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%).
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 output.
Application Flexibility
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
cooling duties.
Speaker terminals
The
super high power speaker connectors allow for up to 10 mm² wiring and have a
unique quick disconnect design for simple error-free installation.
Power Connector
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.
Remote Control Bass Knob (RUX-KNOB)
Simply
add the RUX-KNOB (sold separately) and get full control from inside the dash for
remote on-the-fly bass adjustments. You also have the ability to control
multiple amps from just one controller with simple telephone cord adapters.
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.
