The Harman Kardon AVR 645 home theater receiver serves as the hub of your home entertainment system, providing a wide range of listening possibilities for almost any audio or video program source. This 7.1-channel surround sound receiver pumps out 75 watts of power per channel (with all channels operating at full power), for 525 watts of total power. The AVR 645's seven-channel amplifier provides the power to reproduce the loudest crescendos or cinema sound effects while remaining virtually free from distortion or system noise. It includes two HDMI inputs for uncompressed digital audio and video via a single cable. And it's compatible with the optional Harman Kardon Bridge, which links the receiver to your Apple iPod and enables you to control playback of individual songs and playlists via the Harman Kardon remote control.

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.

Other features include:

• All popular digital and matrix surround modes, including Dolby Digital, Dolby Digital EX, Dolby Pro Logic II, DTS, DTS-ES Discrete and Matrix, DTS Neo:6 and DTS 96/24
• EzSet/EQ for quick and accurate system setup and room correction
• Dolby Virtual Speaker processing for use when less than a full 5.1 or 7.1 speaker complement is available
• Dolby Headphone for spacious, open sound when using headphones
• USB connectivity for audio playback with compatible computers and quick system upgrades
• Full bass management for all inputs, including the analog direct inputs for high-resolution DVDs, DVD-Audio and SACD players, including Quad Crossover settings and individual settings for each input
• Front-panel analog audio/video jacks may be used as either inputs or outputs for connection to the latest portable products or video game consoles
• Backlit, eight-device, programmable learning remote control with two-line LCD display

It includes the following audio/video connections:

• Coaxial digital: 4 in (1 front, which is switchable to output), 1 out
• Optical digital: 4 in (1 front), 1 out
• Composite audio/video/S-Video: 5 in (1 front, which is switchable to output), 2 out

What's in the Box
Receiver, remote control (with batteries), EzSet/EQ microphone, extender rod for microphone, AM antenna, FM antenna, AC power cord, printed operating instructions Versatility at its best! The AVR 645 not only switches two HDMI 1.1 sources, it is able to decode Dolby Digital, DTS and PCM audio streams from the HDMI inputs. Add USB audio, iPod connectivity and XM-Ready capability to our EzSet/EQ system and high-current amplifier, and the AVR 645 performs with ease. Equally impressive on the video side is format conversion so that all analog video inputs may be viewed via component outputs, and A/V Sync Delay, which reconnects the timing of sound and images. There is no better combination of sound and image anywhere.
