The RS6 universal power supply works with the Rane SL2, SL3, and SL4 (not the SL1*). The supply includes different input plugs for the USA, Europe, UK and Australia. The USA plug is attached at the factory. To remove a plug, push the button while turning the outer rim counterclockwise. To attach a plug, rotate it to fit into the supply and turn clockwise until it locks in place. This power supply is regulated 7.5 volts DC, 1 amp, using a P6 type barrel plug.
*This supply does not work with the SL1 (use Radio Shack model 273-1770 or 273-1768 with Adaptaplug N).
