Description
Microphone Input. The MIC input may be either line-level or –20 dB from line-level (the
difference being made up through a software controlled 20 dB gain block). The mono MIC
input may be sent to the left and right channel of the ADC for conversion, or gained/
attenuated from +12 dB to –34.5 dB in 1.5 dB steps and then summed with left and right
line OUT before the Master Volume stage.
