Using Your Acoustimass® 10 Series II Speaker System
For realistic home theater sound
Each speaker produces only the sound directed to it by the steering logic in your surround-
sound receiver. During a surround-sound program the front and center speakers will emit
sound almost constantly, while the surround speakers may be silent for periods of time.
Setting your Dolby Pro-Logic receiver
You must set the volume levels for the front, center, and surround speakers at your receiver.
You can adjust these levels at the receiver or with the remote control. Your receiver may have
a
test tone
to help you set volume levels. If it does, follow these steps:
•
Press
test tone
ON at the remote.
•
Set the volume for the speakers in the following order: Left, Center, Right, Surround.
•
Balance the pink noise tone for evenness among all individual speakers.
Instructions for this process vary, depending on the brand and model of receiver you are
using. Follow your receiver owner's guide for testing and adjusting the balance of each
speaker.
For use in video applications, be sure the SURROUND-SOUND
center mode
setting of your
receiver is on NORMAL (Figure 11).

Setting your Dolby Digital (AC-3J receiver
Your Acoustimass 10 Series II speakers are compatible with the output from Dolby Digital
(AC-3) receivers. Take special care to set the channel output according to the specifications
listed in the chart below. The cube speakers are full-range loudspeakers and must be set up
as LARGE speakers at the receiver or its TV screen menu. Turn the subwoofer OFF, but turn
the LFE (low frequency effects) ON. If available, set the crossover frequency to 200Hz.

Bass and treble adjustments
Upholstered furniture, wall-to-wall carpets, or heavy drapes can muffle treble (high notes),
making your speaker system sound bass heavy. Bare floors and walls and hard surface
furniture can make your speaker system sound too shrill. After listening to your speakers, you
may want to adjust the balance of bass and treble. You can use the bass and treble controls
on your receiver.
