AVMatrix TS3019-4 Wireless Multi-Camera Tally Light System, 4 Lamps

AVMatrix TS3019-4: Wireless Tally for Four-Camera Productions

The AVMatrix TS3019-4 is a wireless multi-camera tally light system pairing one tally box with four wireless lamps. It tells everyone on set, instantly and without cables, which camera is live. For a growing production that has outgrown hand signals, reliable wireless tally is the small upgrade that makes a multi-camera show feel professional.

What a Tally System Does

In a multi-camera production, tally lights signal which camera is currently on the program output so operators hold their shots and talent knows where to look. The TS3019-4 receives tally data from a switcher and relays it wirelessly to lamps mounted on each of four cameras. Because the link is wireless with a range up to about 656 feet (200 meters), cameras can roam a large venue without tally cables, which is exactly what handheld and roving operators need.

Front and Rear Indicators, Broad Compatibility

Each lamp carries both front and rear indicators, so the camera operator behind the lens and the presenter in front both see the live state at a glance. The tally box connects through GPIO (DB25), USB-C, RS-232, and RS-485, giving it broad compatibility with vMix, other production software, and many hardware switchers through their GPI or tally interfaces, including AVMatrix PVS-series switchers. That flexibility lets it drop into most existing rigs.

Power and Portability

The lamps run from USB-C or battery power, so they can be placed on cameras without trailing power cables, and the system ships with the tally box, antenna, USB-C cords, a power adapter, and a carrying case for transport. It is a self-contained kit built to travel between shoots.

Ideal Applications

The TS3019-4 fits multi-camera live production tally, studio and church broadcasts, event and outside-broadcast camera cueing, and vMix or software-switcher tally integration for up to four cameras. Worship media teams, event producers, and small studios choose it to coordinate a four-camera shoot cleanly and wirelessly.
