NXD Class D Amplifiers


NXD125.4	NXD500.1

NXD250.4	NXD1000.1

Multi-Channel Performance

The 4 channel models feature full range Class D operation with direct feedback technology (DFT). Ultra high efficiency design with low heat dissipation for long term operation without thermal shutdown. The DFT circuitry allows for transparent sound from the input to the output stage of the amplifier. Acoustical performance that rivals conventional Class A/B amplifiers.

Class D with Boost Topology

The mono amplifiers feature Ultra High Efficient Class D operation. World's first 90% plus efficient car audio power amplifier. Operates with up to 2.5 times less heat dissipation vs. our competitors Class D design. The Ultra High efficient boost topology regulated power supply, provides long term operation without thermal shutdown and less stress on the car's battery.

Ultra High Damping Factor (UHDF)

The mono amplifiers utilize Ultra High Damping Factor (UHDF) providing smoother control of the woofers moving mass for tight hard hitting bass.

OE (Original Equipment) Integration

Want to retain the factory installed radio in your vehicle and add some power? No problem..... the NXD amplifiers provide the option of high level inputs for use with factory installed stereos. Additionally the amplifiers features a intergraded remote sensing circuit within high level inputs to trigger the amplifier "ON" once signal is detected.

Remote Level Control

(NXD250.4, 500.1 & 1000.1)

The overall level of the amplifiers can be adjusted remotely at the front of

the vehicle using the provided wired remote level control. The NXD250.4 provides the option for the remote to control channels 1&2, 3&4 or all channels.
