    Frequently Bought Together
    The Radial Pro DI is a high quality passive direct box that employs a proprietary transformer for both impedance conversion and isolation.The heart of the ProDI is a custom wound Radial transformer. It features an exceptionally high 140kΩ input impedance to reduce loading while enabling the ProDI to handle extreme signal levels at all frequencies without distortion. This is further improved upon with an internal MuMETAL® shield to protect against electromagnetic fields that can cause unshielded transformers to distort.The Radial Pro DI is ideal for acoustic guitars, bass, keyboards and drum machines.

    Radial Pro DI Features
    • Compact passive direct box for stage and studio
    • Able to handle huge transients without distortion
    • Transformer isolation eliminates noisy ground loops
    • Plug and play easy to use feature set – on stage or in the studio

    The Radial Pro DI features standard hi-Z input and thru-put 1/4-inch connectors, -15dB input pad and ground-lift switch. The balanced output is 600 Ohm to interface with professional snake systems and consoles. All switches are recessed in a protective zone to shield against damage from the road.

    Performance is amazing: linear from 20Hz to 18kHz, the ProDI features exceptionally low harmonic distortion and virtually zero phase distortion in the critical bass and mid zone, making it ideal for performance venues and studio work. Because of the transformer isolation, problems such as hum and buzz caused by ground loops are eliminated, making it very easy and hassle-free to use.
