The NewTek TriCaster TCXD850 Control Surface provides touch control over TriCaster TCXD850 live production and streaming. It is the perfect companion to the TCXD850, with back-lit buttons, twist knobs, T-bar and 3 axis joystick, which are mapped directly to the TriCaster itself, meaning you have a physical connection to system functions and effects. With both portable and fixed installation, it also offers ultimate flexibility.
