Front panel controls
Detection section
HP Freq
The
HP Freq
control allows you to apply a variable high pass filter on the key signal that is used for the
compressor’s amplitude detection circuit.
This can be useful when there is too much low-end in the signal fed
into the peak detection circuit, which can result in the compressor
reacting too heavily.
Listen
Activating the
Listen
button allows you to monitor the signal used for
the compressor's detection circuit (if the Sidechain input is connected
on the rear panel of DCAM BusComp, the signal connected to it is
monitored).
The signal is monitored after the
HP Freq
function is applied.

Dynamics section
Attack
The
Attack
control adjusts the speed at which the input signal's gain is reduced when a peak is
detected.
Six attack times are available: 0.1 ms, 0.3 ms, 1 ms, 3 ms, 10 ms, 30 ms.
Release
The
Release
control sets the speed at which the gain level returns to normal after a transient has
passed.
The following Release settings are available: 0.1 secs, 0.3 secs, 0.6 secs, 1.2 secs and Auto.
Compressor section
Threshold
The
Threshold
represents the input level at which the compressor starts to react - any signals over the
Threshold level engage the compressor circuit.
Ratio
The
Ratio
specifies the gain reduction applied by the compressor.
3 Ratio settings are available: 2:1, 4:1 and 10:1. The numbers represent the change in gain after
compression.
For example, assuming that the threshold level has been breached, then a Ratio of 4:1 would mean that
for every 4 dB of in- creased signal level coming into the compressor, the output level rises by 1dB.
