I am mildly versed in electronics. I understand that when you plug a mic into a mic pre the mic expects to "see" or "react" to a specified impedance. I think that you want the mic pre circuit to be x amount higher impedence then the mic (maybe I have that backwards). I also know that sometimes in the "gold ol days" certain high output mics were directly plugged into a compressor and the mic pre was skipped all together. My understanding is that an 1176 or la2a doesn't have the same impedance as a mic pre. I have, many times, used high end mic pres, plugged directly into compressors as well as plugging mics into line inputs on my console with no substantial difference in frequency response or sound in general. So my question is do we really need mic pres. On big tracking sessions most mics need much less then 15db of gain in my experience which any line input, compressor or eq with a gain circuit can handle. So in theory a person could take 8 channels of mic pres, 8 channels of eq (with a line gain circuit) and 8 compressors with a good make up gain circuit and use them for tracking 24 channels of sources. This stretches gear MUCH further saving thousands for people needing 24 channels for tracking. What are others thoughts on this? I've been doing this for years one way or another and have many recordings to back up my claims.
