The Telestream ECO8000-REF offers the option to add three 50 MHz Electronic Fast Switch Channels to the ECO8000 ECO Automatic Changeover Units. While the base unit comes standard with three channels pre-installed, this option offers an additional three channels. With this option installed, the user can switch between analog black burst, HD tri-level sync, AES/DARS, and word clock signals.
The Electronic Fast Switch function comes standard with all 50 MHz Electronic Fast Switch Channels. This function significantly improves the changeover switching speed and minimizes disturbance of the reference sync signals when switching between primary and backup inputs. The Electronic Fast Switch channels feature latching relay backups that engage on loss of power to maintain the selected signal path.
This option is factory-installed and must be purchased with the ECO8000 ECO Automatic Changeover Unit.
