## Description

Radial ProDI Passive DI Box with Radial Transformer

Review: Tough build, good sound. - Does a great job on my active guitar pick ups. Love it.
Review: Utterly brilliant. - Amazing, wonderful DI box. Does as it says on the tim. Perfect in the studio, and when we get to play live again, I know it will be perfect for that too. Happy days. My only niggle, is that the rubber padding under the box moved acid was not secured properly. A minor issue, but doesn’t affect the use of the product in any way. Highly recommended.

## 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.

### ⭐⭐⭐⭐⭐ Excellent product!
*by B***Y on 8 July 2019*

This is a great product. We are using it with a Yamaha keyboard and the sound is very natural indeed. We had been using other DI's but this unit is head and shoulders above. If you're looking for a great DI (albeit a bit more expensive) this is the unit - it's well worth the (extra) money.
