I want to use an API-type ACA (active cobnining amp) like classic API's ACA-bo in a box with a few preamps, but also connected to a pair of DB25's for more inputs. I read on ESP's site that because inverting summing amplifies noise more than the signal, it is best to disconnect unused channels. I'm wondering how much noise 16 channels' input R's would induce (assuming 47K input R and 28K feedback R).
Sorry to be asking this when I could just set it up and test, but I really don't want to wire up the DB25's only to find they are unusably noisy without some sort of way to switch them out.
Speaking of switching them out, I figure I could use a toggle switch for each stereo pair, so 8 total, anyone have a better idea?
thanks for the help!
