4-Channel Class D Full-Range Amplifier with Integrated DSP

The JL Audio VX400/4i is an ultra-compact, high-fidelity 4-channel amplifier from the premium VXi series. It is a dual-threat component, combining JL Audio’s second-generation NexD2 switching technology with a powerful, studio-grade digital signal processor (DSP). This allows it to act as both the "brains" and the "brawn" of your audio system, giving you total control over the acoustic environment from a single device.

The VX400/4i is designed to replace traditional knobs and switches with software-based tuning. Using JL Audio’s TüN software (available for PC, tablet, or smartphone), you can adjust every parameter—including parametric EQ, time alignment, and complex crossovers—with precision. Its DirectFET outputs and synchronized master clock ensure that the Class D amplification remains exceptionally clean and efficient.
