input signal.
S IDECHAIN R OUTING B UTTON
This button (labeled “chan” in the illustration) is used to con-
trol the routing of the input signal to the gate sidechain.
When the button is in the “chan” state, the signal used by the
sidechain is the signal being processed by ChannelStrip.
When the button is in the “sc-in” state, the signal used by the
sidechain is the input or bus selected in the “side chain
input” popup in the Pro Tools plug-in window header. If
nothing is selected in that popup, the input to the sidechain
will be silence and the gate will never open.
F ILTER TYPE BUTTON
This button (indicating a peaking/parametric filter in the
illustration) is used to select the filter type of the single band
of side chain EQ. You may choose from 6 different types of
filters:
• Peaking/Parametric – a second order bell-shaped paramet-
ric boost/cut filter. Boost/cut has a range of ± 24 dB. When
the boost is greater than +15 dB the filter gains a resonant
quality. The center frequency of the filter can be any fre-
quency between 20 Hz and 20 kHz. The bandwidth of the
filter is continuously variable between 0.1 octaves and 2.5
octaves.
• High Cut – a 12 dB/octave high cut filter with a -3dB point
that is continuously adjustable between 20 Hz and 20 kHz.
• Low Cut – a 12 dB/octave low cut filter with a -3dB point
that is continuously adjustable between 20 Hz and 20 kHz.
• Low Shelf – a shelving filter that applies boost/cut to low
frequencies. Boost/cut is limited to +12 dB/– 24dB. The
