Is possible to.connect ULM202 USB receiver direct to Xenyx Usb input to get both mics working in this mixer?
And if so, which channels get the mic signal? 1 and 2?
Unfortunately, you cannot do this with the QX1002USB. It does not have the compatible USB input for the ULM202USB system. The Q1204USB mixer would have the input you're looking for. With this board, the mics would function on channels one and two.
