I bought this ammoon F4 mixer on Amazon, and I need help connecting a dynamic microphone to it. The mic channels have XLR and TRS inputs. The TRS is marked "LINE" and it works only with line signal from amlified source (like player or so). When I connect the microphone, I can't get any output. When I use TRS to XLR cable to connect the mic to the XLR input, it also doesn't work. I also tried every possible combination of connecting positive and negative wires of the mic to the XLR pins, still no output.
So, am I doing something wrong? Or did I get a mix without microphone preamplifier? If so, is there any small preamp in the size of TRS to XLR powered by phantom? (so it won't take much space and don't need another power brick) Thanks.
//edit: It's unbranded dynamic microphone with 1/4 inch jack, it works fine with mic input on my PC, when using a 1/4 inch to 3.5mm adapter.
//edit2: I had some mics with 3.5mm jack that I used few year ago on my PC for skype calls and decided to use them with 3.5 to 1/4" jack adapter. The first is KONIG KN-MIC10 and it works fine with this mix. The second is Trust Starzz and it has the same issue, not working. Maybe the mix works only with some dynamic mics?
