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 and DI/DO, when set to DTP mode
the switcher uses the analog audio source connected to the DTP Tx
instead of the IN1804 DI or DI/DO rear panel captive screw input. When
Input 4 is set for XTP mode, analog and auto audio modes are not
available.
