Mackie Big Knob Studio+ 4×3 Studio Monitor Controller

Professional 4 x 3 Monitor Controller with 2 x 4 Interface



12-Month Special Financing**



The Mackie Big Knob Studio+ is a complete recording and mixing solution with two Onyx preamps, 24-bit/192kHz USB 2.0 interface, and 4×3 stereo source/monitor pair selection

When DAW interface makers realized in their mad race for power and glory, that they had forgotten about the console master section, leaving no means for artist communication or referencing mixes on different monitors, devices such as Mackie’s Big Knob were created. Of course, that meant a clutter of devices on your desktop, rather than a convenient, compact, seamless all-in-one system—that is until the Mackie Big Knob Studio+. Combining high-quality, 24-bit/192kHz recording over USB 2.0 with the pristine performance of Mackie’s best-selling monitor controller, the Big Knob Studio gives you a complete recording and mixing solution that easily fits on your desktop.

INSIDE THE BOX—Mackie Big Knob Studio 

With dual, high-fidelity, high-headroom Onyx preamps with 60dB gain, zero-latency monitoring, and built-in talkback mic, you can track in a professional setting. When mix time comes, the Big Knob Studio lets you select from different sources, including USB playback from your DAW, and switch between two sets of studio monitors. It also has two headphone outputs with individual level control, independent gain all I/O for balanced listening levels, and even a front-panel input for your Smartphone—Just add powered monitors and you’re good to go.     

USB input/output jack 

The built-in USB interface sends input signals directly to the computer, which can also be routed directly to the monitor and headphones outputs. Similarly, stereo playback and/or the 2-track outputs are always routed back into the device for monitoring and overdubbing (unless you choose to mute them in software). Since the phones and monitor outputs have separate volume controls, you can monitor in any combination. And because analog input signals may be blended in with playback signals for monitoring purposes, overdubs can occur in real-time without annoying and performance-killing computer latency.
