Essential Information on Radial JS2 and JS3 Mic Splitters
- Jensen Transformers for high-end signal separation, with exceptional reduction of harmonic distortion and phase shifts often associated with low-end transformers.
- Simple and efficient split for microphone-type signals or DI outputs, ideal for live, studio, broadcast, or event use.
- Built-in -30 dB pad to accept line-level signals and limit the risk of distortion or saturation.
- Two versions available: JS2 (2 outputs) or JS3 (3 outputs), with rack mounting option via the J-Rak (up to 8 units in a 2U rack).
A Radial Solution Designed for Clean and Reliable Signal Splitting
The Radial JS2 and JS3 fit within Radial's "field" approach: robust and straightforward tools designed to solve signal distribution issues without unnecessary complexity. Here, the focus is clearly on audio quality thanks to Jensen transformers, preserving the character of the source (mic or DI) while distributing the signal to multiple destinations with consistency and transparency suited to demanding environments.
Who Are the Radial JS2 and JS3 For?
These mic splitters are intended for sound engineers, stage technicians, studios, and service providers who need to send the same source to multiple pieces of equipment: for example, a mic signal to two or three mixers, or line-level signal distribution when the -30 dB pad is engaged. Whether for monitors, simultaneous recording, broadcast control rooms, or console redundancy, the JS2/JS3 provides a quick, clean, and repeatable solution.

Questions frequently asked
Does the Radial JS3 allow sending a microphone signal to three mixing consoles?
Its three XLR outputs enable distributing a microphone source to three devices, such as a front-of-house console, monitors, and a recording system.
What types of signals are compatible with the Radial JS3 splitter?
The XLR input accepts microphone-level signals as well as signals from a DI box. The -30 dB pad also allows handling line-level signals while reducing the risk of distortion.
Do the Jensen transformers affect the sound?
The Jensen transformers are designed to minimize harmonic distortion and phase shifts. The specified frequency response ranges from 10 Hz to 40 kHz, with a THD below 0.01%. This design preserves signal integrity during distribution.
Does the Radial JS3 require power?
It operates passively and does not require any external power supply.
Can multiple JS3 units be rack-mounted?
Rack mounting is possible using the J-Rak accessory, which can hold up to 8 units in a 2U rack space.
