5000 seriesWirelessA narrow signal band is used that is sufficient enough for high-quality audio transmission yet perfect for finding a path throughthe congested environment of a home filled with potentiallyconflicting devices.This narrow band is a feature of HFADPCM(High Fidelity Adaptive Differential Pulse Code Modulation), andalong with advanced error correction technology ensures anexceptionally robust delivery of CD-quality audio between thetransmitter 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.Withthis technology, known as AAFHSS (Advanced AdaptiveFrequency Hopping Spread Spectrum), a processor constantlymonitors several channels at a time and continually switches tothe strongest available to ensure a constantly pure signal.It’s all done in milliseconds so you don’t notice it’s happening: sonothing gets in the way of your enjoyment.KEF have developed innovative new technologies to deliverhigh-quality wireless audio, while at the same time avoidingsignal interference:The technology explainedPL1646ENwww.kef.comGP Acoustics (UK) Ltd., Eccleston Road,Tovil, Maidstone, Kent ME15 6QP U.K. Tel: + 44 (0)1622 672261 Fax: + 44 (0)1622 750653GP Acoustics (US) Inc., 10 Timber Lane, Marlboro, New Jersey 07746 U.S.A.
