Detailed description
Detailed description
Designed for demanding marine environments, the JL Audio MV800/8i marine amplifier is an 8-channel audio amplification solution featuring a full digital signal processor (DSP) and JL Audio’s NexD2™ Class D switching technology, the second generation of high-speed switching technology.
Performance and Audio Processing
The JL Audio MV800/8i delivers a total RMS power output of 800 watts, distributed as 75 watts per channel at 4 ohms or 100 watts per channel at 2 ohms. In bridged mode, it provides 200 watts per 4 channels at 4 ohms. Its frequency response ranges from 12 Hz to 24 kHz (+0, -1 dB), with a signal-to-noise ratio of 99 dB and total harmonic distortion (THD) below 1%. The integrated 24-bit, 96 kHz DSP allows precise optimization of each channel via the JL Audio TüN™ app on PC, tablet, or smartphone. Adjustments include input routing, mixing, gain controls with clipping indicators, fully adjustable high-pass, low-pass, and band-pass filters (with selectable slopes from 6 to 48 dB/octave), a 10-band equalizer, phase and polarity control, and time alignment in 0.02 ms increments.
Marine Design and Connectivity
Its compact die-cast alloy chassis, coated with marine-grade powder and featuring corrosion-resistant connectors, ensures durability suited to marine environments. It has 8 configurable inputs for preamp/speaker level (accepting signals up to 16V RMS) with balanced differential inputs for effective noise rejection, and 4 processed analog preamp outputs (4V RMS). JLid™ connectivity enables integration of optional accessories such as the Network Hub, VXi-BTC Bluetooth communicator, or M-DRC-50 digital remote control. The amplifier also features automatic power-on via DC offset or signal detection, and advanced overheat protection through an innovative circuit. For IPX2 water resistance, vertical mounting with connections facing downward is recommended.
Installation and Technical Specifications
The amplifier dimensions are 355 mm (width) x 52 mm (height) x 176 mm (depth) with a weight of 2.54 kg (5.6 lbs). It is designed to operate with 12V DC negative-ground electrical systems and requires 4 AWG power and ground cables with an 80-amp fuse. Up to six sound presets can be stored for quick recall via the optional M-DRC-50.
