Radial USB-Pro 2-channel Active Instrument Direct Box
The Best Way to Get Laptop Audio Into a Sound System! If you've ever tried connecting the headphone jack of a computer directly to a sound system, you know that buzz, hum, and interference can completely ruin the experience. With Radial's USB-Pro stereo USB laptop DI, you connect to your Mac or PC via USB (no driver necessary) and get crisp, clear 24-bit/96kHz audio quality. Two balanced XLR outputs let you connect with mixers and PA systems, giving you noise-free sound even over long cable runs.
