Reviews and questions about the entry-level MPC500

Hey people,
I got myself an mpc500 at my pawnshop for 250$, so 4 this price there wasn't much with it. And by that I mean no power supply.
So I found the Akai one for 40$ and one in an electronic store for 5$

The MPC500 ask for a 12VDC w/ 500mA

the one at 5buck is 12vdc/400mA,

I have read on the net that most machine got a little 100 on each side you can go without **** this shit up. I just want to be sure since I notice few of you are engineer of any kind. Yup, thanks for the answers, I did search the forum for an answer but heh! havnt found it, so get mad.

Appreciate the help.

Thanks from Montreal

If the machine starts up with the 400ma one you're most likely in good shape.

I'd say look around a little more to see if you can get one that's 100ma to the other side.

12v 500ma is relatively common...no reason to pay $40 for the Akai one!

try to make sure the mA is the same or higher than 500... the mpc will draw the amperage it needs... but if there isn't enough to provide the machine (in the $5 dollar one there is 100mA less than needed) it could cause problems.

the most important thing you need to make sure of is the pin polarity. check the little diagram on the 500 and the plug.. you will see something like [+} ----(0--- {-]

that will tell you if in the hole it's positive or negative.. and if the outer part is negative or positive... you must make sure this is the same on the plug and the mpc. This is the most important part...

Just to add to this - it may help others - the MPC500 uses a 2.5mm centre negative supply. In the UK its rated 12V DC 500ma (or greater).

I spent some time searching the net and couldn't find the info (plug size) so hope this helps someone!
