The high pass filter
blocks
very low
frequencies from reaching
the speakers. It is mostly
used at say 60 Hz to
protect small speakers (
like 6 inch and smaller )
from deep bass.
Set the filter to 15 Hz po-
sition if you want to run the
amplifier in full range
mode (almost).
The filter can not be
switched off.

The
phase control
can be set
continuously from 0 - 180
degrees.
This function is used together
with subwoofers. This is very
useful when you want to adjust
the bass sound for best front
stage image. 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.
