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".

  • Excellent DI for the $

    As reviewed by maxed on 10/9/2006

    This DI box rocks! I send both my Taylor 514ce & Godin Flat5X through this to the PA (A/B switch) and it carries my tone crystal clear and full sounding, with no added noise. Very clean & natural sounding, and it's passive - so no batteries or phantom power to worry about. The next best DI to the Radial JDI, which I will buy next to get rid of the A/B switch. Best DI under $100!

  • Blown Away.

    As reviewed by Austin A. on 2/26/2008

    We ran a Fender P-Bass into Line 6 LowDown LD300 Pro Combo Bass Amp to this direct box, and the results were outstanding. I didn't think a direct box would make that big of a different, considering i was taking the direct out to my firewire 410 into pro tools. But when you don't use a direct box, you don't have a line signal, so you have to boost it and it captures the mids inaccurately and it doesn't get any bass boom. This direct box made our bass sound go from litterally crap, to near professional, we're going to try an ernie ball stingray and a nice bass amp, and see what happens.

  • Sounded great; died after less than 20 gigs.

    As reviewed by James Jayko on 5/30/2012

    I bought this to replace my $30 Whirlwind DI; I figured I owed myself an upgrade. I used it for 15-20 gigs; it sounded very good. It just stopped working one day, after I had had it for about six months. Guitar Center would not repair or replace it because I didn't have my receipt (makes you wonder why they ask you for your phone number every time), and Radial said the same thing. I bought a BSS from another retailer, and might try to fix this myself since neither the store or the manufacturer have any interest in fixing the problem.
