## Description

Radial Pro-DI Passive DI Box Passive DI box for stage and studio. No power requirement, works without battery or phantom power. Converts high-impedance, unbalanced signals into low-impedance, balanced microphone signals. High-quality custom transformer for clear and linear sound. -15 dB PAD switch for lowering strong input signals. Ground lift switch to avoid hum loops. 6.35mm jack input for instruments such as guitar, bass, keyboard or drum machines. Thru socket for parallel connection to an amplifier. XLR output with balanced, low-impedance microphone signal. Robust steel housing in I-beam design for maximum durability. Jacks and switches protected by bookend design. Non-slip foam underlay for a secure stand on any surface. Double board technology with bolted steel standoffs. The passive DI box all-rounder. The Radial ProDI is a professional passive DI box specially designed to reliably and losslessly transform instrument signals into a balanced microphone signal. It impresses with its easy handling, robust construction and an exceptionally clear sound. Compact solution for clear signals. The Radial ProDI serves as an interface between instrument and mixing console and converts high-impedance, unbalanced signals into low-impedance, balanced microphone signals. This transformation enables interference-free transmission over long cable routes, a key advantage for live setups and recording applications. Thanks to its high-quality, specially designed impedance matching transformer, dynamics and details of the original signal are fully preserved. Robust technology for demanding applications. The ProDI scores with an ultra-stable steel housing in the "I-beam" design, which protects the interior from mechanical stress and thus increases the service life.

Review: La qualità paga - Conosco la qualità Radial perché ho altri loro prodotti ma fino a poco tempo fa non avevo bisogno di una DI e soprattutto con 2 output. Ne ho provata una di altra marca, economica, ma l'ho dovuta restituire subito.. con questa PRO DI ho risolto il problema! Qualità del suono restituito eccezionale, lo valorizza senza colorarlo. Robustezza di un carrarmato. La qualità si paga e con i prodotti Radial Engineering si va a colpo sicuro ad occhi chiusi. Venditore eccezionale: il tutto è arrivato con 1 giorno di anticipo e impacchettato con cura e protezione più che adeguata.
Review: Night and Day difference... - 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.

## 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.

*by D***N on 1 June 2015*

I use it with electric guitar and bass and it does a great job of eliminating the previous hiss and hum that was present on my recordings.It does so while adding more definition and clarity to the notes.On the bass I feel it adds higher frequencies in a pleasant manner.
