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

Engineered to deliver reference-grade audio performance in marine environments, every MVi amplifier unites our cutting-edge NexD2™ switching amplifier technology with an integrated, full-featured digital signal processor.

Outfitted with our second-generation NexD2™ technology, the MV400/4i produces up to 75 watts per channel into 4 ohms, or 100 watts into 2 ohms. It can also be bridged into 4 ohms, generating 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. Housed in a compact, cast alloy chassis with marine-grade powder coat finish, the MV400/4i is outfitted with corrosion-resistant hardware and connectors.

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), Speaker Output Harnesses (2), 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 a wide range of signals levels (up to 16V RMS), offering outstanding noise rejection for clean, clear audio.
  • Analog Pre-Outs, with fully independent DSP processing allow sharing DSP capabilities with other amplifiers in the system (4V RMS Max)

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:

  • VXi-BTC Bluetooth® Communicator: Adds wireless connectivity for amplifier configuration from a compatible iOS® or Android® device.
  • M-DRC-50 (Digital Preset Controller): Offers convenient activation of up to six DSP presets from the helm.
  • MVi-HUB JLid-COMM and Network Hub: Provides network connectivity for up to six MVi amplifiers (one master and five slave amplifiers) for full-system DRC control and Preset selection.
