1. Speaker Level Outputs - Connect the Left, Center
and Right speakers to these connectors.
2. Speaker 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.)
3. Line 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.
4. Auto/On Switch - This switch allows you to set the
Mode of the Amplifier. Turn the switch to Auto to
cause it to Auto-matically turn on when it receives a
signal and Auto-matically turn off after twenty minutes
without a signal. If this switch is left “On”, the
subwoofer will always be ON when the power switch
is turned On, regardless of input signal.
5. Subwoofer Level - This knob controls the volume
level of the SUB125.
6. LED - Red & Green. The LEDs indicate the Mode
status that the subwoofer is in. When the SUB125 is
turned OFF neither LED will be lit. The Green LED
will light when the SUB125 is ON and receiving a
signal. The Red LED will light when the amplifier has
not received a signal for twenty minutes. The
subwoofer will turn on when your receiver/amplifier
begins playing again.
7. Power Switch - This the master power switch. Use it
(in Off mode) to disconnect power to the amplifier.
8. Fuse - Use only same type of fuses. For the U.S.
120V version use only a 2A 250V fuse. For the
European 230V version use only a 1A fuse.
9. AC Cord

General Function
UUT = Unit Under Test
1. Connect both right and left line level inputs (RCA) to
signal generator and UUT. Use Y-cable if necessary
from mono source. VOLUME control should be full
counterclockwise.
2. Turn on generator, adjust to 200mV, 50 Hz.
3. Plug in UUT; red LED should be ON. Turn VOLUME
control full clockwise.
4. LED should turn Green; immediate bass response should
be heard and felt from port tube opening.
5. Turn off generator, turn VOLUME control fully
counterclockwise, disconnect RCA cables.
6. Connect one pair of speaker cables to both high level
input terminals on UUT. Cables should be connected to
an integrated amplifier fed by the signal generator.
7. Turn on generator and adjust so that speaker level output is 3.0V, 50 Hz. Turn VOLUME control full clockwise.
8. Green LED should light, 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.
Driver Function
1. Remove driver from cabinet; detach + and - wire clips.
2. Check DC resistance of driver; it should be 3.3 ohms.
3. Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier fed by
a signal generator. Turn on generator and adjust so that speaker level output is 5.0V.
4. Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.

SIMPLE TROUBLESHOOTING
If there is no sound from any of the
speakers, check the following:
•Receiver/amplifier is on and a source is playing.
•Powered subwoofer is plugged in and is either in the “On”
or “Auto”position.
•Check all wires and connections between receiver/
amplifier and speakers. Make sure all wires are connected.
Make sure none of the speaker wires are frayed, cut or
punctured.
•Review proper operation of your receiver/amplifier. If there
is no sound coming from one speaker, check the following:
•Check the “Balance”control on your receiver/amplifier.
If the system plays at low volumes but
shuts off as volume is increased, check the
following:
•Check all wires and con-nections between receiver/
amplifier and speakers. Make sure all wires are connected.
Make sure none of the speaker wires are frayed, cut or
punctured.
•If more than one pair of main speakers is being used,
check the minimum impedance requirements of your
receiver/amplifier.
If there is low bass output, check the
following:
•Make sure the connections to the left and right “Speaker
Inputs”have the correct polarity (+ and –).
•Powered subwoofer is plugged in and is either in the “On”
or “Auto”position.
If there is no sound from the surround
speakers, check the following:
•Check all wires and connections between receiver/
amplifier and speakers. Make sure all wires are connected.
Make sure none of the speaker wires are frayed, cut or
punctured.
•Review proper operation of your receiver/amplifier and its
surround sound features.
•Receiver mode must be in Dolby Pro logic, Dolby Digital,
or any other mode that creates a surround-sound effect.
Even under normal operation, when viewing movies and
television, surround sound is not present at all times at a
high volume - only when the program has chosen to send
information there.
