The BA-2 seems susceptible to mains noise.

I always have problems with overloading the input of my ADC...

That could be my dodgy layout! I have to really crank it to hear any of that mains him though.

Just out of interest, what do you use the ADC tx for?

 

[gemini86]

Not sure what you mean but I'm talking about my analog to digital converter.

Ah, sorry, I thought you meant the input transformer.  My input transformer on my pre amp is a vintage ADC taken from an old Gates amp.

I kindof figured that was the case. Stupid acronyms ...

"Room eq wizard" is intended for measuring the room you're in, but it is free(google for it) and has procedures for checking and callibrating your soundcard. with a pad on the input/output, I see no reason you couldnt measure the frequency response of a mic pre (or other processor)working around the programs intended use
