Dedicated analog connections for predictable signal flow.
Take a look at back panel of a StudioLive 16.0.2 USB mixer, and you’ll find the robust connections you’d expect from an analog mixer: balanced mic inputs on each of the 8 mono channels; 8 balanced ¼-inch line inputs; 4 unbalanced RCA line inputs; and dedicated balanced outputs for each of the 4 aux buses and the main stereo bus. Every input channel and bus send has its own dedicated jack—no sharing, no compromises—so you always know what’s flowing from each output.
