Radial Engineering Ltd. J+4 User Guide
INTRODUCTION
Congratulations and thank you for purchasing the Radial J+4. This innovative signal
converter and line driver o󰀨ers options and performance designed for the touring
engineer, broadcaster, AV integrator and rental company that must regularly interface
consumer type audio equipment with pro-audio systems.
This manual contains all the information you need to start using the J+4 right away.
Although the J+4 is ‘plug and play’ easy to use, we suggest you read through it and
familiarize yourself with the features to get the most out of your J+4.
Should you have any questions, comments or concerns not covered in these pages,
please visit our web site and the J+4 FAQ section. This is where we post the latest
details and applications. If you do not nd what you need feel free to send us an
email at and we will do our best to answer your question as info@radialeng.com
quickly as possible.
OVERVIEW
The Radial J+4 is a stereo interface designed to accept consumer level -10dB
unbalanced high impedance signals and convert them to +4dB balanced low
impedance signals for easy manipulation in professional audio environments such
as broadcast, recording studios and live touring.
Careful attention has been paid to eliminate noise by combining the advantages of
active signal bu󰀨ering with transformer isolation. The J+4 delivers 100dB signal to
noise while ensuring hum and buzz caused by ground loops along with spurious
noise from digital clocking does not pollute the signal path. Controls include a stereo
level control, high pass (low cut lter) and ground lift. A selection of input connectors
include a stacked set of ¼" jacks for DJ mixers or keyboards, RCA’s for CD players
and a mini 3.5mm for smartphones making the J+4 convenient and quick to use.
As with all Radial products, the Radial J+4 is built tough to handle the most abusive
environments. A unique 14-gauge steel I-beam inner frame ensures the sensitive PC
board will not be subjected to outside stress which could potentially cause solder
joints to fail. An innovative book-end outer shell creates protective zones around
the sensitive controls, switches and connectors to further improve dependability
while a full bottom no-slip pad provides both mechanical and electrical isolation.
