1 = Analog input — Configures input EDID with no audio support.
Analog audio from the 5-pole captive screw input is passed to the
5-pole captive screw analog output and embedded into the HDMI
output.)
2 = LPCM-2Ch — Configures input EDID for LPCM-2Ch support.
Passes all digital audio input signals to the HDMI outputs. If
LPCM-2Ch audio is present it is also de-embedded to the 5-pole
captive screw analog output.
3 = Multi-Ch — Configures input EDID for Multi-Ch support. Passes
all digital audio input signals to the HDMI outputs. If LPCM-2Ch
audio is present it is also de-embedded to the 5-pole captive
screw analog output.
4 = LPCM-2Ch Auto (default) — Configures input EDID for LPCM-2Ch
support. Passes all digital audio input signals to the HDMI outputs.
If LPCM-2Ch audio is present it is also de-embedded to the analog
5-pole captive screw output. If no embedded audio is present on
the input the IN1804 passes analog audio from the 5-pole captive
screw input.*
5 = Multi-Ch Auto — Configures input EDID for Multi-Ch support.
Passes all digital audio input signals to the HDMI outputs. If
LPCM-2Ch audio is present it is also de-embedded to the analog
5-pole captive screw output. If no embedded audio is present on
the input, the IN1804 passes analog audio from the 5-pole captive
screw input.
*On Input 4 of the IN1804 DI, when set to DTP mode the scaler uses
the analog audio source connected to the DTP Tx instead of the
IN1804 DI rear panel captive screw input. When Input 4 is set for XTP
mode, analog and auto audio modes are not available.
