So, the one thing that is missing here is what is the connector that connects the power brick to the FreePlay? You could take a good quality photo of the FreePlay you have and show us what it expects.

Though often laptops are often 19VDC instead of 20VDC, but given enough current capacity, I'll bet you even money that the 19VDC power supply will probably be good enough.īy the way, you can read the manual yourself here: Mackie FreePlay Manual A lot of the relevant information is on page 15. This sounds an awful lot like a power supply used for a typical laptop computer. All right, so according to the manual for the thing, it uses a 20VDC 3.25A power supply.
