JS2™ & JS3™ Specifications

The Radial JS2 and JS3 mic splitters are passive devices that employ a Jensen transformer to perform the mic bridging and as such, all technical specifications show the isolated output. It is important to note that the JS2 and JS3 have been optimized for use at mic levels and each device is supplemented with MuMETAL® shielding and a solid steel enclosure to ensure minimal pollution from outside magnetic interference.
