Hello,
I am attempting to modify a small Yamaha MS101-4 powered studio monitor/powered speaker.
I need to make it run on 12VDC battery power and It currently takes only AC power.
The internal ac/dc power supply puts out +24VDC with ground and also +18,-18 with ground.
I am proficient enough to implement 12VDC DC to 24VDC DC step up and also to find something for the +/- 18VDC BUT....
There is a additional pin that is labeled "DC_PRT" and I don't know what that means.
See photo.
I am hoping someone here can fill me in on this and possible coach me on what to do with that pin.
Also, if someone knows the 2 different series 'molex' style connectors used that would be amazing!
