IR Receiver - 3.5mm jack for Home theater Processor

[JRace]

I have a Rotel RSP-1069 that I want to keep behind closed doors.
It has a "3.5mm IR receiver input" that I could use....if I could find one!

Anyone know where I could locate such a thing?

Thanks,

This is what somebody in another forum suggested, but it doesn't seem to have a plug. Xantech may have more info on what you need to do that.

Or maybe you can just wire up an IR module salvaged from a dead VCR or DVD player.

You can find IR receivers with 3.5mm plugs on e*ay for $20.

Is it a stereo or mono jack on the Rotel? If it is stereo, Xantech has a model with a 3.5mm stereo plug, tip=IR, ring=GND, sleeve=+12V. I would suggest checking if the Rotel's jack has +12V across the sleeve and ring. If the sleeve and ring are shorted (i.e. a mono jack), then it is most likely an IR input jack, usually tip=IR, sleeve=GND. If this is the case, a connecting block will be needed to give power to the IR sensor.

No power, looks like I need a connecting block.

I have a salvaged 3pin IR receiver from an old VCR.

Any tips on what I need to supply power to get this working?
FWIW there is an available 12v trigger on the processor.

The 3 pin IR receivers will remove the carrier frequency from the signal. If necesary, it can be re-inserted using an oscillator, such as a 555 timer. The attached diagram is one way to get you going. If the Rotel does not need the carrier, the circuit can be made much simpler.
