AirTools 6000 User manual
A
24-bit digital delay unit for live or syndicated
broadcast that prevents unwanted profanity
or comments from reaching the airwaves.
Keep your air clean and seamless.
Engineered by Symetrix, the AirTools 6000 offers advanced
delay technology with up to 40 seconds of user-defi nable
delay at a full 20 kHz range of stereo bandwidth. When it
comes to advanced broadcast audio delay, the AirTools
6000 offers more of the features you need at a better price.
Easily Get Rid of Unwanted Comments.
When you want to edit a comment, simply push a button.
The AirTools 6000 goes to work and your broadcast hits
the air minus the offending content.
The AirTools 6000 also includes standard features like an
Automation Control Interface and ESE TC89 time code
input and output to allow for both real and delay time
displays.
Here’s how it works:
• Connect the main programming output from any studio
console.
• When the show begins, press START. The AirTools 6000
begins digitally stretching the program creating up to 40
seconds of delay.
• You can defi ne a delay between 1 and 40 seconds,
allowing a great amount of fl exibility when it comes to editing
unwanted material.

• If a guest makes an unwanted comment, or you want to
delete content, press DUMP and keep going. The unwanted
material, up to the last 40 seconds of your broadcast,
disappears while the show goes on.
• Another way to get rid of unwanted content is with COUGH.
In the middle of a broadcast, you may need to say something
“off air” to your guests, for example, or have a quick drink of
water. Press COUGH to edit out unwanted airtime, and then
release it when you’re fi nished. The broadcast picks up again.
• If you are a network syndicator, 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 and switchovers.
• At the end of your program press EXIT and the 6000
gradually leaves the delay mode until you are in real time.
