JL AUDIO MHD750/1 - Marine Class-D MONOBLOCK

MHD750/1
Monoblock Class D Marine Wide-Range Amplifier, 750 W x 1 bei 1.5-4 ohms

This ultra-compact monoblock amplifier employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 750 W of clean power into any impedance between 1.5 and 4 ohms, giving you the highest degree of flexibility in designing your subwoofer system.

Tight power supply regulation keeps distortion ultra-low and maximizes your bass performance. While targeted primarily to subwoofer applications, the MHD750/1 is a full-range amplifier and can also be used to drive high-performance mid and high frequency speaker systems.

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.
