KEF is delighted to announce the introduction of a high-quality wireless system especially designed for the KEF Home Theatre 5000 Series.

For existing 5000 Series owners, itÂ’s easy to adapt your system to wireless operation. The rear speakers can also be purchased separately for use in any surround system.

The new KEF Wireless 5000 series delivers CD quality audio with 'Intelligent' Interference Free Signal Technology.

Now there is no need for owners or new purchasers of this system to be concerned about lengthy speaker cables running from the amplifier to the rear speakers.

In order to achieve real full-bodied audiophile sound reproduction KEF has developed a leading edge 2.4Ghz wireless transmission technology that uses the most advanced error protection and sophisticated 'intelligent' adaptive frequency hopping, ensuring an interference free signal. This makes certain that the transmission is not affected by such things as microwave ovens, mobile or digital cordless telephones, and wireless LAN routers, while still providing the superior sound quality demeaned by true audiophiles.

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 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, know 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.
