Radial ProD2 Passive 2 Channel Direct Box

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!

Expensive compared to other DI's but worth it. Noise level is low. The thing is built like a tank. I feel at ease when I use radials because of their track record.

I grew up on the affordable options. I mean, it's just a DI, right? About 8 years ago, I came across Radial Engineering DI boxes, and I was blown away. I instantly heard the difference in the sound, and appreciated the engineering they put into their products. I find myself EQing a lot less, because the sound comes through rich and clear from the start. Of course, a DI box is designed to take a line level device like a synthesizer and split the signal. One continues the line level for local amp or mixer, the other output is line level so it can go to the main PA. I picked these DI boxes for a really good high school musical. In the orchestra pit, students playing synth were relatively new to the idea. They were piano players, using borrowed synths. So, they didn't know the ideas of gain staging, how to set volume for different patches, or even have an ear to balance their instrument in the pit. (Good players, but these were areas of their craft they were still developing - pretty normal for high school.) Because they didn't understand gain stage, the volume from the synth varied 40dB across the shows. This really tested thes DI's ability to handle such a wide dynamic range, but it did it with flying colors. I always had a clear signal to work with, which I fed to the PA and the recording.

Our church recently remodeled, and replaced our acoustic drums with electric drums. The size of our sanctuary just couldn't handle acoustic very well (too small/loud). The problem was, once we hooked up the electric drums we had an issue where they would periodically "clip" (pop in the speakers) when hit harder. This didn't seem to be a consistent repeatable thing, it just kept happening consistently-random. To avoid this, we had to pull the drum kit volume down to 3 or less (Default is 13). Additionally, there was this TERRIBLE BUZZ in the speakers. NO matter what volume level you put the drum kit on, the buzz was still there (Same level). When we pulled the drum volume down on the mixing board, we could reduce the volume of the buzz, but not eliminate it altogether, and then, all the other instruments/vocals were overpowering the drums. So i did some research and concluded that we must be experiencing a "Ground Loop". After reading reviews on this product, i though i would give it a try. I installed this between the drum kit and the snake. When i powered on the sound system, i was shocked that there was NO SOUND. No buzz, no hum, no noise of any kind. it didn't even sound like i had turned anything on. Our sound system has NEVER been that quiet, even before the remodel. My first thought was "Man, this thing isn't working, now i have NO sound". As i walked toward the box to start trouble shooting, it occurred to me that i should at least TEST the drums first. Guess what, they WORKED. The box was just THAT GOOD. Praise God. Additionally, this also seemed to fix the Popping / Clipping volume issue we had previously as i can now put the drums back on the default volume level of 13 with no issues.

Nice addition to the studio and useful in live situations. Solid, quiet. Will probably purchase another.

If you need a DI box, this is the brand to buy IMO.

Our band has played around 8 shows in smaller clubs within the last year. We use 3 of these mounted in the J Rack (sold separately). These DI's are built like a tank, no hums, no problems. I almost forget we have them because we've never had an issue. I just bought a fourth today as we are going to add a few more outputs to the FOH. In our setup, we have multiple outputs coming from a MOTU 828mk3 rackmount sound card and use these to convert to XLR, remove hum, and protect the audio device from any accidental phantom power from the mixing desk. While everything routes through the sound card (so that's your true source), we essentially have keyboards, guitars, vocals, and our backing tracks all coming through these. Never heard anyone complain about tone. The sound guys at the desk are always happy to see us roll up with our own DI's. Normally they have 1 or 2 if you are lucky at a small club. Note: I don't have experience with any other DI because every review I read said to go with these. I have no reason to look any further.

Used for two main unbalanced outputs to a PA to produce a stereo field live. Voltage drops to microphone level, which really cleans up the sound enabling low impedance transmission. Compared to a much cheaper version, the sound was noticeably better. Worth the money!

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.

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.

Buen producto, de alta calidad 👌

Works great. Very sturdy. A professional product.
