The AirTools 6100 is a 24-bit digital delay unit for live broadcast that prevents unwanted profanity or comments from reaching the airwaves. Engineered by Symetrix, it offers advanced delay technology with up to 40 seconds of user definable delay at a full 20 kHz range of stereo bandwidth, digitally stretching the broadcast audio so that when unwanted comments are dumped from the air, the programming continues on, uninterrupted and without a gap, with no unwanted pitch shifting.
When the show begins, just press START to begin digitally time-stretching the program, creating the specified reaction window of up to 40 seconds of delay time. Then simply push a button on the unit or a remote control panel to edit unwanted or offensive content. Select the splicing algorithm for music or spoken-word programming.
The AirTools 6100 boasts advanced features including digital audio I/O, TC89 time code integration and RS-232 remote control.
User interface menus specify a constant offset time for the TC89 output to add delay to the studio clock TID (time in delay) display. This feature specifically accounts for uplink/downlink latencies or delays incurred from ISDN lines, codec's, satellite signals, and other interruptions. This time offset is adjustable from 0 to 60 seconds in half-second increments.
In RS-232 delay mode, commands entering the unit on the RS-232 port will be delayed by the amount of current delay and then sent back out the RS-232 port. This feature accommodates migration from contact closure or relay-driven automation systems to serial data based automation systems.
