INTRODUCTION
This user guide covers the installation and operation of the Radial OX8 microphone splitter. We recommend that you take a few min-
utes to read through this manual in order to familiarize yourself with the many innovative features that are built in.
Should you have questions or applications not covered in this manual, we invite you to visit the Radial website at www.radialeng.com
to check the FAQ section for the latest updates. Of course, you can also send us an email at support@radialeng.com.
OX8 DESIGN CONCEPT
The Radial OX8 is an eight channel, balanced microphone splitter in a compact 1RU package that divides the mic signals three ways;
to a direct output; a direct output with ground lift; and an isolated output. A high performance bridging transformer is used on the iso-
lated output to eliminate hum and buzz caused by ground loops.
Splitting microphone signals is a straight forward concept. It’s most common in sound reinforcement and live recording when the on-
stage microphones must be split to feed two mixing consoles. When done improperly, splitting a signal can dull frequency response,
lower the output and worst of all, cause ground loops that produce buzz and hum. To avoid these pitfalls, sound reinforcement com-
panies have been building custom “splitter-snakes” for many years.
The OX8 is an off-the-shelf splitter for the rest of us allowing virtually anyone to design and assemble a splitter-snake with plug-n-play
simplicity and professional audio quality without the need for custom metal work or complex soldering.
