Tip is positive, ring is negative. Sounds like telco speak.

I bought this thing years back and never plugged it in. It requires
a 12v dc brick for power and though I have several of them around here
I gotta be sure which is positive on the miniplug the tip or the
ring. Maybe you guys could clue me in on this.
