The PDR-Power amplifiers offer the best performance in their class, redefining expectations in the high-power compact amplifier category. Thanks to trickle-down technology, our in-house engineering team has taken many of the patent-pending technologies introduced in the industry-leading PDX series and infused them in the new PDR-Power amplifiers. The PDR-Power amps provide you with the absolute widest bandwidth, best signal-to-noise, lowest distortion and highest damping factor of any amplifier in their class without sacrificing power.

Dual-Feedback Modulation Loop
When playing music, a clean, distortion-free, low-power signal input to an amplifier should exit as an identical high-power output signal to drive your speakers. In reality, most amps don’t even come close to this ideal, instead adding significant audible distortion especially in the high frequencies, earning typical Class-D amplifiers a deserved reputation for bad sound. The PDR-Power’s Global Modulation with Adaptive Feedback Control loop circuitry intelligently assures the power output is as clean and distortion-free as possible. Their real-time error-correction analyzes the signal not only once, but twice by comparing input signal with the output throughout the entire amplification process. In doing so, PDR-Power amplifiers ensure that their output signal delivers a clean, clear and powerful sound that must be heard to be believed.

Small, Powerful Design
The new PDR-Power series amplifiers have decreased in size compared to the X-Power, yet they pack in much more flexibility, durability with Alpine sound quality.

Standing Alone in the Clarity Class
Ultra-Wide Frequency Bandwidth: This super-wide, industry leading frequency range offers listeners unparallel sound quality and detail that bests even the most high-end audiophile equipment.

Topside Controls and Adjustments
Topside controls on top of the PDR-Power amplifiers make installation and tuning easier than its predecessors. Just unscrew two fasteners and you’ll have access to all the controls needed to tune the amplifier. Their small size and versatile controls allow the PDR-Power amplifiers to easily be added to either an aftermarket or factory system and can be setup to accommodate a variety of system configurations.

Remote Sensing
The PDR-Power amplifiers will automatically turn on when voltage is detected on their speaker-level inputs, which makes them great for easy factory system upgrades.

Remote Control Bass Knob
Adjust subwoofer level without having to access the amplifier itself. Simply add the RUX-KNOB (sold separately) and get full control for remote on-the-fly bass adjustments. You also have the ability to control up to ten PDR-Power mono amps from just one RUX-KNOB controller with simple telephone jack adapters.
