JL Audio RD500/1 #98618 Mono Subwoofer Amplifier
Born to produce a whopping 500 watts into 2 ohms (14.4V, 1% THD), the JL Audio RD500/1 amplifier was engineered to generate tons of pure subwoofer bliss from a sleek, ultra-compact chassis. The secret behind its power proficiency is our proprietary NexD™ switching technology, which delivers large amounts of power output with precise efficiency and ultra-low distortion.
For your convenience, the JL Audio RD500/1’s controls are located on top of the amplifier, beneath a protective cover, with all connections found along one side of its chassis. Signal processing features include a 12 dB / octave low-pass filter, with continuously variable frequency selection from 50-500 Hz, and a variable bass boost EQ. Dual-range, differential-balance inputs are also on-hand, capable of accepting most input voltage levels. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set preamp outputs so you can easily pass signals to another amplifier.
The JL Audio RD500/1 is also equipped with an onboard LED-clipping indicator. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity setting, quickly and accurately, with no special equipment needed. The RD500/1 features a durable, black powder-coated finish and a top-mounted LED light strip that reports the overall status and condition. With the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer output directly from the driver’s seat.
Power your bass
JL Audio’s RD500/1 mono amplifier will power your subwoofer with up to 500 watts RMS, so you’ll hear and feel the bass clearly over the whistle of the wind and rumble of the road. An optional wired remote lets you adjust the sub’s volume from your front seat.
NexD Switching Technology
NexD amplifier technologies produce exceptional audio quality, unsurpassed total efficiency and high power from very compact amplifier designs
JL Audio’s Differential-Balanced Inputs are engineered to combat induced cable noise, which is a common problem in car and marine audio installations. 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.
Low current demand, low distortion, and integrates well
The RD500/1 plays your music with true fidelity and impressive impact, without straining your car’s electrical system, thanks to JL Audio’s proprietary NexD™ amplifier technology. “Differential-balanced” inputs keep the incoming signals clear of outside noise, and allow you to connect this amp to just about any radio. The speaker-level inputs feature two auto turn-on modes so you can readily incorporate this amp into a factory system — no need for RCA connections or a remote turn-on lead for this setup.
LED clip light and other cool features
A low-pass filter and bass boost help you dial in the perfect tone for your sub and enclosure. An onboard LED clip indicator lets you set the amp gain quickly and accurately with the use of a test tone. A removable cover hides the amp’s controls, resulting in a handsome appearance and a tamper-resistant installation. Cool blue LED accent lighting adds some charm to this amp’s rugged good looks.
