MHD Series 600w 4 Channel 24v Full-Range Amplifier - MHD600/4-24vFor 24v Systems Only150 W x 4 @ 1.5-4 OULTRACOMPACT AND ULTRAPOWERFULCombining our Single Cycle Control and R.I.P.S. power supply technologies, MHD amplifiers deliver world-class, full-range fidelity and high-power output from an incredibly small package. FeaturesHigh-fidelity Class-D design delivers superb sonicsIntelligently optimized for all the power - all the timeFull suite of studio-grade signal processing on boardUnique design adjusts operation to avoid thermal eventsExceeds international standards for salt fog and UV exposure3-Year WarrantySingle Cycle ControlGround 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. TechnologyRegulated, 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 ProcessingSelectable 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 InputsA 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 ProtectionInnovative 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 ElementsAn 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 NeatAll MHD models share the same compact dimensions, making them far easier to place. Realsink ChassisThe heat sink design requires no fans and permits stacking without losing cooling ability. Designed To FitRemovable power and speaker plugs aid installations in tight spaces.
