Gain Control Section:
This element is simple in its operation – the signal to be controlled
passes straight through, and the signal fed in from the side can ‘turn
down’ the main signal, but is never heard itself. To hear this control
signal, it is necessary to monitor the sidechain path.
The sidechain
LISTEN
signal may be monitored at the output, using the
LISTEN
key on the front panel. If the signal has been heavily compressed, chances are the
overall level will have dropped considerably. At this point it might be necessary to
introduce some additional gain to compensate for this loss.
Make-up Gain Section:
The introduction of extra (static) gain is best applied by ear, but the use of
the metering will aid the process. The intention is to make the input and
output levels of the unit match. Frequent comparisons using the ‘ACTIVE’
key to bypass the unit, and watching the gain reduction meter, which will show the
instantaneous amount of compression being applied, are the keys to matching the
levels.
Limiter Module:
Separate to the compressor is a fully independent limiter module. This
follows the compressor and is post-make-up gain at all times. It
determines the absolute maximum output level from the unit, set with the
threshold control. However, the
LISTEN
signal does not get routed through the
limiter, so be careful when engaging the sidechain monitoring.
Output Section:
As mentioned in the limiter section, the
LISTEN
key
is located just before the output stage, and routes the
output of the sidechain (equalised or not) to the main
output, so that it can be accurately tailored to achieve
the desired response. The output is then converted
back to analogue or transmitted as a digital signal to an
independent output. Note that the digital output is a factory fitted option – please
see Appendix 1 for further information about this.
Now that the main building blocks have been explained, their interactivity and
connections can be outlined with reference to the two modes of operation.
