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 VX800/8i 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 to deliver a powerful 200 W x 4.

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.

Amplifier includes: Power Connector (for 2 AWG wire), Analog Input/Pre-Out Harness, Speaker Output Harnesses (2), 6 ft A/B USB Cable.

TüN™ Software Applications

Intuitive setup and tuning, all at your fingertips. Automatically recognizes connected amplifier and displays appropriate interface. TüN™ is available for download for free in a variety of applications, for computers and most handheld devices.
