7700 MultiFrame Manual 7720AE4 SD-SDI 4 AES Audio Embedder When set to Disable embedder 1 will be disabled. When it is set to Enable the embedder destination can be set when the DIP switches are set as shown in Table 5-3. Channels 1 and 2 from AES input 1 will be embedded into channels 1 and 2 of the selected group. -
Page 15: Selecting The Audio Delay
7700 MultiFrame Manual 7720AE4 SD-SDI 4 AES Audio Embedder 5.2. SELECTING THE AUDIO DELAY When the DIP switches are as shown in Table 5-6, the toggle switch is used to select one of fifteen delays which can be added to the audio before it is embedded. This delay allows the user to resynchronize the audio back to the video to accommodate video processing delays. -
