metronome help please

Hi Goners,

I have the chance to purchase a Kalista Reference with the Reference One Farod power supply [non battery like the lesser Electra p.s.]

Is there a toggle switch or button on the unit or inside the power supply that will adjust for USA voltage of 120v vs. the European version that this is at 240V??

Please keep subject to just this question as i need definitive answers{and yes i have tried Metronome with no answers back!]

Regards all,

Azjake
