PHASE switch:
The phase can be adjusted in either
0 or 180 degrees. This is used to get
the best possible "front stage" from
the subwoofer.
SUB EQ is used to increase the bass
volume at a low frequency.You can
select the amplification between 0 dB
( no amplification ) and +6 dB ( full
amplification ) at 40 Hz center
frequency.
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.
