If you mean my review, that feature was off when I tested it.
Thats nice to know, if you don't mind I have a question for you, at the time of measurement have you experienced an high pitched noise coming from the unit itself? (not in the signal).
I ask this because when I cold start my unit after being unplugged for a while, it starts making this high pitched noise inside (barely noticeable), until I restart the unit then it stops forever unless I unplug the main power again.
I don't know what is causing that, I also don't know if it's something related to other units or just mine, but if is related to other units than is it possible for it to be potentially the core of the problem shown in the measurements?
