Playing around with this as I have a fairly accurate digital multimeter I assume: Output Voltage Setting on top - the selectable setting on P20 Input Voltage Setting in the middle- this should match the voltage measured out of power socket off the wall Output Voltage Setting bottom - the actual …

I would hope PSAudio does this prior to shipping. However given the drops and abuse these see in delivery perhaps user adjustments add value. It would be interesting to know if the algorithms for output would take these calibration adjustments into account then adjust accordingly. Since few people …

That’s also true whether the culprit ended up being the multimeter itself I think ps would calibrate any units before shipping My p20 is being continuously in use for 3y. Not that should make a difference. Or should it?

Yes, they’re calibrated before leaving the shop.

I don’t know which country people are in, but here in the UK it’s probably best to set the desired output voltage to something like 238v.

I’m in HK. So the standard here would be 220-230V. I did try to push to 240V but too much for the p20
