User manual GRASS VALLEY 8920ADT DATASHEET

[. . . ] [. . . ] It provides conversion of analog audio to digital audio with the capability to simultaneously adjust for lip sync errors. It offers two forms of delay that are summed--a fixed delay of up to 1. 365 seconds and a variable delay based on a signal from one of our video frame synchronizers, enabling you to adjust for a large, fixed lip sync error while continuously adjusting audio delay to match the video delay created by the frame sync. The 8920ADT also provides various modes of controlling the output audio signal such as channel swapping, channel summing, and phase inversion. 8900V-R J1 J2 Left Analog Input Delay Control Input Delay Control Output Reference Input J3 J4 Right Analog Input 8900CTB-04 connects here for balanced AES/EBU analog inputs J5 J6 J7 J8 Outputs J9 J10 Reference Input Loopthru 8900CTB-02 connects here for 110 output + + Loopthrough Reference Input RS-232 Analog 1 Analog 2 Filter Filter 24-bit Stereo ADC FPGA AES TX Delay Dual 75 Single 110 AES or Video Controller Delay Control I/F Buffered LEDs 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 Signal/noise ratio: ·>102dB, 20Hzto20kHz ·>105dB"A"weighted THD+noise, 20 Hz to 20 kHz: <0. 005%, 20 Hz to 20 kHz, +24 dBu Interchannel crosstalk: <­95 dB, 20 Hz to 20 kHz Frequency response: ±0. 05 dB relative to 1 kHz, 20 Hz to 20 kHz Delay: Maximum: 1365 ms 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.
