Roland R-88 battery connector
« on: October 15, 2014, 08:47:57 AM »
Out of sheet curiosity (really! At this point I don't intend to spend $2500 or so) I was looking at the Roland-R88 and noticed that it has a connector for an external battery that I can best describe as a kind of 4-pin XLR. According to the diagram on the side of the R-88, pin 1 is "-" and pin 4 is "+", 9-16V, 2A.

Strictly in theory, finding an external Li-ion battery that feeds something within those specs isn't difficult, but are there plugs that convert from the familiar "laptop" style DC connector to this XLR style plug? Without resorting to a soldering iron?

Roland describes it as a "Professional external battery system". To me that suggests it is not a proprietary system?

Curious,

Christine

If you search around "the interwebs" you can find some stuff but with the batteries we all use it's best to build your own or hit up your friendly neighborhood cable maker  ;)

What are these types of connectors called? Looks like a regular size male XLR (on the R-88) with 4 unequally spaced pins.

so... could you build a cable for dvd batteries?  would that run the R-88?

Yes, any battery that provides 9-16 volts

Do the 9v DVD batteries drop voltage when they get low at all?  I'm tempted to buy the next $1500 one on eBay.
