The Lectrosonics Digital Hybrid Wireless TM uses in-
novative technology to combine the new advantages of
digital audio with the advantages of analog RF trans-
mission, thus delivering the superior sound quality of a
digital system and the excellent range of an analog sys-
tem. A proprietary algorithm encodes the digital audio
information into an analog format which can be trans-
mitted in a robust manner over an analog FM wireless
link. The receiver employs state-of-the-art filters, RF
amplifiers, mixers and detector to capture the encoded
signal and a DSP recovers the original digital audio.
This digital/analog hybrid technique has some very
beneficial properties. Because the information being-
transmitted is digitally encoded, immunity to noise is
much higher than a compandor can offer. Because the
encoded audio is sent in analog format, spectral and
power efficiency and operating range are not compro-
mised.
Under weak RF conditions, the received signal de-
grades gracefully, like an analog system, delivering
as much usable audio as possible at maximum range.
Since the audio is free of compandor artifacts, pumping
and breathing problems are also greatly reduced.
