LINGLING ONE IR Emitter Extender Extension Cable 3.5mm Jack - Infrared Red Blaster/Remote Control/Controller Extender Transmitter Eye - Lead/Wire-10FT (1pcs 1 IR Eye Emitter)

This does NOT work with a Denon X2400H, despite what Rufus tells you. It says in the product description that it does not work with Denon. Rufus ignored it and told me it works with Denon receivers. It may have worked with that Denon HEOS link but it does not work with an x2400h. 5 stars because I'm sure it works, it was just Amazon wasting an hour of my life routing this through the wall just to find out it doesn't work. Go back to the original review search and stop forcing Rufus on us.

Didn’t work with my device

I’ve had a need to communicate with my subwoofers over IR, unfortunately they don’t have a wired connection. I used two of these IR Emitters and stuck them on next to the subwoofers IR eye. Their cables then come back to a Y connector and then into a Harmony Hub’s IR output. The performance has been great, and I can now control my subs and put them into various presets depending on my listening. I could have used slightly longer cables in my situation, but since I needed an adapter to go into my Harmony, I just made those cables a little longer. Wish I’d tried this solution sooner.

IR repeater did not work with Formuler Android box and was going to return until the IR head broke on me when trying to remove it from the adhesive applied to the front of the TV. Don't recommend purchasing this cheap IR repeater. It's now a garbage repeater!

Does not work with a Onkyo TX-SR805.
