SYSTEM CONFIGURATION 6.1-Channel System Video Screen Center Speaker starting on page 26 for manual setup to manually configure your surround back speaker. Front Left Speaker 30° Front Right Speaker 30° 110° 110° We recommend that you consider adding a second surround back speaker as soon as possible. Surround Speakers for 7.1 Systems For the ultimate home theater experience, a 7.1 surround system uses both traditional surround left/right channels and a surround back left/right speaker pair. In a 7.1 system, the front left/center/right speakers remain in the same place as they would be for a 5.1 or 6.1 system, but due to the number of speakers involved, the placement of the surround speakers is different. Side Surround Left Speaker Listening Position Side Surround Right Speaker In a 7.1 system, you should place the main surround left/right speakers at the 90-degree point on our circle. A good way to visualize proper surround speaker positioning for 7.1 is to place the speakers directly to the left and right of the ears of someone sitting in the prime listening spot. The two speakers should ideally face toward each other. Back Surround Speaker The additional set of Surround Back Left/Right speakers is placed at about 150 degrees on the circle, pointing inward toward the listening area. The easiest way to visualize the placement of these speakers is to place the surround back left speaker directly opposite the right front speaker and to place the surround back left speaker directly opposite the left front speaker. Surround Speakers for 6.1 Systems A 6.1 surround speaker adds an additional center back surround speaker to the system, enabling you to enjoy the benefits of advanced surround modes such as Dolby Digital EX, DTS-ES and Harman Kardon's proprietary Logic 7/7.1 processing. To step up to a 6.1 system, first place the speakers for a 5.1 system, as shown on page 18. The "sixth" speaker should ideally be placed at the center of the room's rear wall, pointing directly toward the front center channel speaker. NOTE: The 6.1-channel configuration is not recommended for the AVR 240. We strongly recommend a 7.1-channel installation as described below. When 6.1-channel materials are played through a 7.1-channel system, the same surround back channel information is played through both the left and right surround back speakers.

In that case, we suggest you install all of your speakers except the surround back speaker, and run the EzSet+ procedure for a 5.1-channel system (see page 24). After EzSet+ has finished, connect the single surround back speaker to the left Surround Back Speaker Outputs 9.
