For a physical connection to each input during your live presentation, NewTek offers LiveControl™ with large, back-lit, easy-to-read buttons allowing for easy transition from one source to the next without looking down or using a keyboard or mouse. All camera, picture, video, and network sources can be placed on either the Live or Preview row. Quickly choose your title, picture, or transition using the rotary dials. Use the T-bar to manually transition sources.
