Speaker Outputs

RIGHT LEFT

Speakers and electronics terminals have corresponding (+) and

(–) terminals. It is important to connect both speakers identi-

cally: (+) on the speaker to (+) on the amplifier and (–) on the

speaker to (–) on the amplifier. Wiring “out of phase” results in

thin sound, weak bass and a poor stereo image.

If there is no sound from

any of the speakers, check

the following:

• Receiver/amplifier is on and

a source is playing.

• 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.

• Check all wires and connec-

tions between receiver/

amplifier and speakers.

• Make sure all wires are

connected. Make sure none of

the speaker wires are frayed,

cut or punctured.

If the system plays at low

volumes but shuts off as

volume is increased, check

the following:

• Check all wires and connec-

tions between receiver/

amplifier and speakers.

• Make sure all wires are con-

nected. 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 imped-

ance requirements of your

receiver/amplifier.

If there is low bass output,

check the following:

• Make sure the polarities

(+ and –) of the left and

right “Speaker Inputs” are

connected properly.

If there is no sound from

the center speaker, check

the following:

• Make sure that your receiver’s

Center Channel Mode is in the

”normal“ or ”wide“ position. If

it is in the ”phantom“ position,

the center speaker will not play.

• Check all connections

between processor/amplifier

and the center speaker.
