Connecting a playback device
You can connect turntables, tuners, Blu-ray disc players, network audio players and CD players to this unit.
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.
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.
