You can adjust the latency of the input audio by using the Delay parameter on the V-80HD. If there is a timing discrepancy between the video and audio, you can correct the output timing by delaying the audio input.

Follow the steps below:

1. [MENU] button -> “Audio Input” -> “Audio In 1”– “Video Player/SRT In” and select “Delay”, and press the [VALUE] knob.
   

2. Use the [VALUE] knob to adjust the latency (delay time) of the input audio, and press the [VALUE] knob.
   Value: 0.0–500.0msec (0.0–11.9/12.0/12.5/14.9/15.0/25.0/29.9/30.0 frame)

3. Press the [MENU] button to quit the menu.
