A Dolby Pro-Logic receiver set for NORMAL surround-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-3) 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.

Speaker	Setting at receiver
Left and Right Front	Large
Center	Large
Left and Right Surround	Large
LFE (low frequency effects)	ON
Subwoofer	OFF
Crossover frequency	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.
