CONTROL DESCRIPTION
CHAPTER 2
1 MAIN COMPRESSOR CONTROLS
Threshold: +20dB - -26dB
Determines the input level above which gain reduction will be applied.
In order to provide as transparent processing as possible Soft knee
compression takes place for signals exceeding the threshold level by
a few decibels, above which level conventional ‘ratio’ compression is
applied.
Gain Reduction Meter:
Eight Leds at 0,-1,-3,-5,-7,-10,-15,-20dB
Ratio: 1.4:1 - 10:1
Sets the final compression ratio that will be applied once the 'soft-
knee' region of the threshold control is exceeded.
A ratio of 1:1 provides no compression, whereas approaching 10:1
corresponds to more of a limiter.
Attack: 0.2mS - 100mS
Controls the speed that the compressor responds to signals that exceed
the level set by threshold. For most musical uses, an initial attack
setting of between 1 and 20 mS is typical and least obtrusive, with
slower settings allowing the start of a percussive or transient signal to
pass unaltered, before the compressor reacts. However, bringing the
level under control quickly, using a very fast attack time, generally
gives more natural results on vocals and mixes.
Auto Release: Off - 1 - 2
When selected, Auto disables the Release control and continually optimises the release times to suit the dynamics
of the material being processed - with 1 having a slightly quicker release than 2 to further suit the varied signals. In
general, this setting will produce the least obtrusive level control on signals with widely varying dynamics such as
complete mixes.
Release: 0.05S - 2.0Seconds
Sets the time taken for the signal to return to normal after the input level has fallen below threshold. For most
signals setting the realease at around 0.2 to 0.6 seconds is a good starting point. Be careful with very long release
settings, the Compressor might never have enough time for a total recovery between the signal peaks. However, if
set too fast, the signal may “pump”, which can be used creatively, but is generally undesirable.
