Audio Selections
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.
