Review: THE best direct box for the money - As the leader of the sound team in my congregation, I found myself regularly fetching replacement direct boxes for the Berhringer and other brand boxes on stage, due to noise or him, insufficient gain or just a dead box. What I noticed over time is that I never had to replace any of the Radial boxes, and in fact the musicians would sometimes ask me specifically for one. So I started stocking up on them and eventually replaced all of the other boxes with Radials. Now I simply don't worry about the boxes at all--they just work and they work well. These boxes are compact and simple, they sound great with no audible noise, and they're solid as a rock. The Pro D2 stereo boxes are just as reliable, and I've purchased a few of those to cover our keyboardists and drum sets with success. We have a couple powered Pro48 boxes that work well, but at some point I hope to have passive direct boxes exclusively, and leave the phantom power for our condenser microphones. These passive boxes are perhaps the most reliable component in all our sound equipment and I highly recommend to all musicians and venues, big or small.
Review: Quality Sound/Great price - Used for worship team at church. The best sound ever at a reasonable price.

## Questions & Answers

**Q: I have a radial pro48 active di. my interface gets too much signal out of it. will prodi send less? my pickups r active**
A: A common rule of thumb is to use an Active DI with a Passive Bass and a Passive DI with an Active Bass.  That allows the passive DI to handle the active bass hotter signal and the active DI to bump up the level from a passive bass.

**Q: Could this di be used to plug my electric drum set into my system?**
A: If your electric drums have a 1/4" output and your "system" has XLR input (just like my drums and mixer do) then the answer is YES.

**Q: Is this box good for electric guitar like fender stratocaster**
A: very good di, but it is a passive box. your guitar needs to send a line level signal into this di. I've connected this di from the output of a guitar amp or effects foot rack.

**Q: is this the one i need for active guitar pickups with a battery? emgs**
A: It should work with both passive and active pickup systems that use batteries.  I use it with both Fishman and L.R. Baggs systems.

### ⭐⭐⭐⭐⭐ Night and Day difference...
*by J***X on October 12, 2015*

You may notice: this DI box only has 4 and 5 star ratings. Its wonderful. I wanted to get the JDI though money was tight and I was using points on my credit card to make the purchase. I went with this because I only needed the basics anyway. I keep this in my utility bag. Many venues already have a DI and I just use what they have. Some smaller places may have basic sound equipment though no extras like DIs or adapters. In a situation like this you may get through the show with no issues though after using this, I realize when going direct into a board DI isn't just convenient: it's a necessity. It makes a world of difference. I played a spot recently and this box saved the performance: we were having issues with sound and once we were able to get signal there was a lot of extra noise. Using the ground lift eliminated the hum and buzzing and kept the guitar signal strong. I actually now prefer putting my guitar and vocals through a pa/mixer because it's less for me to carry to the place and exceptional sound. I would recommend this DI box as a great sounding and problem solving way to go direct in. I think it's the only way to go.
