Apollo S90 Audio and Video Are Not Synchronized

1. Turn off or mute the internal speakers of your TV. Refer to your TV’s user guide for instructions.

2. Adjust the AV Sync (Audio Delay) settings:

• Video image processing can sometimes take longer than audio processing, causing a delay known as "audio-video sync issue."
• The Audio Delay feature compensates for this delay.
• You can adjust the audio delay within a range from AV00 to AV200, depending on your TV’s delay requirements. By default, the audio delay is set to 00.

If you have already completed the troubleshooting steps above, performing this reset may restore functionality; however, if the issue persists, please contact us at support@ultimea.com for prompt assistance.
