Radial - 'JS3'
Passive 3-Way Microphone Splitter

Radial JS3

High Performance balanced
mic-level splitter
The Radial JS3 passive microphone splitter gives you maximum clarity thanks to the unique nickel-laminated core in the Jensen transformer. With incredibly low harmonic distortion and no bandwidth limits or phase shifts you won’t notice any sound difference when running this splitter in the signal chain.

The JS3 has more than 90dB of noise rejection and will save you from ground-loop interference making a positive difference to the sound of the microphone. This is a huge benefit when using the Radial JS3 in live sound situations if you needed to split a signal into three systems, like multiple mixers or multi track recorders. You can mount several JS3’s into the Radial J-Rak which makes it even more practical for live sound use.

Quality Features • Passive microphone splitter includes 1 through and 2 isolated outputs
• Signal path provides the best possible sound quality
• Comes with -30dB pad to cover for consumer line-level sources without overloading preamps
• Ideal for splitting 1 microphone to 2 destinations
• More than 90dB of noise reduction, with RF, DC voltage, and ground-loop noise rejection
• High-end Jensen transformer cancels any harmonic distortion, phase shifts, and bandwidth limitations

Sends Multiple Signals Simultaneously


Three way signal outputsThe JS3 makes it easy if you need to send the signal to three different outputs simultaneously. For example, when sending the signal to the main mixer, stage monitors and recording equipment at the same time.

The XLR input, two isolated outputs and direct output accommodates for this incredibly well, whilst eliminating any ground loops you may come across.
