Alpine PDR-V75, PDR Series 5-Ch Class-D Car Amplifier - 100W x 4 + 350W x 1

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
