What's an IR Extender?

Picture you've just built your dream theater together with the most up-to-date cable box, a new Blu Ray player, and a terrific sound system. Naturally, you do not want it all directly below your Tv because it is also clunky and also the wires are normally messy. So you move it into a cabinet either nearby or within a unique area.

Challenge: since you moved your devices, your remote isn’t capable to control your cable box, your Blu Ray player, or your excellent sound system. Remotes use IR (Infrared) signals to communicate, these signals only function via line of sight and can fail when anything is disrupting that line of sight.


Solution: An IR Extender can route the IR signal from your remote control so you're nonetheless in a position to control your theater despite the fact that it's out on the line of sight.


Picking an IR Extender

There are actually 2 concerns that you simply need to have to have answered to know in the event the IR extender is proper for you.


1. Will the IR extender work with my devices?

2. Is definitely the IR extender very best for my setup?

1. Will the IR extender operate with my devices?

You'll be able to typically answer this question very quickly by wanting to see if the IR extender is Single Band or Dual Band. Dual Band usually is able to extend IR for probably the most prevalent products like Blu Ray players and projectors, and if it has RC-MM protocol then it ought to be in a position to control majority of cable boxes.


What's the distinction between dual band or single band?

Every IR signal has a distinct frequency. These frequencies are measured in kilohertz (kHz). You'll find two general frequency ranges that all devices use. These ranges are called bands. The very first band includes the frequencies ranging from 33-43 kHz, whilst the second band ranges from 44-60 kHz. In order for you to be able to control your device (just like the Television), your remote and Tv have to work on the similar frequency.


Single Band IR Extenders: Those only compatible with one frequency are referred to as Single Band IR extender. Commonly, Single Band frequencies are only 33-43 kHz which performs with most DVD and Blu Ray Players.


Dual Band Extenders: Dual band extenders operate on each frequencies (33-43 kHz and 44-60 kHz), creating them perform with most all devices. See Sewell’s list of Dual Band IR Extenders.


Keep in mind: If an IR extender just isn't compatible with In the event the frequencies, it will not pass the signal and you'll not be capable of control your device. Make sure to check the frequencies.


RC-MM Help

RC-MM is really a newer IR protocol that was created to become used with wireless keyboards and mice. The protocol uses significantly shorter waves than a common IR signal and uses less energy. As a result of shorter wave lengths and reduced energy some IR sensors are unable to process the signal.


RC-MM protocol is becoming a lot more prevalent with major brands. It truly is used on AT&T U-verse cable box, Cisco Explorer 4642HDC, IPN 4320, IPN 330HD plus the Motorola VIP series and also a growing number of products.


2. Which IR Extender is greatest for my Setup?

Extending IR signal is only half of your trouble. At Sewell we have designed multiple IR extenders for a variety of various set-ups. All of our IR Extenders are dual band and must function for most devices. Here are some concerns you needs to be asking and a few recommendations for those key factors in setups.
