User manual HARMAN KARDON PA2400

[. . . ] It is always a good idea to avoid using any audio equipment on the same AC circuit as equipment with motors, such as air conditioners or refrigerators. This will lessen the possibility of power variation and electrical start-up noise affecting your sound system. Do Not Use Extension Cords To avoid safety hazards, use only the power cord supplied with your unit. If a replacement cord is used, make certain that it is of a similar gauge. [. . . ] Do not place CDs, record jackets, owner's manuals or other paper on top of, or beneath the unit, or in between multiple amplifiers in a stack. This will block the air flow, causing degraded performance and a possible fire hazard. If the unit is to be enclosed in a cabinet or rack, make certain that there is adequate air circulation, with means provided for hot air to exit and for cool air to be brought in.

Installation and Connections 4 Note: When making any connections between source components, processors or preamplifiers and the PA2400, or when making any connections to speakers, be certain that both the input device and the PA2400 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. Remote Turn-On Using an External ACto-DC Converter If the PA2400 is not used with a compatible Harman Kardon product, it is still possible to activate the unit for automatic turn-on. Questions about running cables inside walls should be referred to your installer or a licensed electrical contractor who is familiar with the NEC and/or the applicable building or electrical codes in your area. Connections to Speakers The final step of the installation process is to connect the amplifier to your speakers using high-quality cable. Note that one conductor of the speaker cable will have no markings or an indication of "-" for negative polarity, and the other will have a red line, brandname markings, a colored thread or some other positive-polarity indication. For example, make certain that the cable length connecting left and right front or left and right rear (surround) speakers is identical, even though one speaker may be physically closer to the amplifier than the other. Do not coil any excess cable, as this may become an inductor that creates frequency response variations in your system. Connect the wires to the speakers, again being certain to observe proper polarity. Remember to connect the negative or black wire to the matching terminal on the speaker. Similarly, the positive or red wire should be connected to the like terminal on the speaker. NOTE: While most speaker manufacturers adhere to an industry standard of using black terminals for negative and red ones for positive, some manufacturers may not adhere to this configuration. To ensure properly phased connections and optimal performance, consult the identification plate on your speaker terminals, or the speaker's manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer or installer for advice before proceeding, or consult the speaker's manufacturer. Operation 6 Operation of the PA2400 is simple.
