JL Audio MV800/8i MVi Series 8-Channel Marine Amplifier
Product Overview:
The JL Audio MV800/8i is a reference-grade 8-channel marine amplifier designed for boat owners who demand both power and precision. Part of the MVi series, it features integrated Digital Signal Processing (DSP) and JL Audio’s second-generation NexD2™ technology. This combination allows for professional-level audio tuning and exceptional efficiency in a compact, marine-ready chassis, eliminating the need for bulky external processors.
Key Features
Integrated Digital Signal Processing (DSP)
The standout feature of the MV800/8i is its built-in, full-featured DSP. Using the TüN™ software (available for PC, Mac, and mobile), you can optimize every aspect of your sound system. This includes time alignment with 0.02 ms precision, a 10-band parametric EQ per channel, and fully adjustable high-, low-, and bandpass filters with slopes up to 48 dB/octave.
2nd-Gen NexD2™ Switching Technology
Outfitted with NexD2™ technology, this amplifier achieves world-class sound quality with minimal distortion. The DSP-synchronized power supply and output stages use DirectFET™ outputs to maximize efficiency and reduce electrical noise. This ensures the amplifier stays cool and delivers clean power, even during long days on the water.
Versatile Output & Bridging
This 8-channel powerhouse is incredibly flexible. It delivers 75W RMS x 8 at 4Ω or 100W RMS x 8 at 2Ω. For systems requiring more muscle, it can be bridged to provide 200W RMS x 4 at 4Ω, making it ideal for powering a mix of high-performance speakers and subwoofers. It also features four processed analog preamp outputs to send tuned signals to additional amplifiers.
Marine-Grade Durability
Built for the elements, the MV800/8i features a cast-alloy chassis with a marine-grade powder coat and corrosion-resistant hardware. It carries an IPX2 water-resistance rating when mounted vertically with connections facing downward. Its differential-balanced inputs are designed to reject noise from the vessel's electrical system, providing up to 16V of input sensitivity.
