Mic / Mic Bias 

The MIC signal is used for microphone input. This input is fed to the left 

microphone channel. 

Mic Bias provides 3.3V supplied through 3.2K 

Ω with capacitive decoupling to 

GND. This signal may be used for bias of some microphone types. 

Line-In L/R 

Left and right line in signals. 

Line-Out L/R 

Left and right line out signals. Both signals are capacitor coupled and should have 

GND as return.
