I don't know if this is correct. The main LED for output remains green. In the background & staggered off to the side is where a red LED can be seen. You can't really see the entire red LED. It's hard to explain what it looks like. Kind of like a crescent moon. In order to keep this red LED from appearing in the background the rig volume has to be turned way down. The manual says that the LED will change colors from Green, Yellow, & Red. Is the manual referring to the large Green LED or the crescent moon shaped LED's in the back ground. Would like to get clarification on this to be certain my input & output levels are set correctly.
Your volumes and output levels are just fine as long as you are not getting audible clipping.
