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, or Compression, depends upon the
THRESHold, RATIO and TYPE settings and the input signal level. eg. An
input signal within the filter pass-band, 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 THRESHold. 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 is set to
Auto
Auto the attack time is programme
ATACK
dependant which woks well on most material causing the compressor to
be 'Transparent'. eg. if a fast transient appears the attack rate will be fast,
slowly changing levels will have a very slow attack rate.
The time Gain Reduction holds each time the signal causes an increase in
HOLD
Gain Reduction. Useful for low frequency sounds to prevent 'Rattle'. HOLD
time 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 with which gives the user greater control
TYPE
of compression with fixed RATIO relationship applying to all signals above
the THRESHOLD.
Soft
Soft This being a
Soft
Soft-Knee type compressor which is very transparent. In Soft-
TYPE
Knee mode however, the compression ratio increases as the signal level
increases and so there is no hard and fast threshold as such. In Soft-Knee,
the THRESHOLD parameter is used to adjust the amount of compression,
and RATIO alters the curve of the knee, making it softer or harder on a
scale of 0 to 9.
The audio outputs of the
1<--
1<-- type Effect can be sent to both channels by
selecting LINKS option to display
1<>2
1<>2
OUTs
Because the DE-ESSER is effectually the COMPRESSOR with the FILTER
in the side-chain, changing any of the DE-ESSER parameters will also
cause the COMPRESSOR parameters to change and vice versa.
The De-Esser requires the link to be
Off
Off to allow different
Ds/Cp/Lm
THRESHold RATIO etc parameter settings for each channel. Also select
OUTPUT to be
0dB
0dB to reduce the undesirable signal

components.
