A meter is provided to display the amount of gain reduction that is applied to the signal as a result of
expansion.
Parameters:

In/Out When set to In the expander is active; when set to Out the band suppressor is bypassed.
Out Gain The output gain parameter may be used to increase the gain by as much as 24 dB, or
reduce the gain to nothing. Note that the Out Gain parameter does not control the signal
level when the algorithm is set to
Out .
Fund FreqC The coarse frequency control sets the fundamental frequency of the harmonic structure to
be expanded. Since the
fi lter is a comb fi lter, the separation between harmonically related
expansion bands is also controlled.
Fund FreqF The fi ne frequency control sets the fundamental frequency of the harmonic structure to be
expanded. Since the fi lter is a comb fi lter, the separation between harmonically related
expansion bands is also controlled.
Harmonics Sets the harmonic structure of the expansion comb fi lter. When set to Even , only the even
harmonics of the speci fi ed fundamental frequency (including any dc signal level) are
expanded, with no expansion of the fundamental. When set to Odd , the odd harmonics,
including the fundamental, are expanded. The All setting expands all even and odd
harmonics including any dc signal level. The All setting is the same as the Even when the
Even frequency is set to half the value of All .
SC Input Select the input source channel for side-chain processing—left ( L ), right ( R ) or both
( L & R) . When set to L & R , the maximum of left and right amplitudes is used.
ExpandChan Select which input channel will receive expander processing—left, right or both. If you
select left or right, the opposite channel will pass through unaffected.
Atk Time The time for the expander to increase the gain of the signal (turns off the expander) after
the signal rises above threshold.
Rel Time The time for the expander to reduce the signal level when the signal drops below the
threshold (turning on expansion).
