Radial Engineering’s new Radial JS-2 and JS-3 are high-quality Jensen Transformer-equipped microphone splitters designed for use in professional live sound and studio environments.

The Radial JS-2 features a balanced input, a direct throughput, a second auxiliary direct throughput with ground lift and a transformer-isolated output. A 30dB pad is also provided when using the JS-2 with line-level devices. The direct output is used to drive the front-of-house (FOH) mixing console and is direct-coupled to allow 48-volt DC phantom return path to the microphone. A second auxiliary output is designed to drive a recording device or a transformer-isolated broadcast split. This output is equipped with a ground lift to minimize ground loops and to cut off 48V DC from phantom powering. The isolated output is bridged using a Jensen JT-MBC transformer. The JT-MBC is a 1:1,600-ohm transformer that is optimized for concert touring, and features exceptional common mode noise rejection with up to –100 dB at 60 Hz.

The Radial JS-3 is identical expect it employs a Jensen JT-MBD mic bridging transformer. The JT-MBD features a 1:1:1 with dual-secondary windings to allow dual-isolated outputs. This allows the JS-3 to be equipped with a main direct-out for FOH and two isolated outs for monitor mix and broadcast feed.

Both the Radial JS-2 and JS-3 employ electrically isolated XLR inputs and outputs, and feature a stand-alone housing with 14-gauge I-Beam steel frame with baked-enamel finish and a book-end cover. These combine to ensure the JS is never exposed to outside stress that could cause cold solder joints, while providing the switches and jacks with maximum protection against damage. For more permanent installations, as many as eight of the JS-2 and JS-3 may be 19-inch rackmounted using the 2RU Radial J-Rack shelf. This is accomplished by removing the book-end covers from the JS-2/3s and inserting these into a similar more compact housing. These are, in turn, mounted in the J-Rak with choice of front or rear positioning of the inputs.
