Harman Kardon AVP-2 Owners Manual - Page 4

BECOMING ACQUAINTED WITH YOUR AVP2 The AVP2 is the most advanced preamp/AV control center/surround processor available in it's price range. In addition to extensive audio processing capabilities, the AVP2 incorporates a comprehensive audio-video switcher. The entire unit is microprocessor controlled utilizing an LED display system to provide visual indications of the operational status. AVP2 INNOVATIONS AND TECHNOLOGY The AVP2 incorporates a combination of existing and new technology: Proprietary high speed Digital Servo Logiclm system and other advanced surround technology designed by Jim Fosgate for use with both surround encoded and non-encoded stereo audio sources ▪ Dolby Pro Logic Surround for encoded motion pictures, stereo CDs and television audio soundtracks. ▪ Proprietary Music Surround modes (Rock and Popular) which deliver true stereo surround. The AVP2 incorporates a comprehensive menu of pre-programmed modes for playback of music sources. Some modes may be altered to suit listening tastes or environmental requirements. FEATURES In addition to a wide range of listener-selectable surround parameters, the AVP2 provides a number of beneficial operating features. These include: automatic input balance calibration, a built-in test noise sequencer, adjustable output level trim controls, A/V input switching, a separate A/V record output circuit, direct remote access of inputs and surround parameters, automatic memory update of important changes to specific surround parameters. A complete description of operating features begins on this page. MOTION PICTURE SURROUND PARAMETERS Two parameters for the playback of motion picture soundtracks are provided. They are Dolby Pro Logic and our proprietary 70mm mode. A complete description of all AVP2 surround parameters is found on page 6. OPERATING FEATURES The AVP2 incorporates a number of operational features which have been designed to enhance the performance and versatility of your home surround audio system. An explanation of each feature and application follows each listing. Selectable Bass Equalization Three levels of bass boost (4, 8, and 12 dB) are selectable from the handheld remote control. As the boost is increased, the range of maximum boost is shifted upward from about 30 Hz to 60 Hz. Normally, with most systems no more than 4 or 8 dB of boost will be required once proper output level and woofer placement is determined. High Frequency Equalization This circuit is useful with program material which sounds "hot" or bright. It can be manually switched in with the handheld remote control. An indicator light on the front panel indicates when the high frequency re-equalization circuit is switched on. Steering Logic Display This display provides a visual indication of steering logic activity. As an example, a center front signal, such as dialogue, will illuminate the center top LED while surround encoded signals will illuminate the bottom LEDs. During use with a stereo signal, the entire array will constantly change illumination levels on a dynamic basis. A monophonic signal will only illuminate the center top LED. Because of the wide dynamic range of Digital Servo Logic, when no audio signal is present, the LED indicators may differ in illumination as a result of normal production variations and the varying noise floors of audio sources in the system. Source Select This function, available via the remote and the front panel of the AVP2, selects the desired A/V input. A desired source may be directly selected from the handheld remote control. Record Select This function, available only from the front panel of the AVP2, selects the A/V source for recording purposes or to be distributed to a second room location. The record output stereo audio is unprocessed. Composite video is not transcoded to S-type video or vice-versa. 3
