USING YOUR SPEAKER SYSTEM

Balancing tone for the sound you like

The acoustics of your room affects the sound you hear there. Upholstered furniture, carpets, and drapes absorb sound, which can muffle the treble (high frequencies). Bare floors, walls, and furniture have the opposite effect and can make the treble sound shrill.

A bass compensation control on the Acoustimass® module enables you to balance the tones you hear.

There are two ways to adjust the bass:

•Turn the control clockwise to increase or counterclockwise to decrease bass.

•Reposition the module. To increase bass, turn the front of the module toward a wall or other nearby surface. To decrease bass, aim the front from the wall.

	originally unheard speaker, this speaker may be
	the cause. Contact Bose® Customer Service.

	one that previously performed) a defective output

	Try a different source.
