@Edward Valencia > All electronics usually get hot when used a lot, plugged in charging, or doing work like computers. Same goes for the DJM mixers, so yes this is normal. :)
Just make sure you leave half an inch on each side of the mixer for air flow, and don't cover up the back with something that could restrict it's access to clean air. If you use a coffin case, you should invest in one with built in fans to ensure your gear is properly ventilated.
