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 or punctured.

If the system plays at low volumes but shuts off as volume is increased:

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.

If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier.

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.
