SPEAKER PLACEMENT
Optimally, the speakers should be placed in a circle with the listening position at its center. The speakers should be angled so that they directly face the listening position. The surround back left and right speakers are placed 150 degrees from the center speaker, or directly facing the opposite-side front speaker. See Figure 16.

SUB C FL

Front Speaker Placement
The center speaker is placed either on top of, below or mounted on the wall above or below the video display screen. The front left and right speakers are placed along the circle, about 30 degrees from the center speaker and angled toward the listener. Place the front left/right and center speakers at the same height, preferably at about the same height as the listeners ears. The center speaker should be no more than two feet above or below the left/right speakers. If youre using only two speakers with the AVR 3550HD, place them in the front left and right positions. Placement of the surround speakers depends on the number of speakers in your system.

Figure 16 Speaker Placement (7.1-Channel System)
NOTE: Some speaker manufacturers offer 6.1-channel speaker systems, for 6.1-channel surround sound formats, such as Dolby Digital EX, DTS-ES Discrete and Matrix modes and DTS Neo:6 mode. We do not recommend using the AVR 3550HD in a 6.1-channel configuration. The 6.1-channel formats will sound better when played through a 7.1-channel system. The same surround back channel information is played through both surround back speakers, but with twice the power and clarity. To use the AVR 3550HD with a 6.1-channel speaker system, place the single surround back speaker directly behind the listener, but do not connect it until after you have run the EzSet/EQ procedure for a 5.1-channel system. After the EzSet/EQ process finishes, connect the surround back speaker to the Surround Back Left Speaker Output. Then follow the directions in the Advanced Features section for manual setup of the surround back speaker.

Surround Mode DTS-HD Description DTS-HD is a new high-definition audio format that complements the high-definition video found on Blu-ray Disc and HD-DVD discs. It is transmitted using a DTS core with high-resolution extensions. Even when only DTS 5.1 surround sound is desired (or available, if the multizone system is in use), the higher capacity of high-resolution discs serves up DTS at twice the bit rate used on DVD-Video discs. DTS-HD Master Audio technology delivers bit-for-bit reproductions of the studio master recording in up to 7.1 channels, for an incredibly accurate performance. DTS Extended Surround adds a single surround back channel to DTS 5.1 digital surround sound. The Matrix version includes the surround back channel information matrixed into the left and right (side) surround channels, for compatibility with 5.1-channel systems. DTS-ES Discrete is another Extended Surround mode that adds a surround back channel, but this information is encoded discretely on the disc, and is not derived from information contained in the surround channels. Delivers a 2-channel downmix of DTS Digital materials, or presents a matrix-encoded surround presentation.

5-Channel Stereo

Useful for parties, the left- and right-channel information is played through both the front and surround speakers on each side, while the center speaker plays a summed mono mix. Expands the 5-Channel Stereo presentation to include the surround back channels. Turns off all surround processing and plays a pure 2-channel signal. The signal is digitized and bass management settings are applied, making it appropriate when a subwoofer is used. Maintains an analog input signal in that form, bypassing all digital processing (i.e., surround and bass management). Requires Tone Control setting to be off.
