JS2/JS3 Passive Microphone Splitter

Part no. R800 1022 ~ JS2 single isolated output Part no. R800 1023 ~ JS3 dual isolated outputs
  • Jensen® transformer-equipped for optimal signal transfer
  • Choice of 2-way or 3-way designs for extra flexibility
  • Compact design, up to 8 may be rack mounted in a J-Rak™
  • Ultra rugged 14-gauge steel construction for added durability

The Radial JS2 and JS3 are high performance balanced mic level splitters that let you split a signal and feed multiple destinations at the same time. 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.

Two units are offered: The JS2 is equipped with one isolated output while the JS3 has two. 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 JS2 and 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 JS2 and JS3... split the mic signal without compromising your sound.

JS2/JS3™ - Applications
Using the JS2 for a 2-way split

The Radial JS2 is the perfect interface for splitting a microphone to feed more than one mixer at the same time. 100% isolation eliminates potential ground loops between the two consoles for quiet performance. The main output provides a 48V phantom power return path to the mic.

Using the JS2 to compare two mic preamps

In the studio, it is often advantageous to compare the sound of two mic preamps on a particular voice. The JS2 is ideally suited for this as it will not color the sound of the mic or add distortion. The plug & play simplicity makes set up quick.

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 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.
