[QUOTE="Alan Geering, post: 96434, member: 2093"] Re: Monitor Out Whine Isn't the whine just the pwm for the LEDs backlighting the scribble strips? Last year when testing the hearing loop with a portable tester I picked up a huge amount of radiated noise from the front of the x32. This was coming from the scribble strip area. At that time I also had noise on the output of the x32. I adjusted the backlight values and the noise changed. It has been over 9 months since then so I should maybe go back and recheck.
