Slower release times can smooth the transition that occurs when the signal
dips below the threshold, which is especially useful for material with frequent
peaks.
Note: Fast release times are typically only suitable for certain types of percus-
sion and other instruments with very fast decays. Using fast settings on other
sources may produce undesirable results.
Gate/Exp Meter This meter displays the amount of gain attenuation (downward
expansion) occurring in the gate/expander module.
Limiter/Compressor
The limiter/compressor module offers a continuously variable ratio between
1:1 (no compression) and infinity:1 (limiting). Signals above the threshold are
attenuated according to the ratio (RAT) value. Two attack speeds and contin-
uously variable release times are available, along with a pleasing automatic
triple time-constant program-dependent release mode (auto mode has a three-
stage release). A makeup gain control and a hard/soft knee setting are also
available in the module.
From the AMS-Neve 88RS User Manual: “Anti pumping and breathing cir-
cuitry allows the unit to operate on the source musically whilst retaining abso-
lute control over the dynamic range.”
The 88RS compressor has another nifty property: Two thresholds. When the
signal falls below the threshold, the compressor is releasing. But, if the signal
falls below a second (non-adjustable) threshold, which is roughly 40 dB be-
low the adjustable threshold value, then the release slows down drastically.
This acts as a “silence detector.” The concept is that if there is a quiet signal,
then the compressor should release to reduce the dynamic range. But if there
is a sudden onset of silence, it is likely that, when the signal returns, it will be
at about the same level as the region before the silence. So in that case, the
compressor doesn't release quickly.
