4.11 TALKBACK
The console is fitted with a talkback microphone and amplifier with automatic gain control.
The gain can be set for a given operator on a separate gain control and should then remain
reasonably constant despite his movements.
The talkback can be selected to several destinations.
Main 1 & 2
Aux 1 then 8 or Aux Master (all 8 simultaneously)
Slate (all Multitrack outputs)
External outputs 1 to 3
(Ext 3 can be Studio LS)
Ommi - all selections simultaneously
The talkback to Main Outputs & Ommi is inhibited when ON AIR is selected.
The Slate output to Multitrack is accompanied by a 30Hz low level tone (Slate oscillator)
for tape search when spooling.
There is a reverse talkback system comprising an input intended to be from the studio
with a gain control (RTB) and a second external input with a gain control (EXT).
The reverse talkback is fed into the PFL mixer left input.
4.12 STUDIO LOUDSPEAKER
Provision is made at the top of the console for feeding signals to loudspeakers and
headphones in the studio.
Selections can be made as follows:-
Main 1 (Desk)
Main 2 (Desk)
External inputs 1 to 3
LS (Follow Monitor LS Selection)
There are separate gain controls for the loudspeaker and phones outputs which are in
Stereo. There is a CUT button & cut is automatic in certain conditions to avoid howl round
- see section 5.10.
4.13 COMPRESSOR/LIMITERS
The DL3678 module, several of which may be fitted in the upper part of the console, is
an outboard unit requiring to be connected to the channel, group or main insert.
It operates at standard line level (0dBu) and is balanced in & out.
The unit comprises separate limiter & compressor circuits with a common gain reduction
bargraph up to 24dB. Limiting is shown separately also on a Peak Limit LED. The limiter
& compressor may be switched in independently & the complete module can be bypassed
- when the DYN button is not pressed.
In all off conditions the effect of the limiter & compressor may be observed dimly on the
gain reduction bargraph.
