How you can Select the correct IR Extender

What exactly is an IR Extender?
Consider you've just built your dream theater with all the newest cable box, a brand new Blu Ray player, plus a wonderful sound system. Naturally, you do not want it all straight below your Tv because it is also clunky as well as the wires are always messy. So you move it into a cabinet either nearby or in a different space.

Problem: considering the fact that you moved your devices, your remote is not able to control your cable box, your Blu Ray player, or your excellent sound system. Remotes use IR (Infrared) signals to communicate, these signals only operate via line of sight and can fail when a thing is disrupting that line of sight.

Resolution: An IR Extender can route the IR signal out of your remote control so you are nonetheless capable to control your theater despite the fact that it is out of your line of sight.

Choosing an IR Extender
You will find 2 concerns that you simply will need to possess answered to understand in the event the IR extender is proper for you.

1. Will the IR extender perform with my devices?
2. May be the IR extender finest for my setup?
1. Will the IR extender work with my devices?
You can typically answer this question pretty simply by planning to see if the IR extender is Single Band or Dual Band. Dual Band generally is capable to extend IR for one of the most common products like Blu Ray players and projectors, and if it has RC-MM protocol then it ought to be capable to control majority of cable boxes.

What is the distinction among dual band or single band?
Each IR signal has a distinct frequency. These frequencies are measured in kilohertz (kHz). You'll find two basic frequency ranges that all devices use. These ranges are called bands. The very first band consists of the frequencies ranging from 33-43 kHz, when 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 Television will have to function around the identical frequency.

Single Band IR Extenders: Those only compatible with one frequency are called Single Band IR extender. Typically, Single Band frequencies are only 33-43 kHz which functions with most DVD and Blu Ray Players.

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

Remember: If an IR extender is just not compatible with In the event the frequencies, it can not pass the signal and you will not be capable of control your device. Make sure you verify the frequencies.

RC-MM Help
RC-MM can be a newer IR protocol that was created to become used with wireless keyboards and mice. The protocol uses much shorter waves than a standard IR signal and uses significantly less power. As a result of shorter wave lengths and reduced energy some IR sensors are unable to procedure the signal.

RC-MM protocol is becoming far more prevalent with significant brands. It is used on AT&T U-verse cable box, Cisco Explorer 4642HDC, IPN 4320, IPN 330HD along with the Motorola VIP series in addition to a growing number of products.

2. Which IR Extender is finest for my Setup?
Extending IR signal is only half of the trouble. At Sewell we have designed multiple IR extenders for a variety of distinct set-ups. All of our IR Extenders are dual band and should really operate for most devices. Here are some queries you needs to be asking and a few recommendations for these key factors in setups.
