Normal for DJM 900 to get hot?

@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.

Even if the mixer is sitting in a roadcase with foam up against the sides it will get warm but operate normally.  If you are in an especially hot environment (the ambient temperature is over 25C / 75F), you should take it out of the case during use.

if you have your gear in a road case you can cut out a large square under the unit... just from the middle, with a little vent toward the back.

This way the unit is still sitting up on foam, but the air can pass underneath and vent out the back. make sure all the feet of the unit are still on the foam.

Bonus is you can hide some cables under there too! lol.

LOL.   A large square hole in a road case?

And when you transport the units to another venue, cover the hole with what?  paper?  Why buy a road case if that is the case?  LOL.

Oh sorry.  I totally misunderstood the merit of your suggestion. 

Duh! cut the foam padding under the unit not the case!

The soft foam in most DJ coffins under the units are usually too soft and they trap the heat. Tou only need a strip of about 600mm wide down either side for the units to sit on top of.

If you cut a strip out of the middle the players will not get to about 50 degrees underneath.. and then there will be much less heat buildup inside the players and mixer.

.... i have to speak chinese so often i have forgotten how to speak english properly haha

I like the idea of cutting the foam under the mixer. Thanks!

Attached is an image of a pair of CDJ's that got too hot.. (from Stanton Warriors)

I actually had an older laptop cooler with dual usb fans I never use, i ripped the fans out and drilled 2 small holes under my mixer and installed the fans to keep the 900 cool, works great, attached a pic

Okay so I got myself a Nexus setup a month ago and damn my DJM900 gets hot underneath! I leave sufficient space for air to move underneath and around the sides and back but when I pack up after my gig it is so hot underneath... And the club is well ventelated so it is not even so hot in the dj booth

Came here and I guess I have an answer. Just purchased a DJM900Nx2 and this thing gets extremely hot on the bottom plate and starts to smell like the electronics are cooking after limited use. After about two hours the heat starts seeping to the top plate and is pretty warm to the touch. My studio is about 72 degrees Fahrenheit and I typically use a fan blowing on me and equipment for comfort, so you can see my concern.

I haven't bought a road case for it yet, but I did build a 1" riser out of metal mesh for the decks and mixer to sit on so there's sufficient air flow. 

This is my first Pioneer mixer and with years of experience with other mixers I've never had one behave this way. Everything sounds fine now, just very concerned when I take this thing into the desert if I end up with third degree burns lol. Is this really normal?

Plenty of DJMs run hot, nobody's ever reported one catching fire or burning the DJ. ;)

Knotice, 

I also worried at the beginning when I got my DJM900Nxs1. (you can see I posted about it here back in 2015.)

I later in 2015 got myself an Odyssey coffin where I keep my players and mixer permanently mounted in, with close to zero ventilation in there.
I was always stressing about the heat.

Then one day (I think in 2017) I played at a small outdoor festival where they used my decks, music started at 10:00 and only stopped around 19:00.
It was a very hot summers day here in sunny South Africa.
The stage only had two beach umbrellas for the DJ, which barely gave any shade onto the dj table. As a last minute fix I tried to make some sort of sun-shields with cardboard boxes, so the DJ's could at-least see what's happening on the CDJ screens. It worked a little bit, but the rest of the CDJ's and the complete mixer etc. was in direct sunlight. 

That day the mixer and even the cdj's got VERY hot. but it did not "skip one beat" for the day and played without any issues. 4 years later and they are still going strong without any issues and since that day I don't worry about the heat at all any more. And (except for 2020) it gets used on a weekly basis and often in quite warm night clubs with not much ventilation on the DJ gear (always mounted in the Odyssey coffin). 


I know it is not a good idea to use DJ equipment for a day in direct sunlight and if done often it could very much lead to broken equipment, but I decided to push their limits for the day, so I can then stop worrying about how hot the gear gets. 

Edit: As Pulse mentioned earlier in this thread, it is still a good idea to remove DJ gear from flight cases if it will be used in hot environments.
