IR Repeater Kit, ir Repeater System，IR Remote Control Extender .Supports up to 50 feet.

The media could not be loaded.  I can finally have the cabinet closed. Volume control works well with this passthrough. A nice amount of inputs and outputs, seems like a very versatile device.

I make props for performers that have IR remotes and sometimes it's necessary to have multiple transmitters around the stage to make sure a signal reaches the prop regardless of where it is. This unit works well enough for that purpose (I've tested it with both RC5 and NEC protocols at 38 kHz) that I feel like I can recommend it to my customers, but the biggest deficiency seems to be that despite the unit offering 3 inputs and 6 outputs, there's apparently no way to buy the extra receivers and transmitters separately. You get one receiver and four transmitters and that's it.
