Voltage setting for Amp

Hi guys

I am wanting to know what the best setting would be for fixed voltage output on when using XLR? So to match the RS150b to mt McCintosh MA352 Amp

Cheers Barry

Spec for xlr input is 0.5v and also it has power guard that monitor output clipping and auto adjust input levels to prevent output clippings…

Thanks sorry I may need some further explanation :frowning:
