COMPRESSOR SECTION
Comp/Byp Switch:
This switch activates the compression circuit. It does not affect the
gate circuit. The Bypass is a
soft
bypass. This means you can still have the benefit of
the Class A Input buffer stage.
THRSH Rotary:
This is the
Threshold
control for the compressor. Threshold
Settings: From +10db to -30db. This sets the level at which the compression will
start. If the input level exceeds the set value the compression circuit will start to
compress the input signal.
Ratio Rotary:
Ratio Settings From 2 to 8. This sets the ratio of the compression,
or how much the compressor reigns-in signal that over-shoots the level set with
the
Threshold
control. A lower setting (2) is more gentle at bringing the overshoot
under control, whereas a higher setting (8) will be a more aggressive or “brick-wall”
control. Or, (for instance) for every 8dB over the threshold the compressor will only
allow 1dB to pass through.
Fast Switch:
The
Fast
switch deals with attack times. The N90 has an auto attack
time built-in that generally covers most situations. Occasionally a signal with very fast
transients will need a faster attack time than the auto. Switching the
Fast
switch down
will engage the faster attack-time. The auto time is around 15mS, and the Fast is
around 1mS.
Rel Rotary:
Release
time from 0.1 seconds to 3 seconds. This controls the period
of time between when the signal falls below the compression threshold and the
compressor stop compressing the signal.
Auto Switch:
The
Auto
switch is an
Auto Release
that takes over from the
Release
rotary control. Switching it down activates a dual timing circuit that uses combined
release times that vary automatically with the input. The
Auto
automatically uses a
fast release on fast transients and a longer release time on the slower transients.
The Auto release is very
program sensitive
and is sometimes used for gain riding
applications.
