disconnect from the speakers or the receiver/

•  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/

to match the A or B outputs connected to your 
 speakers.

speaker and indicates where to make the speaker hole in the 
wallboard.
