Troubleshooting

Problem What to do

Distorted or no sound • Disconnect the ampliﬁer or receiver from the system, and reconnect the Acoustimass

module to another ampliﬁer

or receiver that is working properly. If the system now works, the problem is in your ampliﬁer or receiver.

• Power off the ampliﬁer or receiver and check all the connections between the speakers, the module, and ampliﬁer

or receiver.

• Refer to your ampliﬁer or receiver’s owner’s guide for more troubleshooting information.

• See “Checking your receiver or ampliﬁer’s speaker channels”.

Checking your receiver or ampliﬁer’s speaker channels

If one of the speakers does not play or sounds distorted, your ampliﬁer or receiver’s speaker channel may be defective.

1. Disconnect both speaker cables from the ampliﬁer or receiver.

2. Reconnect the cable from the Acoustimass

module’s L INPUTS to the ampliﬁer or receiver’s right speaker terminals.

3. Disconnect both speaker cables from the ampliﬁer or receiver. Reconnect the cable from the Acoustimass

module’s L INPUTS to

the ampliﬁer or receiver’s right speaker terminals.

4. Set the ampliﬁer or receiver’s balance control all the way to the right and power it on. If the left speaker now plays properly, your

ampliﬁer or receiver’s left speaker channel may be defective.

5. Repeat to check your right speaker, reconnecting the cable from the module’s R INPUTS to the ampliﬁer or receiver’s left speaker

terminals.

CAUTION: DO NOT connect the other speaker to the potentially defective channel. If the channel is defective, it could damage your

Acoustimass system.

Cleaning

• Clean the surface of the system with a soft, dry cloth.

• Do not use any sprays near the system. Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia or

abrasives.

• Do not allow liquids to spill into any openings.
