Sound control pdx12/16/2023 See why professionals find the PDX series to be the #1 choice in best performing digital amplifiers. This super-wide, industry leading frequency range offers listeners unparallel sound quality and detail that bests even the most high-end audiophile equipment. The all-new PDX series amplifiers are not your typical class-D amplifiers. Traditionally, class-D amplifiers have not been known for both low distortion and wide frequency response. These new PDX amplifiers are the first ever class-D amplifiers to break tradition and trump the amps of yesterday. The PDX-M12, PDX-M6, PDX-F6, PDX-F4, and PDX-V9 are synonymous with extremely high resolution and detail. Uniquely PDX, distortion actually decreases at higher frequencies, resulting in a clean and clear signal where your ear is most sensitive to distortion. The PDX power supply delivers tremendous headroom with low distortion and noise. PDX amplifiers have an extremely high total system efficiency of ~80% (power supply is rated at >90%, output stage is rated >90%). These amps are stable at low impedances and are capable of their rated power from 2 to 4 ohms for all models. This allows excellent flexibility with multiple speakers and subwoofer loads and is adjusted automatically.Įach PDX amplifier comes with its very own birth-sheet. ![]() PDX amplifiers are tested and documented to show their true actual output. PDX amps incorporate Alpine’s new Power Management circuit. ![]() The Power Management Processor controls all aspects of amplifier performance, monitoring voltage, temperature, and output to ensure uninterrupted power output for non-stop listening. If the amp gets too hot, the Thermal Protection circuit kicks in and gradually decreases output power until it cools down.
