Stereo Profanity Delay
RB-PD2: The Redbox RB-PD2 is a stereo audio profanity delay used for live broadcast programs to prevent unwanted or obscene material from being transmitted. It features both analog and digital I/O and an automatic audio stretch algorithm that allows between two and 55 seconds of delay to be built up live on-air while maintaining the correct pitch. When the program is complete, the audio stretch algorithm seamlessly reduces the delay to zero. The delay can also be acquired while playing a preselected audio file on a Compact Flash memory card, and because playback from a Compact Flash card can be triggered remotely, the RB-PD2 can also be used at transmitter sites to play an emergency audio file via GPI in the event of silence detection.
