WHAT YOU'LL LOVE
BIG POWER, SMALL SIZE
Small size, minimal heat and lots of power — Class-D amplifier design with innovative JL Audio switching technology applies output correction more than 400,000 times per second to deliver exceptional audio quality with reduced current draw and heat.
MAX POWER AT ANY VOLTAGE OR IMPEDANCE
In both the 750- and 1200-watt HD monoblock versions, our tightly controlled Regulated, Intelligent Power Supply design maintains full power output from any impedance between 1.5 and 4 ohms per channel and at any supply voltage from 11 to 14.5 volts.
STUDIO-GRADE SIGNAL PROCESSING
Selectable 12-decibel/octave (Butterworth) or steep 24-decibel/octave (Linkwitz-Riley) filters with calibrated potentiometer make it easy to extract optimum performance from your subwoofer.
ADVANCED ROLLBACK PROTECTION
A proprietary protection circuit monitors the amplifier's thermal condition, rolling back peak output power until the amplifier cools down to a safe operating temperature.
FLEXIBLE MOUNTING OPTIONS
For single or multiple amplifier installations, standard mounting screws with corner caps and lateral mounting feet are provided. An optional stacking kit is also available for mounting one amplifier atop another.
AUDIO TECHNOLOGIES
DIFFERENTIAL-BALANCED INPUTS
Combating induced cable noise, this technology allows for the use of conventional RCA cables while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.
REALSINK™ CHASSIS
Using vertical cast-alloy fins to dissipate heat effectively, the RealSink design requires no noisy fans and permits stacking without losing cooling ability.
R.I.P.S. POWER TECHNOLOGY
Regulated, Intelligent Power Supply is a technology designed to adjust the amplifier's operation and ensure full and consistent power delivery over a wide range of battery voltages and load impedances.
SINGLE CYCLE CONTROL™ TECHNOLOGY
Innovative JL Audio switching technology applies output correction more than 400,000 times per second to deliver exceptional audio quality with reduced current draw and heat.
