Hi there, hope everyone is having a great xmas season
I am designing and building a VCA based compressor for a university project.
i have got most of my information for the compression stage and am now looking for circuits for my input gain.
I want a preamplifier circuit that can boost a mic level to a line level and also act as an input gain stage for line level signals to either increase or reduce gain.
I have a few questions;
what are standard gain ranges for preamps? As i understand it I need at least 60dB of gain in order to amplify a mic level signal to a line level signal my logic coming from
~1.2v (line rms) / ~2mv (avg mic) = 600 = 56.6dB
are there any good but not too complex designs out there i could have a look at in order to get my head around the theory . i have designed a basic preamp in TINA pcb simulator but when i attempted a gain of 600 the initial input was quite wonky before it settled out on my simulations, obviously not desireable
any sites pertaining to good circuit design would be good also, i have designs for a lot of the stages (theoretically), but putting these into practice is proving tricky.
thanks for any help given
