What to do

• Increase the volume.

• Disconnect any headphones.

• Check the speaker connections.

• Make sure that both the powered Acoustimass module and the receiver are plugged in.

• For digital sound, be sure a coaxial or optical cable connects the digital output of the

DVD player 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.

• Make sure the source material contains surround 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 (DVD, laser disc, or broadcast programming) is Dolby Digital

encoded.

• Be sure your receiver is processing a signal from a Hi-Fi VCR, stereo TV, laserdisc, or

DVD player, or other surround sound source.

• If you are using digital programming, verify that the settings are correct at the receiver.

• Be sure the speaker connections from the receiver to the amplifier are in the correct

phase, red collared wired to red jack (+ to +).

• Move your Acoustimass module closer to a wall or corner to increase bass. Move it !

farther from a wall or corner to decrease bass.

• Adjust the LFE level or Room Compensation control.

• Make sure your speaker wire is not damaged.

• Reduce the volume of external components connected to the receiver.
