Svenska Nederlands Français Italiano Deutsch Español English
System doesn’t turn on Make sure the Acoustimass ® module power cord is inserted securely into the AC (mains) power outlet
and into the power connector on the Acoustimass module.
Be sure to press a source button (CD DVD, CBL SAT, etc.) on the 3 2 1 ® remote.
Unplug the power cord for 60 seconds, then plug it in again. This allows the unit to reset itself after a
power surge or power interruption.
For a 230-240V system (used typically in Europe), make sure the power switch on the Acoustimass
module is turned on ( I ).
For a dual voltage 3 2 1 system only, make sure the voltage setting is correct for your region. If it is set
to 115V, the system may not operate in a 230V region.
CAUTION: Do not change the voltage switch from 230V to 115V unless you are certain it is appropriate for
the power supply in your location.
No sound Increase the volume.
Check to see if MUTE is lit on the display. If it is, press the Mute button on the remote control to unmute
the sound.
Be sure that you have pressed the correct source button (CD DVD, CBL SAT, etc.) on the 3 2 1 remote.
Check the audio connections for the component you want to play.
Connect the FM and AM antennas.
Make sure that the cable between the Acoustimass module and the media center is connected securely.
Check connections between the speakers and the Acoustimass module.
Turn off the media center for 60 seconds, then on again, to restore communication between the media
center and the speakers.
Sound is distorted Make sure speaker cables are not damaged and the connections are secure.
Reduce the volume level on the external device playing through the 3 2 1 system speakers.
Sound is marred by a loud
hum or buzz
Try plugging your system into a different AC outlet.
Check to see if your media center and its audio input cable are within 3 ft (1 m) of any other electronic or
electrical device. Some examples are a TV, cable box, VCR, wireless internet router, dimmer switches,
blinking lights, or microwaves.
Move the media center farther away and notice if the humming still occurs.
