Harman-Kardon PA5800 owner manual Installation and Connections, Power Control Connections

Note: When making any connections between source components, proces- sors or preamplifiers and the PA5800, or when making any connections to speakers, be certain that both the input device and the PA5800 are turned off. To ensure that there will be no unwanted signal transients that can damage equipment or speakers, it is always best to unplug all equipment from AC power outlets before making any connections. Modern electronic products often have a “standby” mode that may be activated even though the product may appear to be turned off.

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.

NOTE: Before making any connections to remote trigger outlets, it is critical that both the PA5800 and the triggering device be turned off. For additional safety, it is best that these connections be made while both products are unplugged from AC power sources.

Remote Turn-On with Compatible Harman Kardon Products – including the PT2500

Connect one end of the accessory cable supplied with the PT2500 to the Remote Amp Trigger in ¢ jack on the rear of the PA5800. Connect the other end to the jack on the PT2500 that carries the same identification.

Remote Turn-On Using an External AC- to-DC Converter

If the PA5800 is not used with a compati- ble Harman Kardon product, it is still possible to activate the unit for auto- matic turn-on.

To control the amplifier in this manner you will need a small AC-to-DC power converter capable of delivering a 6- to

12-volt DC signal. The DC voltage should terminate in a standard 3.5mm mono miniplug. This type of converter may be obtained as a “Power Adapter” from many electronics retailers. Consult your dealer for further information.

Plug the AC adapter into a switched out- let 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.

Audio System Connections

As a general rule, avoid running any input signal or speaker wire connections next to or parallel with AC power cords. This may cause undesired hum or other interference that will greatly degrade sig- nal performance.

When making connections with RCA- type plugs on interconnect cables, make certain to gently but firmly insert the plugs into the jacks on the rear of the PA5800. Loose connections can cause intermittent sound and my damage your speakers.

Connect the outputs of the PT2500 or your surround processor to the audio inputs of the PA5800 ª. To simplify installation, it is best to follow the mark- ings on the rear panel by connecting the Front Right output of the PT2500 to the Front Right input on the PA5800, follow- ing the same pattern for each channel.

Important Note: The PA5800 is not designed for use in Bridged configu- ration. 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 perfor- mance that will occur.
