The Radial JS3 Microphone Splitter is a high performance balanced mic level splitter that lets you split a signal and feed multiple destinations at the same time. Equipped with two isolated outputs and a premium Jensen transformer, the JS3 is easy to use, flexible and sounds great!

The Radial JS3 Microphone Splitter's typical applications include splitting a signal in the studio to feed more than one preamp, feeding a stage mic to more than one mixing console, or even splitting the signal to a live PA during a broadcast event.

The Radial JS3 is equipped with two isolated outputs. The engine inside both units is a premium Jensen transformer. It features a nickel laminated core for exceptionally low harmonic distortion without the usual phase shift and limited bandwidth typically introduced by lesser designs. The Radial JS3 deliver better than 90dB of noise rejection, eliminating troublesome noise caused by stray DC voltage and hum & buzz caused by ground loops. The signal path is 100% discrete and incorporates RF filtering for even greater noise suppression. These 'problem-solvers' offer a simple yet highly effective interface for microphones or direct boxes, and by engaging the built-in -30dB pad, consumer and line level devices may also be connected without distortion or fear of overload due to saturation.

As with all Radial products, both mic splitters feature rugged 14-gauge steel construction for maximum durability. A unique book-end design creates a protective zone for switches and connectors against the harsh environment of concert touring while the internal I-beam frame makes it virtually impossible to torque the PC board which could otherwise compromise the sensitive solder joints. The innovative design also has the unique advantage of allowing up to 8 units to be rack-mounted using the Radial J-Rak™.

The Radial JS3... split the mic signal without compromising your sound.

Radial JS3 Microphone Splitter Applications

  • Using the JS3 to feed three mixers - Sometimes, you need to feed the main mixer, stage monitors and a recorder at the same time. The Radial JS3 makes hook-up easy with XLR input, direct out and two isolated outputs. These eliminate ground loops when connecting multiple mixers at the same time.

    Radial JS3 Microphone Splitter is awesome!
    Bill- Yetti

    The JS3 is such a great box, more than just a mic splitter, but the ability for COMPARING 3 different mic preamps at the same time. Also the ability to use your favorite mic pre insert, and split that output signal to both your DAW and to a X-Box (reamp box) for real time recording of both.

    Radial JS3 Microphone Splitter

    Does what the manufacturer claims. No signal degradation that I can tell. A bit on the expensive side, compared to some other mic splitters, but it works as advertised so the money wasn't wasted (can't say that about all my sound- equipment purchases unfortunately!). Appears to be a good quality item. I bought three of them and hope to eventually purchase five more and build a rack of eight using Radial's optional rack assembly.
