Harman Kardon AVR 645 7.1 Channel Home Theater Receiver with 2 HDMI Inputs

When playing digital audio sources, the AVR 645 decodes Dolby Digital, Dolby Digital EX, DTS and DTS-ES data streams. Two-channel stereo and matrix surround sources benefit from all current Dolby Pro Logic IIx modes and DTS Neo:6. The latest version of our proprietary Logic 7 process is on-board to create a wider, more enveloping sound field and more defined surround channel positioning, regardless of the type of source material. Additional audio playback options include a direct connection to compatible computer-based sources through a direct USB connection.

Along with two HDMI inputs and three 60MHz analog component video inputs, the AVR 645 converts composite and S-video to component for single video connections. The AVR 445 also provides A/V sync delay so that lip sync errors--commonly seen when digital video processing is used in a source, program or video display--are eliminated.

Thanks to a wide range of multizone options and a standard ZR 10 remote control, the AVR 645 makes it possible to watch and listen to a separate source in one room while the main home theater uses a different source. Using the assignable rear surround channel amplifiers, you may create a basic remote listening zone without any additional equipment, or the unit's multiroom outputs may be used to feed an optional, external power amplifier and volume control. For one-wire multiroom connectivity, the AVR 645 is A-BUS/READY, requiring only a single Category 5/5e cable run and an optional remote module to power a pair of remote speakers while controlling volume and enabling full control over the program source and connected IR-controlled devices.

Product Description
The number of channels is only one factor of many when considering home-theater surround performance. Harman Kardon AVR645 focuses on sound quality with the most fidelity throughout the listening spectrum for superior realism and a pleasurable experience. AVR645 combines the sonic power of a high-current, ultrawide-bandwidth amplifier with the computer power of Texas Instruments' most advanced audio DSP to deliver unparalleled performance. With exclusive, integrated EzSet/EQ functionality, speaker, output and delay settings are automated for optimal equalization to your room acoustics. Add video conversion circuits that output all video sources via component connections with on screen graphics, a digitally-tuned AM/FM radio (that's optionally upgradeable to digital radio), and, of course, the ability to play through up to 7 speakers plus a subwoofer, this is a receiver that's worth owning.
