How to choose
Choose a Radial DI by how many channels you need and whether your signal chain already has phantom power.
Beginner
A newer player recording at home can start with the single JDI, plugging an instrument straight into it before the signal reaches an interface. It needs no power and no settings, so setup is just a cable in and a cable out, and it can stay in a gig bag between sessions.
Intermediate
A gigging musician who runs both a guitar and a backup instrument benefits from the JDI Stereo, which handles two sources through one box, or the Pro48 if active electronics need 48v power on stage. Keep the unit off the floor where it can get kicked or rained on.
Expert
An engineer building a compact recording rig can use the USB-Pro to send two channels straight into a laptop without a separate audio interface. Route level carefully at the source since the box itself has no gain control, and store it in its case when travelling between studios.
