JL Audio HD Monoblock Class D Wide-Range Amplifier

JL Audio MHD Monoblock Class D Wide-Range Marine Amplifier

JL Audio's Flagship Series of amplifiers offer unmatched performance from an ultra-compact chassis. These Class D amplifiers require less power, generate minimal heat and take up far less space than the common amplifier design. MHD Series amplifiers reproduce your music with outstanding accuracy, providing high-fidelity sound even under the most demanding conditions, thanks to a number of JL Audio exclusive technologies. Single Cycle Control (U.S. Patent #6,084,450), R.I.P.S System and Advanced Rollback Protection are just a few of the technologies that sets the MHD Series apart from the rest of the market, all designed to deliver top-flight audio performance. In addition, behind every MHD's removable security cover, you will find studio-grade signal processing with fully variable crossover filters to properly tune in your setup and put all the technology under the hood to good use.

Also included are JL Audio's noise-killing, highly flexible differential-balanced inputs with remote level control capabilities via the HD-RLC remote level control (sold separately).

Advanced Rollback Protection

JL Audio's signature Advanced Thermal Rollback protection system eliminates annoying thermal shutdown events to keep the music playing, even under the most demanding conditions. Should the amplifier reach an unsafe operating temperature, a special circuit rolls back peak power output, without changing gain, until the amplifier cools down to a safe operating temperature. The red "Thermal" LED will light to indicate this condition has been reached. Once the amplifier cools down, the circuit restores full peak power output and the red "Thermal" indicator reverts to its normal state. The operation of Advanced Rollback Protection is inaudible in most cases.


R.I.P.S. System

The MHD750/1 employs JL Audio's exclusive Regulated, Intelligent Power Supply (R.I.P.S.) design. This sophisticated power supply allows the amplifier to produce its optimum power (750watts x 1) over a wide range of speaker impedances. Unlike conventional amplifiers that require a specific impedance to produce optimum power, the R.I.P.S.-equipped MHD750/1 gives you the freedom to use a variety of subwoofer configurations without sacrificing power output or sound quality. The operation of the R.I.P.S. circuitry is entirely automatic and adjusts itself every time the amplifier is turned on according to the lowest impedance present at the speaker load.

JL is truly awesome

This amp is fantastic, especially for the size. It runs max power at all reasonable resistances and input voltages, has great thd spec, and doesn't get hot. (I ran my 10W7 pro wedge for about 4 hours at near max power and the amp wasn't too hot to touch.) It looks cool too.

Work horse

This amp is operating a 12" JL sub and it gets the job done. It gets the job done. I am satisfied with this purchase! Only had it for 4 weeks so I am not sure how durable it is but I'm sure if it lives up to the JL name it will be here for a while.
