for use depending on the type  
of surface the subwoofer will  
be placed on. Enclosed with  
this manual is a set of rubber  
self-adhesive feet for use on  
hard surfaces, such as wood  
or tile floors, and a set of  
spiked feet for use on  
carpeted surfaces. To install  
the feet, set the subwoofer  
gently on a padded surface  
with the bottom side up. If

is not designed for frequent  
removal, and cannot be  
readily removed with bare  
hands. If for some reason it  
becomes necessary to remove  
the grille, it should be pried off  
very carefully with a small, flat-

taking extra care not to  
perform as well as expected if  
you neglect to attach the feet.

OP ERATION  
The HTPS-400 contains a

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 switchs Off” position

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
