This IC has a function to auto distinguish HiFi and Normal by the presence or absence of Rch envelope, which can be
turned ON/OFF by using G2D6.
When output Monitor signal to REF OUT at the time of replay, turn off this function and make the following settings.
1) G2D6:1 (Auto detection OFF)
2) G3D3:1 (Select Through Monitor)
