Honest thoughts on the PRO DI Direct Box
The Whole Family
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".

Regardless, I bought this product so I could mess around with guitar pedals in my recordings while still preserving the DI, and It's doing the job. I wish I hadn't bought a ground loop eliminator prior to this, because this device would have solved that problem from the getgo.
Anybody want a ground loop eliminator? xD
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.
