In the mixer, all the signals come together, are pre-amplified and equalized, processed, mixed, and then sent out again. When it comes to mixers, it's often a case of "more is more."
Based on experience, many users tend to cut costs on their equipment. It's wise to plan with some reserves in mind. So, before making decisions, consider the following:
The requirements for a poetry slam with one or two speakers are different from those for a six-piece band with in-ear monitoring.
If you have only a few required inputs and outputs, a small analogue solution should do the job.
When it comes to handling an entire band or equipping a club for various artists, you'd be better off with a more complex digital solution.
