There Is No Substitute for the Sound of PDR

Welcome the new digital PDR-Power series of Class-D amplifiers. The PDR-Power amplifiers incorporate many of Alpine’s best in class digital technologies, high performance and signature sound.

The PDR-Power amplifiers offer the best performance in their class, redefining expectations in the high-power 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.

Best Signal-to-Noise: In order to ensure that all of the industry-leading sound quality is heard at your ears, we’ve worked to create a platform that offers an unbelievably low noise floor, taking extra care to ensure a clean signal path, with no extraneous inferences.

Low Distortion: PDR-Power amps offer extremely wide and linear frequency response that results in unparalleled musical detail. Extremely low distortion means pure musical performance without audible artifacts to destroy your sound experience. Additionally, these amps have extremely high stereo separation and smooth phase response, which means more dynamic realistic imaging and staging for your total musical enjoyment. On the Mono side, best-in-class low distortion and tight control will give you clean, accurate bass response.

Unequaled Reliability

Excessive heat is the enemy of amplifiers and under extreme conditions will result in most amps shutting down completely. PDR-Power amps use a special Multi-Stage Power Management circuit that continuously monitors critical component temperatures throughout the amplifier and decreases power output if anything gets too hot. If you are playing music under heavy loads for long periods, the circuit automatically reduces power output slightly at first, and then further in a second stage if necessary. This two-stage approach provides seamless, interruption free listening experience for non-stop music playback.

Rotatable Illuminated Alpine Badge

PDR-Power amplifiers come with a rotatable illuminated badge that makes a very attractive presentation when mounted vertical or horizontally.

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.

Proven Power—Certified From Birth

All PDR-Power amplifiers are individually tested and have certified power ratings. Each amp comes with their very own verification certificate documenting its actual power output exceeds the rating by a wide margin.

Raising the Bar

The new V-Power products are now Class D digital amplifiers, resulting in a huge efficiency gain versus their predecessors without draining your battery or your pockets. Class-D provides continuous clean power to your speakers, operating at 80% efficiency far greater than conventional Class A or B amplifiers. Translation: Enjoy cleaner bass, even during extreme power demands.

Big Power, Small Package

V-Power amplifiers are known for their compact size, but don’t underestimate their power capacity. Although they have a 40% smaller footprint than their predecessors, they produce the same amount of power as before. Get the power you need, even if you have limited installation space.

Keep the Music Playing

The V-Power amplifiers provide reliable, stable thermal performance. They use a new, higher efficiency design to achieve non-stop music playback. A new circuit and heat sink design allows gradual thermal absorption and provides a gentle, almost undetectable power control.

Dual Feedback Modulation

Dual internal error correction technology – which had previously only been available in the PDX and X-Power amplifiers, is now integrated in V-Power mono amplifiers. The audio input signal is analyzed, compared, and corrected twice dynamically as the signal is processed through the amplifier. The result is amplifiers with the widest frequency response, higher damping factor, and lowest noise in its class.

Exceptionally Simple Sound Upgrade

The V-Power's 4-channel speaker level inputs connect directly to any head unit, without the need for external converters. This makes the V-Power amplifiers ideal for upgrading factory and aftermarket systems. The flush mount controls make for easy installation. The terminal covers conveniently snap-on without the need for additional tools, to protect the wiring connections while creating a clean, finished appearance.
