power adapter - negative pin

Post by cuznmatt »

Does it matter which pin on the 9v power adapter is negative/positive?

The one which came with my kit doesn't say which is which and I need to replace it. not sure what to buy. There is no mention within the manual as to the orientation of the pins on the power adapter.

The (almost) universal standard for DC barrel connectors is negative on the outer sleeve and positive on the inner pin. All of our power supplies follow the standard.

The x0xb0x uses a 9V AC adapter. Not DC. so polarity doesn't matter.

Allmost all Roland equipment and pedals have positive on the outer sleeve btw.

cool. i'm struggling to find an australian power adapter with negative on the outer sleeve. in fact i can't. plenty of the reverse but none with it on the outer sleeve.

thanks for clearing that up.
