Control your whole studio from one big volume knob – and record through it too. The Mackie Big Knob Studio+ is a desktop monitor controller and 2×4 USB recording interface. It switches between up to four sources and three pairs of studio monitors, gives you two Onyx mic preamps for recording, and adds talkback and headphone feeds for working with artists.
Why customers choose it
Who it is for
Project and home studios with more than one pair of speakers, producers who switch between monitors and headphones, podcasters and live broadcast setups, and professional studios that need talkback and a headphone feed for the artist.

FAQ
Can I use it only as a monitor controller, without a computer?
Yes. Source and monitor switching, volume, mono, mute and dim work as a standalone controller; USB adds recording and playback.
Can I record two mics at once?
