IR signal repeater SW-29311

Extend and Route Remote Control Signals

The BlastIR is designed to get your remote control's signal to where it needs to go. Since remote control signals (IR) need "line-of-sight" to work, you will need this extender if the equipment you're trying to control is not in sight. You'll need to extend your IR signals, especially if your TV is wall-mounted.

Sewell's IR extender kits provide all the parts you need in one convenient package to send an IR signal from the comfort of your couch to wherever you store your equipment.

Ir Guide

How This Works

This kit includes an IR receiver, a connecting block (which also serves as a signal repeater), and IR emitters. The IR receiver is a small inconspicuous device that you can mount on your HDTV's bezel or anywhere else in the room where you will want to point your remote. It is small and very easy to hide, but must be in line-of-site to your couch (or wherever you will be sitting when using your remote control). This receiver receives your remote control's commands and sends the signal over 3.5mm mini stereo wire to the connecting block (which you can hide behind your wall).

The connecting block then actively repeats and sends the same signal through all IR emitters connected to the block. Four emitters come with the kit and each emitter features two "eyes". Each eye blasts out the same IR signal, and you can tape them directly to your equipment or simply fix them to a nearby shelf or wall (or even the back of the door of your video closet).

Dual-IR-EmitterDual-IR-EmitterWe also recommend additional Dual Headed Emitters in the event you have more video source equipment than this kit can handle. These emitters plug into this kit's connection block using the 3.5mm connection.


If you're having troubles with your BlastIR, there are some simple things you can do to troubleshoot the problem. This video will walk you through the steps. Or you could check out this article about troubleshooting the BlastIR.

Works Great

Pros: It just works.

Cons: A little confusing which port to plug the power supply to. One didn't work, the other did - no big deal.

Other: I ordered the unit and payed for the cheapest shipping method. It showed up at my house 7 days later. Set everything up and it worked like a champ. No problems. It workes better that the one I replaced. One unanswered question that I had was about the range of the IR emitters. I mounted 1 of the dual IR emitters to my closet wall which faces my equipment and is about 30" away. That is all I had to do, they are able to control everything. I have a Sony brand receiver and DVD player. I also have a COX DVR/Cable box. Everything works great from way across the room. I am very happy with this product. Setup took me minutes. By the way if you didn't know, you can see IR light if you look through your digital camera view screen. It makes troubleshooting easier.

See all 5 questions


how long is the 3.5 mm ir reciever wire that would go under my tv i need it to be 12 feet is it that long? not the wires that hook to the componets but the one that comes out of the block to point the remote control to.


the cable is 3 meters(about 9 feet). The cable is the same as a 3.5mm stereo cable. you can easily extend this by getting an additional female to male stereo cable like the 3.5mm Stereo Cable . you could basically get this in any length to fit your needs. If you would like this cable shorter, you could use the 6 foot Stereo extension cable

Would this system work for a PS3 and the game controllers?


This unit is designed for Audio/Video IR remote controls. The regular PS3 controller is not IR, so this will not work with that setup.

I set up the Blast IR kit but it does not work. The connecting block has a green light and the transmitter has no light when pointing the remote. Could you help me out? Thank you


Sorry for the confusing setup. The green light indicates that the status of your system is good (hence, the "status" label next to the port). The other port that says 12V DC is the port that you need to plug into to power the device. That should fix your problem.
