## Description

ProDITM Passive Direct Box Compact passive direct box for stage and studio Able to handle huge transients without distortion Transformer isolation eliminates noisy ground loops Plug and play easy to use feature set - on stage or in the studio The Radial ProDI is a passive direct box that combines exceptional audio performance with solid dependable construction, making it the ideal general duty direct box for stage and studio. The heart of the ProDI is a custom wound Radial transformer. It features an exceptionally high 140kâ„¦ input impedance to reduce loading while enabling the ProDI to handle extreme signal levels at all frequencies without distortion. This is further improved upon with an internal mu-metal shield to protect against electromagnetic fields that can cause unshielded transformers to distort.

Glass filled nylon connectors and high cycle switches combine with the mil-spec PCB and internal RF filtering to provide durability and noise-free performance. A full bottom no-slip pad provides both mechanical isolation and electrical insulation to further protect against the rigors of professional touring. The ProDI is ideally suited for instruments such as bass guitar, active acoustics, keyboards and just about anything else! When you consider all of the features and the affordable price tag, it is no wonder the Radial ProDI has become one of the most popular direct boxes ever made. The Radial ProDI... Spectacular performance at a price that anyone can afford!

## 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.
