J7 RLINE_IN1 Analogue signal
J12 LLINE_IN1 Analogue signal
J14 RLINE_IN2 Analogue signal
J22 LLINE_IN2 Analogue signal
J26 RLINE_IN3 Analogue signal
J45 LLINE_IN3 Analogue signal
J9 MIC_IN1 Analogue signal (MIC Input)
J16 MIC_IN2 Analogue signal (MIC Input)
J30 MIC_IN3 Analogue signal (MIC Input)
Analogue signals applied to these connectors are AC coupled before
being input to the WM8973.
Table 3 Analogue Inputs
Note: When used in Master Mode, an SPDIF signal must still be applied to phono connector
J19. This input signal is used to allow correct operation of the CS8427 as well as being used
to generate the MCLK for the WM8973.
