JL Audio revealed the new RD range of amplifiers at this years CES show in Las Vegas. The main aim of the project was to increase value through innovative use of circuit, industrial and mechanical design.
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.
