NARROW L.F. CONTROL COMPRESSION
Only frequencies below that set on the FREQ
control are compressed. Low frequencies are
compressed without modulating the high
frequencies, which pass unattenuated. The
PEAK LIMITER and DE-ESSER should not
normally be used in this mode.
K-G L-B
EXPANDER - WIDE BAND
When input signals exceed the set threshold,
expansion occurs, since the subtract side
chain signal is added to the main signal. The
DE-ESSER should not normally be used in this
mode. The PEAK LIMITER may be used for
effect.
C-G D-B
H-J
EXPANDER - L.F. ONLY
As above, but only those frequencies below
that set by the FREQ control are expanded.
K-H L-B
EXPANDER - L.F. CONTROL. (MODE switch
to COMPRESS) D-H L-B
EXPANDER - H.F. CONTROL. (MODE switch
to DE-ESS WIDE)
As in wide band, expansion occurs over the
entire audio bandwidth. However, it is under
the control of either low or high frequencies,
as set by the links and FREQ control.
D-H C-B
EXTERNAL GAIN CONTROL
By driving the control s/c with an external
signal, the amplitude of the main signal will
be modulated by the envelope of the external
control signal. By choosing links on the
subtract s/c, modulation can be wide band or
L.F. only. DE-ESS and PEAK LIMITER should
not be used in this mode.
D-G EXT SIG
K-G
AMPLITUDE CONTROLLED MIXING (1)
In this mode, an external signal will be
summed with the main signal and appear on
the compressor, under control of the
amplitude of the main signal. Wide band link
C-B, L.F. only link K-B, H.F. only link C-B
and MODE switch to DE-ESS WIDE.
