• 4-channel full-range class D marine amplifier with integrated DSP, 100 W x 4 @ 2 Ω / 75 W x 4 @ 4 Ω - 14.4 V
• Designed to deliver premium audio performance in marine environments, each MVi amplifier combines our state-of-the-art NexD2 switching amplifier technology™ with an integrated, full-featured digital signal processor.
• Equipped 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 to 4 ohms and produces up to 200 W x 2.
• The NexD2 Full Range Technology™ in this amplifier is DSP-driven and features a reduced loop area design utilizing DirectFET™ outputs for excellent fidelity, very low noise and exceptional efficiency. The MV400/4i is housed in a compact cast alloy enclosure with a marine-grade powder-coated finish and equipped with corrosion-resistant hardware and connectors.
• Instead of conventional knobs and switches, all amplifier settings and DSP functions are configured via a compatible external device (PC, tablet or smartphone) on which the corresponding JL Audio TüN® software application is installed.
• The amplifier includes: Power connector (for 4 AWG cable), speaker output harnesses (2), 6-foot A/B USB cable

2nd generation NexD2 switching amplifier technology™.

• The advanced high-speed switching technology offers performance and efficiency at reference level.
• DSP-synchronized power supply and output channels produce first-class sound quality with very low noise and distortion.
  

Extremely versatile analog and digital inputs/outputs

• Differential balanced analog inputs accept a wide range of signal levels (up to 16 V RMS) and provide excellent noise rejection for clean, clear sound.
• Analog preamplifier outputs with fully independent DSP processing allow DSP functions to be shared with other amplifiers in the system (max. 4 V RMS)
  

JLid™ System Command and Control with network functions

• The proprietary JL Audio protocol provides a 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): Provides convenient activation of up to six DSP presets from the control station.
• MVi-HUB JLid-COMM and Network Hub: Provides network connectivity for up to six MVi amplifiers (one master and five slave amplifiers) for DRC control of the entire system and preset selection.
