Bose Acoustimass 10 Series II Owner's guide - Page 15

English 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 surroundsound 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).

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. AM194646_02_V.pdf October 22, 2001 13
