I have a couple of AC Infinity fans sitting on top of my Marantz amp, they are plugged into the front USB port. Since I had it, it’s worked great. Amp is on, fans are on. Amp goes off, fans go off.
But now when I turn my amp/everything off (via Harmony remote if it matters) the fans are staying on. I’ve given them 10mins or so to see if they might just take a little while... but they never seem to go off anymore?
I’ve had to unplug them from the front the last couple of nights as I didn’t want them spinning all night. Any ideas why this may be? I haven't changed anything in the setup...
