Since IR remote control signals need "line-of-sight" to work, you will need this extender if the equipment you're trying to control is hidden out of sight such as in a cabinet, A/V Closet, or behind the TV.

How it Works

The BlastIR USB consists of an emitter cable, a receiver, and a USB power cable.

  • Mount the receiver on or near your TV. Keep in mind that the receiver must be in the line-of-sight to wherever you will be using your remote control.
  • Mount the emitter directly over the IR sensor on the device you wish to control.
  • The BlastIR USB can be powered by either plugging the USB Cable into a USB port on your TV, or you can plug it into a power outlet by using the included DC12V adapter.

Once everything is connected, the receiver picks up the IR Remote control signal and transfers it over a small cable to the emitter.

The BlastIR USB repeater kit is dual band, which means it will work with the most IR devices. This compact BlastIR is perfect for a simple installation in which you are only hiding away a few devices (up to 4 with the Quad  emitter option). If you need to control more devices, check out the full sized BlastIR Pro.

The length of the cable between the emitter and receiver is 6 feet. The length between the USB power connector and the IR receiver is also 6 feet, so the combined length of the product is 12 feet.

Works Good

I bought a single blaster and had to call support to find out which part was the sender and which was the receiver. The instructions did not state which was which. After that was resolved it works very well.

Great Product

Pros: I just had a cabinet built and wasn't sure how to hide my components. I had no idea what I needed. Sewell Direct had so much information and helpful videos that I felt confident I had purchased the right product for my needs. Cons: noneOther: The packaging is superior. It looked like a pretty Tiffany box. I know this might sound dumb, but it made me feel like this company is very proud of their products.
