The Radial JS-3 is a Jensen Transformer-equipped mic splitter that allows a balanced source to drive multiple destinations via standard XLR connectors. This passive device features a premium nickel laminated core transformer for exceptionally low harmonic distortion without the usual phase shift caused by lesser steel core transformers.
The undisputed benefit of 100% transformer isolation provides better than -90dB common mode noise rejection (CMR), thus eliminating troublesome hum & buzz caused by stray voltage and ground loops. This ‘problem-solver’ offers a simple yet highly effective interface for microphones or direct boxes, and with the addition of the -30dB pad, consumer and line level devices may be employed without distortion or fear of overload due to saturation.
The Radial JS-3 mic splitter feature a rugged 14-gauge steel construction for maximum durability. A unique book-end design creates a protective zone for switches and connectors against the harsh environment of concert touring. An internal welded I-beam skeleton houses the PC board, creating a virtually indestructible monocoque design that makes it impossible to torque the circuitboard. This eliminates stress on the solder points which can cause cold solder joints to develop.
This innovative design also has the unique advantage of allowing up to 8 units to be rack-mounted using the Radial J-Rak. The J-Rak is a heavy-duty rack shelf that allows the splitters to span across a vertical array using only two 19” rack spaces. The Radial JS-2 and JS-3 mic splitters are easy to use, flexible and sound great!

Look inside a JS3 and you will find the build quality and components to be of only the highest professional standards. Radial's proven construction methods and materials ensure highest performance and years of trouble-free service.
The JS3 features a Jensen transformer – the best audio transformers in the industry – to achieve the highest possible signal integrity and phase coherence while eliminating hum and buzz caused by ground loops.
Features electrically isolated XLR I/O, Jensen transformer-equipped input, a second auxiliary direct throughput with ground lift, and two isolated output. Has a 30dB pad, supplies 48V DC phantom power for microphones, has a ground lift, and has common mode noise rejection up to -100dB at 60Hz. Features a stand-alone housing with 14-gauge, I-beam steel frame with baked enamel finish and an innovative bookend cover.
The JS2 and JS3 are designed to withstand the rigors of high- use professional environments! Radial's innovative 'book cover' design provides a protective zone around the switches and connectors that keeps these components safe.
Stress on circuitboards causes broken and intermittent solder joints, a common cause of failure in commercial rental and other high-use environments. Radial's 14-gauge welded I-beam inner chassis and 14-gauge outer shell greatly reduce the possibility of torque stresses being applied to the PC board.
A full-bottom no-slip rubber pad works double duty by (a) providing protection from electrical shock and (b) assuring that these splitters won’t slip and slide around.
