For the twisted pair inputs in DTP mode, the analog audio is taken from the
analog audio connector on the DTP Tx.
•
For the TP inputs in XTP mode, the analog and Auto formats are not available.

Sets the selected input to analog.
Sets 2Ch EDID.
If LPCM-2Ch audio is present on the input, it is
passed to DSP for availability on all analog and
digital audio outputs. For 3- or more channel
LPCM (such as Dolby or DTS), the signals
bypass DSP and are re-embedded in the digital
video outputs.
Sets Multi-Ch EDID.
If LPCM-2Ch audio is present on the input, it is

Sets 2Ch EDID.
Defaults to analog audio if digital audio is not
detected on the digital video input, or if no
digital video input signal is present. If digital
audio is detected, LPCM-2Ch signals are
passed to DSP. If 3- or more channel LPCM
is detected the signals bypass DSP and are
re-embedded into the digital video outputs.
