The HTPS-400 contains a
signal-sensing auto turn-on/
turn-off circuit. This feature
will automatically turn the
subwoofer on when you turn your system on with the power
switch in the “Auto” position
and begin playing any program
material. The subwoofer will
return to standby mode when no signal is received for
approximately 15 minutes. The
power switch’s “Off” position
is for vacation use only.
The Crossover Frequency
adjustment determines
the highest frequency the
HTPS-400 will reproduce. It
allows a seamless transition
from the subwoofer to the satellite speakers. Experiment
with this adjustment to
find the crossover frequency
that sounds best with your
speakers. Note : When the THX/Normal
switch is set to “THX,” the
internal crossover is bypassed.
Crossover frequency is then
adjusted at the THX processor.
