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. The delay is applied to all AES
channels prior to embedding.
