This is How You Build a Really Cool Amplifier

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.

PA D4000.4 Features:

- 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 and will not corrode in humid

environments.
