The 8981FS offers unparalleled functionality.
It combines the best features of a frame
synchronizer, frame delay, and digital
processing amplifier in one module. The
8981FS is designed to handle various
environments and applications including
asynchronous input video signal timing, manual
color correction, and production freeze frame
applications. It operates as a companion to
the popular 8916 AES autotracking delay
DA, and 8920ADT or 8921ADT for audio
synchronization applications. Several control
modes are also offered, including local board
controls, GPI for freeze control, and Ethernet
control over a LAN/WAN using a variety of user
friendly interfaces.
