Get to know them!

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

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
