No you dont need a pot, it comes with one. It comes with everything you need but the 12volt power supply. Id just pick up a small 12v switch mode on ebay ment for a notebook or something similar. The power supply can be as crappy as you want since its a passive volume control. The signal never comes into contact with the power supply. The 12v or what ever will just be converted to 5 volts on board and regulated

PS: Looks like it switches inputs too.
