Radial JS2 Splitter 1 In / 2 Out

A splitter designed for multi-mixing setups in live and studio environments

In sound reinforcement and production environments, it is common to need to share the same signal across multiple audio chains: front-of-house and monitor consoles, multitrack recording alongside live sound, broadcast/streaming distribution, or control room redundancy. This 1 input / 2 output splitter meets this need with a "studio quality" approach: the use of Jensen transformers and a design focused on isolation allow the device to be integrated into complex installations while preserving signal clarity.

Who is this splitter for, and in what applications does it make a difference?

This model is intended for sound engineers, stage technicians, service providers, and studios who want to duplicate a signal without compromise. It is suitable for both microphone signals (sharing a microphone between two mixers) and line-level signal distribution (keyboards, preamps, player outputs, stage monitors, sub-mixes, etc.). In live settings, it secures setups where multiple systems coexist (different power supplies, cable lengths, separate racks) by minimizing ground issues. In studios, it enables quick routing to multiple processing or recording chains while maintaining exemplary sonic coherence and stability.

Isolation, fidelity, and headroom: what Jensen transformers bring daily

Perfect isolation to eliminate ground loops

One of the most common problems when connecting multiple consoles or audio systems together is the appearance of ground loops, often audible as hum or unwanted noise. Thanks to perfect isolation, this splitter is designed to break these unwanted interactions between equipment. The result: a cleaner signal, faster balancing, and less time wasted tracking down noises that don't come from the microphones or the stage.

Audio quality: controlled bandwidth, phase, and distortion

To preserve the character of a microphone and the dynamics of a source, a splitter must remain neutral. Here, the specified frequency response of 10Hz - 40kHz +/- 1dB maintains solid low-end and open highs without compression or loss of detail. The phase shift under 2.8 degrees at 20Hz contributes to better coherence, especially on sources rich in low frequencies (kick drum, bass, piano, low voices), and on systems where multiple captures are combined.

Microphone and line-level compatibility with no surprises

This splitter accepts both microphone and line-level signals, making it versatile for both live and installed applications. The input headroom is specified at +2.0dBu at 20Hz (for 1% THD), helping to handle high-level signals in the low spectrum. Regarding distortion, the specification of 0.001% THD at 1kHz (and 0.05% at 20Hz) highlights a transparency-focused design, useful for preserving vocal intelligibility and transient definition.
