Featuring five significant advances in IR control to achieve their remarkable sensitivity, performance and reliability in a wide variety of installation environments. The LCD/CFL friendly Hidden Link IR Kit includes an HL85 table top infrared receiver, 1x4 connecting block and 4 IR emitters.
Native Carrier Frequency Transmission Circuitry
Nearly every IR system relies on a carrier frequency to “carry” the commands to their destination. Some consumer electronic devices, especially digital cable and satellite TV boxes, are very picky regarding carrier frequency accuracy. At times, they may not accept remote commands unless precisely the right carrier frequency is present.
Unfortunately, many IR repeater systems take a technical short-cut and simply strip away the carrier frequency upon reception instead of intelligently identifying and removing the unwanted noise and interference from it—and then attempt to regenerate or replicate the carrier frequency. This can result in incomplete or incorrect IR signals and a lot of frustration and expense for a system designer.
Xantech takes no shortcuts here. Rather than trying to make a copy of the carrier frequency to compensate for inadequate parts and circuit design, Xantech uses better-quality components and circuitry that can accurately process the original carrier frequency. By doing so, a Xantech IR kit eliminates the noise and interference instead of the carrier itself, and transmits the original IR signal in its correct form to the rest of the system. The result is a dead-on accurate signal transmission— minus all the noise and distortion.
Overall Build Quality
Essential in getting the most out of Xantech’s technology advantages is an unusually high level of component quality and manufacturing precision not found in competitive IR products. Every link in the system chain, from power supply to IR emitters, is made from ultra-high quality electronic parts and materials and selected for performance, electronic and/or optical integrity, and long-term reliability. This attention to both component quality and advanced technology is ultimately what makes a superior IR product— and what makes it a “Xantech.”
Error Correction Circuitry
Xantech IR receivers actively monitor and confirm an infrared signals validity by comparing it to typical remote control signal patterns. By doing this, unwelcome spurious or very high frequency interference can be easily ignored, while validated but distorted IR signals can be quickly repaired and purged of undesirable noise. The result is the most faithful reproduction of the original IR signal that present technology allows.
Automatic Gain Control (AGC) Circuitry
A Xantech IR receiver also constantly studies the ambient light level in the environment, and automatically (and rapidly) re-calibrates its own sensitivity so it can more accurately discriminate between the wanted remote signals and unwanted noise from sources such as TV’s, lighting and even the sun.
Sophisticated Adaptive Filtering Circuitry
Xantech has extensively analyzed the IR characteristics of the vast majority of consumer electronics product types, which shows that nearly all of them operate using a carrier frequency between the 25 kHz and 60 kHz range. Frequencies above 60 kHz consist mostly of random noise generated by CFL lighting as well as LCD and plasma displays. Through this exhaustive and on-going research, Xantech is able to build-in an intelligent, accurate, and effective filtering mechanism into each of its IR receiver technologies which enables a Xantech receiver to more electively “look” at an IR source while rejecting those frequencies without any useful information.
