Detail 01
Passive
No phantom power or battery needed. Transformer does the work, so it survives hot line levels without clipping a front end.

Radial EngineeringProD2 Passive Stereo Direct Box
1/5
Independent shopping perspective
The Korena take
Passive stereo DI for taking line-level keyboard, laptop or module outputs to two balanced mic inputs. For players and engineers with unbalanced stereo sources.
Strong match
Who this is for
- Keyboard rig feeding a stage snake with two balanced runs
- Laptop or backing-track playback into a live console
- Drum module or sampler output to front-of-house
Consider the trade-offs
When to look elsewhere
- Passive guitar or bass pickups needing a high-impedance active DI
- Mono-only sources, where a single-channel box costs less
- Anyone needing phantom-powered gain or a built-in preamp
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Stereo, two channels
Handles a left/right pair in one box instead of two mono DIs, and keeps both channels matched.
Detail 03
Direct box
Converts unbalanced high-impedance signal to balanced low-impedance, so long XLR cable runs stay quiet.
Detail 04
Radial Engineering build
Steel enclosure and book-style chassis meant to be stepped on and thrown in a road case repeatedly.
Final check
Know before you order
- 01No cables included — budget for two XLR runs and instrument or TRS leads
- 02Passive design suits line-level sources better than weak passive pickups
- 03Two channels means two console inputs, not one stereo channel
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does the ProD2 need phantom power?
No. It is fully passive, so it works without phantom power or batteries. Phantom on the console will not damage it.
02Can I use this for guitar?
It works, but a passive stereo box is aimed at line-level stereo sources like keyboards and playback rigs. An active DI suits passive guitar pickups better.
03Is it one box for both channels?
Yes. Both left and right run through the single ProD2 chassis, each with its own XLR output.
04Will it work with a laptop headphone output?
Yes, with the right adapter cable to reach the inputs. It takes the unbalanced stereo output and balances it for the console.
