Greetings, Interesting and involved project indeed. What you are looking for is quite complex - involving a controller, USB interface, SD Card interface, ADC and associated firmware, not to forget the power management circuit - all this put on a small PCB. I think the XLR connectors normally don't have power lines - however some have phantom power lines giving 48V or so with very small amount of current just to power microphones. I am not sure whether that much power is sufficient for the kind of functions you want. That part has to be evaluated. I have good expertise with such complex electronic systems and have done quite a few in the past delivering end to end solutions similar to what you want. Some of them are on my portfolio. Please have a look. However as I said this is quite an involved project and requires time and money to produce something worthwhile. So if you are open to the kind of budget and time line I have bid, please get in touch to discuss further details. T & R Alok Pugalia
