OP ERATION
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 power switch’s “Off” position
material. The subwoofer will
return to standby mode when
no signal is received for
approximately 15 minutes. The

Crossover Frequency – Normal (non-THX) Modes 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.

adjusted at the THX processor.

Phase
The Phase switch is used to
adjust the relative polarity of
the subwoofer to the other
speakers. When the speakers
are out of phase, the low-
frequency sound waves will
cancel each other out,
normal THX operation, the
Phase switch should be set to
0 degrees so that the sub-
woofer is operating in phase
with the main speakers. This
should produce a smooth
frequency response up to
80Hz. In rare cases when the
subwoofer is placed more
than 25 feet away from the
main speakers, or where the
subwoofer is not being used
with a THX-certified receiver,
or processor, and speakers,
the 180-degree position may
provide a smoother frequency
response.
Listen to your HTPS-400
subwoofer and main speakers
with the switch in the “0°”
position, then listen to the
same material with the switch
set to “180°”. Decide which
sounds better and leave the
switch in this position. Repeat
this procedure if you change
the location of the subwoofer.

The HTPS-400 provides a
convenient phase switch that
allows you to remedy this
situation without relocating
the speakers or changing any
speaker connections. In
TROUBLES HOOTING
If there is no output from the
subwoofer:
If there is no (or low) bass
output:
If you are hearing midrange
frequencies (such as vocals)
through the subwoofer:
• Make sure the system is on
and a source is playing.
• Make sure the HTPS-400 is
plugged into an active outlet
and the power switch is in
either the “Auto” or “On”
position.
• Make sure that the sub-
woofer is plugged into a live
electrical outlet and the
power switch is in either the
“Auto” or “On” position.
• Adjust the “Crossover
Frequency.”
• When using the THX mode,
make sure the subwoofer
crossover is activated on your
processor/receiver.
• When using the Normal
Mode, adjust the “Crossover
Frequency” to a lower
frequency.
• If you are using a THX-
certified processor/receiver,
make sure the THX/Normal
switch is set to “THX.”
• Adjust the “Output Level”
(Gain) control.
• Change the setting on the
Phase switch.
• If you are not using a THX-
certified processor/receiver,
make sure the THX/Normal
switch is set to “Normal.”
• Adjust the “Output Level”
(Gain) control.
• If you are not using a THX-
certified processor/receiver,
make sure that you have
configured your processor/
receiver so that the sub-
woofer/LFE output is on.
• Review proper operation of
your receiver/amplifier.
• Check all wires and make
sure they are properly
connected. Make sure none
of the wires are frayed, cut or
punctured.
• If you are not using a THX-
certified processor/receiver,
make sure that you have
configured your processor/
receiver so that the subwoofer/
LFE output is on.
