NX400.4 - 400 Watt Four Channel Amplifier

OE (Original Equipment) Integration

Want to retain the factory installed radio in your vehicle and add some power? No problem..... the NX400.4 provides the option of high level inputs for use with factory installed stereos.  Additionally the amplifier features a intergraded remote sensing circuit within high level inputs to trigger the amplifier "ON" once signal is detected.

DSP Netlink

Each NXS amplifier features unique DSP Netlink digital connections that allow networking of multiple amplifiers via standard RJ11 phone cable using proprietary technology. This makes adjustments of multiple amplifiers a breeze.  Lets say you want to have the NX400.4 running your mid/high speakers and a NX100.1 running your subwoofers. Each amplifier can be assigned a different network address so adjustments to both amplifiers can be made from remotely from a single NXLCDC or NXLI from the drivers seat of the vehicle.

Auto RCA Input Select

The NX400.4 allows for two or four channel input configurations.  This gives the flexibility of using only two channels of input and the amplifier automatically divides the signal internally for four channels of output (Non Fading).  The four channel input configuration offers normal independent operation allowing for front and rear fading capability through the head unit.

Multiple Output Configurations

The NX400.4 has the flexibility to  be configured for 2, 3 or 4 channel operation with stability to 2 ohms stereo or 4 ohm bridged mono.


Intelligent Remote Level Control
 The overall level of the amplifier can be adjusted using the NXLCDC or NXLC (sold separately). Unlike conventional level controls (Also known as Sub Level Controls), the NXS level control is an intelligent circuit allowing you to select which amplifier and/or channels  you would like to remotely control.  Additionally only one remote is needed to control multiple amplifiers.

The following example shows a NX400.4 amplifier with channels 1 & 2 running the mid and high speakers and channels 3 & 4 bridged running a single woofer. The level control has been turned “ON” for channels 3 & 4 so the woofer can be adjusted remotely by the level control (NXLCDC or NXLC).
