Connections to Speakers

PA5800 / SIGNATURE 2.1

Connect the 3.5mm miniplug from the power converter to the Remote Amp Trigger in 8 jack on the rear of the PA5800/2.1.

The final step of the installation process is to connect the amplifier to your speaker using high-quality cable. A pair of binding posts is provided for each channels output. These posts will accept bare wire or banana-type plugs. 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 read line, brand-names markings, a colored thread or some other positive-polarity indication.

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 signal 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 PA5800/2.1. Loose connections can cause intermittent sound and may damage your speakers. Connect the outputs of the PT2500 or your surround processor to the audio inputs of the PA5800/2.1 6 . 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 PA5800/2.1, following the same pattern for each channel. Important Note: The PA5800/2.1 is not designed for use in Bridged configuration. Do not connect the same input or speaker to more than one channel. To ensure that the high-quality signals produced by the PA5800/2.1 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 you 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 construction of fine, multi strand 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 or 16 may be used for short runs of less an AWG equivalent of 18 or higher due to the power loss and degradation in performance that will occur. than ten feet. We do not recommend the use of cables with

The wire with the positive indication should be connected to the red terminals on both the PA5800/2.1 and your black terminal on the PA5800/2.1 and the speakers. speakers. The negative wire should be connected to the

If bare wire is used for connections, strip approximately ¾� (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 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 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 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. Once the wire has been attached to the banana plug following the plug manufacture�s instructions, simply insert the banana plug into the hole provided on the 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 left and right front or left and right rear (surround) speaker is identical, even though one 5

Cables that run inside walls should have the appropriate markings to indicate listing with UL (�CL-2/CL-3�), CSA (�FT-4�) or appropriate safety agency standards that may require in your area. Questions about running cables inside walls should be referred to you installer or a licensed applicable building or electrical code in your area.
