Radial OX8J

Essential Information About the Radial OX8 Microphone Splitter

• 8 channels in a 1U rack to duplicate a mic or line signal to multiple systems, both live and in fixed installations.


• Jensen transformers per channel (JT-MB-CPC) for reliable isolation and clean signal transfer.


• 3 outputs per channel: direct output with phantom power pass-through, direct output with ground lift, and transformer-isolated output for recording.


• 100% passive: no power supply needed, ensuring simplicity and reliability on stage.

A Radial Splitter Designed for Stage and Rack Integration

Designed in a 1U rack format, the Radial OX8 meets the practical needs of control rooms and stages: distributing the same signal to multiple destinations without complicating cabling or multiplying boxes. Its very robust design (1.55 mm steel chassis) suits both touring environments and technical racks in fixed installations, where stability and simplified maintenance are priorities.

Radial's approach remains true to a "field" logic: connectors adapted for professional use, immediately accessible controls, and a passive architecture that avoids any dependency on external power.

Who Is the Radial OX8 For and When to Use It?

The Radial OX8 is ideal if you need to send a microphone (or line-level source) simultaneously to multiple systems, such as a front-of-house console, monitor console, and multitrack recorder. It is particularly relevant for concerts, recording, conferences, broadcast, or whenever a backup plan is required.

Thanks to its multiple outputs, you can organize a clear distribution: the main console receives the direct signal with phantom power if needed, monitors benefit from a second direct output with ground lift, and the recorder gets an isolated output to minimize hum, ground loops, and equipment interaction.
