Hi D – for obvious reasons we are limited in the advice we can give to people who are using other manufacturers equipment with which we are unfamilar.
That said, your issue appears to be one of low level and much noise. This is usually caused by incorrect unbalancing. If you connect a balanced (usually XLR) signal to an unbalanced (usually mono jack) signal, you must be sure that all the balanced signals are connected to something.
For example, when connecting an XLR to a mono jack, pins 1 and 3 of the XLR should be connected to the sleeve of the jack, with pin 2 of the XLR connected to the tip.
