Radial ProD2 Stereo Passive Direct Box

Stereo Passive Direct Box

The ProD2 is a 2-channel passive direct box designed to connect stereo keyboards or high output instruments to a PA system or home recording setup without noise or distortion.

The ProD2 is a high-quality ultra-compact stereo passive direct box that features custom-made Radial transformers. Essentially two ProDIs in one compact enclosure the ProD2 is a great choice for stereo keyboards, DJ equipment and consumer hi-fi systems. Its high-performance transformer has an exceptionally linear frequency response from 20Hz to 18kHz and is able to handle high signal levels without saturation making it ideal for electronic instruments. The ProD2 is housed in an extremely rugged two piece 14 gauge steel enclosure with a book-end designed outer shell that prevents damage to the switches, features a -15dB PAD for high output sources and ground lift switch to troubleshoot noise from ground loops.



  • Stereo direct box designed for keyboards
  • Smooth, warm sound rounds out digital edge
  • Able to handle huge transients without choking
  • May be rack mounted for touring rigs

World class DI

At the heart of the design are two high performance Eclipse ET-DB2 transformers. These deliver 20Hz to 20kHz performance with less than 1.5dB deviation above 18kHz and are able to withstand tremendous signal levels without distortion. Unlike active circuits that overload when the signal exceeds the rail voltage, transformers saturate. This creates a pleasing effect that naturally rounds out the tone, acting like a subtle limiter which is particularly advantageous when interfacing the ProD2 with digital pianos, samplers and drum machines that can produce excessive dynamics. Transformers are particularly adept at eliminating hum and buzz caused by ground loops.
