Extended Tallies
The Synergy 1.5, 2 and 2.5 Q/MD system includes 36 configurable tally relays, each of which can be
assigned to any video input or MLE program output. The Extended Tallies option provides an
additional 36 tallies, bringing the total number to 72. These additional tallies are equally configurable
and can be added for red/green preview tally systems that require twice as many tallies, or for cases
where every single input requires a tally.
A preview tally system has a “red” output indicating that a source is on air and a “green” output
indicating that a source has been selected on a preset bus. This gives the talent an additional warning
as to the director’s next move. “Green” tallies require the
Extended Tallies option.
The Extended Tallies option is comprised of hardware relays that are installed in the control panel
tub.
Redundant Power
The Redundant Power Supply option provides protection against the failure of an individual power
supply shutting down the entire frame. In the standard configuration, if the power supply in the
Synergy Q/MD frame fails, the system will shut down immediately. With the Redundant Power option
installed, you gain a second power supply to allow the frame to operate in a N+1 mode. In this mode,
any one of the power supplies can power the entire frame if the second power supply fails.The N+1
mode allows for the hot-swapping of any one power supply without the interruption of the system and
can even be done during live broadcasts.
There are two Power Fail indicator lights, one each for panel and frame, on the main control panel that
will illuminate to show a failure or a problem with a power supply. The status of a frame power supply
can be determined by the position of the individual power supply switch and the illumination of the
green, yellow and red LEDs on each power supply.
Installing the Redundant Power option does not increase the amount of rack space required by the
switcher. The extra power supply mounts in a provided slot inside the frame.
Note that redundant power is also available for the control panel. Contact your Ross Video
representative for details.
Spare Parts Kit
A Spare Parts Kit is available that provides switcher parts according to the following criteria:
• the part comes into frequent contact with the user
• the part can be easily damaged or may wear out with excessive use
• the part can be lost easily
Parts that fall outside of the above criteria are not included.
Note The Synergy 1 Q/MD has a maximum of 16 standard tallies and
cannot be upgraded with the 36 additional tallies option.
