Digital Hybrid Wireless

The Lectrosonics Digital Hybrid Wireless

uses innova-

tive technology to combine the new advantages of digital

audio with the classic advantages of analog RF transmis-

sion, thus delivering the superior sound quality of a digi-

tal system and the excellent range of an analog system.

A proprietary algorithm encodes the digital audio infor-

mation 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 bene-

ﬁcial properties. Because the information being transmit-

ted 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 compromised.

Unlike traditional analog compandor systems, no arti-

facts are introduced under strong RF conditions.

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.
