JL Audio M800/8v2 800 watt 8 Channel Class D Full Range Marine Amplifier

JL Audio M800/8v2

800 watt 8 Channel Class D Full Range Marine Amplifier

Overview

This incredibly flexible amplifier packs a serious full-range punch and delivers a staggering 100 watts to each of its eight channels into 2 ohms (14.4V, 1% THD). The breakthrough that makes this much power possible in such a small chassis is our NexD™ ultra-high-speed switching design, which allows for full bandwidth Class D operation with extremely low distortion and outstanding efficiency.

The M800/8v2 includes a 12 dB / octave filter for each channel bank, which can be configured as a low-pass or high-pass filter and offers continuously variable cutoff frequency selection from 50-500 Hz. The M800/8v2 also features the v2 Spec feature set, which consists of automatic turn-on capability (via signal sensing or DC-offset sensing), and a dual-range differential-balanced input section able to handle a wide range of input voltage levels. With the addition of an HD-RLC remote level control (sold separately), you have the ability to control the level of two, four, or all eight of the amplifier's channel levels from the driver's seat.

Use it in one of many useful configurations:

• Eight-channel Satellite Amp: drive four pairs of speakers with 75 W x 8
• Six-Channel System Amp: drive front and rear satellites with 75 W x 4 @ 4Ω, plus two 4Ω subwoofers with 200 W each
• Staggered Six-Channel Satellite Amp: drive two speakers with 200 W x 2 @ 4Ω, plus four 4Ω speakers with 75 W each
• Big Four-Channel Satellite Amp: bridge to produce 200W x 4 @ 4Ω
• Four-Channel System Amp: drive left and right speakers with 200W x 2 @ 4Ω, plus two 4Ω subwoofers with 200W each

This marine amplifier features white and gray powder-coat finishes, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.

Technology

NexD™ Switching Technology
Summary:
NexD™ amplifier technologies produce exceptional audio quality, unsurpassed total efficiency and high power from very compact amplifier designs.

Advanced Rollback Protection
Summary:
JL Audio's exclusive Advanced Rollback Protection circuit monitors the amplifier's thermal condition and adjusts amplifier operation to eliminate annoying amplifier shut-down events.

v2 Spec
Summary:
An enhanced set of features added to XD and M-Series amplifiers that bear the "v2" designation make these models more versatile than ever.

Differential-Balanced Inputs
Summary:
JL Audio’s Differential-Balanced Inputs are engineered to combat induced cable noise, which is a common problem in car and marine audio installations. This technology allows for the use of conventional RCA cables, while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.
