Edirol R4 Power Supply

(1/2) > >>

vanark:
Does anyone have an extra lying around in their gear closet or can point me to one that won't fry my R4?

I have an external battery, but I just want to use it for some transfers.

goodcooker:
I have a Roland adapter that was used for a UA5. It's 9V center pin negative. Not sure if it's the same.

vanark:
I think it is looking for 9V 2A. I wonder if I still have a UA5 adapter too. I will need to look.

Gutbucket:
R4 power input is different from R44.

If I recall correctly, it might use a hirose rather than a coaxial power input.  Not sure, could be something else.  I only used the R4 briefly but I do recall its external powering differed from the more common R44.

[edited to correct]

vanark:
The battery cable I have is the normal reverse polarity tip.
