The Radial JS3 Passive Microphone Splitter is a precision-engineered solution for sending a single microphone signal to multiple destinations while maintaining pristine audio quality. Featuring a Jensen transformer with a nickel-laminated core, the JS3 provides extremely low harmonic distortion, no phase shifts, and wide bandwidth, ensuring that the only person who notices the splitter in your signal chain is you. Ideal for live sound, broadcast, and studio applications, it allows you to split a mic feed to three destinations — such as a main mixer, a broadcast mixer, and a multitrack recorder — without loss of clarity or signal integrity. Sky Music Australia highlights the JS3 as a reliable choice for engineers and performers who demand professional-level signal routing.

Built with Radial Engineering’s legendary attention to durability, the JS3 features an I-beam-style 14-gauge steel chassis that withstands the rigors of touring and studio use. The splitter includes switchable ground lifts to eliminate hum and buzz, as well as a -30dB pad on the input to accommodate consumer line-level sources. With over 90dB of noise rejection and protection from RF, DC, and ground-loop interference, the JS3 ensures clean, transparent sound even in complex audio setups. Multiple units can also be mounted in Radial’s J-Rak racks for convenient rack-based installations.
