One speaker 
still does not 
play

• Disconnect the wires from that speaker and the amplifier. Disconnect the other cable 

from its speaker, and connect that end of the cable to the speaker that does not play. 
If the speaker still does not play, the problem is in the speaker. If the speaker now 
plays, continue checking for the source of the problem.

• Disconnect the same cable from the amplifier. Connect it to the other outputs on the 

amplifier. If the speaker plays, the problem is in the original cable that was connected 
to that speaker. If the speaker does not play, the problem is in that channel of the 
amplifier.

Right and left 
stereo channels 
are heard on the 
wrong speak-
ers.

• Check the speaker cable connections to be sure the cable connected to the 

SPEAKER OUTPUTS L at the amplifier are connected at the other end to the speaker 
on the left in your listening area.

• Check the speaker cable connections to be sure the cable connected to the 

SPEAKER OUTPUTS R at the amplifier are connected at the other end to the speaker 
on the right in your listening area.

Bass or treble is 
weak

• Check the speaker wire connections. Make sure the wires are connected +  to + and 

– to –. 

• See “Connecting speakers to your Lifestyle

®

 stereo amplifier” on page 14.

Interference

• Make sure the speaker wires are firmly inserted in the terminals on the back of the 

speaker and on the amplifier rear panel. Check to be sure no wires are touching 
across terminals. 

• See “Connecting speakers to your Lifestyle

®

 stereo amplifier” on page 14.

Remote does 
not adjust the 
volume

• Be sure the 1/8” mini-plug is firmly inserted in the SYSTEM CONTROL 2 jack.

• If you are using an RC-20 or RC-5 remote control, make sure the remote control 

switch settings are correct.

Volume 
suddenly 
decreases

• Lower the volume setting to see if the level returns to normal. If so, the sudden loss of 

volume was an intentional action of the amplifier’s overload protection feature. This 
engages automatically if the volume is set too high and is overdriving the speakers. 
Choosing a lower setting should ensure continuous, even volume.

Zone 2 does not 
work at all

• If you are using a Lifestyle

®

 DVD system, the stereo amplifier will not work unless 

“Zone 2 Protocol” in the system settings menu is set to “Legacy”. For more informa-
tion, consult your Lifestyle

®

 DVD system’s owners guide.
