BEFORE THIS AMPLIFIER IS PLUGGED IN, make sure its rated voltage corresponds to the voltage of the A
power source to be employed. Failure to use the correct voltage could cause damage to the amplifier when the A
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 SERVI ING 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 THEIR FUNCTION
1. Gain - This knob controls the volume status of the
subwoofer.
2. 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.
3. C ossove F equency - The crossover frequency
knob determines the highest frequency your
subwoofer will reproduce. It allows a seamless
transition from the subwoofer to the satellite
speakers.
4. LED - This LED turns green when the HPS250 is
receiving power (is turned on) and is receiving a
signal.
5. Main - This button is the master power switch.
6. Low Level Input - These left and right Line Level
Inputs are normally used when the receiver/
processor has line-level “pre-amp out ” or
“subwoofer out” jacks. If a single cable mono
or subwoofer source is connected to the HPS250, a
Y-cable must be connected to the subwoofer for
full output.
7. Fuse - Use only same type of fuses. Use a 2A 250v
MDL Slo-Blo fuse for the 120v model, and a 1A
250v MDL Slo-Blo fuse for the 230v model.
8. AC Plug - Plug in the A line cord in here.
9. 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.)

DISASSEMBLY PROCEDURES
Amplifie Removal
1. Lay the subwoofer on its side on a padded surface,
amplifier facing upwards.
2. Locate and remove the (2) Allen head screws (#2) at
the bottom of the plastic cover with a 3/32” wrench.
3. Slide the amplifier straight down until it clears the slotted
brackets (#4) & (#5); pull away from the cabinet and
expose for servicing without further disconnection.
4. To remove individual boards if desired, remove Philips
screws and all relevant molex or other connectors.
5. Wires threading through the cabinet, glued in place,
should be left intact under all circumstances.
Woofe Removal
1. DO NOT ATTEMPT TO PRY THE GRILLE (#10) OUT
OF ITS RE ESS.
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 (8) 2” expose 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.
7. Unplug both woofer terminals; remove all (8) 3/4” screws
(#11).
Bias Test
1. Remove and expose amplifier assembly by following
instructions above. All connectors must remain intact.
2. Locate and disconnect the D+ connector on the main
board; insert a D Ammeter set to a low range between
the connectors.
3. Locate and adjust R13 and R28 potentiometers on the
main board near the connector to maximum W.
4. onnect power cord, turn on power switch; verify initial
D current is less than 1.5mA.
5. Adjust R28 W slowly until meter reads 5 mA.
6. Now adjust R13 W slowly until meter reads 10 mA.
7. Turn power OFF; disconnect Ammeter and re-connect
D+ terminal.
Audio Test
1. Remove the woofer by following instructions above;
replace with a 20 ohm 100 watt resistive load.
2. onnect a voltmeter (Wavetek DM25XT or similar) and
oscilloscope to the amplifier output terminals, plus the
load.
3. Adjust the Gain control to minimum. Frequency should
be set to maximum. (Pahse is irrelevant); there is no
input signal for this test.
4. Turn on the unit; Observe voltage on oscilloscope and
rotate controls; A noise should be less than 8 mV.
5. Adjust the Gain control to minimum; Frequency should
be set to maximum. (Phase is irrelevant) onnect a
signal generator to the Left Low Level (R A) input; only
one cable is necessary; set the generator to 60Hz,
800mV.
TEST PROCEDURE 1
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.

TEST PROCEDURE 2
(Note: A high gain amplifier of at least a 100 watt rating is recommended for this test
Gene al Function
UUT = Unit Under Test
1. onnect both right and left line level inputs (R A) to signal generator and UUT. Use Y-cable if necessary from
mono source. GAIN control should be full counterclockwise.
2. Turn on generator, adjust to 100mV, 50 Hz.
3. Plug in power cord to UUT; push the main A power button ON. Green LED should be lit.
4. Turn GAIN control full clockwise; immediate bass response should be heard and felt from port tube opening.
5. Turn off generator, turn GAIN control fully counterclockwise, disconnect R A cables.
6. onnect one pair of speaker cables to either pair (R) or (L) input terminal on UUT. ables should be connected to
an integrated amplifier fed by the signal generator.
7. Turn on generator and adjust so that speaker level output is 2.0V, 50 Hz.
8. Turn GAIN control full clockwise; immediate bass response should be heard and felt from the port tube opening.
Sweep Function
1. Follow steps 1-4 above, using a sweep generator as a signal source.
2. Sweep generator from 20Hz to 300Hz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or any
other noises. If any unusual noises are heard, remove driver and test.
D ive Function
1. Remove driver from cabinet following instructions on page 5.
2. heck D resistance of driver; it should be 21 ohms +/-10%.
3. onnect a pair of speaker cables to driver terminals. ables should be connected to an integrated amplifier fed by
a signal generator. Turn on generator and adjust so that speaker level output is 30.0V.
4. Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
