21SPEAKER PLACEMENTBefore you begin to connect cables, it is important to place your speakersin their correct locations in the room.Optimally, the speakers should be placed in a circle with the listeningposition at its center. The distance from the listening position to thevideo display forms the radius of the circle.The speakers should be angled so that they directly face the listeningposition.Front Speaker PlacementThe center speaker is placed either on top of, below or mounted on thewall above or below the video display screen.The front left and right speakers are placed along the circle, about 30degrees from the center speaker and angled toward the listener.It is best to place the front left/right and center speakers as close tothe same height as possible, preferably at about the same height asthe listener’s ears. In any event, the center speaker should be no morethan two feet above or below the left/right speakers.Placement of the surround speakers depends on the number ofspeakers in your system. If you’re using only two speakers with theAVR 247, place them in the front left and right positions, and skip tothe Installation section. However, Harman Kardon recommends usingthe AVR 247 in a 5.1- or 7.1-channel configuration for optimalsurround sound performance.Figure 15 – Speaker Placement (5.1-Channel System)Placement of Surround Speakers in a 5.1-ChannelSystemThe side surround speakers should be placed 110 degrees from thecenter speaker, that is, slightly behind and angled toward the listener.If this isn’t feasible, place them behind the listener, with each surroundspeaker facing the opposite-side front speaker. See Figure 15. Thesurround speakers may be placed a little higher than the listener’s ears.Placement of Surround Speakers in a 7.1-ChannelSystemIn a 7.1-channel system, the side surround speakers are placed 90 degreesfrom the center speaker, directly to either side of the listening position,which is different than in a 5.1-channel system. The surround back leftand right speakers are placed 150 degrees from the center speaker, ordirectly facing the opposite-side front speaker. See Figure 16.Figure 16 – Speaker Placement (7.1-Channel System)NOTE: Some speaker manufacturers offer 6.1-channel speakersystems, which are compatible with the 6.1-channel digitalsurround sound formats available on DVD and elsewhere, suchas Dolby Digital EX and DTS-ES Discrete and Matrix modes.We do not recommend using the AVR 247 in a 6.1-channelconfiguration. In fact, the 6.1-channel formats will sound betterwhen played through a 7.1-channel system. The same surroundback channel information is played through both surround backspeakers, but with twice the power and clarity.If you wish to use the AVR 247 with a 6.1-channel speakersystem, place the single surround back speaker directly behindthe listener, but do not connect it until after you have run theEzSet/EQ procedure for a 5.1-channel system. After EzSet/EQfinishes, connect the surround back speaker to the Surround BackC90°150° 90°150°30° 30°SUBFRFLSLSBL SBRSRCAlternate placementfor Side SurroundLeft SpeakerAlternate placementfor Side SurroundRight Speaker110°150°110°150°30° 30°SUBFRFLSL SR
