Technical superiority
Almost all A/V IR remote controls operate over a band-
width of 25kHz-60kHz, where they generate carrier fre-
quencies to communicate with their corresponding A/V
components.
Xantech’s advanced circuitry in its 85 & 95-series IR
receivers ensures that all carrier frequencies are faith-
fully transmied and that the sensive IR signal is not
lost in the interference generated by plasma TV’s,
LCD/LED TV’s, and compact fluorescent lighng (CFL’s).
That means all components will work properly under a
wider range of condions and over greater ranges.

Updated IR components & kits 2010
The new 95 and 85 series IR kits from Xantech feature five significant advances in IR control to achieve their remarkable sensivity, perform-
ance and reliability in a wide variety of installaon environments. Xantech is the only manufacturer building an IR product line around this level
of advanced circuit design. IR is a crucial control “backbone” in nearly every A/V system installaon, and Xantech is commied to IR that works
perfectly every me which demands such a no-compromise approach. If it is an IR problem and Xantech can’t solve it, nobody can.
Error Correction circuitry:
Xantech IR receivers actively monitor and confirm an infrared
signal’s 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 dis-
criminate 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.
Native Carrier Frequency Transmission circuitry:
Nearly every IR system relies on a carrier frequency to “carry” the
commands to their destination. Some consumer electronic de-
vices, especially digital cable and satellite TV boxes, are very picky
regarding carrier frequency accuracy: 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 inter-
ference 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.”
