Radial Engineering ProD2 Passive Channel Direct Box

I use this with my keyboard setup for regular rehearsals and gigs. So far it is meeting all expectations : a good quality, reliable DI unit which is a slightly higher price than others but (in my opinion) is also comparably superior. As others have said, this thing is built like a tank. I've never had any issues with additional noise or connection problems, which I can only assume is a good thing. Great piece of kit.

I have to say, this DI box is an absolute powerhouse. It's built like a tank and can withstand just about anything you throw at it. Whether it's being jostled around in a gig bag or dropped on the floor, this DI box just keeps on working. What's even better is that everything about this DI box just works. The sound quality is fantastic and it does exactly what it's supposed to do - take an unbalanced, high-impedance signal and convert it to a balanced, low-impedance signal. I've used it for everything from recording to live gigs, and it's always performed flawlessly. But what really sets this DI box apart is its durability. It's probably the best in the industry, and I've seen firsthand just how tough it can be. It's been dropped, and stepped on, but it still keeps on working like a champ. Overall, if you're in need of a DI box that's incredibly durable and reliable, this is definitely the one to go for. It's built to last, sounds great, and just does what it's supposed to do. Highly recommended!

Very good product. No noise added. Sound quality is good. XLR output is just transformer's secondary winding so should not connect to mic in port that gives phantom power. In PC mic out, it gives 3V phantom power for microphone. When connected to XLR, it was like short circuit and voltage was dropping and caused click sounds. Added two nonpolar electrolytic capacitors in the circuit to block voltage and pass signal, now working correctly.

This is a stellar DI box and is rock solid. We have other Radial ProDI's that have been used heavily for 10+ years and still work as well as the day they were new.

Works great. Very sturdy. A professional product.
