dedicated power receptacles for mono blocks?

I forgot to mention that if you had the voltage switch set to 240 volt you would also be plugged into a 240 volt outlet!

Monoblocs on different legs will likely have a ground loop hum. I know!

@noromance has it exactly correct - pick and stick to one leg of the panel when creating n > 1 dedicated home run audio power lines to your panel. IF at all possible in that adventure put all motors and inverters on the opposite leg. I normally start with all the digital stuff on a dedicated line with a Furman or better Power Conditioning… and then move the DAC between that circuit and the all analog leg to hear which is better…often the DAC designed by people who understand the value of a proper Faraday cage AND Galvanic isolation end up living on the better sounding analog side… just my $1.50

I have one dedicated 20 Amp cct for my mono blocks and entire system. No issues

Monoblocks on different legs can result in ground loops UNLESS they have fully differential inputs and  can lift the ground.

Some amps offer XLR connections but only as a convenience. Some Parasound amps come to mind. For this reason it’s worth checking this first.

This should eliminate the possibility of a ground loop, regardless of anything else.

With unbalanced (RCA) connections I’d never attempt this.

Clarification: I meant lift the ground on the XLR input, not on the AC.

I have 2 mono blocks on 2 dedicated outlets. No issues 

It sounds like having the dedicated outlets on the same phase will reduce the possibility of ground loops. 

Thank you responders!

If you can swing it, they recommend getting two twenty amp circuits.  One got your amps and the second one for everything else. I just have only one, but it’s working fine for me.
