Radial JS3 Passive Mic Splitter - Your Ultimate Audio Splitting Solution
Passive 3-way Microphone Splitter
The JS3 is a high performance balanced mic-level splitter that lets you send a signal to multiple destinations simultaneously. It features two transformer-isolated outputs and one direct output, ensuring top-notch audio quality.
Portable and Versatile for Stage and Studio
The JS3 is the go-to professional mic splitter for splitting a single source to multiple destinations without any signal degradation or noise. Inside, a premium Jensen transformer provides galvanic isolation, getting rid of buzz and hum from ground loops. It also offers an extremely wide bandwidth with ultra-low distortion and phase shift. Ground lifts on the outputs further reduce noise, and the input pad allows line-level sources to be connected too. Both the JS2 and the JS3 can be rack mounted for touring and installation purposes, with up to eight fitting in the Radial J-Rak.
JS3 Applications
Feeding Three Mixers with Ease
When you need to feed the main mixer, stage monitors, and a recorder all at once, the JS3 makes it a breeze. With its XLR input, direct out, and two isolated outputs, it eliminates ground loops when connecting multiple mixers simultaneously.
