This sets the signal input level over which Gain Reduction will start to
THRESH
occur. The manual threshold ranges from -30dB -30dB to +15dB +15dB (a setting of
+15dB will cause very little audible change).
For details of the
Auto Auto setting see above.
This determines how much Gain Reduction occurs when the input signal
RATIO
goes above THRESHold. The parameter range covers from 1.1:1 1.1:1 to 20:1 20:1,
with TYPE set to Norm Norm, or, from Sft:0 Sft:0 to Sft:9 Sft:9 with TYPE set to Soft Soft Knee.
The amount of Gain reduction (Compression) depends upon the
THRESHold, RATIO and TYPE settings and the signal level. eg. A signal of
0dB with a THRESHold setting of -20dB with RATIO set to 2:1 will give
10dB of compression.
ATTACK is the rate at which the Gain Reduction increases once the input
ATACK
signal exceeds THRESH. Longer attack times allow more transients
through unprocessed. The manual range of this parameter is
50µs 50µs (letting
no transients through) to 20ms 20ms (which allows most transients to pass
through). When [ATACK] is set to Auto Auto the attack time is programme
dependant which woks well on most material causing the compressor to
be 'Transparent'. e.g. if a fast transient appears the attack rate will be fast,
slowly changing levels will have a very slow attack rate.
HOLD is the time Gain Reduction holds each time the signal causes a
HOLD
increase in Gain Reduction. Useful for low frequency sounds to prevent
'Rattle'. It can be disabled,(
Off Off), or set from 2ms 2ms through to 10S 10Seconds.
RELEASE is the rate at which the Gain Reduction falls back to RANGE
RLESE
amount of Gain Reduction. Very short release times give maximum effect
but can cause severe 'Pumping' or 'Breathing'. This parameter ranges from
50ms 50ms through to 10S 10Seconds. Auto Auto release is a programme dependent
release time which works well on most material causing the compressor
to be 'Transparent'
Norm Norm Norm Normal is a 'Linear' compressor which gives the user greater control of
TYPE
compression with fixed RATIO relationship applying to all signals above
the THRESHOLD.
