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, digitially 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.

The 6000's Automation Control Interface offers the ability to trigger automation changes or control a router with ‘delayed' contact closures. Four TTL logic inputs on the 6000 digitally tag the audio on input and close the corresponding relay when the tagged delayed audio reaches the 6000's output. It takes all of the mathematical guesswork out of local breaks. Sonically identical to the 6000AT, the 6100 adds a host of interfaces, with AES/EBU digital I/O, ESE T-89 time code in/out/thru, Word Clock input, and RS-232 and RS-485 ports.
