Accurate Dynamic Sound Reproduction
Alpine's goal is to deliver the best sound quality possible. With the PDX
series, digital switch-mode amplification yields incredible sound quality.
Advances in the PDX design include improved feedback circuitry to faithfully
reproduce the input signal for improved dynamic range and higher fidelity. If
you’re listening to your favorite rock song, your amp is ready to jump from
loud to calm and back again with ease.
Installation Flexibility
The PDX amplifiers' unique design allow for a clean, easy, and fast install
in your car! All the controls and wiring connections are in one convenient
location.
Save Space
PDX amplifiers are 60% smaller than previous models with the same output
power. Install your amps easily without sacrificing valuable room, power and
performance.
Smart Stacking
The PDX amplifiers feature a smart stackable design. All PDX amplifiers are
the same size, regardless of the amount of power or channel specifications.
Their exclusive design allows them to be stacked vertically on top of one
another. This is an industry-first installation option that saves a ton of space
in the trunk or under a seat.
Low Resistance, High Current Speaker Terminals
Quick disconnect plugs with low resistance and high current capabilities make
installing quick and easy.
More Power, Better Sound
PDX amplifiers deliver outstanding sound quality. The revolutionary design of
the PDX incorporates improved feedback circuitry and power supply filtering
system, plus a damping factor that is 350% better than Class A/B amps.
Unprecedented Sound Matching & Accuracy
A highly effective Powerful Feedback Circuit accurately compares the
amplifier's output against the original music signal. If there are any
differences found between the two, the feedback circuit automatically removes
the distortion in real-time! This keeps your music true to the original
recording without added distortion or filter noise.
Same Power Output - 2? or 4? Configuration
PDX amplifiers have the unique capability to deliver the same power output
regardless of 2? and 4? loads. This provides the ultimate in system flexibility
and subwoofer configuration diversity.
Power On Demand*
A combination of an advanced power supply, Class-D design, and switch-mode
digital amplification allow PDX amplifiers to stay extremely efficient at all
power levels. This produces less heat, eliminating the need for large heat
sinks, just another reason why they can be much more compact than conventional
amps.
The PDX amplifiers use Direct FETs device to make switch-mode digital
possible. Direct FETs are very small output devices that take up less room and
they switch on and off extremely fast when needed. Their ultra high-speed
switching capabilities allow them to perform at frequencies that other Class-D
amplifiers struggle to reproduce. This provides control over power consumption,
and cooler operation.
