Description from Sweetwater :

"The Radial J48 Stereo is the professional active direct box you can rely on whether you're touring stages or laying down tracks for your next EP. Using the same signal path that secured the original J48's place on concert equipment riders the world-over, the J48 Stereo gives you two channels of input, two channels, of output, and sound-shaping-at-the-source control. At Sweetwater we see it as a great choice for keyboard, guitar, and bass players who need the I/O for stereo amp rigs or using multiple instruments. Rugged steel construction on the outside and Radial's award-winning engineering on the inside means your J48 Stereo will be there for you for many gigs to come."
