OVERVIEW

4-Channel Class D Full-Range Amplifier with Integrated DSP, 100 W x 4 @ 2 Ω / 75 W x 4 @ 4 Ω - 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 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.

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

Features:

Unprecedented, Onboard DSP Tuning Power!

  • Powerful DSP permits optimizing each channel’s timing, frequency response and output levels, for exceptional sound quality.
  • TüN™ Software delivers fast and easy setup, at your fingertips. Make all adjustments with a clear interface. Free TüN™ software is available for computers and most handheld devices.

2nd-Gen NexD2™ Switching Amplifier Technology

  • Advanced, high-speed switching technology delivers reference-grade power and efficiency.
  • DSP-synchronized power supply and output channels produce world-class sound quality with very low noise and distortion.

Ultra-Versatile Analog and Digital Inputs/Outputs


  • Differential-Balanced Analog Inputs accept speaker level signals up to 16V RMS, including those from factory systems. Delivers outstanding noise rejection to prevent alternator whine and other noises.
  • Optical Digital (Toslink) Inputs permit direct connection of S/PDIF digital sources, bypassing A/D converter. Accepts up to 24 bit/192 kHz input.
  • Analog and Digital Pre-Outs (pass-through or fully configurable): RCA Pre-Outs (4V RMS Max) and Optical (Toslink) Output at 24 bit/96 kHz
  • Automatic turn-on options via signal-sensing or DC-offset sensing

    JLid™ System Command and Control with Networking Capabilities

    • Proprietary JL Audio protocol provides control interface and all communication for VXi amplifiers and optional JLid™ accessories, including:
    DRC-100 / DRC-205 (Digital Remote Controllers): Offers convenient DSP preset selection and level adjustments from the driver’s seat.
    VXi-BTC Bluetooth® Communicator: Adds wireless connectivity for amplifier configuration from a compatible iOS® or Android® device.

    VXi-HUB Optical Network Hub: Provides network connectivity for up to six VXi amplifiers, allowing full-system DRC control and preset selection. Up to two VXi-HUBs can be daisy-chained to control up to ten VXi amplifiers.

    Download and test-drive all TüN® software versions in simulation mode for free (no VXi hardware needed).
