Best reviews of ???? Radial Engineering Radial Engineering ProD2 Passive Stereo Direct Box ????

A high-quality, passive direct box that uses 2 proprietary custom-made transformers, one for each channel, 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. Features include 1/4″ thru/input, -15dB pad, and ground lift protected from damage by a protective front panel. Heavy-duty construction, baked enamel finish, and 600ohm balanced output. 3″ x 5″.
