, Phantom power is set in the services screen at
TB>RTB +48V: [Y]
Producer talkback is unaffected by RTB TB trim.
When the Producer Mic is in use, the CUE TB button will flash to indicate
that the producer RTB is active. The engineer can override the RTB producer
mic by pressing and holding the CUE TB button. Producer talkback is
automatically patched to the same aux and cue busses as the 8424’s internal
CUE TB, no additional patching is required. The Producer talkback will also
activate the TB DIM in the same way as the engineer talkback system. CUE
TB and DIM will flash indicating Producer return talkback active.
Engineer talkback is always the Master Talkback system.
Additional Recording Input 1
The Return Talkback system also has the ability of becoming an additional
recording input from the live room. The Return Talkback mic in the live room
is connected to the console RTB MIC XLR input connector on the rear of the
console. This signal passes through the adjustable internal RTB microphone
preamp and compressor circuit within the console and is routed out of the
RTB O/P XLR connector at the rear of the console. This can then be patched
manually with an XLR>¼’’TRS cable back into any console channel Input B
and mixed along with the other console channel inputs, alternatively this
can be patched directly into the audio interface and recorded into the DAW.
In this mode the RTB circuit does not need to be activated either from the
services screen or from the RTB button on the console surface. The mic
simply needs to be patched to wherever it is required, with the phantom
power, gain, compressor and RTB TRIM settings set appropriately.
