Works with: BlastIR (SW-29311); BlastIR Wall Plate Receiver Kit (SW-29309); BlastIR Wall Plate Kit (SW-29310); BlastIR Wireless Kit (SW-29310). Use this quad emitter component in conjunction with other equipment (such as an BlastIR Extension Kit) to increase the number of video sources you can control from a distance with a regular remote control. Since all remote controls that come with TVs and HDTVs are Infrared (IR), it requires "line-of-site" to operate. This component, along with a BlastIR Extension Kit allows you to put your video sources (DVD player, Blu-ray player, DVR, etc) out of site so you can mount your TV cleanly to a wall. Check out the BlastIR Extension Kit for more details.
