The gain knob is not a volume control.
It is designed to match the input level
of the amp to the output level of the
source unit. Over driving -clipping- the
input stage of the amp will cause
damage to the amplifier (Please refer
to table for settings).

This switch will reverse the phase of PH10000's
output with respect to its input. Although the position
that yields the most upper bass is technically correct,
you may choose the position that better suits your
needs. Peaks or dips occur at about 40Hz —
around the frequency of a low bass
guitar note. Use this control
to correct that peak or dip.
The low-pass filter,
blocks unwanted high
frequencies to allow
cleaner low-frequencies. This switch will line
match the voltage of your
head unit, which will
deliver high sound quality
and performance.
