COMPRESSOR
A compressor can be
switched into the main
stereo signal path when
required. Note that it is
located after the mix insert
point but before the main
fader.
The compressor
characteristics are
optimized for use in mix
processing while many of
the parameters remain
under the control of the
engineer.
Threshold, Gain Make Up,
Attack, Release and Ratio
are all adjustable while the
entire processor can be
switched out of circuit
when not required.
A bargraph meter indicates
the amount of compression
applied to the signal. When
compression is taking
place this should show
some very healthy activity.
Please do not try to over
compress the mix output
as the results will sound
terrible. Always use your
ears to check the effect that
you are trying for!
You too can act as a
compressor by reducing
and increasing the master
fader level. In some
situations this gain riding
may be preferable as,
assuming you know the
song, you will be able to
anticipate peaks and
reduce the gain slowly
before they occur,
increasing it slowly as the
signal level falls from the
peak.
A good use of the
compressor may be to limit
peak signals by setting a
highish threshold with a
high ratio. Thus when the
threshold is reached the
signal is barely allowed to
increase beyond it.

METER indicating the
amount of gain
reduction taking place.
2 THRESHOLD control for
determining the level
where compression
starts. Threshold can be
set between -20dBu
and +20dBu.
3 ATTACK controls the
speed with which the
compressor reacts to
the signal. Attack is
adjustable in 6 steps
from 0.1 to 30ms.
4 RATIO determines the
amount of compression
used once the signal is
above the threshold
level. High ratios means
that more compression
will be applied. For
example a ratio of 2:1
means that the output
will rise 1dB for every
2dB rise in input level.
Ratios of 4:1 and 10:1
are also available.
5 MAKEUP is a gain
control. When a signal
is compressed the level
is reduced. A gain make
up stage restores the
peak level although of
course the dynamic
range of the signal has
now been reduced.
40dB of gain make up is
available.
6 RELEASE controls the
speed at which the
compressor allows the
gain to return to normal
when the signal drops
below the threshold
level. Release is available
from 0.1s to 2.4s in 5
steps with an additional
AUTO setting.
7 The IN switch is used to
switch the compressor
into circuit.
