Groups
A detailed block diagram of the Groups may be found in the Appendix on
page 76.
The CDC FOUR has four mono groups, with outputs on the rear panel. They may
be used either for recording or other external purposes, or the outputs may be
ignored, and they can form subgroups into the main stereo mix.
Some channel functions are absent from groups (relative to the input channels).
The differences from a mono channel are summarised below. The description of
the mono mic/line channel applies in all other respects. Refer to Page 32 onwards
for full details.
Input stage:
All input functionality is removed. The Input Trim, high-pass filter and phase
controls are inoperative and their virtual counterparts do not appear on-screen.
Noise gate:
The groups do not have noise gates. All noise gate controls are inoperative and
their virtual counterparts do not appear on-screen.
Limiter:
The groups’ dynamics sections have a dedicated limiter as well as the compressor
section fitted to the input channels.
THR - adjusts the threshold of the group’s separate limiter section in the range
-40 dB to +21 dB. Default setting is +21 dB (i.e., no limiting).
IN - switches the limiter into the signal chain. Default is Out.
Aux Sends:
The groups do not have Aux Send facilities. All Aux Send controls are inoperative
and their virtual counterparts do not appear on-screen.
