Справочник Пользователя для Bose multimedia speakers Companion 3 Series II

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.

The speaker system does not 
play

• Make sure all connections are secure. (See “Making 

connections” on page 8.)

• Check your speaker wires for damage or frays, which 

can cause an open or short circuit.

• Be sure that the sound source is plugged in and 



playing at an audible volume.

• Make sure the power is on and the system is not 

muted. The LED on the control pod should be green 
when unmuted.

• If using a PC, check your sound card settings to make 

sure the “Digital output only” setting is turned OFF. 
This setting is typically found in the Options menu of 
the volume control icon. This icon is usually located in 
the lower right-hand corner of the Windows desktop.

The speaker system sound



seems distorted

• Decrease the volume of the sound source and 

increase the speaker system volume using the control 
pod.

One speaker does not perform 
or sounds distorted

• Check connections from the speakers, control pod, 

and computer to the Acoustimass

®

 module. (See

“Making connections” on page 8.)

• Be sure the cable from the unheard speaker is firmly 

inserted in the proper To Speaker jack on the module.

• Switch the connection of both speakers to jacks on 

the rear of the Acoustimass module.

If this does not resolve the problem for the 



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

If the problem switches to the other speaker (the 
one that previously performed) a defective output 
channel on the sound source may be the cause. 
Try a different source.

If this does not resolve the problem, the Acousti-
