IF THERE IS NO SOUND FROM ANY OF THE SPEAKERS:

speakers. Make sure all wires are connected. Make sure none of the
speaker wires are frayed, cut, punctured or touching each other.
• Review proper operation of your receiver/amplifier.
IF THERE IS NO SOUND COMING FROM ONE SPEAKER:
• Check the "Balance" control on your receiver/amplifier.
• 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, punctured or touching each other.
IF THERE IS LOW (OR NO) BASS OUTPUT:
• Make sure the connections to the left and right "Speaker Inputs" have
the correct polarity (+ and –).

rear speakers have been configured as "LARGE." See your receiver/
processorʼs ownerʼs manual for further information on correct speaker
configuration in Dolby Digital, DTS and other surround sound modes.

speaker wires are frayed, cut , punctured or touching each other.
• If more than one pair of main speakers is being used, check the
minimum-impedance requirements of your receiver/amplifier.
