Hi Constantin, thank you on your reply, and sorry to hear that Eric is no longer with us!😢, will try to do a couple pf cables on my own to make it work, normally I get the audio from the mainboard of the sound sistem(mixing board), normally I use either XLR ot 1/4” plug, and sometimes, I even get it straigt out of the speaker out, as long as the speakers are self powered of course!
Thank you Rick!, it is a shame that Eric is no longer with us! RIP Eric, thatnks for the advice, will try to make me some cables!
