Status LEds (on top of amplifier): Power and Protection—Power will illuminate to indicate the amplifier is on and operating normally; protection will illuminate if the amplifier shuts down due to short circuit, DC offset, or overheating detected by onboard protection circuitry 2. HPF, FuLL, BPF Switch—Selects full range, high pass filter, or band-pass filter The HPF setting attenuates low frequencies and is used with mid-range speakers and tweeters The FULL setting does not attenuate any frequencies and is for full range speaker systems The BPF setting allows you to use both the high pass filter and low pass filter, and it is for use with mid-range drivers 3. (a) Low-Pass Frequency Button—Sets the frequency of the crossover at a range of either 50Hz - 500Hz or, when FREQ x 10 is engaged, to 500Hz - 5000Hz (b) LPF Variable Control—Adjusts the low pass filter frequency to attenuate frequencies above the setting on the control . 4. (a) High-Pass Frequency Button—Sets the frequency of the crossover at a range of either 20Hz - 400Hz or, when FREQ x 10 is engaged, to 200Hz - 4000Hz (b) HPF Variable Control—Adjusts the high pass filter frequency to attenuate frequencies below the setting on the control 5. Level Control—Adjusts the gain of the left and right channels to match the output voltage from your head unit 6. Line Level Inputs—Accepts line level input from a head unit, preamplifier or, equalizer 7. Line Level Outputs—Provides a full range signal for easy connection to additional amplifiers © 2011 Polk Audio—all rights reserved 6 © 2011 Polk Audio—all rights reserved © 2011 Polk Audio—all rights reserved 7 PA D2000.2 Power Inputs/Speaker Outputs 1. G ND (Ground)—Connect this terminal directly to the metal chassis of the vehicle, using the shortest wire necessary to make this connection. Always use wire of the same gauge or larger than the +12V power wire. The chassis connection point should be scraped free of paint and dirt. Use only quality crimped and/or soldered connectors at both ends of this wire. DO NOT connect this terminal directly to the vehicle battery ground terminal or any other factory ground points. 2. R EM (Remote Turn On)—This terminal turns on the amplifier when +12V is applied to it. Connect it to the remote turn on lead of the head unit. 3. +12V Power—Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery. WARNING: Always protect this power wire by installing a fuse or circuit breaker of the appropriate size within 12" of the battery terminal connection. 4. Fuse—These fuses (25A x 2) protect the amplifier against internal electrical damage and are meant to protect only the amplifier. All other power connections should be fused at the power source. 5. Speaker Output—Connect the speakers here. 6. Terminal Adaptor—The adaptor enables the use of cable up to 0000AWG for the ground and +12V connections (see illustration below). Amplifier Wiring Power Connections • PA D2000.2 Fuse Size: 2 x 25 AMP ATC. • Power connections accept up to 4 AWG wire. • 4 AWG power and ground wire recommended for optimal performance. • Connect +12V to the battery through fuse holder. This connection provides +12V main power to the amplifier. • Power wire must be fused within 12" of the battery. • Ground the amplifier using a good chassis ground as close as possible to the amplifier. • Connect REM terminal to remote turn-on lead from the head unit. This connection provides +12V power to turn-on the amplifier. • Add extra ground wire between the negative terminal of the battery and the chassis. Speaker Wiring Diagram PA D2000.2 The Polk Audio PA D2000.2 amplifier offers two positive and two negative output terminals for ease of connecting the speakers to the amplifier. The amplifier is stable to 2 Ohms per channel or 4 Ohms bridged. Bridging The amplifier is capable of bridging a left and right terminal into a single full range channel with higher output power. For instance, the L-/R+ channels when wired as shown will increase the output power from 125W per channel to a 500W channel (for a 4 Ohm load). The most common are shown in the figure above: two full range channels or a bridged subwoofer channel. Internal Bridging Terminals that can be used in bridging mode are identified by the black boxes next to each terminal. In the PA D2000.2, the two black boxes work together to create an internally bridged hookup. Amplifier Installation Mounting Locations The location of your amplifier will depend on several important issues. Due to the low profile and compact size of the Polk Audio PA D Series amplifier, there are many possible installation locations that will yield satisfactory amplifier performance. Always mount the amplifier in a place that protects the amplifier from the elements. In addition, mount the amplifier on a stable, flat surface. NOTE: Mounting amplifiers upside down is not recommended and may cause ...
