Wanna Play "Guess What's in the Grey Box?"

Taken at a nearby radio station. Going to be my responsibility soon.

"Clean Box Pro"? Not quite...

Given all of the XLR connectors spraying out of that box, I would guess it is somebody's half-assed distribution amplifier (or passive splitter). Maybe to split off air chain audio to different destinations.

EAS take over relay?

Run!

Second this. On Air Audio Override Relay for the EAS.

Let's play "what wasn't in the budget" instead...

[ncradioeng]

A box was in the budget at least. Why not use the Endec in/out audio connections if that is what it is?

[Shane]

TFT EAS 911s do not have audio in/out. That's in a separate box, either TFT's or your own home brew. So perhaps this is that.

[awsherrill]

Pretty sure that is a Sage Endec in the pics, which does have its own interrupt relays.

The box could be someone's homebrew version of a multi-station relay gismo. It does kinda look like there is a pair of wires between the box and the Endec relay outputs.

No, but why don't you post a schematic with an explanation of the circuitry.

The LPFM I take care of used to have a home brewed interrupt in a brown metal box for this very reason. The TFT 911D they had didn't come with an interrupt relay. It was retired when the CAP requirement came around and a new EAS unit with built-in interrupt was installed.

[NECRAT]

The O.P. hasn't been back since he posted this... in a couple of days, I'll rattle his cage!

[KPJL FM]

Whatever it's supposed to be, there's probably a couple of spiders and dead crawly things in there.

[abwdvm]

There are 2 DPDT relays inside..... EAS control. Thanks for playing
