Radial Engineering

Description

The Radial JDI MK3 is considered by many to be one of the finest passive-operation direct boxes available. It employs a Jensen isolation transformer for optimum audio performance. 60-cycle ground loop elimination and adept handling of high-output, active instruments and keyboards make it discrete and versatile. The Radial DI Box has a steel I-beam construction, baked enamel finish, and protected faceplate that mean it's built to survive.
