6100 Broadcast Audio Delay

The 6100 gives the host or producer of a talk show the power to prevent the broadcast of unwanted profanities or comments from guests, hosts or telephone callers. As the program begins, the 6100 gradually and unobtrusively delays or “stretches out” the program until up to 40 seconds of 20 kHz bandwidth stereo audio is stored in memory. When a person says something the host or producer does not think appropriate for the broadcast, he or she presses the DUMP button and a user preset length of memory is cleared, thereby preventing the unwanted audio from reaching the airwaves. Meanwhile, the host releases the offending caller from the telephone line and proceeds with the program. After the DUMP button has been pressed, the 6100 automatically begins to stretch (time expand) the program audio again until the user preset length of delay is attained.


Yes.  Have the unit serial number handy and contact or call +1 425 778 7728.

Hold down the previous, next, and home buttons in while powering up the unit.

Yes.  Have the unit serial number handy and contact or call +1 425 778 7728.

Change or adjust the delay algorithm and/or delay ratio.  Find the algorithm and delay ratio that is the most appropriate for the program material.  For more information reference the unit’s User’s Guide.

Yes.  Have the unit serial number handy and contact or call +1 425 778 7728.

Power-cycle the unit while simultaneously holding down the Previous, Next & Home buttons on the front panel.

The station or studio must be equipped with an ESE TC-89 master clock generator. The real time output of the master clock generator is connected to the 6100’s TIME CODE IN connector. The 6100 reads the incoming time code and adds to it the current amount of delay time. The time in delay (TID) is displayed on the 6100’s front panel LCD and also appears as time code at the 6100’s rear panel TIME CODE OUT connector that can be fed to a dedicated ESE clock for display of TID.

The AirTools 6100 ships standard with: AES-3 digital input and output, Word clock input, Remote Control via RS-232 or RS-485, ESE TC-89 Time Clock Reader.

The AirTools 6000 does not have these features.

The 6000 and 6100 have four internal relays that may be independently used to control station automation events. The relay closures (outputs) are triggered by input closures that can be either manual (a momentary switch closure) or electrical (TTL logic low). When an input closure takes place the audio entering the delay at that moment is ‘tagged’. When the tagged audio reaches the output of the delay its corresponding relay closes for a time equal to the length of the input closure.

The bypass is engaged and ‘BYP’ is commonly mistaken for ‘64P’ on the display.

Yes. See wiring and pinout information in the User’s Guide.

As an example of how they are used together assume that a local talk show switches to syndicated network news every day at 12:00:00 (noon). Assume one of the 6100’s Automation Control Outputs controls a router that switches the air signal from the local studio audio to the network audio. A manual push button is wired to the 6100’s corresponding automation control relay. The air talent views the ESE clock displaying TID (time in delay which is real time plus the amount of delay added by the 6100). At 11:59:00 (TID) the air talent ends his sentence and presses the designated push button. The audio built up in the 6100 continues to play out until 11:59:00 (real time) at which time the relay closes and switches from local audio to network audio. The powerful combination of 6100, TC-89 master clock generator and TC-89 time clock reader allow the air talent to make a perfect transition from delay audio to real time without the need for manual time calculations.

Yes, although custom wiring is required. You would do this by wiring to the contact closure and ground pins on the back of both units in parallel, and then wiring the remote LED indicator pins from just one of the units. The units can not and will not be in perfect sync (start and exit build times), however, the dump, cough, start and exit functions will be triggered at the same time on both units from one remote.

The outputs are parallel, but for the inputs you must select either analog or digital.
