KEF 5000 Series KHT5005.2 User manual

5000 series
Wireless
A narrow signal band is used that is sufficient enough for high-
quality audio transmission yet perfect for finding a path through
the congested environment of a home filled with potentially
conflicting devices.This narrow band is a feature of HFADPCM
(High Fidelity Adaptive Differential Pulse Code Modulation), and
along with advanced error correction technology ensures an
exceptionally robust delivery of CD-quality audio between the
transmitter and receivers.
The system detects other transmitters in the 2.4GHz frequency
- such as cordless phones, wi-fi routers and microwave ovens -
and ‘hops’ out of the way of potentially conflicting signals.With
this technology, known as AAFHSS (Advanced Adaptive
Frequency Hopping Spread Spectrum), a processor constantly
monitors several channels at a time and continually switches to
the strongest available to ensure a constantly pure signal.
It’s all done in milliseconds so you don’t notice it’s happening: so
nothing gets in the way of your enjoyment.
KEF have developed innovative new technologies to deliver
high-quality wireless audio, while at the same time avoiding
signal interference:

Wireless
Surround sound
minusthe cables
If the problem of hiding lengthy cables has restricted where you put
your loudspeakers, now you have the freedom to locate them
virtually anywhere you wish. Using KEF’s extensive research
capability, we have developed a remarkable innovation in audio
quality and convenience that at last makes high-performing wireless
speakers a reality.
So why aren’t wireless speakers already commonplace? The answer
lies in the fact that, as others have found, ensuring a reliable signal
that’s free from interference in homes full of potentially conflicting
devices hasn’t been easy.
The risk of signal interference exists because the only broadcast
space available for wireless systems is the 2.4GHz frequency, the
same one used by wi-fi routers, bluetooth devices, some digital
cordless phones and even microwave ovens. Because it’s such a
widely used frequency, it has been hard to ensure that wireless
speaker systems can operate free from signal drop-outs.
KEF’s solution is a remarkable combination of signal transmission,
reception and processing technologies. Superb signal reliability is
delivered with CD-quality sound that is a match for even the most
demanding audio systems.
It is of course essential that even the most high-performing
technology is free from complicated set-up and operating
procedures. So we have made sure you’ll be up and running in
minutes thanks to simple connections, with the only additional
requirement of delivering mains power to the transmitter and
receiver units through discrete power adaptors.
Once in use, you can forget about the technology because
automated signal processing means there are no buttons or dials to
get in the way of enjoying great sound.
Now with a choice of wireless integrated into the KEF 5000 Series,
you can enjoy the convenience of a cable-free solution with no loss
of signal and the sound quality you’d expect from KEF.
Wireless made simple
Go wireless with the
KHT5000 Series
Our wireless system is now available for the high quality
KEF Home Theatre 5000 Series 5.1 surround sound system. The
optional transmitter comes with receivers that can be integrated
into the two rear speakers, whether you choose floor or desk stand
options.The rear speakers can also be purchased separately for use
in any surround system, and they make an excellent audiophile-
standard stereo pair.
For existing 5000 Series owners, it’s easy to adapt your system to
wireless operation. The wireless receivers and transmitter can be
purchased as a separate upgrade package: the receivers simply
require assembling into the speaker cabinets to convert them to
wireless operation. And, as with the package for new system buyers,
the receivers are available in either matt silver or high gloss black
finishes to complement your system’s design.
