YES the fundamentals are just as important be it an analog mixer or digital, as well as understanding signal routing through a mixer.You are right DR! Also…Lotsa bad drivers out there too! You don’t have to be one.
I’m just pointing out that there are a ton of fundamentals to learn like proper mic and speaker placement, gain staging, etc that you should learn to do correctly before cutting up a room eq into a mess chasing feedback.
As a sound tech that worked as a house guy for venues and for bands I can’t count the number of bad room eq jobs that needed fixed in order to mix properly. Yes, I’d put them back to whatever goofy setup I walked in to…
Cloud rant over!
If possible after a system install / upgrade job where they went from an analog mixer to digital sometimes I like having their analog mixer nearby to compare the controls and functions directly between the two when doing training.
