Audio format
The audio input format specifies whether the audio input is analog, digital, or not to be sent
to the output.
NOTE: Multi-channel audio does not include microphone inputs or audio processing
when it is sent to the output. It is also unaffected by volume control and does not show
meter activity.
For inputs 1 and 2, available formats include:
• None — Audio is not sent to the output. This option sets “No Audio” EDID.
• Analog — Analog audio is sent to the output. This options sets “No Audio” EDID.
For all other inputs, available formats include:
• None — Audio is not sent to the output. This option sets “No Audio” EDID.
• Analog — Analog audio from the corresponding analog input is sent to the output. This
options sets “No Audio” EDID.
• LPCM-2Ch — The digital input is configured to receive 2-channel LPCM audio. This
option sets 2Ch audio EDID.
• Multi-Ch — The digital input is configured to receive multi-channel audio. If
multi-channel audio is not available, 2-channel LPCM audio is passed to the digital
outputs. This option sets Multi-Ch audio EDID.
• LPCM-2Ch Auto — The digital input is configured to receive 2-channel LPCM audio. If
2-channel LPCM audio is not detected, the input switches to the corresponding analog
input to send to the output. This option sets 2Ch audio EDID.
• Multi-Ch Auto — The digital input is configured to receive multi-channel audio, but
will pass 2-channel LPCM if multi-channel audio is not available. If neither multi-channel
audio nor 2-channel LPCM audio is detected, the input switches to the corresponding
analog input to send to the output. This option sets Multi-Ch audio EDID.
