THRESHOLD
Sets the minimum amplitude needed for the
Compressor circuit to kick in.
GAIN MAKE-UP
Adds gain to the output of the Compressor to
compensate for the level lost from the dynamic
range reduction.
ATTACK
Sets how long the Compressor takes to react
once a signal passes the threshold level. Faster
attacks pick up transients but become more
noticeable. Slower attacks will miss sudden
transients but give a more subtle compression.
RELEASE
Sets how long it takes the Compressor to switch
off once the signal drops below the threshold
level. Again a faster release is more noticeable
and a slower release is more subtle.
RATIO
Sets the amount of level reduction once the
amplitude passes the threshold level. 2:1
decreases it by a factor of 2 where as 10:1
decreases it by a factor of 10.
BASS EXPAND
Adds a 350Hz high pass filter to the sidechain
meaning low frequencies don’t cause the
Compressor to activate. This stops bass
frequencies from ‘pumping’ and gives a more
full, consistent low-end.
IN
Adds the Compressor to the Mix Bus when
engaged.
GAIN REDUCTION METER
The Gain Reduction Meter displays the amount of
gain that is being reduced when the Compressor
is active.
Just getting the needle to bounce slightly is a
great trick for ‘sticking’ the mix together.
