Be sure to connect thespeakers correctly.Speaker impedanceAfter confirming the speaker impedance indications printed on therear panel of the receiver, connect speakers with matching imped-ance ratings. Using speakers with a rated impedance other than thatindicated on the rear panel of the receiver could result in malfunctionsor damage to the speakers or receiver.Speaker placementFront speakers : Place at the front left and right of the listeningposition. Front speakers are required for all surround modes.Center speaker : Place front and center. This speaker stabilizes thesound image and helps recreate sound motion. Required for surroundplayback.Surround speakers : Place at the direct left and right, or slightlybehind, the listening position at even heights, approximately 1 meterabove the ears of the listeners. These speakers recreate soundmotion and atmosphere. Required for surround playback.Subwoofer : Reproduces powerful deep bass sounds.Surround back speaker : Place the speaker directly at the rear of thelistening position. The optimum position depends mainly on the roomcondition.• Although the ideal surround system consists of all the speakerslisted above, if you don't have a center speaker or a subwoofer, youcan divide those signals between the available speakers in thespeaker settings steps to obtain the best possible surround repro-duction from the speakers you have available. *Channel space switching(Except for the U.S.A., Canada, U.K., and Australia)The space between radio channels has been set to the one thatprevails in the area to which the system is shipped. However, if thecurrent channel space setting does not match the setting in the areawhere the system is to be used, for instance when you move fromarea 1 or area 2 shown in the following table or vice versa, properreception of AM/FM broadcasts cannot be expected. In this case,change the channel space setting in accordance with your area byreferring to the following table.Area CHANNELSpace Frequency1 U.S.A., Canada and South FM: 100 kHzAmerican countries AM: 10 kHz2 Other countries FM: 50 kHzAM: 9 kHz50usAM 9kHzFM50kHz75usAM 10kHzFM100kHzDE-EMPHASISCHANNEL SPACEDE-EMPHASISCHANNEL SPACE50usAM 9kHzFM50kHz75usAM 10kHzFM100kHzTurn the power OFF by pressing the POWER key before moving theswitch level.
