LOW PASS FILTER
( 40Hz ~ 300Hz @ 12dB/Oct )
Controls the low pass filter for the
speaker outputs.
GAIN ( 6V ~ 0.2V )
The gain control matches the voltage of the head unit's
RCA line-outs to WDX amplifiers' input section.
SUBSONIC FILTER ( 10Hz ~ 40Hz @ 12dB/Oct )
Controls the high Pass filter for the subwoofer outputs
to eliminate extreme low frequencies that can damage
your subwoofers.
BASS EQUALIZER (0-9dB @45Hz)
The Bass EQ allows you to boost the low-end
frequencies centered around 45Hz. This is helpful for
tuning your enclosure to your vehicle. The setting will
vary according to gain setting, enclosure and
vehicle type.
