Harman Kardon AVR 645 Owners Manual - Page 3

INTRODUCTION Thank you for choosing Harman Kardon! With the purchase of a Harman Kardon® AVR 645, you are about to begin many years of listening enjoyment. The AVR 645 has the most extensive range of audio and video processing, control and connectivity options ever offered by Harman Kardon, enabling it to provide the best possible audio and video reproduction with any type of source material. Teaming advanced processing circuitry with proprietary technologies such as EzSet/EQ, the AVR 645 seamlessly integrates every component in your entertainment system to deliver the best possible sound and images. Some of the leading-edge features that are available with the AVR 645, such as HDMI™ connectivity and XM-Ready® operation, are new to even the most experienced home theater enthusiast. Although the power of the AVR 645 makes them easy to use, we strongly recommend that you take a few minutes to read this owner's manual to familiarize yourself with how the full suite of AVR 645 features and capabilities are configured and used in day-to-day operation. This small investment of time will yield significant dividends in taking the maximum advantage of this new addition to your home theater system. If you have any questions about this product, its installation or its operation, you may also access a wealth of information and assistance by visiting our Web site at www.harmankardon.com. Description and Features The AVR 645 serves as the hub of your home entertainment system, providing a wide range of listening possibilities for almost any audio or video program source, whether it is the broadcast of a movie or sporting event in HDTV or a vintage mono or stereo recording. When playing digital audio sources from either the conventional optical and coaxial inputs, or through the HDMI 1.1-compliant connections, 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 and processing options include a direct connection to compatible computer-based sources through a direct USB connection. The AVR 645 takes the "video" part of its name seriously. Along with two HDMI inputs and three 100MHz analog component video inputs, the AVR 645 converts incoming analog signals to an HDMI output or converts composite and S-video to component for single wire connections. Tying audio and video together, the AVR 645 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. Along with the latest advances in digital audio and video technology, Harman Kardon recognizes that some things remain constant, and in the case of the AVR 645 that is a requirement for audio power best served by our time-honored high-current, ultrawidebandwidth amplifier design. The AVR 645's sevenchannel amplifier provides the power to reproduce the loudest crescendos or cinema sound effects while remaining virtually free from distortion or system noise. With a combination of state-of-the-art circuitry, digital technology and proven performance with an elegant design that is compatible with the latest source components and video displays, the AVR 645 represents the culmination of Harman Kardon's fifty-plus-year history of delivering the finest sonic performance.
