Hi.
I'm adjusting this Studiomaster mixer to my needs. I would like to adjust input stages, to avoid line signal being reduced to mic level, and then amplified back to line level. In this way I'm hoping to reduce some input noise.
Input stage looks like this:
http://84.255.203.119/mixer/input.jpg
Line input is fed through 27k resistors, which reduce level by some 30dB (acording to simulation I did). Then signal is amplified by some 30dB back to line level. I want to remove 27k resistors, and go with full line level into transistors (for their balanced input and gain adjustment pot). I will not use mic inputs.
What would be the best way to reduce gain of this transistor stage by some 30dB, bringing it down to unity gain?
thnx
