Whether you're a guitarist, singer-songwriter, electronic musician, producer, or DJ, this studio-quality interface handles everything you can throw at it - just connect your mics, instruments, synths, and MIDI gear, and start creating.

It's fast and easy to use - you control all its features directly from the touch-sensitive front panel, with no extra control software required. And it's built like a tank. You can throw it in your bag without worrying about fragile knobs breaking off. It’s also powered from the USB bus, so you don’t need an external power supply either.

Need to cue a headphone mix? Set input and output levels? Direct monitor your vocals? Just touch the panel and you’re good to go. Plus the same robust iConnectivity MIDI technology that studios and touring acts rely on is built-in, no external dongle needed.

ConnectAUDIO2/4 includes a great software suite for free, with Ableton Live Lite and an inspiring collection of instruments and loops from Big Fish Audio. It’s everything you need - just plug in and make music.
