I want to use a 1:1 audio transformer for galvanic isolation of an audio output. I have some 1:1 transformers left that match my requirements, however they have a center tap on both the primary and secondary. I don't "need" these center taps.
What should I do with these CT pins ? Can I leave these pins unused ? should I connect them to ground (what about the isolation then) ? If I use such a transformer with a CT, will it have an impact from a noise/hum perspective ?
Thank you for your help!
