It can be done but there's no pinout standard. It's a matter of figuring out how to connect a particular type of mic to that transmitter. Documentation to
wire mic brand X to transmitter brand Y isn't always available. Information is more available when the mic company doesn't compete with their own wireless products (for example Countryman and DPA). Some mics need a
resistor or
capacitor to interface correctly. The connectors are tight and the wires are thin, so it takes some good soldering skills.
