Product Description

Low Resistance, High Current Speaker Terminals

When you disconnect an amp it is hard to connect again because you don’t know the polarization, but the PDX amps eliminate that problem. You just plug the speaker cables into the terminals – you can’t do anything wrong.

Error-free connections.

Much faster and easier.

Small Footprint

The illustration shows how amazingly compact the PDX amplifiers are as compared to the previous MRD-M1001.

About 60% smaller than previous models with same power output.

Makes it possible to build a serious sound system with powerful bass — without filling up the boot!!

Same Power Output into 2Ohm and 4Ohm

The ability to provide the same output to 2Ohm and 4Ohm provides greater system building flexibility.

Mono amp has two subwoofer connectors, making it easy to add a second subwoofer.

Same amount of power used to drive one 4Ohm speaker can drive two 4Ohm speakers when they are wired in parallel to create a 2Ohm load.

Excellent Sound Quality

In the PDX-4.150 and PDX-2.150, Alpine met the challenge of producing a full range digital amplifier to rival the sound quality of even the best high-end Class A/B amplifiers. They use improved feedback circuitry to faithfully reproduce the input signal for improved dynamic range and higher fidelity. A revolutionary power supply filtering system, lower switching frequencies and lower output impedance combine to create extremely low distortion and greater speaker control, for clarity that meets or exceeds that found in the best Class A/B amplifiers. All three amps benefit from the use of trickle down technology from the AlpineF#1Status amplifier.

Amazing Power Density Ratio

Alpine’s goal is to give customers powerful amps that take up a minimum of space, and this has been achieved as never before with the PDX amps. We have even developed a new way to measure this performance, called the Power Density Ratio. To find it, divide the total RMS power from all channels by the total displacement volume of the amplifier in cubic centimeters (WxDxH).

The PDX-1.1000, for example produces an impressive 0,27 watts per cubic centimeter. Competitors only achieve a Power Density Ratio of about 0,13. The PDX-1.1000 is also extraordinarily small and efficient. In fact, the power supply is so efficient that the amp does not need a heat sink. All the power goes into output, not heat.

Layered Installation

All of the new PDX series amplifiers share an identical form. Using the removable 1” diameter trim caps from the top of the amplifiers, the amplifiers can be vertically stacked on top of each other and share one set of mounting holes — an industry-first installation option.
