With a power supply whom's fan is moving in operation, what is the source of the high-pitched hum I hear that DOES NOT exist with a newer, identical replacement PS??
Is it the fan, transformer or capacitors going bad on the "old" PS?
Note, old PS is still in use on their system(I used a new, identical PS to observe audible differances), but I believe immenent failure will occur, so I want to get a handle on this.
Challenge: The i-unit group was not satisfied with the audio quality during remote meetings. They were looking for a portable solution with excellent audio quality for use in their conference room but also at their client’s offices.
