The Audio screens vary depending on the ROI model.
In default mode, the ROI passes up to eight channels of embedded audio from
the HDMI or DVI input to the SDI output, and mutes embedded audio to the
HDMI or DVI output.
NOTE: The ROI-DVI model can receive both DVI and HDMI protocol input, and accepts
audio if it is embedded in an HDMI signal. However, the DVI protocol does not
carry audio, so if the ROI-DVI is receiving DVI input, only analog audio can be
embedded to the output.
Input Select
Use this control to select which input audio to pass to the SDI output.
• HDMI - This selection passes the HDMI incoming audio to the SDI output (up
to 8 channels).
• Analog- This selection passes only the Analog audio input for inclusion into
the SDI audio stream. In this case, you can use the Analog Out Map pulldown
menu to select the specific channel pair you want to carry the signal.
• Analog + HDMI - This selection causes the Analog audio input to replace
one pair of the HDMI audio channels on the SDI output. The analog audio is
inserted on the channels defined by the Analog Out Map pulldown.
• None - No audio is output (mute) on the SDI output.
HDMI Conversion
The Convert Rate button enables the ROI to convert incoming HDMI audio
between 32 kHz to 96 kHz to 48 kHz (the SDI native audio standard). If you don’t
want to convert, choose Pass Through.
