_Analog Audio Input Connector
The analog audio interface consists of four (4) mono inputs and one mono output (for talkback). This interface complies with the Intel High Definition Audio (HDA) specification.
The audio input channels support 48-kHz sample rates with 16-bit PCM data.
The audio input channels support up to 4.15Vpp (single ended) inputs. The input signal level is configurable from 2 to 8 dBu, with a default value of 6 dBu. The maximum input level of 8 dBu translates to a maximum value of 5.50Vpp.
