Wireless

Surround sound
minus the 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.

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.

Wireless made simple

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.

The technology explained

KEF have developed innovative new technologies to deliver
high-quality wireless audio, while at the same time avoiding
signal interference:

A narrow signal band is used that is sufficient enough for high­quality 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.
