I just received my 6600M moving from a 6700 and I can't figure out how to get the audio from the rear audio out and not hear it from the front speaker. Next question is there a way to put the display to sleep? I may have to send this back and keep the 6700.
Jeff you can't shut the display off. I would think they will improve a lot of things related to m versions in the next few months. I sent my 6600m back in exchange for a 6600 because of two failures in two weeks and I feel the interface is a little "unfinished".
Implementation of multi-client in the future might help you if they add meters or something to the front panel. At least you will have something of value to lol at :)
