18SPEAKER PLACEMENTOptimally, the speakers should be placed in a circle with the listening positionat its center. The speakers should be angled so that they directly face thelistening position.front Speaker placementThe center speaker is placed either on top of, below or mounted on the wallabove or below the video display screen.The front left and right speakers are placed along the circle, about 30 degreesfrom the center speaker and angled toward the listener.Place the front left/right and center speakers at the same height, preferablyat about the same height as the listener’s ears. The center speaker should beno more than approx. 60 cm above or below the left/right speakers. If you’reusing only two speakers with the AVR 160, place them in the front left andright positions.Placement of the surround speakers depends on the number of speakers inyour system.C110°150°110°150°30° 30°SUB 1FRFLSL SRGreenPurpleWhiteBlueAlternate placement for Side SurroundLeft Speaker (Blue) Alternate placement for Side SurroundRight Speaker (Gray)GrayRedFigure 14 – Speaker Placement (5.1- Channel System)placement of Surround Speakers in a5.1- channel SystemThe side surround speakers should be placed 110 degrees from the centerspeaker, slightly behind and angled toward the listener. Alternatively, placethem behind the listener, with each surround speaker facing the opposite-side front speaker. See Figure 14. The surround speakers may be placed a littlehigher than the listener’s ears.placement of Surround Speakers in a7.1- channel SystemIn a 7.1- channel system, the side surround speakers are placed 90 degreesfrom the center speaker, directly to either side of the listening position. Thesurround back left and right speakers are placed 150 degrees from the centerspeaker, or directly facing the opposite-side front speaker.

Using the AVR 160 in a6.1-channel configuration is not recommended. The 6.1-channel formatswill sound better when played through a 7.1-channel system. The samesurround back channel information is played through both surround backspeakers, but with twice the power and clarity.To use the AVR 160 with a 6.1-channel speaker system, place the singlesurround back speaker directly behind the listener, but do not connect ituntil 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 tothe Surround Back Left Speaker Output. Then follow the directions in theAdvanced Features section for manual setup of the surround back speaker.Subwoofer placementPlacement of the subwoofers is less critical, since low-frequency sounds areomnidirectional. Placing each subwoofer close to a wall or in a corner willreinforce the low frequencies, and may create a “boomy” sound. Temporarilyplace one subwoofer where the listener normally sits, then walk around theroom until the low frequencies sound best. Place the subwoofer in that spot.NOTE: Your receiver will sound its best when the same model or brandloudspeaker is used for all positions.
