Radial Engineering JS2 Passive Microphone Splitter Direct Box

The Radial Engineering JS2 Passive Microphone Splitter is a high-performance solution designed to split a single microphone signal into two isolated outputs without signal degradation. This direct box is perfect for live sound, broadcasting, recording, and professional AV applications where you need to send a clean microphone feed to multiple destinations. The JS2 leverages a custom Jensen transformer, known for its exceptional isolation and low distortion, which ensures that both outputs are free from interference, phase issues, or signal coloration.

A standout feature of the JS2 is its switchable ground lift, which can be applied to any of the outputs to effectively eliminate hum and buzz caused by ground loops. The transformer isolates each output, maintaining signal purity while preventing noise from being transferred across channels. This isolation makes it ideal for complex audio environments, where equipment from different power sources or buildings could potentially create interference.

Designed with durability in mind, the JS2 features a 14-gauge steel casing with an I-beam construction that resists torque and wear from frequent use. The unit also includes Radial’s book-end design, protecting connectors and controls to withstand rigors of stage and road use. This direct box is passive, meaning it requires no external power, which simplifies setup and enhances reliability.

The JS2 also offers a secondary direct output along with the isolated output, giving you multiple options for routing signals without needing additional equipment. Whether in a recording studio or a live venue, the Radial JS2 Passive Microphone Splitter provides audio engineers and musicians with a reliable, transparent, and durable solution for splitting mic signals cleanly and effectively.
