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.
PDX TECHNOLOGY INSIDE
Highest Damping Factor: With ultra-low output impedance, the new PDR-Power offers extremely controlled, tight bass for unprecedented sound quality. Damping Factor ratings are >1300 for Mono and >500 for full range models.
Sharper -24dB/octave slope: Ensuring that your sub plays longer, accurate and cool the new PDR-Power has a -24dB octave slope in the built-in low pass filter. A sharper slope to the subwoofer allows only the desired low-end frequencies play through your subwoofer.
