Description

The FOR-A FA 125 is a low cost Time Base Corrector / Frame Synchronizer. The FA125 corrects by up to one full frame the time base error/ phase shift problems that can occur during recording/playback of composite signals when using heterodyne process VTRs.

Features

→ Analog composite video input/output compatible. (Y/C is also supported.)
→ Full frame memory to prevent picture field inversion during processing.
→ 10-bit digital decode / encode to ensure stable signals without bit dropout.
