The ‘Input Pairs’ field shows the possible audio inputs available and the ‘status’ of these audio inputs.
Note: the analog audio inputs will always report ‘PCM’ regardless of whether or not audio is present. Any analog input will be converted via an
ADC to PCM and then processed as PCM. Hence the ‘Status’ of the Analog source will indicate ‘PCM’.
Note: Dolby Encoder inputs are routed from the Dolby Decoder outputs. If the particular video channel can support the Dolby option, but the
option is not installed, the Dolby ‘sources’ and ‘status’ will be grayed out. If a particular video channel cannot support Dolby (LC/SV2000
Channel 2, LC/SV4000 Channels 2 & 4) then the Dolby sources will simply not appear
