include de-essing (a side-chain boost at high frequencies) to help reduce sibilance, or the removal of rumble
modulation (a side-chain cut at low frequencies) which can cause pumping and breathing. It can also be set so
that the compressor will only respond to certain frequencies to even out the effects of resonance that cause
some notes to be much louder than others. Since the external side-chain input is routed through this filter when
this switch is engaged, it can be used to bandwidth limit a keying signal. For a description of the side chain-
function see #16.
16.
EXTERNAL SIDE-CHAIN ON: The side-chain is another name for an insert point in the input of the dynamic
section's RMS rectifier. Normally, the same audio signal is applied to the voltage controlled amplifier and its
detector, causing all processing to be controlled by the input, however there are instances when this is not what
is desired. If the control is to be given to another signal (to duck, for example), the input of the detector must
look at another input. A standard TRS insert jack is provided on the rear panel and is activated by this switch.
Any signal applied at the jack will not be seen unless the side-chain is enabled. This switch does not affect the
"parametric to side-chain" function which is always available.
17.
EXPANDER THRESHOLD: The expander is actually a downward expander that adds attenuation to the signal
as it decreases in level, following defined set points and curves. It behaves oppositely of compression. This
adjustment sets the level at which it begins operation. An LED indicates that this threshold has been crossed
and downward expansion has begun. If the input signal drops below the threshold's set point, the expander
fades it out according to the slope (ratio) set by the ratio control. The soft knee design smoothes the transition
from off to active by dynamically shifting the slope through the transition point. The attack and release times are
preset for best response.
18.
EXPANDER RATIO: The expander ratio is determined by dividing the input level by the output level. A ratio of
1:5 signifies that the output level has dropped five times as fast as the input. Ratios of 1:1.2 to 1:2 are typically
used to eliminate background noise and to dampen room reverberations. Higher ratios are used when gating is
required, and usually require lower thresholds to keep from cutting off the source too soon.
19.
COMPRESSOR THRESHOLD: A compressor is a circuit that reduces (or compresses) the dynamic range of the
input signal. A great change in volume is shrunk to a more manageable one. This particular adjustment sets the
point that this compression action begins. Any signal above this threshold will be compressed by the amount set
by the ratio control. If it drops below this point, the compressor has no effect. At the maximum threshold setting,
the compressor will be out of circuit for all signals except very high peaks. At the minimum setting, the source
will be almost continuously compressed. The attack and release times are optimized for vocal applications and
are program dependant.
20.
COMPRESSOR RATIO: The action of the compressor is determined by the compression ratio, which is the ratio
of the input level to the output level. A ratio of 3:1 signifies that the input level has increased three times as fast
as the output. (The dynamic range is compressed by a factor of three.) If the ratio is 1:1 the output exactly
tracks the input, and there is no compression. Ratios of 2:1 to 4:1 are typically used for vocals and musical
instruments. Higher ratios provide a soft limiting function, since the compressor uses a soft knee design with a
more gentle transition than the expander or limiter.
21.
LIMITER THRESHOLD: The limiter is an infinite ratio compressor. The threshold control defines the point that
absolute limiting begins. The limit LED will light when this threshold has been exceeded. To disable limiting, set
this control to maximum. The attack and release values are preset.
22.
COMPRESSOR GAIN: Adjusts the post-processing gain to make up for compression loss. It does not change
the input level to the dynamics' section. After the ratio and threshold controls have been set, adjust this for a
0 dB average indication on the output meters with the main level control centered and the blend turned fully CW
(wet).
