[BC] Re: [Pubtech] 3 phase power and audio

[Harold Hallikainen]

I had not heard of the preference for keeping all audio loads on the same
phase of three phase power before. I'm guessing this is so leakage
currents to ground are in phase so the chassis voltages on all devices are
in phase, reducing ground loop currents or common mode voltages on analog
inputs? Is that the reason for this preference?
