Harman Kardon PA 2000 Owners Manual - Page 3

Introduction Congratulations! As the owner of a PA 2000 Multichannel/Multizone Power Amplifier, you have at your command a unique product. The PA 2000 has been carefully designed to deliver the best possible sonic performance, along with unique features that make it as much at home in a multiroom audio system as it is in providing power to the additional surround channels required for the latest digital audio formats. The PA 2000 is alone among audio power amplifiers in being designed to accommodate the long speaker runs required for multiroom applications without sacrificing the ultrawidebandwidth circuitry and high-current capability technologies that are key to Harman Kardon's long-standing tradition of audio amplifier excellence. As an added audiophile touch, five-way speaker terminals ensure a secure connection to large-gauge speaker wire, and individual output level trim controls enable output balance to be set precisely. Along with power and performance, the PA 2000 provides the flexibility for a variety of applications. In the four-channel/two-pair output mode, the input is routed to two pairs of speakers for use with AV receivers equipped with multiroom capability. In the two-channel bridged mode, a high-output stereo pair is available for use as the rear surround channels in a 7.1 channel system or for use with a stereo preamplifier. For installations requiring multiple amplifiers, a pair of parallel outputs allows the same signal to be fed to multiple PA 2000s. To allow the widest range of system options, the PA 2000 includes both Music Sense circuitry, which automatically turns the amplifier on when an audio signal is present, and a lowvoltage trigger for compatibility with multiroom controllers. In order to fully enjoy the performance of your amplifier, please take a few minutes to read this owner's manual. It contains important information that will help you to make certain that the amplifier is properly configured for operation with the rest of the equipment in your system. If you have any questions about this product, its installation or its operation, please contact your retailer or custom installer. They are your best source of product information. Welcome to the Harman Kardon family. We wish you many years of listening pleasure!
