Product Description

Noise-free and very affordable! The Radial ProDI Passive Direct Box is a high-quality, passive direct box that employs a proprietary transformer for both impedance conversion and isolation. Linear from 20Hz-18kHz, with low distortion and virtually zero phase distortion makes it perfect for live or studio performances. Because of the transformer isolation, problems such as hum and buzz caused by ground loops are eliminated, making it very easy and hassle-free to use. The Radial ProDI features 1/4" thru/input, -15dB pad, and ground lift protected from damage by a protective front panel. Heavy-duty construction, baked enamel finish, and 600-ohm balanced output. 2-1/2" x 4-1/4".

THE best direct box for the money

Reviewed in the United States on June 29, 2016

Color: Assorted ColorsVerified Purchase

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.

Must have for active EMG pickups

Reviewed in the United States on September 19, 2020

Color: Assorted ColorsVerified Purchase

So I know a lot of people struggle on the decision to purchase a DI box and should it be passive or active.
I can share my experiences in this search for great guitar tone.
I am going to list my equipment:
Guitars:
Ibanez RG8-EMG 808x (neck and bridge)
Tuning: F, A#, D#, G#, C#, F#, A#, D# (9.5/74)
ESP LTD MH-417-(EMG 85-7H: neck, EMG 81-7H: bridge)
Tuning: G#, D#, G#, C#, F#, A#, D# (10/65)

Audio interface:
Focusrite Scarlett 2i4 (1st Gen)

DAW and VSTs:
Cubase 10.5 Pro
Fortin Nameless suite
Mercuriall U530
Internal Cubase VSTs

I decided to pick up the Radial ProDI passive DI box because I have active pickups in both of my guitars and my tone was muddy directly into the instrument input w/ padding turned all the way down. This DI box is a must have. My tone is night and day compared to the Focusrite instrument input w/ internal padding.
I can't recommend this DI box enough.

Night and Day difference...

Reviewed in the United States on October 12, 2015

Color: Assorted ColorsVerified Purchase

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.

Industry Standard

Reviewed in the United States on March 24, 2022

Color: Assorted ColorsVerified Purchase

As a professional musician who's day job is an audio engineer, I use these constantly. I would not buy a different brand, they're worth the money. Silent, reliable, and bulletproof makes this the industry standard. I use this one for my own music, to run my keyboard to house backlines/PA systems. It's always going to ensure a good clean signal with no hum.

Solid sound

I had a problem getting enough sound pushed through a church sound system with my guitar. This solved the problem and at a fair price.

Worth the cost for quality of sound

I notice an absolute difference in sound quality when comparing this to low and midrange price DI. NIGHT and DAY.

Outstanding tone

Reviewed in the United States on May 12, 2014

Color: Assorted ColorsVerified Purchase

I didn't know if it would make a difference or not. I was using the direct box supplied by my church, just a run of the mill cheap DI box. I didn't tell anyone that I changed DI boxes, but as soon as I started using it, I started getting comments about how good my Acoustic sounded. I'm now a believer...;)

Excellent product!

Reviewed in the United Kingdom on July 8, 2019

Color: Assorted ColorsVerified Purchase

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.
