Title: P12 module, How hot ?
Post by: musicmaker on April 29, 2016, 09:25:12 PM
Saw people mentioning that the P12 modules "runs hot" . But how hot is hot ? You cant touch it ? Where is it hot  ? Does it get functional problems when it running hot  or even shutdown ? what do you do to prevent it running hot and using preventive measures how hot is hot ?  Mine will go onto a shelf with about 10cm of space left and right and lot of space font and back . but I will also run it from MIDI and may not have much space above. Running hot is normally not good for electronics and may shorten electronics useful life but what is actually generating that heat ? the SHARC processors ?(It amazing to me DSI could get so many SHARC proccesors and analog stuff in such a small unit). At the point to order the P12, but just wanted to get some idea to check it out when I receive it.

P.S. Have been going back and forth between a  P8, P6 and P12 for so long now and actually still consider an OB6 (module, when its there).  When the P6 came out I felt I must have it, though after very very long reconsideration and closely listening to  demos the P12 feel like it must be  fun to program and experiment with it's wide spectrum of complex sounds. Perhaps other than many, I prefer to dig deeper than instant satisfaction. P12 feels more like future analog than the recreate the sound of legacy products and that is fine. It did not get as much attention from the media than the P6 and OB6. A big plus me is that DSI publishes complete specs of the MIDi implementation. The overall trend seems that other major brands are  back pedaling on this with newer products and implement proprietary protocols and formats for patch messaging and that 's really a shame (e.g. Nord A1/Lead 4, Roland Boutique, Moog Sub37 among others.....)

I would say Warm rather than Hot.

I have never heard of a P12 module overheating.

I know that the 1st thing I saw in my P12 module manual was the "it runs hot" warning and it really concerned me...but after about 6 months I've never had a single heat related problem or found my module got too hot to touch.  Just use common sense, don't place it in a closed box like location and you should be just fine  ;)

The internals (the main board) of the module is exactly the same as the internals of the keyboard and the keyboard has no ventilation at all. It's not air proof by any means but there are no dedicated ventilation holes. While it does get a little warm on the bottom at some places it's just enough that you notice when placing your hand there.


Seeing how the rear of the module offers plenty of ventilation and the power supply is external rather than internal I don't think there is any reason for worries.
