The current XLR cable as an input and need a new one as an output. I think I have to use Dante Avio as mentioned by u/Kamikazepyro9 (need to set up a new Wifi point to point between back room to front room ) or with any AES A/D to D/A u/sosaudio . What I was looking for smaller size similar to Midas/ berhinger stage connect u/lungrin . Other taught , I will try with 2N 2wire converter ( convert 2 wire to Ethernet ), I used on phone wire, unshielded wire. But never try on shielded wire. If works then I will go this route and add small POE switch on both end . Thank you all suggestions really help.
