If you are experiencing problems with your 701

®

speakers:

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

®

dealer to arrange for service. Refer to the enclosed list for

correct phone numbers.

Problem

Possible cause

How to find out

Solution

One speaker

doesn’t play or

sounds distorted

Defective amplifier

or receiver channel,

or defective speaker

Switch the LEFT

and RIGHT input

connections on the

back of your left

main speaker.

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.

Both speakers do

not play, or sound

distorted

Defective amplifier

or receiver

Disconnect the

amplifier or receiver

from the speakers.

Reconnect the

speakers to another

amplifier or receiver

that is working

properly.

High sound volume

drops suddenly

The automatic pro-

tection circuit has

activated to protect

the speakers from

electrical stress or

overload

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-

tronic stress and

overload.

Return the volume

to a reasonable level

and avoid extremely

high volume set-

tings.

No bass

Left main speaker is

not plugged in or

the power switch is

not turned on

Check all connec-

tions – especially

AC power.

Be sure all connec-

tions are made and

the amplifier/

receiver is on.

Weak bass

Subwoofer/LFE

level or bass level

set too low

Check knob posi-

tions on the left

main speaker.

Check receiver set-

tings.

Adjust knob posi-

tions to desired set-

ting.

Distorted sound or

diminished sound

quality

Out-of-phase wiring

Check connections.

They should be in

phase (+ to + and

– to –).

Adjust connections,

if they are out of

phase.
