GeckoFlex 8916 AES/EBU Autotracking Digital Audio Delay Distribution Amplifier

The 8916 delays digital audio to adjust for lip sync errors. Lip sync specifications are usually expressed as +1/-2 video frames of audio leading/lagging video. Because human perception tolerates audio lagging better than audio leading video, the specification is looser for audio lag. The 8916 offers tremendous flexibility with two forms of delay that are summed—a fixed delay of up to 0.5 seconds and a variable delay based on the signal input from one of our video frame synchronizers. Key applications include adjusting for a large fixed lip sync error while continuously adjusting audio delay to match video delay created from a video frame sync.
