INPUT PANEL
1. -30dB PAD Allows line-level sources
to connect to the JS2s input.
2. Mic input For low impedance
microphone level signals.
3. Direct-1 thru balanced mic-level
direct output will pass phantom power
to microphone.
4. Bookend design 14 gauge steel
outer shell creates protective zone
around connectors and switches.
5. Full-bottom no-slip pad This
provides electrical isolation and plenty
of "stay-put" friction to keep the JS2
in one place.
OUTPUT PANEL
6. Direct-2 thru Duplicate balanced
mic-level direct output.
7. Ground lift (Direct-2 thru) Lifts the
ground pin-1 on the direct-2 thru XLR
connector.
8. Isolated output balanced mic-level
transformer-isolated.
9. Ground lift (Isolated output) Lifts
the ground pin-1 on the isolated output
XLR connector.
CONSTRUCTION
10. Steel I-beam enclosure eliminates
stress that could torque the PC board
and cause solder joint failure.
11. Military-grade double-sided PCB

WELCOME
Congratulations on your purchase of the Radial JS2 mic splitter. This simple yet
extremely handy device will likely nd its way into all types of applications such as
splitting mic signals and distributing signals throughout your sound system. The Radial
JS•2 is equipped with the world’s nest Jensen bridging transformer to ensure the
audio signal is transferred and distributed without distortion and is built using the nest
materials to ensure years of trouble-free performance.
We have purposely written this manual to be short, as most users will likely be
familiar with the JS2s applications. We do suggest that you take a moment to read
through this document to familiarize yourself with the features that are built in. For
more detailed information, please visit the Radial website. This is also where we post
questions and answers that come from users after the product is released. If you do
not nd an answer, we invite you to send us an email at info@radialeng.com and we
will do our best to answer your query in a prompt and professional manner.
The Radial JS2 is a wonderful device that will surely provide you with years of
problem-solving connectivity. Enjoy!
INTRODUCTION
Upon inspection, you will notice the Radial JS2 is equipped with four XLR connectors:
the MIC INPUT connector; the DIRECT-1 THRU; the ISOLATED OUTPUT with ground
lift switch and the DIRECT-2 THRU with ground lift switch.
Normally, the source microphone connects to the MICROPHONE INPUT and the
DIRECT-1 THRU connects to the mixing console that supplies phantom power back to
the microphone. If the source is a line-level device, such as a recording interface, the
input pad should be engaged to ensure the signal does not saturate the transformer,
causing distortion. Note that the JS2 will always output a mic-level signal
regardless of input level.
The JS•2’s isolated output will then feed a recording device, broadcast truck or other
PA system. The advantage of using the transformer-isolated output is that it creates
a magnetic bridge between the source and the destination, thus eliminating any
direct electrical current from passing. This eliminates problems such as ground loops
which can cause buzz and hum in a sound system. A ground lift switch is provided to
disconnect the ground path between the input and output to further suppress noise.
The DIRECT-2 THRU output is a direct output and is identical to the DIRECT-1 THRU
output, except that it is equipped with a separate ground lift switch. This would be used
to send a mic-level signal to an additional destination.
The beauty of the JS•2 is that it is completely passive. This means that it does not
require any power whatsoever to make it work. The magic lies in the quality of the
transformer we use. Jensen transformers are famous for their exceptional signal
handling and low distortion. The JS2 is equipped with a Jensen JT-MB-CPC mic-
bridging transformer that features a laminated nickel core and Faraday shield for
optimum signal transfer. You will nd the JS•2 to be transparent and very e󰀩cient,
making it the perfect choice in professional installations.
