Combining 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.
Features
- HIGH-FIDELITY CLASS-D Design delivers superb sonics
- Intelligently optimized for all the power — all the time
- Full suite of STUDIO-GRADE signal processing on board
- Unique design adjusts operation to avoid thermal events
- Exceeds international standards for salt fog and uv exposure
- 3-YEAR Warranty
- Single Cycle Control: Groundbreaking 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.
