1. Turn off the ampliﬁer or receiver and check all the connections between the speakers,

ampliﬁer, or receiver.

2. Check your ampliﬁer or receiver owner's guide, since other components may be the

cause of the problem.

3. Use the chart below as troubleshooting guidelines. If this does not solve the problem,

contact your authorized Bose

correct phone numbers.

How to ﬁnd out

Switch the LEFT

and RIGHT input

connections on the

back of your left

main speaker.

Disconnect the

ampliﬁer or receiver

from the speakers.

Lower the volume. If

it returns to normal,

your speakers'

automatic protec-

tion circuit caused

the sudden drop.

This volume reduc-

tion protects the

speakers from elec-

overload.

Check all connec-

tions – especially

AC power.

Check knob posi-

tions on the left

Check receiver set-

tings.

They should be in

phase (+ to + and

Solution

If the previously

"broken" speaker

now plays properly,

and the other one

does not, one chan-

nel in the ampliﬁer

or receiver is proba-

bly defective. If the

original speaker still

does not play prop-

erly, call Bose or

your retailer to

arrange for service.

Reconnect the

speakers to another

ampliﬁer or receiver

that is working

properly.

Return the volume

to a reasonable level

and avoid extremely

high volume set-

tings.

Be sure all connec-

tions are made and

the ampliﬁer/

receiver is on.

Adjust knob posi-

tions to desired set-

ting.

Adjust connections,

if they are out of

phase.
