Hello Dave!
Hums can come from a variety of sources.
Bad cables, unshielded cables, ground loops, gain too high somewhere in the chain, a piece of gear in the chain..... and more....
It can also cone from the soundcard you are using. If you are using a laptop, are you also using the factory sound card? The possibility exists that the internal sound card is at fault. In the years I have been using MC and other cake products, a factory sound card can easily cause all sorts of havoc in the sound and signal dept.
First thing would be to try to monitor the signal at the point it's going into the computer or sound card. Use a good clean stereo amp with some good headphones and see if the hum is there at that point.
If so, you have to work backward one step at a time. If there is no hum..... monitor the output of the computer's sound card with nothing plugged in. Turn up the gain levels and see if hum or hiss comes in.
On a good system, increasing the levels with no input should be silent with no hum and no hiss to talk about....
If you connect the input and now you have hum..... it is either the ground loop OR the sound card. If it's a laptop, while it's connected and running and humming..... unplug the laptop AC adapter and let it run on battery. Is it quiet? If so it's a ground loop. If not..... the sound card is the problem.
So on the sound card... what driver mode are you using? MME works well with many factory cards.
If you are doing this every week..... I would suggest letting the church purchase a decent sound card like M-Audio which uses the better ASIO drivers.
Hope this gives you a starting point in finding the hum.
