When you’ve got a keyboard that needs to plug into the PA system, make sure it’s clean.

Radial ProD2 is a stereo (2 channel) passive DI box designed to help do that exact thing. If you want to step up to every bell, whistle, and genuine Jensen transformers, you’d best check out the inimitable DUPLEX. Failing that though, this compact version has got the nuts and bolts to ensure your gig cruises along smoothly.

At the heart of the design are two high performance Eclipse ET-DB2 transformers (by Radial). 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.

Features:

  • 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

As with all Radial products, the ProD2 is built tough to handle the rigors of professional touring. A 14-gauge steel ultra rigid i-beam skeleton frame eliminates opportunity from outside stress to flex the sensitive PC board and cause premature solder joint failure. The innovative book-end design creates a protective zone around the connectors and switches further increasing lifespan.
