Kill buzz with the Radial JPC, a direct box configured specifically to erase the hum associated with connecting computers to an audio system. Using a combination of active buffers and transformer isolation, the analog JPC is fully stocked with inputs and outputs, like 1/4", 3.5mm, RCA, and even stereo options, making it the perfect interface for unbalanced sources. Just plug it in and hit play for noiseless playback, courtesy of the Radial JPC.
