Remote sub level control
The low pass filter is
mostly used for sub-
woofers. It will allow low
frequencies only and
blocks higher frequen-
cies. A typical setting is
60 – 70 Hz.
The
LPF filter has two se-
lectable slopes 12 or 24 dB,
choose the slope that sounds
best in your installation.
Phase switch - S1
To get the best possible front stage from your
subwoofer installation you can choose the phase
shift between 0 ( button OUT ) or 180 degrees
( button IN )
Listen to the bass and choose the position that
gives the best front stage in your vehicle.
