Features

PDX Amplifier Design: Class-D amplifiers boast higher efficiency, produce much less heat, and draw less current than traditional Class-AB amps. The PDX series is Alpine's totally new super-efficient power density design of full range class-D amps. They combine MOSFET power supplies, MOSFET final outputs, and a thermal management processor, along with a 4-Layer Glass Epoxy PC Board to create a high-end sound quality without the bulky heat sinks required by most amps with this much power.

STAR Topology: Alpine's unique STAR (Signal Transit for Accurate Response) Circuit PCB design provides a single common ground for all amp sub-blocks, preventing ground interference and minimizing internal noise.

Terminal Layout: For wiring convenience all the inputs and outputs on the amp are on one side.

Verification Certificate: The amplifier comes with a certificate that lists the RMS power output of the individual amplifier. It also lists the model number, serial number, test date, and the test conditions (14.4 volts, 4 ohms).

Speaker Connecters: The PDX series amps use a new Speaker Quick Connect plug to attach the speaker wires to the amp. Bare speaker wire, up to 8 gauge, is held in place by a set screw, the Quick Connect plug then plugs into the amp. Like an RCA jack, the Quick Connect plug uses a center positive layout, so it fits two ways and both maintain correct polarity.

Stack Amps: Because the PDX series design generates so little heat, up to three amps can be stacked and bolted together. All three amps in the series, PDX-2.150, PDX-4.150, and PDX-1.1000 share the same footprint, so they can be stacked together.

Notes: When stacking multiple amplifiers, do not install vertically or at an incline. Any stack installation other than parallel to the vehicle floor, invalidates the warranty.

LED: The top mounted LED Power/Status indicator glows blue when operating normally and red when one of the protection circuits engages.

Protection Circuits: This amplifier includes protection circuits to prevent damage due to the following conditions:

  • ambient temperature too high
  • supply current too high
  • short to ground
  • over voltage

Controls

Controls (front of unit): Once set, the controls are covered by a door.

  • Crossover Mode switch: set to HP (high pass), OFF (full range) or LP (low-pass)
  • Crossover Frequency: rotary control used to select the crossover frequency, variable from 30 to 400Hz
  • Gain control: rotary control used to set the amplifier's gain according the level of the incoming signal, continuously variable from 0.2V to 4.0V

Connections

Inputs and Outputs (rear of unit):

  • Power and Ground terminals: power and ground terminals are gold plated set screw terminals, will accept up to 4 gauge bare wire, Alpine recommends 6 gauge wire minimum
  • Remote Turn-on terminal: gold plated set screw terminal, will accept up to 10 gauge bare wire
  • Speaker terminals: each speaker output uses Alpine's Speaker Quick Connect plug
  • Line Level Input: Left and right female RCA jacks, gold plated
