 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.

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.

Protection�Thermal, DC offset, reverse DC voltage and short circuit protection.

 Nickel-plated wire terminals & RCA connectors�Ensure maximum signal transfer.

Front & rear level controls�Adjust the gain of the front and rear channels to match the output voltage from your head unit.

 Low-pass & high-pass frequency controls�Enables you to adjust crossover overlap for better blending of speakers.

 Front & rear BPF, FULL, HPF switches�Selects full range, high pass filter, or bandpass filter to dial in your speaker blending.

 Channel mode switch (ST/4Ch)�In the stereo position, the amplifier will send the same signal to front and rear channels.

Stainless steel hardware�Used throughout won�t corrode in humid environments.
