Single Cycle Control
Ground breaking technology applies output correction more than 400,000 times per second to deliver exceptional audio quality with reduced current draw and heat.
R.I.P.S. Technology
Regulated, Intelligent Power Supply is a tightly controlled design that maintains full power output from 1.5 to 4 ohms per channel and at any supply voltage from 11 to 14.5 volts.
Studio-Grade Signal Processing
Selectable 12 dB/octave (Butterworth) or steep 24 dB/octave (Linkwitz-Riley) filters with calibrated potentiometer to best integrate with subwoofers and component systems.
Differential-Balanced Inputs
A versatile design accepts speaker level signals without a line-output converter; it also delivers outstanding noise rejection while preventing alternator whine and other noises.
Advanced Rollback Protection
Innovative circuit design ensures that the amplifier will never shut down as a result of thermal overload and keeps the music playing, even under the most demanding conditions.
Built for the Elements
An all-aluminum, powder-coated housing with marine-grade hardware inhibits corrosion, and a watertight security cover protects all controls from the harshest of seasons.
Powerfully Neat
All MHD models share the same compact dimensions, making them far easier to place.
Realsink™ Chassis
The heat sink design requires no fans and permits stacking without losing cooling ability.
Designed To Fit
Removable power and speaker plugs aid installations in tight spaces.
