User manual GRASS VALLEY 8916 DATASHEET

[. . . ] [. . . ] 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. 8900V-R J1 J2 AES/EBU Outputs J3 J4 J5 J6 AES/EBU Outputs Delay From Frame Sync J7 J8 J9 J10 AES/EBU Input Loopthru Ancillary Data AES 1 Loopthrough Fixed Delay Controls Variable Delay (from frame sync RS-232 data) Controller LEDs AES RX Processor Delay AES TX AES/EBU Remote Specifications Supported Frame Types GeckoFlex with 8900V-R GeckoFlex Video rear module, Gecko video frames: 8900TX-V, 8900TF-V, 8900TFN-V Ordering Information Performance Sample rates: 32 kHz, 44. 1 kHz, 48 kHz Delayed outputs: ·Minimum:3ms@32kHz, 2ms@44. 1and 48 kHz ·Maximum:510ms Delay increments: 2 ms Operating temperature: 0° to 45°C Humidity range: 0% to 90% non-condensing This module can be mounted in a GeckoFlex frame when ordered with the 8900V-R GeckoFlex Video rear module.
