Vgard82:
I guess the rack units have more processing power and better converters than the Pitch Factor?
This is no doubt true, but the PF is neither low powered nor equipped with bad converters. While we might have a financial interest in persuading everyone to buy rack units, I'm not sure that this would be the solution to your situation unless your requirements are very demanding. There is a whole world of issues involving bad cables, impedance mismatches, incorrect gain staging etc which are more likely to be the cause of your problem.
Unfortunately, it is obviously hard for us to diagnose these problems remotely. It's very helpful when other users have similar setups and have solved the same problems.
