PerfectCue is a wireless audio and visual cueing system designed for remote control of presentations on one or two computers. It has a reliable communication range of 300 feet between the transmitter and cue light. The system allows a speaker to send cues to a projectionist using a wireless hand-held transmitter or to control presentation software via dual USB ports. Transmitter and receiver relationships are customizable via dipswitch settings, enabling various configurations such as multiple transmitters controlling one cue light or vice versa. PerfectCue also integrates with belt-pack headsets using 4-pin IN-OUT XLR jacks, adding cue light sounds to the audio feed without disrupting two-way communications. It includes audio output for monitoring with volume control.
