The PRO-SP17PKIT Prompter People stage pro auto-stepper is a pair of remotely operated robotic columns allowing the prompter operator to adjust the height of the reading glass without going on stage between speakers. Great for conferences, stage and speech events where you have multiple speakers of varying heights. With this option the viewing position can be optimized for each speaker and the glasses can be lowered when they are not being used by speakers. Includes hard flight/travel case.
