The Lectrosonics Digital Hybrid Wireless
®
uses innova-
tive technology to combine the advantages of digital
audio with the advantages of analog RF transmission,
thus delivering the superior sound quality of a digital
system and the excellent range of an analog system. A
proprietary algorithm encodes the digital audio informa-
tion into an analog format which can be transmitted 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 what a compandor can offer. Because
the encoded audio is sent in analog format, spectral
and power efficiency and operating range are not com-
promised.
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.
