I have ordered 2 of the same mixers in 1 week. Both have issues with the "meter's" buttons. There is some sort of bad connection and they flip back to Eq mixing mode in fat channel (even though the input, output, GR, or Aux button is pressed and lit. for example: it takes 3-5 times of pressing the "input" button to get it to display and keep displaying input levels on the fat channel. I have updated to v. 9194 and like i said. I am on my second mixer in 1 week.
