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".

5.0 out of 5 stars Must have for active EMG pickups
Reviewed in the United States on September 19, 2020
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.
