Input Source
Choose which embedded audio channels are routed to the HDMI output. Eight
channels are routed at a time. You can choose Ch 1-8 or Ch 9-16 from any SDI
input.
HDMI Channel Count
Choose Auto, 2 of 8 channels or 8-channels embedded audio. Choosing “Auto”
automatically selects the audio channels based on the attached device’s
capabilities.
The SDI output embedded audio always follows the selected HDMI Output source
selection and is limited to 8 channels max.
Audio Offset In Frames
Permits time shifting the embedded audio in relationship to the video (for
example, to correct for lip sync problems), in 1/16 of a frame increments. Range is
from -0.8125 video frame to +7.0 video frames. The actual time duration of delay
will vary depending on the frame rate of the format being converted.
Default offset value is 0 frame to match the video delay path, resulting in time-
aligned audio on the output. Positive offset delays the audio additional frames
(relative to the video output), negative offset advances the audio relative to the
video output.
