Installation Flexibility The PDX amplifiers unique design allow for a clean, easy, and fast install. All the controls and wiring connections are in one convenient location. Save SpacePDX amplifiers are 60% smaller than previous models with the same output power. Install your amps easily without sacrificing valuable room, power and performance. Smart StackingThe 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. Low Resistance, High Current Speaker TerminalsQuick 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 MatchingAccuracy A highly effective Powerful Feedback Circuit accurately compares the amplifiers 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. *Full Range PDX Amplifiers Only (PDX-4.150, PDX-4.100, PDX-2.150 PDX-5)
