I bought my mixer about 4 months ago used from a local supply store and noticing that the mixer itself starts to get pretty warm after about 40 mins of use.
There is plenty of room around the mixer to allow for airflow as it sits on top of a table. This is my first high end mixer purchase so I’m not sure if this is normal.
Mine gets pretty damn hot. I had a burned out PSU PCB a year ago that was replaced and it’s still running really hot. I’ve taken to not using it in Summer pretty much, and not leaving on for more than a few hours at a time, and taking a small desktop fan to gigs to face onto it
Inquiring with A&H and the authorised service center I took to last year for PSU PCB replacement. Have to open mine up now it’s been a year since repair to see if the same issue has occurred again with the new PSU PCB. Hopefully more than 12 months warranty, at least in Australia.
Por serio tho. Ambient temperature plays a large role in circuit temperature. Even though you have a fan on it and it is well ventilated, you still need to take into effect the ambient temp of the room or space which the mixer resides in.
That being said, it is pretty normal for most audio equipment to get pretty warm. There is a lot going on under the hood. If it makes you feel better, the average auto PCM (in engine bay) will have operating temps in the 160-180 F range and they last decades. Dont stress about your audio gear getting hot. As long as that faceplate isn’t hot to the touch, you should be good to go.
