What to do
• Make sure the power connector is plugged securely into the music center, the Acoustimass
module power cord is plugged securely into the module, and the power pack and power
cord are plugged into operating AC wall outlets.
• Be sure to select a source (CD, AM/FM, etc.).
• Unplug the music center power pack for a minute, then reconnect it. This allows the unit to
reset itself after a power surge or power interruption.
• Make sure the audio input cable is connected to the music center FIXED outputs, the black
connector is fully seated in the music center SYSTEM CONTROL 1 jack, and the multi-pin
connector is firmly seated in the Acoustimass module jack.
• Turn the music center off for ten seconds, then on again, to reestablish communication
between the music center and the speakers.
• Check the connections for any external components. Make sure to select the correct
source for the desired input.
• Check the speaker connections.
• Be sure the CD is placed correctly, label-side up, in the music center, and the cover is
closed.
• Increase the volume.
• Check to see if MUTE is lit in the display. Press the MUTE button on the remote to unmute
the sound.
• Disconnect any headphones.
• Connect the FM and AM antennas.
• Make sure that the center cube cable is connected at both ends.
• Select STEREO+CENTER (3-speaker) or SURROUND (5-speaker) mode.
• In STEREO+CENTER mode, press SURROUND
• Press and hold the STEREO+CENTER (3-speaker) mode key for 10 seconds to restore the
factory preset center volume setting.
