Hi Blinky thanks, yes I have a set of 500w skylab pa speakers, I will take some pics of the back of these hopefully today, never seen XLR plugs before lolHiya. I have a limited experience of PA kit but XLR sounds right to me too (for audio input). Do you have proper PA speakers to test them with? Pretty sure normal domestic hifi speakers wont like the power output of those amps, plus the impedance will probably be wrong too.
Ok so I’m thinking rca to xlr female to hook them to a player of some kindYup. XLR plugs are balanced so more suitable for higher power amps, mics etc
