Hi I had a quick search and couldn't find the answer.
I'd like to power on my Arcam power amp which has a 3.5mm mono jack with my Sp1.7 to act as a trigger, so my question is does anyone know if I should connect the common from the SP1.7 to the centre pin of the 3.5mm jack or the on/off output from the SP1.7 to the centre pin?
Thanks in advance
