Three-way Jensen Transformer Passive Splitting

Radial's JS3 passive microphone splitter makes full use of the top-shelf clarity you'll only get from a Jensen transformer with a nickel-laminated core. With its extremely low harmonic distortion and freedom from phase shifts and bandwidth limitations, the only one who'll know there's a splitter in your signal chain is you. In fact, Sweetwater engineers have found that the JS3's greater than 90dB of noise rejection and protection from RF, DC, and ground-loop interference can seriously improve the sound of your microphones. That's a real bonus when you want to split a feed to three systems, such as a live mixer, a broadcast mixer, and a multitrack recorder. And when it comes to live sound applications, you can trust Radial Engineering's heroic build standards, which include an I-beam-style construction from 14-gauge steel. What's more, you can mount multiple JS3s in your Radial J-Rak.

Radial Engineering JS3 Passive Microphone Splitter Features:

  • Passive microphone splitter with 1 through and 2 isolated outputs
  • Ideal for splitting a single microphone to 3 destinations (e.g., main, monitor, and broadcast mixers)
  • Also great for splitting 1 microphone to 2 destinations (e.g., A/Bing mic preamps)
  • 100% discrete signal path provides the highest possible sound quality
  • Premium Jensen transformer eliminates harmonic distortion, phase shifts, and bandwidth limitations
  • Greater than 90dB of noise rejection, with RF, DC voltage, and ground-loop noise elimination
  • Includes -30dB pad to accommodate consumer line-level sources without overloading preamps
  • Radial's legendary build quality includes I-beam-style structure and 14-gauge steel construction
  • Fits in Radial's 4-slot J-Rak 4 and 8-slot J-Rak 8 x 19" rackmount chassis

Rated 5/5

Sounds great, doesn’t change sound

I used a condenser mic, with phantom supplied through the main pass through channel. Tested a reference preamp against a 40's tube pre and a 70's solid state preamp. Didn't hear any loss of high end, though of course you will lose a couple dB. Really the best option for repeatable tests.

Was able to null each option against my reference pre (a Forssell, very flat) and hear exactly what each was doing.

Excellent product.

Perfect split

My son uses the Radial passive Mic splitter in his recording studio. They are the perfect assesory that control the noise level of any microphone you use
Rated 1/5

Radial JS3

I returned this box. I found that it changes the tone and it lowers the volume a few db on all 3 outs. You lose high end as well.
