You can wirelessly jam the TC-1 from your phone via Bluetooth at up to 250' or even sync it from other TC-1 boxes using the company's proprietary 8-channel, 2.4 GHz radio ecosystem. You can also hardwire-jam it or use it to internally generate timecode and jam other devices. An easily readable OLED display provides instant feedback to assure you all the units are in lockstep. This kit comes with three TC-1 boxes.
