Emu XL-7 & MP-7 User's Group

Heat is a killer with electronics and it seems that the switch mode 
in these command stations is the weak part. I run mine on 110v (in 
the uk with 240v) which drops the internal temperature down alot.
As for leaving it on for exstended periods of time it shouldnt cause 
any damage. Most DSP's (older generation..) will get upto around 60ºC 
and that seems to be within spec. Thats getting too hot to touch for 
more than a second!
Only probelm really is caps drying out in the power supply, but that 
will happen eventually anyway.
I never leave any appliances on anyway, its saves on the bills and 
the whole planets being sucked dry as it is ;o)
