XLR unbalancing transformer
I'm working on a relatively simple project for a friend to take some XLR inputs and use a transformer to unbalance them gracefully. My normal approach of leaving one of the signal pins floating/grounded is not going to work here, sadly, due to noise/hum problems.
What transformer would you suggest? I'm looking for a "good enough" kind that's not going to cost $40 a pop or something. I know where to get the nice ones but I'm stumped as far as finding 16 just-okay transformers at a decent price.

there's your xfmr.
150 ohms to 150 ohms, so it's just a matching transformer for mic matching impedance.
one side hook up as balanced, the other side just use the (-) side as ground, and voila, unbalanced!
keep mindful about phantom power blocking issues...if that's an issue.

Boom goes the dynamite. I was going to recommend Edcor as well. Mouser does have thousands of transformers but almost none of them are designed to pass 20hz-20khz gracefully.
I like to build the stuff that I record with.
