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 @
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.
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.
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
Unique Stacking System
The new PDX series amplifiers are 20% thinner than previous
models at only 2” thick. New stacking system packs the amps
closer together so there are no gaps and to save space in the
trunk while directly coupling the amps heatsinks to help share
The super high power speaker connectors allow for up to 10 mm²
wiring and have a unique quick disconnect design for simple
The new removable connector features a low-loss, high-current
design. It accepts up to 25 mm² wire, to ensure your amp gets
the power it needs while allowing for easy installation.
A Touch of Personalization
PDX amplifiers come with easy-to-remove trim rings, so if you
would like to customize them, you can have them painted. Add it
as another Do-It-Yourself project, or leave it to professionals
and ask an Authorized Alpine installer near you. The removable
trim ring can be custom painted to match your vehicle or
personalized to anything you want.
