Monoblock Class D Subwoofer Amplifier, 250 W x 1 @ 2 / 150 W x 1 @ 4 - 14.4V


Designed to produce a healthy 250 watts into 2 ohms (14.4V, 1% THD), the JD250/1 amplifier is a great solution for powering subwoofers in a cost-conscious system. Our proprietary NexD™ switching technology delivers large amounts of real-world power output with excellent efficiency and ultra-low distortion.

The JD250/1 s controls are located on the input panel while the power and speaker connections can be found along the opposite end of its extruded aluminum 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-balanced inputs are also on-hand, capable of accepting line-level and speaker-level signals. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set of preamp outputs so you can easily pass signals to another amplifier.

The JD250/1 is also equipped with an onboard LED-clipping indicator ring, surrounding the input sensitivity control. This useful feature lets you easily set your amplifier s input sensitivity, quickly and accurately, without special equipment. With the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer level from the driver s seat.


Technology

NexD™ Switching Technology

NexD™ amplifier technologies produce exceptional audio quality, unsurpassed total efficiency and high power from very compact amplifier designs.


Differential-Balanced Inputs

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.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
