P75 mk4 Power Supply and Grounding Notes

The P75 mk4 introduces a new ultra-low noise power supply that is
electrically isolated from the input power. It takes the low grade single
voltage DC supply from the AC adaptor and converts it to dual high
voltages required for true professional quality audio reproduction. Power
supply noise is virtually unmeasurable.
The P75 does not have any mains frequency or other low frequency
components in the power supply and so hum problems that plague
conventional phono amplifiers are eliminated.
While the P75 itself does not generate any hum, the tone arm and
interconnect cables may act as antennae and pick up hum. To remove
hum, connect an earth wire from the turntable to a ground point, usually the
preamp/integrated amp ground.
The P75 is not earthed. An earth terminal is provided on the rear panel that
will allow the P75 to be connected to a ground point if required.
