Cause

AC power is not getting to the

amplifier.

Fuse is blown or subwoofer

amplifier is not working.

Connection between 12" woofer

and sub amplifier is loose or not

connected.

12" woofer or sub amplifier is

faulty.

The subwoofer is not receiving a

signal.

Subwoofer amplifier may not

be not working. See solution to

troubleshoot.

Volume level on subwoofer or

receiver's subwoofer output is too

low.

Subwoofer is not placed correctly.

You used speaker level connections

and have mixed up the polarity of

the wires, thus shorting one chan-

nel of the main amplifier.

Solution

• Make sure the switch on the back of the sub is in the "ON"

position.

• Check that you are using the correct power cord and that

it is plugged in securely at both ends and make sure that the

AC outlet the subwoofer is plugged into is working. Try an-

other power cord.

• If you have determined you are using the correct power

cord, it is plugged in securely at both ends, and your AC outlet

has power but the LED is still not lighting up, check your fuse

(see #9, Page 5). If this does not correct the problem, your

amplifier needs service. Please contact BIC Tech Support.

• Unplug your subwoofer. Unscrew the outer screws on the

back of the sub amp. Wiggle the amp out and make sure

both (+) and (-) leads from the amp are securely connected

to the (+) and (-) leads on the woofer. If not, this will solve

the problem.

• Determine whether the woofer or amplifier

is defective.

Unplug your subwoofer. Unscrew the outer screws around

the woofer. Take the 12˝ woofer out of the cabinet and per-

form one of the testing steps below:

1) Touch the woofer's (+) and (-) terminals to the (+) and

(-) terminals on a 9-volt battery. If you hear a popping

noise, the woofer is good and the amp needs repair. If you

do not hear a popping noise, the woofer is bad.

2) Touch the woofer's (+) and (-) terminals to the (+) and

(-) leads of a speaker wire connected to a main channel of

your receiver. If the woofer plays fine, then the amp needs

repair. If it does not play, then the woofer is bad.

• Make sure your digital receiver is set to "SUB ON".

• Recheck the connections between the receiver and the sub-

woofer.

• Set the subwoofer level to a minimum. Use a different RCA

cable to hook the sub to a DVD players analog output or to

an MP3 player. Play some music and slowly turn the volume

up on the sub. If the sub plays, then the sub is fine and the

problem lies either in the subwoofer cable, the setting on

the receiver, or you have connected to the wrong jack on

the receiver. If still no sound, contact BIC Tech Support.

Increase the volume control located on the back of the sub-

woofer and the subwoofer level or LFE level on the receiver

or other source. It is best to set the level of the subwoofer

relative to the other speakers.

See "Placement" Page 3 of this manual.

• Correct the polarity of the speaker wires by matching the

(+) and (-) from the receiver/amplifier to the (+) and (-) of

the subwoofer's speaker level input.
