JL Audio XD300/1v2 - XDv2 Series Monoblock Class D Subwoofer Amplifier

This ultra-compact monoblock amplifier employs JL Audio's high-speed NexD switching design to achieve unprecedented efficiency and amazing power output for its size. It is small enough to fit in the tightest space applications, including motorcycles and ATV's (in a weather-tight compartment). Targeted specifically for subwoofer applications, the XD300/1v2 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50-500 Hz. The XD300/1v2 also features the v2 Spec feature set, which consists of automatic turn-on capability (via signal sensing or DC-offset sensing), and a dual-range differential balanced input section able to handle a wide range of input voltage levels. With the addition of an HD-RLC remote level control (sold separately), the amplifier's level can be directly controlled from the driver's seat. This amplifier features a black powder-coat finish and a gasketed, brushed aluminum cover for the controls. Its frequency response is limited to the range below 500 Hz. It is not designed for driving midrange speakers or tweeters. Every aspect of its operation has been optimized for low-frequency amplification.

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.


NexD Switching Technology

From the same minds that gave us the technology found in the 'Slash' amplifiers, JL Audio has taken the simple fixed Pulse Width Modulation design approach and enhanced it with a very high switching frequency: 240 kHz, which is about 4x higher than most Class D subwoofer amplifiers. This pushes the amplifier's bandwidth to at least 500 Hz with minimal distortion and improves efficiency, while keeping typically bulky circuity more compact. Your subwoofers will reward you with tight, rock-solid bass. These technologies allow XDv2 amplifiers to achieve efficiencies exceeding 80%, meaning far less heat and strain on your vehicle's electrical system than a conventional large amplifier.
