1 - COMPRESSOR
Threshold
Determines the input level above which gain reduction will be applied. Soft knee compression takes place for
signals exceeding the threshold level by a few decibels, above which level conventional 'ratio' compression is
applied.
Ratio
Ratio determines the amount of compression (attenuation)
to be used once the 'soft-knee' region is exceeded. If the
ratio is set to 5:1 a signal exceeding the threshold by 5dB
will be attenuated down to 1dB above the threshold, and
likewise, a signal exceeding the threshold by 15dB will be
attenuated down to 3dB above it. A ratio of 1:1 provides no
compression, 4:1 is moderate, 8:1 strong, whilst 10:1 would
be seen as approaching limiting.
Gain Reduction Meter
An eight segment LED bargraph meter continuously monitors
the gain reduction applied by the compressor and gives an
indication of the amount of gain required to bring the signal
back to its input level after it has been compressed.
Attack
Sets the rate at which the compressor will respond to input
signal that exceed the threshold level.
Release
Sets the rate at which the system gain returns to normal
after the input signal level has fallen below the threshold.
