I have a question about using the high-z inputs on my board. I currently use a Mackie Onyx 1620 which has 8 mic preamps and then 4, 1/4" stereo channels. Of course I wish I had the slighty larger board with 16 mic preamps because I routinely need more than eight channels, but instead I end up plugging my extra low-impedence cables into a low-z to high-z adapter and then into the mono side of one of the stereo channels. Seems to work, but not that great. Definetly seems like the input volume goes way down when I do that. My question is; am I commiting a big no no? Is there perhaps a better way to do what I'm doing? Any insight would be much appreciated.
