Comprehensive connectivity for recording and monitoring Theres a lot you can do with the Mackie Big Knob Studio. As an audio interface you can record two channels of high-fidelity, low-noise audio, courtesy of dual Onyx mic preamps. A Direct Monitoring option allows for no-latency recording, and built-in headphone outs are ready for artist monitoring. If youre like Sweetwater recording engineers, you know the importance of reliable studio communication. With built-in talkback functionality, youll be able to communicate easily with your artists. A stereo aux input on the front panel makes it easy for artists to plug in a music player to hear a reference track. And of course, you have complete control over input source and monitor switching. For the cost of a typical USB audio interface, the Mackie Big Knob Studio offers much more.
