Detailed description
Detailed description
Designed for marine environments and motorized sports, the JL Audio MX500/1 monoblock amplifier is a compact Class D audio solution. It integrates JL Audio’s NexD™ switching technology, enabling efficient power delivery and high audio fidelity in a reduced form factor. This amplifier is optimized for 12-volt negative-ground electrical systems.
Audio performance and marine robustness
The MX500/1 amplifier delivers a continuous RMS power output of 300 watts at 4 ohms, 400 watts at 3 ohms, and up to 500 watts at 2 ohms at 14.4V. Its frequency response ranges from 20 Hz to 12 kHz (+0, -1dB), with a signal-to-noise ratio exceeding 97 dB at nominal power. Total harmonic distortion plus noise (THD+N) is less than 1% at 2 ohms, ensuring clear sound reproduction.
The marine-grade design features a corrosion-resistant die-cast aluminum chassis with a black powder-coated finish and a gasketed control cover. Stainless steel mounting hardware enhances durability. The unit is IPX7 certified, allowing it to withstand immersion in water up to 1 meter for 30 minutes, provided the control panel is properly closed.
Connectivity and advanced settings
The JL Audio MX500/1 features dual-range input sections, accepting both preamp-level (RCA) signals or high-level speaker-level inputs with switchable input voltage ranges from 250mV - 4V RMS (low) to 750mV - 15V RMS (high). Balanced differential inputs help reduce noise. It includes a variable low-pass filter from 40 to 400 Hz with a 24 dB/octave slope, as well as a variable subsonic filter from 20 to 40 Hz with a 12 dB/octave slope. A Bass Boost function adjustable from 0 to 12 dB at 43 Hz is also included.
Thermal protection is provided by an Advanced Rollback Protection system, preventing shutdowns due to overheating. A polarity reverse switch allows precise adjustments. For remote control of the subwoofer output level, the amplifier is compatible with the optional JL Audio M-RBC-1 remote level control (sold separately). Power requirements include a 50A external fuse (not included) and 4 AWG gauge wiring for power and ground.
