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%).

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. If the amp gets too hot, the Thermal Protection circuit kicks in and gradually decreases output power until it cools down. Once cool, the power output automatically increases back to the previous level. If the circuit detects a Low Battery condition, it will gradually decrease power output if battery voltage becomes too low. Once the battery voltage increases, power will be restored. This interruption-free design allows for non-stop enjoyment with no hiccups or drop-outs, just clean, clear output.
