2 x 2 USB Interface with 2 preamps, Zero-latency Monitoring, and Tracktion 3 Software. Put Mackie quality right into your DAW rig - and right on your desktop! The 2 x 2 Onyx Blackjack interface makes it happen, thanks to two premium Onyx preamps, 24-bit/48kHz quality, a built-in DSP matrix mixer, and DI input capability for instruments. Each of the Onyx Blackjack's two inputs lets you plug in either a mic or an instrument, and both inputs are phantom powered. You can also monitor with zero latency, so you'll feel more comfortable when you're tracking. This handy, desktop-friendly interface runs on your computer's bus power, so you don't have to deal with an extra power supply. The Onyx Blackjack even comes complete with Tracktion 3 music software.
