GAIN – make t what doesn‘t t
The GAIN control sets the input level in order to match the Action Filter 4’s input to different
output levels of connected units such as DJ-mixers, groove boxes, audio-interfaces etc. In case, the
output level of the connected unit is pretty high by default, the Action Filter 4’s inputs may clip.
This is indicated by a red LED located top right of the GAIN control. Typically, the level should be
set in a way that the LED only lights up shortly at absolute peak levels.
☛
Overdrive created by high input gain settings can be used intended to create
especially powerful sounds. This will not harm the Action Filter 4.
TRIGGER BYPASS - momentary or permanently
The BYPASS switch placed in the center of the unit toggles between the filtered and unfiltered
audio signal. In ON position, BYPASS is active, meaning the filters are inactive, passing the source
signal to the outputs. This is indicated by a blue LED.
With the switch set to OFF, the filter is active and the blue LED unlit.
Nearby the switch, you will find the TRIGGER button that works like a transformer function on
a DJ-mixer. This button activates or deactivates the Action Filter 4’s filters for the period of the
button-pressing. TRIGGER functions contrarily to the BYPASS switch. With BYPASS set to ON
(filters off, LED lit), TRIGGER button will activate the filters temporarily. With BYPASS set to OFF
(filters active, LED off), TRIGGER button will temporarily bypass the filters.
