Hi Guys,
I've got a few of our band's songs recorded on my M20d ('inputs and main mix' on my SD card), and when I'm sitting at home using them to soundcheck our Nexo gig PA, I notice that, whenever a channel has audio recorded, if there's signal present, there's a realtime spectrum analyser wave jumping around on the screen in behind the settings, when I'm in the deep tweak section of the 6 band EQ setting. This is on my vocal mic channel, as I'm trying to tweak the sound of it. Is this just for display purposes of what realtime frequencies are firing, or is there some tangible/operational way it can be utilised to improve sound?
