JL Audio VX400/4i (D class) Full-Range power amplifier with Integrated DSP (4-channel).

100 W x 4 @ 2 Ω / 75 W x 4 @ 4 Ω - 14.4 V.

Designed to simplify great audio, every VXi amplifier combines our advanced NexD2™ switching amplifier technology with an integrated, full-featured digital signal processor.
With our second-generation NexD2™ technology, the VX400/4i full-range amplifier outputs up to 75 watts per channel into 4 ohms, or 100 watts into 2 ohms. 
It can also be bridged into 4 ohms, producing up to 200 W x 2.

The NexD2™ full-range technology in this amplifier is DSP-controlled and features a reduced loop area design utilizing DirectFET™ outputs for outstanding fidelity, very low noise and exceptional efficiency. 
The amplifier chassis is ultra-compact, with all connections on one side, to greatly simplify installation into tight spaces.

Instead of traditional control knobs and switches. 
All amplifier adjustments and DSP functionality are configured via a compatible external device (PC, Tablet or Smartphone) with the appropriate JL Audio TüN® Software application installed.
