Maintaining Your Acoustimass® 15 Speakers

Troubleshooting

If you have a problem with your Acoustimass 15 speakers, turn off your sound source and try the solutions below. If you still have a problem, contact your Bose® dealer to arrange for service. To contact Bose directly, refer to the inside back cover of this guide.

Problem		What to do
System does not function at all	•	Make sure the receiver and Powered Acoustimass module are plugged
		into an operating AC wall outlet and that the units are turned on.
	• Be sure to select a source at the receiver (video, CD, DVD, tuner).
No sound	•	Check the speaker connections.
	• Turn the Powered Acoustimass module ON.
	• 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 and player for DVD sound.
	•	Disconnect any headphones.
	•	Increase the volume.
No sound from cube arrays	•	Be sure the Powered Acoustimass module is plugged in and turned on.
Sound is distorted	•	Make sure speaker wire is not damaged.
	• Reduce the volume of external components connected to the receiver.
No bass	•	Make sure the speaker connections at the receiver or amplifier are correct
		(+ to + and – to –).
Not enough or too much bass	•	Move the Powered Acoustimass module closer to a wall or corner to
		increase bass. Move it farther away from a wall or corner to decrease bass.
	• Adjust the LFE level control.
No surround-sound	•	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
		the Dolby Pro-Logic mode, check that surround-sound is turned ON. If
		you are using Digital programming, verify that the settings are correct at the
		receiver. Be sure the source material (DVD, laser disc, or broadcast pro-
		gramming) is Dolby Digital encoded.

Cleaning the speakers

The cabinets of your Acoustimass 15 speaker system may be cleaned with a soft damp cloth. Do not use any sprays near the system or allow liquids to spill into any openings. Also, do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives.

The grille assemblies on the cube arrays may be carefully vacuumed, if necessary. Please note that the drivers are located directly behind the grille cloth, and are easily damaged if reasonable care is not taken.
