9.5 Gain
As compression is a gain reducing process, the output signal level will often
be less than the input. The
gain
control is provided to restore the output signal
to the desired operating point, and provides a range of +/-20dB relative to the
input signal. The facility for gain loss provided by this control can also be
used, when required, to restore the compressed signal to a point lower than
the input signal and might be useful, for example, when connecting the output
to a high sensitivity input on a following piece of equipment.
9.6 Side chain
listen
Depressing this switch disconnects the main compressor output of the unit
from the normal compressor output and connects it instead to the output of the
parametric filter controlled with the
width
and
frequency
controls. This allows
the filter to be configured more easily to select the sounds that are to be
compressed.
As operating the
side chain listen
control bypasses all compressor functions, in
this mode the DPR 944 is acting as a dedicated high quality parametric
bandpass filter. Although a slightly unusual application, this is a useful
additional feature.
9.7 Frequency
This and the
width
control endow the DPR 944 compressors with the unique
ability to select a portion of the audio band and compress
only
that band
(other compressors have the ability to select a given frequency band, but once
activated, compress the whole band).
