What’s an IR Extender?
Imagine you’ve just built your dream theater using the most current cable box, a new Blu Ray player, and also a wonderful sound system. Of course, you do not want it all straight beneath your Television because it is too clunky and also the wires are often messy. So you move it into a cabinet either nearby or in a diverse room.
Difficulty: considering the fact that you moved your devices, your remote isn’t able to control your cable box, your Blu Ray player, or your good sound system. Remotes use IR (Infrared) signals to communicate, these signals only operate via line of sight and can fail when something is disrupting that line of sight.
Option: An IR Extender can route the IR signal out of your remote control so you are nevertheless able to control your theater even though it is actually out in the line of sight.
Choosing an IR Extender
There are 2 concerns which you require to possess answered to understand when the IR extender is appropriate for you.
1. Will the IR extender perform with my devices?
2. May be the IR extender ideal for my setup?
1. Will the IR extender work with my devices?
You are able to usually answer this question really easily by seeking to see in the event the IR extender is Single Band or Dual Band. Dual Band ordinarily is able to extend IR for the most prevalent products like Blu Ray players and projectors, and if it has RC-MM protocol then it must be capable to control majority of cable boxes.
What is the difference among dual band or single band?
Each and every IR signal features a distinct frequency. These frequencies are measured in kilohertz (kHz). There are actually two general frequency ranges that all devices use. These ranges are referred to as bands. The very first band incorporates the frequencies ranging from 33-43 kHz, whilst the second band ranges from 44-60 kHz. In order for you to be capable to control your device (just like the Television), your remote and Tv will have to work on the same frequency.
Single Band IR Extenders: These only compatible with one frequency are named Single Band IR extender. Usually, Single Band frequencies are only 33-43 kHz which works with most DVD and Blu Ray Players.
Dual Band Extenders: Dual band extenders operate on both frequencies (33-43 kHz and 44-60 kHz), making them operate with most all devices. See Sewell’s list of Dual Band IR Extenders.
Keep in mind: If an IR extender isn’t compatible with If the frequencies, it can not pass the signal and you’ll not have the ability to control your device. Make sure to verify the frequencies.
RC-MM Support
RC-MM is actually a newer IR protocol that was developed to become used with wireless keyboards and mice. The protocol uses much shorter waves than a common IR signal and uses significantly less power. As a result of shorter wave lengths and reduced energy some IR sensors are unable to process the signal.
RC-MM protocol is becoming far more prevalent with significant brands. It can be used on AT&T U-verse cable box, Cisco Explorer 4642HDC, IPN 4320, IPN 330HD as well as the Motorola VIP series and a growing number of products.
2. Which IR Extender is very best for my Setup?
Extending IR signal is only half with the issue. At Sewell we have designed multiple IR extenders for a variety of distinctive set-ups. All of our IR Extenders are dual band and need to operate for most devices. Here are some concerns you needs to be asking and also a few recommendations for these key factors in setups.
