Dead air is every broadcaster’s worst nightmare. Equipment fails, lightning strikes, humans make mistakes. And for some reason, dead air often favors the dead of night. Unless you enjoy those unplanned midnight sprints to your silent station, you’re gonna love the Failsafe Gadget.
The Failsafe Gadget is a stereo A/B switch. Normally, the Main (A) source is fed to the output. A sophisticated sensor monitors the Main source constantly. If silence is detected, the Backup (B) source is switched to the output. The user can select whether the unit will switch back to Main if the audio returns, or whether it should remain on Backup until manually switched.
Connect your studio to the Main input and send the output to your transmission system. Backup audio sources might be a second computer, a looping CD player, even an iPod shuffling a playlist. In addition to audio switching, a logic output from the Failsafe Gadget can activate a device or alarm if silence is detected. Logic inputs are provided to remote switch the unit.
A recessed rotary switch allows you to set the threshold of the silence sensor. Another rotary switch gives you control over the duration of the silence before the sensor takes action. A bicolor LED gives a clear status of the audio. Green is normal, above threshold. Some red flashing is normal during quiet passages and transitions, but if it stays red for a while, a silence event is underway. A front-panel sensor bypass switch lets you put the Failsafe Gadget in manual mode.
The Failsafe Gadget’s audio switching path is completely passive, using sealed relays with gold contacts. The enclosure is powder-coated steel. The power supply is internal (no wall wart). All components are premium, selected for performance and long life. And like every other Angry Audio product, the Failsafe Gadget is completely immune to RF interference.
You can use the Failsafe Gadget in reverse as an audio controlled relay too. Perhaps you want a source automatically on the air whenever audio appears. Easy. Just feed your regular programming into the B input and this source into the A input. Place the recovery switch in the A<>B position and now whenever there is audio on your source, it will override your regular programming. Set the timer for a short delay and when the source goes silent again, normal programming will resume.
