Before we get started, let’s talk about what exactly IR is. IR stands for infrared, which is a form of light not visible to the naked eye (stop giggling). Most of our electronic equipment that uses a remote control has been built to pick up on these frequencies. For all intents and purposes, just know that our remotes shoot infrared light to our equipment; this light is then received and converted into electrical signals which our electronics can understand. Fancy, right? Now that you fully understand with expert knowledge how our remote controls boss our electronics around (a bunch of bullies if you ask me), let’s move on to why you would need an IR extender or repeater in your home theater set up.
