Problem What to do
System does not function at all • Make sure the receiver and powered Acoustimass module are plugged into an operating AC outlet and that the
receiver is turned on.
• Be sure to select an audio source on the receiver (Blu-ray or DVD player, CBL/SAT box, gaming system, etc.).
No sound • Increase the volume.
• Disconnect any headphones.
• Check the speaker connections at the bass module, reciever, and speakers.
• Make sure that both the powered Acoustimass module and the receiver are plugged in.
• For digital sound, be sure an HDMI, coaxial or optical cable connects the digital output of the audio source
with the digital input on your receiver.
• Be sure the audio source selected is correct. For example, select DVD audio on your receiver to hear the
DVD sound.

• If you are using the Dolby Pro-Logic mode on your receiver, make sure surround sound is turned on.
• Be sure the source material (Blu-ray
™
or DVD player, CBL/SAT box, gaming system, etc.) is Dolby Digital encoded.
• Be sure your receiver is processing a signal from a stereo TV, laserdisc, Blu-ray player or DVD player, or other
surround sound source.
• If you are using digital programming, verify that the settings are correct at the receiver.
No bass • Be sure the speaker connections from the receiver to the amplifier are in the correct phase, red-collared wire to red
connector (+ to + and – to –).

Not enough or too much bass • Move your Acoustimass module closer to a wall or corner to increase bass. Move it farther from a wall or corner to
decrease bass.
