JL Audio has unveiled the RD Series car audio amplifier line at its suite at The Palms Casino and Resort in Las Vegas. Four models are being announced for 2016, including two monoblock subwoofer amplifiers, a four-channel full-range amplifier and a five-channel system amplifier. All models are scheduled for delivery in the 2^nd quarter of 2016.

JL Audio Executive VP, Jeff Scoon said: “The RD project is all about increasing the value of our affordable car audio amplifiers. These new amps deliver innovative thinking in terms of circuit design, features, industrial design and mechanical design, and we couldn’t be more pleased with them.”

Circuit design for the RD project was led by JL Audio’s Senior Amplifier Engineer, Bruce Macmillan, and is based on JL Audio’s highly successful NexD™ Class D technology, which delivers outstanding sound quality, efficiency and reliability.

RD amplifiers also offer a very sophisticated input section, featuring JL Audio’s dual-range differential-balanced technology, for superior noise rejection and excellent compatibility with a wide range of input signal voltages. Automatic turn-on is also built-in, selectable between Signal Sensing and DC Offset Sensing modes. Convenient bridging switches are also provided for each stereo channel bank, eliminating the need for y-adaptors when bridging these channels.

Also on board, for the first time on a JL Audio amplifier, are LED clipping indicators. With the use of a CD or an audio file with a full-scale sine wave, installers can use these LED indicators to quickly establish the correct input sensitivity setting, without the need for additional test equipment.

All amplifier controls are accessible beneath a removable control cover, resulting in a clean look and security from unauthorized adjustment of the controls. Connections for speaker and power wires are via captured-wire connectors, with all screws protected by the control cover.
