System ConfigurationWhen all audio, video and system con-nections have been made, there are a fewconfiguration adjustments to be made. Afew minutes spent to correctly configureand calibrate the unit will greatly add toyour listening experience.Speaker SelectionThe placement of speakers in a multi-channel home theater system can havea noticeable impact on the quality ofsound reproduced.No matter which type or brand of speakersis used, the same model or brand ofspeaker should be used for the front left,center and right speakers. This creates aseamless front soundstage, and elimi-nates the possibility of distracting sonicdisturbances that occur when a soundmoves across mismatched front channelspeakers.Speaker PlacementDepending on the type of center channelspeaker in use and your viewing device,place the center speaker directly above orbelow your TV or in the center behind aperforated front projection screen.Once the center channel speaker isinstalled, position the left and right frontspeakers so that they are as far awayfrom one another as the center channelspeaker is from the preferred listeningposition. Ideally, the front channelspeakers should be placed so that theirtweeters are no more than 24″ off centerfrom the tweeter in the center channelspeaker.Depending on the specifics of your roomacoustics and the type of speakers in use,you may find that imaging is improvedby moving the front left and right speakersslightly forward of the center channelspeaker. If possible, adjust all frontloudspeakers so that they are aimed atear height when you are seated in thelistening position.Using these guidelines, you’ll find that ittakes some experimentation to find thecorrect location for the front speakers inyour particular installation. Don’t beafraid to move things around until thesystem sounds correct. Optimize yourspeakers so that pans across the front ofthe room sound smooth, and that soundsfrom all speakers appear to arrive at thelistening position at the same time with-out delay from the center speaker asopposed to the left and right speakers.Surround speakers should be placed onthe side walls of the room, at or slightlybehind the listening position. The centerof the speaker should face into the room.The speakers should be located so thatthe bottom of the cabinet is at least twofeet higher than the listeners’ ears whenin the desired area.If side wall mounting is not practical, thespeakers may be placed on a rear wall,behind the listening position. Again, theyshould be located so that the bottom ofthe cabinet is at least two feet higherthan the listeners’ ears. The speakersshould be no more than six feet behindthe rear of the seating area.Subwoofers produce non-directionalsound, so they may be placed almostanywhere in a room. Subwoofer place-ment is highly influenced by room sizeand shape, and the type of subwooferused. Follow the instructions of the sub-woofer’s manufacturer, or experimentwith the best location for a subwoofer inyour listening room.17Right FrontSpeakerLeft FrontSpeakerNo morethan 24″Center Front SpeakerA) Front Channel Speaker Installationwith Direct View TV Sets or Rear ScreenProjectorsCenter FrontSpeakerOptional Rear Wall MountingTV or Projection ScreenRight FrontSpeakerLeft FrontSpeakerNo more than 6 feetwhen rear-mountedspeakers are usedAt least 2 feetAt least 6 inches from ceilingB) The distance between the left and rightspeakers should be equal to the distancefrom the seating position to the viewingscreen.
