The Digital Arts TL-2-C Tally Light is compatible with the TLC-4S, TLC-8S, TLC-8d, and TLC-6 Tally Controllers. It features an ultra bright red LED on the front, facing the on-camera talent, along with 3 indicators on the back, facing the camera operator. 

The intercom pass-through connector on the controller is connected to the 1/8″ jack on the TL-2 Tally Light so that your intercom beltpack (with the proper adapter; sold separately) can share the tally cable. This tally light can be mounted on any standard camera accessory shoe with the included mount and can be connected to the controller with a standard Ethernet style cable up to 1,000'.
