+18 dB
This function is used to compensate for the bass
box function and to adjust for your own taste of bass.
Set level control at 0 dB if you want it to be
inoperative.
NOTE! Use the bass boost very carefully. The
sound can be destroyed if you turn it up to high.
Start at 0 and turn the control slowly clockwise until
you experience that the bass sound is coming from
the front. If you don’t get the result you want, also try
to phase reverse the subwoofer connections and
make a new adjustment.

The low pass filter is mostly
used for subwoofers. It will allow

higher frequencies.
A typical setting is 50 – 70 Hz.
