3-2. Connecting the Phono MM Compatible Input Port to an Audio Device
• You can connect the analog output of the turntable to the phono analog audio input (PHONO IN) of this unit, as shown in the following figure.
• When using the phono audio input as the source, you need to switch the input source to “PHONO” in the input settings. Input settings can be
changed by remote control or manually.
• Although the default switch setting is MM mode (

), please check one more time to see if the mode settings are properly configured.
• In Phono MM mode, the input sensitivity is 5 mV (-43 ㏈u), and the maximum output is 200 W (8 Ω) for stereo / 400 W (8 Ω) for BTL.
• If the input source of this product is set to “PHONO” and the volume is suddenly increased without a turntable connected, a humming noise may
be heard from the speaker.
※ The ground terminal (SIGNAL GND) of this product cannot be used for safety grounding. Connecting this terminal when there is a lot of noise
may reduce the noise. Depending on your turntable, connecting the ground wire may have the opposite effect as it increases noise.
In this case, there is no need to connect the ground wire.
