Evertz quart tr3200a ( tr-3200a ) tally router


Quartz routers are often used to route signals to a vision mixer that is feeding a transmission path. In this situation users need to know which sources are on air.

The Quartz TR-3200A Tally Router can provide tally indication to the lights both on the cameras, called reverse tally, and on the monitors, called forward tally.

Traditionally tally routers use a matrix of relays that follow the video router and thus route the tally back to the camera. For a 16x16 router 256 relays would be needed; this is both expensive and large compared to the Quartz solution.

The Quartz Tally Router has input and output interfaces only, and utilises software to process the matrix pattern, instead of a complete matrix of relays.

The TR-3200A has 64 electronic inputs that can sense the tallies from the mixer. It connects to the router by the Quartz Q-Link system to obtain router status. The unit controls 32 output relays to drive tally lamps.

The 64 tally inputs are spread across the four lower D25 connectors with 16 input signals per connector.

The 32 tally outputs are spread across the four upper D25 connectors with 8 output signals per connector. The four output tally connectors may be individually assigned to provide forward or reverse tallies. Two wires are provided for each relay to ensure full electrical isolation.

There are several different types of Tally system covered by this application note: 1) Reverse tally routing, normally camera on-air lamps. 2) Forward tally routing, normally monitor on-air lamps. 3) Red/Green tally routing, normally on-air and ISO or VTR record tally. 4) General tally routing, routing a tally signal from A -to-B. 5) Dummy tally routing, tally routing when the corresponding video is direct to the mixer
