Product Information

When install space is at a premium, but your sound system demands plenty of power to realize its full potential, Polk’s super-efficient D Series amplifiers are a very cool solution. All D Series amps offer an ultra-compact, minimalist design available in 4-channel and monoblock configurations, as well as a big gun 5-channel beast that enables you to drive all your speakers and a subwoofer. Toroidal transformers help keep the amplifier’s sleek aluminum extruded design under 2 inches tall while ensuring plenty of clean, efficient power. Low THD’s, high signal-to-noise ratios rated at full power, plus wide bandwidths, make the PA D Amplifiers your high-performance choice for clean, distortion-free sound.

The PA D4000.4 amplifier is capable of bridging two full-range channels into a single full-range channel with higher output power. For instance, one front and one rear channel will increase the output power from 125W per channel to 400W per channel (for a 4-ohm load). The most common hookups for the PA D4000.4 would be four full-range channels, two full-range channels, and a bridged sub, or two bridged subwoofers.

Features:

  • Low THD, a high signal-to-noise ratio, plus wide bandwidth frequencies make the PA D4000.4 four-channel a superior choice for distortion-free power
  • Super-efficient class D design—Runs much cooler than conventional amps
  • High-speed MOSFET—switching power supply
  • Toroidal transformers help keep the amplifier’s sleek design under 2-inch tall while ensuring plenty of clean, efficient power.
