4、WER SWITCH/INDICATOR PCB.18 Rev B9 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 conne

5、cting 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

6、 use tools, as this may damage the plastic terminal cap or break the delicate wire strands and decrease system performace. Important Note: When making speaker wire connections, be cartain that none of the strands from one lead touch any other lead. This will cause a short circuit and may damage your

7、 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 0D banana plugs. Before using a banana-type jack, make certain that the plastic screw caps on the PA5800/2.1 are firmly tightened by turnin

8、g 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. Once the wire has been attached to the banana plug following the plug manufactures instructions, simply insert the banana plug into the hole provided on t

9、he rear of the colored screw caps on the terminal posts. Be certain to observe proper polarity. Finally, run the cables to the speaker locations. It is highly recommended that the length of cable connecting any pair of speakers be identical. For example, make certain that the cable length connecting

10、 left and right front or left and right rear (surround) speaker is identical, even though one 5 Multichannel Power AmplifierHarman KardonPA5800 / SIGNATURE 2.1 6 8 6 Multichannel Power AmplifierHarman KardonPA5800 / SIGNATURE 2.1 speaker may be physically closer to the amplifier than the other. Do n

11、ot coil any excess cable, as this may become an inductor that creates frequency response variations in your system. Connect the wire to the speaker, again being certain to observe proper polarity. Remember to connect the negative or black wire to the matching terminal on the speaker. Similarly, the

12、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 for positive, some manufacturers may not adhere to this configuration. To ensure properly phased connectio

13、ns and optimal performance, consult the identification plate on your speaker terminals, of the speakers 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 speakers manufacturer. OPERATION The PA5800/2.

14、1 may be operated in either a manual or automatic mode. If the unit is being used in a stand-alone operation you should follow the instructions below for Manual Operation. When the PA5800/2.1 is connected to another compatible device such as the Signature 2.0 or PT2500 tuner, follow the instructions

15、 for Automatic Operation. Make sure the power switch is in the off position before plugging in the AC power cord. After all the connections have been made to the amplifiers input jacks and speaker terminals, connect the power cord to an AC outlet. Turn on your source component and receiver/processor

16、 first; start with a low volume level to protect your speakers. Manual Operation The LED indicator should be glowing red if the unit is plugged in. Press the front panel switch to turn the unit on. PA5800 - The indicator surrounding the power switch will turn green after a brief pause. Signature 2.1

17、 - The indicator will flash green briefly, and then go out; the front panel will then illuminate to blue. To turn the unit off, press the power switch again. The LED indicator will return to red. Automatic Operation Before proceeding, make certain the connection between the Signature 2.0, PT2500, or

18、 other trigger source has been connected properly to the unit following the previous directions. At this point the trigger source should be off. After all cables are connected and the PA5800/2.1 is plugged in, the LED Indicator should be glowing red. Press the power switch and the indicator will tur

19、n amber indicating the unit is in the standby mode and ready to turn on when it receives a signal from the triggering device. Finally, turn on your Signature 2.0, PT2500, or other trigger source to turn the PA5800/2.1 on. PA5800 - The indicator surrounding the power switch will turn green after a br

20、ief pause. Signature 2.1 - The indicator will flash green briefly, and then go out; the front panel will then illuminate to blue. At the conclusion of your listening session, there is no need to turn the PA5800/2.1 off manually. When the Signature 2.0, PT2500, or other trigger source is turned off,

21、the PA5800/2.1 will return to the standby mode. Important Note: If you will not be using your audio system for an extended period of time, such as a vacation, we recommend turning the PA5800/2.1 off using the power switch. IDLE CURRENT ADJUSTMENT PA5800/Signature 2.1 Locate test points: PA5800 - P75

22、A, P75B, P75C, P75D, P75E Signature 2.1 - P2, P4, P6, P8, P10 These are 2 pin female molex connectors (5 total, 1 per channel) on the MAIN AMPLIFIER PCB. Attach a DC voltmeter (set to a low range) to these points. This is best accomplished by making up a “test plug” using a male molex connector that

23、 fits into the one in the unit, with wires attached, for connection to the voltmeter.An alternative method is to use two “mini-grabbers” to attach to the two outer pins on each connection.Warning: Do not accidentally short the two points together with a meter probe during adjustment. Adjustment Poin

24、ts: PA5800 - R70A, R70B, R70C, R70D, R70E Signature 2.1 - R22, R55, R103, R151, R199 Adjust to 25mv across test points, one channel at a time until all channels comply. 7 Multichannel Power AmplifierHarman KardonPA5800 / SIGNATURE 2.1 TROUBLE SHOOTING The items listed below are a brief guide to mino
