HARD knee compression provides tight control over signal levels above threshold
and is useful for creative applications or where a large amount of gain reduction,
such as limiting, is required.
2.7 RELEASE control
RELEASE is only active in MAN (manual) mode (AUTO-MAN switch in) and
adjusts the release time between 40mS and 4S.
2.8 GAIN control
The GAIN control on the C400 allows the output level from the compressor to be
attenuated or amplified by up to 20dB. Generally used to compensate for level
changes caused by the action of compression.
Please note:
As +20dB of gain can be added to the signal path it is possible to cause clipping.
2.9 GAIN REDUCTION display
An 8 stage led bar graph meter that provides a visual indication of the amount of
gain reduction being applied to the input signal.
2.10 LINK switch
Pressing the LINK switch couples channels 1&2 and 3&4 for stereo operation.
Channels 1 and 3 become the masters, the controls on channels 2 and 4 are
disabled.
The side chain circuitry on the C400 uses true rms summing to ensure that the
signals in both the linked channels contribute equally to any gain reduction.
