Features

• The Alpine PDX Series is a recipient of the 2010 CES Innovations honors award. Every year at the world?s largest consumer technology tradeshow, the Consumer Electronics Show (CES), the Innovations Designs and Engineering Awards program recognizes the most innovative consumer electronics products, such as the PDX Series for the In-Vehicle Audio category.
• New Reference Grade Output Stage
• Ultra-Wide Frequency Response
• This super-wide, industry leading frequency range offers listeners unparallel sound quality and detail that bests even the most high-end audiophile equipment. 5Hz-100kHz for 4ch, 5Hz-400Hz for Mono (+0,-3dB)
• Total Harmonic Distortion Rate (THD) vs. Frequency
• The all-new PDX series amplifiers are not your typical class-D amplifiers. Traditionally, class-D amplifiers have not been known for high frequency reproduction..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, and PDX-F4 are synonymous with extremely high frequency reproduction. The THD is actually falling at high frequencies, resulting in a clean and clear signal where your ear is most sensitive to distortions. -<0.005% THD+N @ 1W, <0.05% THD+N @ rated power.
• Signal to Noise
• These amps are capable of unheard of S/N ratio up to 95dB S/N @ 1W, 122dB S/N at rated power for extremely clean, uncolored sound Forget unwanted background noise or static. The PDX amps deliver crystal clear music every time.
• Damping Factor
• With ultra-low output impedance, the new PDX offers extremely controlled, tight bass for unprecedented sound quality. Ratings are>1000 for Mono and>500 for 4ch.
• Power Output to the Extreme
• Beefed up Power
• 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%).
• Low Impedance Stability
• 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 speaker and subwoofer loads and is adjusted automatically.
• Certified Power From Birth, Guaranteed.
• Each PDX amplifier comes with its very own birth-sheet. PDX amplifiers are tested and documented to show their true actual output.
• Power Management Processor
• 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.
