The PA5800 has been carefully designed to deliver the best possible sonic performance, along with outstanding industrial design that matches other Harman Kardon products or complements any interior design. In order to fully enjoy the performance of your amplifier, please take a few minutes to read this owner's manual. [. . . ] Do not connect the same input or speaker to more than one channel. To ensure that the high-quality signals produced by the PA5800 are carried to your speakers without loss of clarity or resolution , we recommend that you use high-quality speaker cable. Many brands of cable are available, and the choice of cable may be influenced by the distance between your speakers and the amplifier, the type of speakers you use, personal preferences and other factors. Your dealer or installer is a valuable resource to consult in selecting a proper cable for connections between your amplifier and speakers. Regardless of the brand or type of cable selected, we recommend that you use a cable constructed of fine, multistrand copper with a gauge of 14 or smaller. When specifying cable, remember that the lower the number, the thicker the cable. Cable with a gauge of 16 may be used for short runs of less than ten feet. We do not recommend the use of cables with an AWG equivalent of 18 or higher due to the power loss and degradation in performance that will occur. Power Control Connections The Harman Kardon PA5800 amplifier features a built-in remote turn-on system that will automatically turn on the amplifier when another device in the system is switched on. To activate this system, this amplifier must be used in conjunction with a Harman Kardon PT2500, other compatible Harman Kardon products or other approved devices. The negative wire should be connected to the black terminal on the PA5800 and the speakers. If bare wire is used for connections, strip approximately 3/4" (20mm) of insulation from the end of each wire and carefully twist the strands of each conductor together. Be careful not to cut the individual strands or twist them off; for optimal performance, all strands must be used. Next, loosen the knobs of the speaker output terminals far enough so that the cap moves back on its threads past the U-shaped groove at the back end of the terminal. Making certain that you observe polarity by connecting the negative (-) wire to the black terminal and the positive (+) wire to the red terminal, pass the exposed wire through from the top of the slot until the wire is visible from the bottom end. Holding the wire in place, twist the cap back so that the connection is secured. Do not overtighten or use tools, as this may damage the plastic terminal cap or break the delicate wire strands and decrease system performance. Important Note: When making speaker wire connections, be certain that none of the strands from one lead touch any other lead. This will cause a short circuit and may damage you amplifier or speakers. Damage from short circuits caused in this manner is not covered by the product warranty. Connections may also be made using standard 4mm OD banana plugs. Before using a banana-type jack, make certain that the plastic screw caps on the PA5800 are firmly tightened by turning them clockwise until they are snug against the chassis. This will ensure that the maximum surface area of the plug is in contact with the jack. [. . . ] This is your indication that the PA5800 is in standby mode. Manual Operation If the unit is not being used with the automatic, remote turn-on system and the AC power plug is connected to a live outlet, the ring surrounding the power switch will glow red. This is your indication that the unit is functional. Service Information / Troubleshooting 7 If your installation has followed the procedures in this manual, you should enjoy many years of trouble-free operation and high-quality listening enjoyment. The PA5800 does not contain any user-serviceable parts. If you suspect a problem that may require service assistance, contact your dealer, installer or an authorized Harman Kardon service depot.
