Is the blue input light supposed to blink during charging?
Yes, the blue input light will blink when your Yeti is charging. Once it gets to 100% and is topped off the blue light will go solid.
Is there a way to turn off the blinking blue input light on the 1500x front screen, or at least tone down the brightness a bit? In a dark room at home at night while it's charging via AC, that blue light on the front of the unit is incredibly annoyingly bright.
