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.
