The JOYO JDI-48 combines a passive reamp box and a phantom-powered active DI into one versatile tool for guitarists, bassists, and recording engineers. It features 6.35mm TRRS and XLR combo inputs, along with low-cut, phase reverse, and stereo mix options for clean, flexible signal routing. Powered by 48V phantom power—no batteries needed—it maintains high dynamic range and natural tone. With ground lift and -15dB attenuation switches, the JDI-48 is ideal for noise-free studio tracking or live reamping setups.
