JBL ATX 30 (220-240V) Owner's Manual - Troubleshooting

English

TROUBLESHOOTING

If there is no sound from any

of the speakers:

• Check that receiver/ampli-

fier is on and that a source is

playing.

• Review proper operation of

your receiver/amplifier.

If there is no sound coming

from one speaker:

• Check the “Balance” control

on your receiver/amplifier.

• Check all wires and connec-

tions between receiver/ ampli-

fier and speakers.

• Make sure no wires are

touching other wires or 

terminals and creating a short

circuit.

• Make sure all wires are con-

nected. Make sure none of the

speaker wires are frayed, cut

or punctured.

• In Dolby* Digital or DTS®

modes, make sure that the

receiver/processor is config-

ured so that the speaker in

question is enabled.

• Turn off all electronics and

switch the speaker in question

with one of the other speakers

that is working correctly. Turn

everything back on, and deter-

mine whether the problem has

followed the speaker, or has

remained in the same channel.

If the problem is in the same

channel, the source of the

problem is most likely with

your receiver or amplifier, and

you should consult the

owner’s manual for that prod-

uct for further information. If

the problem has followed the

speaker, consult your dealer

for further assistance or, if that

is not possible, visit 

www.jbl.com 

for further information.

If the system plays at low vol-

umes but shuts off as volume

is increased:

• Check all wires and con-

nections between receiver/

amplifier and speakers.

• Make sure all wires are con-

nected. Make sure none of the

speaker wires are frayed, cut

or punctured.

• If more than one pair of main

speakers is being used, check

the minimum impedance

requirements of your receiver/

amplifier.

If there is no (or low) bass

output:

• Make sure the polarities 

(+ and –) of the left and right

“Speaker Inputs” are 

connected properly.

• If your system includes a

powered subwoofer, make

sure it is connected correctly,

plugged into an active AC out-

let and turned on. See the

owner's guide for your sub-

woofer for more information.

• If your system does not

include a powered subwoofer,

consider adding one for use

with digital “.1” surround for-

mats.

If there is no sound from 

the surround speakers:

• Check all wires and connec-

tions between receiver/ampli-

fier and speakers. Make sure

all wires are connected. Make

sure none of the speaker

wires are frayed, cut or punc-

tured.

• Review proper operation of

your receiver/amplifier and its

surround sound features.

• Make sure the movie or TV

show you are watching is

recorded in a surround sound

mode. If it is not, check to see

whether your receiver/ampli-

fier has other surround modes

you may use.

• In Dolby Digital or DTS

modes, make sure your

receiver/processor is config-

ured so that the surround

speakers are enabled.

• If you are using both side

surround and back surround

speakers, make sure that your

receiver/processor is config-

ured for 6.1/7.1 operation.

• Review the operation of your

DVD player and the jacket of

your DVD to make sure that

the DVD features the desired

Dolby Digital or DTS mode,

and that you have properly

selected that mode using both

the DVD player’s menu and the

DVD disc’s menu.
