SRb5P and SRb Dual Receivers

LECTROSONICS, INC.

Digital Hybrid Wireless

The Lectrosonics Digital Hybrid Wireless

uses innova-

tive 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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lters,RFampliers,

mixersanddetectortocapturetheencodedsignaland

a DSP recovers the original digital audio.

Model Differences

Thisdigital/analoghybridtechniquehassomevery

benecial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efciency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.
