Connecting a turntable
This unit is compatible with turntables equipped with a moving magnet (MM) phono cartridge. When you connect to a turntable with a low output moving
coil (MC) cartridge, use a commercially available MC head amp or a step-up transformer.
If you set this unit’s input source to “Phono” and you accidentally increase the volume without having a turntable connected, you may hear a hum noise
from the speakers.
NOTE
The earth terminal (SIGNAL GND) of this unit is not for safety grounding
purposes. If this terminal is connected when there is a lot of noise, the noise can
be reduced. Note that depending on the turntable, connecting the ground line
may have the reverse effect of increasing noise. In this case, it is not necessary
to connect the ground line.
