Band-Pass Filter Makes triggering of dynamics
processing more sensitive to frequencies within
the narrow band centered around the Frequency
setting, and rolling off at a slope of 12 dB per oc-
tave.
Low-Pass Filter Makes triggering of dynamics
processing more sensitive to frequencies below
the Frequency setting rolling off at a slope of
12 dB per octave.
HF Frequency Control
The Frequency control sets the frequency posi-
tion for the Band-Pass or Low-Pass filter, and
ranges from 80 Hz to 20 kHz.
Low-Frequency (LF) Filter Type
The LF filter section lets you filter lower frequen-
cies out of the side-chain signal so that only cer-
tain bands of low frequencies or higher frequen-
cies are allowed to pass through to trigger
dynamics processing. The LF side-chain is swit-
chable between Band-Pass and High-Pass filters.

The Frequency control sets the frequency posi-
tion for the Band-Pass or High-Pass filter, and
ranges from 25 Hz to 4 kHz.

Using an External Key Input for Side-
Chain Processing
To use a filtered or unfiltered external key input to
trigger dynamics processing:
Click the Key Input selector and select the in-
1
put or bus carrying the audio from the reference
track or external audio source.
Selecting a Key Input
Click External Key to activate external side-

chain processing.
External Key Side-Chain Listen
Side-Chain section
To listen to the signal that will be used to con-

trol side-chain input, click Side-Chain Listen to
enable it (highlighted).
To filter the key input so that only specific fre-

quencies trigger the plug-in, use the HF and LF
controls to select the desired frequency range.
Begin playback. The plug-in uses the input or

bus that you chose as an external key input to
trigger its effect.
Adjust the plug-in's Threshold control to fine-

tune external key input triggering.
