Transformers


 Hi all,  Has anyone used small  inline balun tranformers? Similar to this.

I have only used inline balun transformers for RF work, not for audio work.   I assume you are converting XLR balanced to RCA single ended?   Since the impedances are high, it should work okay without too much hassle and, for 6$, why not find out for yourself?     
Thank you. XLR to RCA is correct. I didn't know these are directional. These are $43 to $46 each.
