Question about the MixPre<n>-ii Series devices:
I have recently acquired both a 3 and a 6. I took them out on 2 separate occasions over the last week for test stealth runs. For stealth, my device typically remains in a backpack for the entirety of the show. The pocket it is in is left open to allow for some ventilation, but it doesn't get much air across the unit inside of a bag.
For both devices, after approx 1.5 hour sets, I was alarmed by how warm the device was to the touch. It was not hot enough to the point where chips would start de-soldering, but it was way hotter than I would like to run any electronic device due to the increased wear on the hardware at such temps. For the second show, I came prepared and dropped a sports injury style gel cooling pack in next to the unit which did mitigate the temp issues. Practically though, it will be a real hassle to have to remember to freeze and bring along cooling for any stealth show.
Does anyone else experience warm / hot temps from the device while recording in such scenarios (in my case P48 was on and USB-C was connected to a battery pack providing power to the unit)? If you are, anything you are doing to mitigate? Just letting it run hot and not worrying about it? Should I switch to an L-mount style battery for power and skip the USB-C to help keep temps down? Any thoughts or tips you could provide would be useful / much appreciated!
