JL Audio VXi400/4i 4-Channel Amplifier with Integrated Digital Sound Processor

4-Channel Class D Full-Range Amplifier with Integrated DSP, 100 W x 4 at 2 Ohms / 75 W x 4 at 4 Ohms at 14.4V

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 VXi400/4i 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 Software application installed.

The amplifier includes: Power Connector (for 4 AWG wire), Analog Input/Pre-Out Harness, Speaker Output Harness, 6 ft A/B USB Cable
