Hi all!
Did try to use Mirror TV "Ad-Notam" back IR input for plug in IR sensor
3.5 mm stereo: Speaker Craft and Xantech 480 not working.
Do I need different configuration on 3.5 st. plug or different sensor ?
Thanks!!

Rufen Sie die Fabrik an.

Well folks...

Despite the fact that the new AppleTV doesn't have a digital audio out, or a BT remote. (Thankfully it has IR input.)

I think this would be a great selling point...

Open up that documentation and look at it.
Any time an IR receiver is called for, the socket will have connections for ground, IR signal, and supply voltage for the receiver. If you use a tip and ring connector, you'll short together the tip and sleeve connections of the socket.

In order to prevent the power from being shorted out, it's necessary to put the power on the tip. That's just what they did. If you use a tip and ring connector, you'll only short out the connection that should have signal on it, so there's not damage to the TV, but of course it won't work.

If you plug in an IR source with the signal on the tip, the TV will feed 5V into your IR source. This might damage the IR source itself.
