ok so I have a couple questions I'd like to ask about this circuit first
is there anywhere I can read up on basic mic preamp theory? I really would like to know how to tap a mic pre circuits say from a mixer and impliment input an output transformers
on to the circuit first let me explain I'm just wanting to get my feet wet here. I have a lot to learn but eventually I want to understand this enough to build my own preamps.
in pic 1 we have everything but the psu ready to go which is cool, but like I said I want to kind of strip everything down and figure out what I'm doing.
pic 2 ok so I've stripped the protection diodes the dc offset loop and the phantom power circuit. I want to run this off of 4 9volts feeding a akg c1000 mic as a test bed
is it safe to say c1 and c2 the 47uf 63v caps can be dropped down now since there is no phantom power to something like 1uf 25v?
later is it as simple as adding a unbalanced to balanced line circuit to the output "pin 6" and ground? to add the +6db something like this?
also is it true that if i add a transformer balanced out vs active balanced out id loose the +6db?
