Four channel analog L-ch input pin. Incorporates an analog selector. And an input switching is
selected by Command AIS (command: 42h) (MIX is also possible). The selected signal is
outputted from OUTL (55 pin).
Four channel analog R-ch input pin. Incorporates an analog selector. And an input switching is
selected by Command AIS (command: 42h) (MIX is also possible). The selected signal is
outputted from OUTR (59 pin).
