Alpine PDX-1.1000 - Mono Power Density Digital 1000w Amplifier

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.

Class-D amplification provides extremely high efficiency, with power losses much lower than with other types of operation. The PDX amps set new benchmarks for performance and accuracy. They use an advanced power supply, custom DSP processor and a true digital Class-D circuit for superior power production and efficient operation.
