User manual HARMAN KARDON PA5800

[. . . ] If you have any questions about the voltage requirements for your specific model, or about the line voltage in your area, contact your selling dealer before plugging the unit into a wall outlet. Verify AC Circuit Capacity Before Use High power output of your amplifier may require heavy current draw under full load conditions. To ensure proper performance and avoid potential safety hazards, we recommend that it be connected to a circuit with 20-amp capacity. Connecting multiple amplifiers to the same circuit, or connecting the amplifier to a circuit used by other heavy-power devices, such as high-wattage lights, may cause circuit breakers to trip. [. . . ] Plug the AC adapter into a switched outlet that will be activated when you wish to have the amplifier turn on. This may be the switched outlet at the rear of an AV receiver or other audio equipment, an AC outlet that is part of a current sensing control unit activated by a preamp or surround processor or a switched AC wall outlet. Connect the 3. 5mm miniplug from the power converter to the Remote Amp Trigger in ¢ jack on the rear of the PA5800. Connect the outputs of the PT2500 or your surround processor to the audio inputs of the PA5800 TM. To simplify installation, it is best to follow the markings on the rear panel by connecting the Front Right output of the PT2500 to the Front Right input on the PA5800, following the same pattern for each channel. Important Note: The PA5800 is not designed for use in Bridged configuration. 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. [. . . ] Input/Output Protection Under some conditions, such as a shorted speaker wire, DC voltage on an input connection or thermal overload, the Harman Kardon PA5800 will place itself in a "protect" mode to prevent damage to the amplifier. When this happens, the ring surrounding the power switch will flash and alternate between red and amber. When this occurs, IMMEDIATELY turn off the unit using the power switch and correct the problem. If the unit continues to go into a protect mode, contact your dealer or installer for assistance.
