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:
