JL Audio MV400/4i 4 Ch. Class D Full-Range Marine Amplifier with Integrated DSP, 400 W
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
