By: FOR-A
Video and Audio Systems for Broadcast Post-Production, and Professional Video
FOR-A : FA-145
Description
The For-A FA-145 is a powerful time base corrector and frame synchronizer for a variety of closed circuit and broadcast applications. It accepts an analog composite, SD-SDI and outputs a processed composite, SD-SDI signal.
Features
FA-145 features include:
- Supreme composite to/from digital component converter.
- Line synchronizer mode (for minimal delay).
- 10-bit 4:2:2 component system adopted for internal signal processing.
- SD-SDI ANC data signal pass through.
- SD-SDI signal EDH enable/disable.
- Monitoring analog composite output available.
