JL Audio 4 Ch. Class D Full-Range Marine Amplifier - 98624

For 24V systems only: 4-Channel Class D Marine Full-Range Amplifier, 100 W x 4 @ 2 Ù / 75 W x 4 @ 4 Ù - 28.8V

This tiny amplifier packs a serious full-range punch, delivering a staggering 100 watts to each of its four channels into 2 Ù (28.8V, 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.

Use the M400/4-24V by itself to power two satellites, plus a subwoofer. With M-Series amplifier, the possibilities are endless.

The M400/4-24V 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. With the addition of an HD-RLC remote level control (sold separately), the amplifier's Ch. 1 & 2 level or overall level can be directly controlled from a remote location.

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.

This amplifier is designed for operation in vessels with 24 volt, negative-ground electrical systems. Use of this product in vessels with positive ground and/or voltages other than 24 V may result in damage to the product and will void the warranty.
