Hi there i have a strange problem
i´ll begin with describing what i have built.
I have a ba283card and a 2 bank 23 pos elma switch. i have a fixed gainboost on the second stage a 470 ohms resistor instead of 1,5k.
then attenuate with the first bank of my swith from 4 db to 55 db after that i boost the first stage up to 27 ohms, with the second bank.
I also have a 604 ohms resistors on the output xlr to match my impedence of my computer.
Now when i plug in my guitar i get the right sound but when i try to plug in my synth the gain gets so high that everything gets red i have my volume on my synth almost set to zero , and on the pre amp the switch is at 4 db and the fader pot almost a zero and still i get the sound so high that it´s crazy i wonder what i´ve done wrong.......also o feel that the preamp is poor on bas frequencess it only goes down to 200 hz with the guitar and a microphone not to talk about the synth why why why why why
