BEFORE THIS AMPLIFIER IS PLUGGED IN, make sure its rated voltage corresponds to the voltage of the AC power
source to be employed. Failure to use the correct voltage could cause damage to the amplifier when the AC power cable
is plugged in. Do not exceed the rated voltage by more than 10%; operation below 90% will degrade performance or
cause the unit to shut off.
WHEN SERVICING THIS AMPLIFIER:
1. Do not touch the metal frame of the woofer (if removed from the cabinet) when driving the amplifier at high power
levels. In the unlikely event that the output devices in the amplifier fail and present an open circuit during their operation,
AND the driver voice coil was to come in contact with the motor assembly, hazardous voltage could be present at the
woofer frame.
2. When 120/230v-based test equipment is connected to the amplifier in any way, use of a 1000W isolation transformer
(Stancor model GIS-1000 or similar) on the subwoofer is necessary for safety; in addition, an isolator plug, (a
three-to-one pin adapter sometimes called a “cheater plug”) should be used on the power cord plug of the test equipment
being used.

CONTROLS AND CONNECTIONS
1. Equalizer - The EQ optimizes subwoofer performance
for audio or video playback.
2. Crossover Frequency - The crossover frequency
knob determines the highest frequency your
subwoofer will reproduce. It allows a seamless
transition from the subwoofer to the satellite
speakers.
3. Phase - The phase switch is used to adjust the
relative polarity of the subwoofer. When the phase
switch is up, the phase is normal - when the switch
is depressed, the subwoofer is 180 degrees out of
phase.
4. Gain - This knob controls the volume status of the
subwoofer.
5. Input - The Input switches between the normal
line/speaker inputs and the direct-LFE input.
6. Highpass Output - This toggle switch controls the
roll-off frequency of the high pass filter, the LOW
LEVEL OUT connectors, #7.
7. Low Level output - These RCA output jacks are used
when it is desirable to limit the low frequencies to your
main receiver/power amplifier; see more on page 6
8. Low Level Input - Main RCA input jacks, recommend
hook-up method. When using a single LFE (Low
Frequency Effects) cable from a Dolby Digital
receiver/processor, use either left or right RCA jack.
9. Fuse - Use only same type of fuses. Use a 4A 250v
MDL Slo-Blo fuse for the 120v model, and a 2A
250v MDL Slo-Blo fuse for the 230v model.
10. AC Plug - Plug in the AC line cord in here.
11. High Level Inputs - These High Level Inputs are for
receivers that do not have line-level “pre-amp out”
or “subwoofer out”jacks. When a pair of main or
satellite speakers are attached to the OUTPUT
terminals, they are driven the full range of
frequencies as generated by the music source
(receiver, amplifier, etc.)
12. LED - This LED turns green when the HPS250 is
receiving power (is turned on) and is receiving a
signal.
13. Main - This button is the master power switch.

If your receiver/processor does not have subwoofer
outputs for the left and right channels:
If your receiver/processor has subwoofer outputs for
the left and right channels:
NOTE: Some receivers have a single subwoofer
output (do not confuse this with a single LFE output as
described on the next page). In that case, it is
recommended that you use a Y connector (not
included) to maximize performance.

RECEIVER/PROCESSOR

If you have a Dolby Digital or DTSÒ
receiver/processor with a low-frequency-effect
(LFE) output:
NOTE: In this case, you do not need to use a Y
connector: Simply connect the LFE output on your
receiver/processor to either the left or right input
on the subwoofer:
If your receiver/amplifier has preamp output jacks
and main input jacks for the left and right
channels or you have a separate
preamp/processor and power amplifier:
This method of hookup can offer the highest level
of performance for your complete loudspeaker
system. Your subwoofer incorporates an
adjustable high-pass crossover in addition to a
variable low-pass crossover. When hooked up as
shown on the right, the subwoofer will limit the
low-frequency information that is returned to your
receiver/amplifier. Your receiver/amplifier does
not need to waste valuable power reproducing
the low frequencies. In addition, since no
low-frequency information is being sent to your
main loudspeakers, they are able to reproduce
mid and high frequencies with greater clarity.

OPERATION
Setting the Controls
1. Initially set the HPS500’s Gain control to the “O”
position.
2. Initially set the HPS500’s Crossover control to the
100Hz position.
Turning the Power On
3. Plug your HPS500’s AC cord into a wall outlet. Do not
use the outlets on the back of the receiver.
4. Turn on your HPS500 sub by pressing the power button
on the center of the front panel.
5. Turn on your entire audio system and start a CD or
movie sound track at a moderate level.
Adjusting the Gain Control
6. Turn your HPS500’s Gain control (page 4, #4) up to the
“5”position (half way). If no sound emanates from the
subwoofer, check the AC-line cord and input cables. Are
the connectors on the cables making proper contact? Is the
AC plug connected to a “live”receptacle? Has the power
button been pressed to the “on”position? (Note: A green
indicator on the front panel will light when the power is on.)
Once you have confirmed that the subwoofer is active,
proceed by playing a CD, record or cassette. Use a
selection that has ample bass information.
7. Set the overall volume control of the preamplifier or
stereo to a comfortable level. Adjust the subwoofer’s Gain
control (page 4, #4) until you obtain a pleasing blend of
bass. Bass response should not overpower the room but
rather be adjusted so there is a harmonious blend across
the entire musical range. Many users have a tendency to
set the subwoofer volume too loud, adhering to the belief
that a subwoofer is there to produce lots of bass. This is
not entirely true. A subwoofer is there to enhance bass,
extending the response of the entire system so the bass
can be felt as well as heard. However, overall balance
must be maintained or the music will not sound natural. An
experienced listener will set the volume of the subwoofer
so its impact on bass response is always there but never
obtrusive.
Crossover Adjustments
8. Crossover Control (page 4, #2) –The Low-Pass
control determines the highest frequency at which the
subwoofer reproduces sounds. If your main speakers can
comfortably reproduce some low-frequency sounds, set
this control to a lower frequency setting, between 50Hz –
100Hz. This will concentrate the subwoofer’s efforts on
the ultradeep bass sounds required by today’s films and
music. If you are using smaller bookshelf speakers that
do not extend to the lower bass frequencies, set the
low-pass crossover control to a higher setting, between
120Hz –150Hz.
The Phase Control
9. The Phase Control (page 4, #3) determines whether
the subwoofer speaker’s piston-like action moves in and
out with the main speakers, 0°, or opposite the main
speakers, 180°. Proper phase adjustment depends on
several variables such as room size, subwoofer
placement and listener position. Adjust the phase switch
to maximize bass output at the listening position.
10. The EQ switch, located on the front panel, optimizes
the subwoofer’s performance for both movie and music
listening. When in the “Video”position, a special EQ
circuit is activated, enhancing low frequencies by
approximately 3dB at 32Hz and delivering the full impact
and excitement of today’s movie soundtracks. When in
the “Audio”position, the subwoofer provides the accurate
and linear frequency response that is ideal when a natural
tonal balance is desired for music listening.
11. Remember: every system, room and listener is
different. There are not necessarily any right or wrong
settings; any setting you choose will result in excellent
performance. Should you decide to fine-tune your system
for optimum performance, be patient and trust your ears.
It will be worth the effort involved to fully “tweak”your
system.

1. DO NOT ATTEMPT TO PRY THE GRILLE (#10) OUT
OF ITS RECESS.
2. Lay the subwoofer on its side on a padded surface.
3. Remove the (4) rubber foot plugs (#15).
4. Remove the (4) 1”foot screws (#16), remove all four
feet.
5. Remove all (12) 2”exposed bottom panel screws
(#13).
6. Pull the bottom panel (#12) out of the cabinet - one
way to accomplish this is to partially screw one of
the 2”screws back into a threaded “foot”hole and pull
on the screw. Lift the bottom panel & woofer (#9) out
of the cabinet.
DISASSEMBLY PROCEDURES
WHEN SERVICING THIS AMPLIFIER:
1. Do not touch the metal frame of the woofer (if removed from the cabinet) when driving the amplifier at high power
levels. In the unlikely event that the output devices in the amplifier fail and present an open circuit during their operation,
AND the driver voice coil was to come in contact with the motor assembly, hazardous voltage could be present at the
woofer frame.
2. When 120/230v-based test equipment is connected to the amplifier in any way, use of a 1000W isolation transformer
(Stancor model GIS-1000 or similar) on the subwoofer is necessary for safety; in addition, an isolator plug, (a
three-to-one pin adapter sometimes called a “cheater plug”) should be used on the power cord plug of the test equipment
being used.
