The 6100 Broadcast Audio Delay—the first product offered in Symetrix’s (booth N1610) AirTools™ family—is a 24-bit digital delay unit designed for live broadcast that prevents profanity or unwanted comments from reaching the airwaves.
As the program begins, the 6100 gradually and unobtrusively delays, or "stretches out," the program until up to 20 seconds of full-bandwidth stereo audio is stored in memory. Users prevent offensive material from broadcasting by dumping the 6100's buffer by hitting the Dump Profanity button. The 6100 clears its memory, and the unwanted material never reaches the airwaves. After the Dump Profanity button has been pressed, the 6100 automatically begins to stretch (time expand) the program audio again until the full delay is attained. The 6100 also features automation interface for network broadcasts.
