**Please start video at 1:34 And how can I do it too? He is using a hardware EQ to manipulate a 0db signal (i guess?) to demonstrate how the eq works, but it’s without any actual signal so it’s completely representative of the EQ’s capablities. It would be nice to be able to do this myself as I learn about this stuff. Having the visual along with actually turning knobs would be very helpful. Very curious as to how it’s done, or if it’s not a thing and it’s just an edit for show. Thanks Apologies if this isn't the correct place to put this question. Mods, please move wherever it should be.
