Hi all.
I'm wondering, for console channel, how much DC offset is too much? Is few milivolts ok to go without cap?
I've been playing arround with one channel, and got idea to remove some caps between opamp stages. It seems I could just throw them all out, and still stay within few milivolts offset. Am I asking for trouble, or is it ok to kick those cheap suckers out?
Are caps at line inputs absolutely neccesary? Why?
Are they necessarily placed inbetween each opamp stage?
How to determine the need for DC decoupling caps? Is it proper to make prototype without them, then measure offsets, and put caps only if needed?
If I remove all caps between stages, although I shouldn't, how will I know that I did something wrong? :shock: Will it be obviously wrong immediately, or will it only show later in some special situation?
thnx for help
