13、standard CDs. The Harman Kardon AVR 8500 features two additional breakthrough audio technologies, Logic 7 and VMAx. Available exclusively in A/V receivers from Harman Kardon, Logic 7 is a sophisticated DSP system that provides multichannel reproduction from matrix-encoded and two-channel stereo reco

14、rdings that is superior to what was previously attainable; it is available in the AVR 8500 in four configurations. Both the Logic 7 Cinema and Movie modes are available for either seven-main- channel (Logic 7/7.1) or five-main-channel (Logic 7/5.1) output, depending on the speaker configuration in u

15、se. Logic 7s Music mode reproduces two-channel recordings through a multichannel speaker system with increased imaging accuracy, separation and directionality, along with a greater sense of envelopment. The Logic 7 Cinema Mode improves playback of any matrix surround-encoded material, for a wider fr

16、ont soundstage and smoother and more accurate pans between front and rear. The AVR 8500 also incorporates patented VMAx Near and Far Mode Virtual Theater audio processing, a digital signal-processing method of producing realistic, high-fidelity, three-dimensional surround-sound audio in 360 degrees

17、using just two loudspeakers. Thanks to its proprietary, extremely sophisticated processing algorithms and vast processing power, VMAx enables listeners to enjoy a truly enveloping sonic presentation even when only two loudspeakers are in use. VMAx accepts either discrete or matrix-encoded multichann

18、el output and processes them into two channels in such a way that listeners believe they are listening to sounds from five speakers left, center and right front and left and right surround. Conventional two-channel-stereo program material is also improved to provide a much wider and deeper soundstag

19、e; one that extends well beyond the locations of the loudspeakers. The listener can choose from Near and Far modes, for an up-close or more distant listening perspective.
