•[LR BOTH]
For a stereo channel component, both L/R input signals are used as the trigger
source.
The higher of the L/R input signals will be the trigger.

7 [RANGE] knob
Specifies the amount of attenuation applied when DUCKER is active.
8 [ATTACK] knob
Specifies the attack time (the time from when the input signal exceeds the
THRESHOLD until the amount of attenuation specified by the [RANGE] knob is
reached).
9 [HOLD] knob
Specifies the hold time (the time from when the input signal falls below the
THRESHOLD until attenuation begins to be removed).
0 [RELEASE] knob
Specifies the release time (the time from when the hold time specified by the [HOLD]
knob has elapsed until DUCKER is no longer applied). The setting is expressed as the
time required for the level to change 6 dB.
