Unfortunately, many digital 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 try to reconstruct the carrier frequency using a simple manual digital “mixer.”
Analog IR repeater systems are no better—they simply boost the noise along with the signal. Both result
in incomplete or incorrect IR signals which the set-top box often cannot make sense out of, and a lot of
frustration and expense for a system designer when the cable or satellite TV system simply won’t work
with its own remote control in an installed system.
Xantech takes no shortcuts here. We use a better-quality advanced digital signal processor circuitry to
accurately preserve the original carrier frequency’s integrity. By doing so, a Xantech IR receiver always
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.
5. Better design and 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.
Internally, Xantech receivers use an internal metal shield and precision circuit design to keep interference out.
A dual-lens optical filter more effectively removes unwanted light artifacts before the signal even reaches the
sophisticated and sensitive internal electronics. All Xantech IR products are designed and tested to meet all
applicable FCC and CE standards for interference, and all of them are built using environmentally-responsible
methods and materials and are RoHS compliant.
This attention to both component quality and advanced technology is ultimately what makes a superior IR
product— and what makes it a “Xantech.”
