The Lectrosonics Digital Hybrid Wireless

uses innovative technology to
combine the advantages of digital audio with the advantages of analog
RF transmission. The result delivers the superior sound quality of a digital
system and the excellent range of an analog system.
A proprietary algorithm encodes the digital audio information into an ana-
log 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 compromised.
Under weak RF conditions, the received signal degrades gracefully, like
an analog system, delivering as much usable audio as possible at maxi-
mum range. Since the audio is free of compandor artifacts, pumping and
breathing problems are also greatly reduced.
