Superior to Any Other DI in this Price Range!

The Radial Pro DI is a high-quality, full-range passive mono direct box equipped with custom made audio transformers for exceptional signal handling without saturation and with extremely low phase distortion in the critical bass and mid regions. The result is exceptional clarity and definition at an attractive price point. You will find that with acoustic guitars and basses, the natural tone of the instrument will shine through with a smooth and musical rendering. For electrically powered devices such as keyboards, the ProDI will immediately eliminate troublesome ground loops while delivering solid dynamics with a full rich sound.

Features:

  • Full range passive direct boxes
  • Isolation transformer eliminates noise
  • Very low harmonic and phase distortion
  • Compact and rugged design
  • Ideal for live sound and studio

We use several of these and the ease of set up and push button control of the lift make it easy to eliminate noise issues.
