mpc internal voltage consumption

Hello chaps,
does anyone know the internal voltage requirements of the 1000? That is, post the 240/110v AC transformer. I'm about to take it apart and will post my findings but if anyone has done this it would save me some time. I'm running the mpc on a 12v DC supply inverted to 240vAC which seems a bit long winded and wasteful.

i have no idea, but i'd be interested to hear about your findings...

cheers.

speaking of this brings up a question from me:

i have an mpc i bought here n usa. i see no control on the back to adjust 110 to 220, so in the event i want to use it in europe. does the mpscregulate/convert the power automatically (like my laptop), so that i i only need to use a plug converter, or would i need a full step down type of converter to make sure it doesn't get fried?

thanks a million for the link. Just ran a meter on it myself- there's a 240v AC input module which then goes to a module that outputs the 12v, -12, ground, ground, 5v,5v.
(my readings were 12.44, -12.55,0,0,4.99, 4.99)


Next step is to try with a bench supply and observe current requirements and then build a 12vDC in (from car battery) to 12 and 5 out- and then see if there's any noticable improvement on battery drain.

cheers

I´m no expert at this but i´m really curious, so please go on, try and keep us updated..

the 5v is for the USB port I would imagine

what is your goal with this? I see your from the UK, is this simply because of the difference in wall outlets over there or is your goal to make some kind of battery pack?

*crosses fingers*

pleeease say battery pack...


though it'd probably be too heavy to be practical...

are you doing this for in-car use or something?

i bought my mpc from usa and i'm using it in europe without problems. no voltage converter needed.

+/-12V will be for the analogue audio gubbins
5V will be for CPU and logic circuits.

thank you zen guru!

actually u should look at the back of the unit if there's something like "100 - 240 V". then u can be sure there's no problem.

the mpc is controlling a midi-relay system that triggers solenoids or dc electrical rams which hit a rack of bottles. It also controls a set of air relays which blow air over bottles- all with different amounts of liquid in to give a range of tones. there's also samples coming off the mpc. The system is mounted on a vehicle- we've been using 12v car batteries into an inverter but the battery drain is slightly limiting. The idea is to cut out the middle man and supply the mpc directly with 12v and stepped down 5v.

that sounds amazing!

do you have any video or audio? or even just pictures on a website?
