JS2 / JS3™ Development

Sometimes, developing a product is not so much a matter of innovation as it is convenience. The Radial JS2 and JS3 both fall into this category. They are problem solvers. The innovation really comes down to the fact that they can be rack mounted and grouped into any number of channels as may be required.

If you go back to the early days of Radial, the very first product we ever built was in fact a mic splitter. These were usually in the form of a multi-channel snake system for live touring. Over the years, we found ways of improving the performance of our mic splitters by shortening the distance from the input to the transformer, by adding noise filters to eliminate pollution from radio frequencies (RF) and by improving the mechanical performance of our enclosures. Some folks feel that our product is overbuilt. We hate fixing things. The JS2 and JS3 are grandchildren that have had a very strict upbringing!

A mic splitter normally has an input for the microphone and then a direct out. This is connected to the main console or mic preamp where phantom power can be turned on to feed a condenser. The isolated output will actually block DC while allowing the audio signal to pass.

We then asked ourselves how many isolated or split outputs would be needed? And the answer was clear as mud. For some, a single isolated output would be sufficient. For others, two isolated outs would provide noise free connections to three mixers at the same time. So... we made two models, the JS2 and the JS3.

Both units are equipped with one input and three outputs. The JS2 has a direct out plus a second output with aground lift. The third output is isolated via a Jensen JT-MBC transformer. The JS3 shares a similar direct out and two isolated outputs using the more expensive JT-MBD. Both deliver exceptional signal quality.
