PerfectCue is a light and sound signaling system. It enables a speaker to send cues to a projectionist for “next”, “back” and “screen blank” using a wireless hand-held actuator. PerfectCue is a versatile event staging tool. It uses high data rate RF protocol that provides fast responses to the wireless actuator. It contains different types of jacks that make easy hard-wire back-up connections with Cat 5, XLR, EBY or twisted pair cable. These provide for simple interface with other wireless control systems or custom devices. Multiple cue lights can be “daisy-chained” on a single cable carrying both data and power yet they may be operated independently on separate communication channels. A built-in keyboard emulator enables PerfectCue to remotely control presentation applications such as PowerPoint via USB.
