The Lectrosonics Digital Hybrid Wireless® uses innovative 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 information 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 compromised.

Under weak RF conditions, the received signal degrades 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.

Lectrosonics, recognized the world over as a leading manufacturer of wireless microphone systems and audio processing products, is pleased to announce three new products in the company’s L Series ‘Large Bandwidth’ line of wireless microphones. The new L Series units all share a wide tuning range of three standard Lectrosonics blocks, or 67.5 to 76.8 MHz, depending on the specific frequency band, and employ Lectrosonics’ patented Digital Hybrid Wireless® technology for compandor-free audio along with compatibility modes for interoperability with older analog systems. The new L Series product group consists of the LMb and LT beltpack transmitters, and the LR miniature receiver.
