I am trying to install a Yamaha QL1 digital mixer into a pre-existing recording setup, but to make the process as painless as possible, I am making entirely new XLR cables to interface with the microphones, which are currently plugged in to a different mixer via a female XLR that is hard wired into the mixer.
Upon taking an XLR cable to the work site and plugging it in as an intermediate between the existing female XLR and the microphone, I was not getting any sound. I made a second cable, and was extra careful to be sure my connections were correct (it is very hard to screw up with so few wires), tested and got the same results. I began to be worried that the gauge of my wires was too much (not sure if this is actually possible), so I made another XLR cable with smaller wires and once again, got the same results.
I am working with some Wirepath 16-2 PL Speaker Wire that is not shielded. As I have no shielding to work with, the wires are ungrounded, which while bad practice, from my research, is not a killer... unless it is?
So, my question for all you experts here, is does the grounding actually matter, as in, will the XLR cable just straight up not work without some grounding on that first pin? If not, what else could be causing my XLR cables to not carry sound and power mics?
