Troubleshooting Problem No sound from ­speakers Sound from one speaker only Bass/treble is weak Static/noise from speaker What to do • Ensure the speaker wires did not disconnect from the speakers or the ­­ receiver/amplifier. • Check the settings on your receiver/amplifier. Refer to the receiver/amplifier owner's guide for instructions on settings. • If other stereo speakers are connected to a second set of audio outputs on your receiver/ amplifier, select the proper A or B speaker setting to match the A or B outputs connected to your ­speakers. • Center the balance control on your receiver/­ amplifier. • Ensure no wires from the positive and ­negative terminals on the receiver/amplifier are touching. • Disconnect the speaker wire from the receiver/­ amplifier ­channel and reconnect it to a different channel. • Check that no wires from the positive and ­negative terminals are touching where the speaker wire connects to the speaker. • Disconnect the speaker wire from the speaker and ­reconnect it to another speaker. If this speaker works, your speaker needs to be serviced. Refer to the contact sheet in the carton. • Replace and re-install the speaker wire if these ­troubleshooting steps do not solve the problem. • Adjust the tonal balance setting on your receiver/amplifier. • Ensure there are no gaps between the speaker frame and the wall surface. • Switch the wires connected to the positive and ­negative terminals on the receiver/amplifier. • Disconnect the speaker wire from the receiver/­ amplifier ­channel and reconnect it to a different channel. • Ensure the wires are in good condition, are firmly connected to the speaker and receiver/amplifier and are not touching across terminals. • Connect the music source to the receiver/amplifier properly. • See "Sound from one speaker only".
