Kill dead air dead.

Wait, what?
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 really enjoy those unplanned trips to kick Murphy out of the studio, you might consider a less sleep-depriving way to deal with off-air emergencies. We’d like to introduce you to the Failsafe Gadget.
The Failsafe Gadget is a simple 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 the switching, or reset the Gadget.

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. Dynamic programming with a relaxed pace may want lower thresholds and longer delays, while compressed and tight programming may tolerate higher thresholds and shorter delays. The idea is to set the threshold and delay so that normal gaps and quiet passages will not trigger the sensor.

A bicolor LED gives 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 awhile, a silence event is underway. A front-panel sensor bypass switch lets you put the Failsafe Gadget in manual mode; perfect for formats that only need backup during automated segments.

You can use the Failsafe Gadget in reverse, too. Plug your main programming into the B input, select the B-A recovery mode, and connect an alternative audio feed to the A input. The Gadget will stay on B until there is audio on the A input, at which point it will switch to A until that audio is finished, when the Gadget will return to B. Perhaps you have some occasional audio event which must override normal programming. The Failsafe Gadget easily accomplishes this by detecting the presence of signal.

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 longevity. And like every other Angry Audio product, the Failsafe Gadget is completely immune to RF interference.

The Failsafe Gadget looks great in the rack too. The optional Rack Mount Kit has room for two Gadgets in 1RU. A blank is provided if you only want to rack mount a single Gadget.
An optional Wall Mount Kit provides the brackets and hardware to attach your Failsafe Gadget to a desktop, cabinet or any suitable flat surface.
