Connecting The Power Cord - Sonoro Maestro SO-1010 Operating Manual

NOTICE!
Risk of damage!
The GND terminal of PHONO is not a safety ground connection.
Connect the ground cable of your record player here to reduce hum and noise.
If input source is set to "PHONO" without having a turntable connected, you may
hear a hum noise from the speakers.
Depending on the turntable, connecting the ground terminal may have the
reverse effect of increasing noise. In this case, it is not necessary to connect the
ground terminal.
