Over the past four decades, Lectrosonics has grown to become an internationally recognized company in the areas of audio technology, DSP implementation and wireless microphone expertise. Born, bred and continuing today as a US manufacturer of precision audio components, Lectrosonics has many innovations to its credit along with several key patents including one for Digital Hybrid Wireless®. This technology, used in the majority of our wireless microphone products today, has garnered fans in many industries including motion picture, television and video production, theatre, touring musicians and houses of worship.The DM Series and now the ASPEN line, incorporating the patented Proportional Gain algorithm, push the envelope in quality, expandability and flexibility for automatic mixing and matrixing systems.

Based on cutting-edge Digital Signal Processing technology, these products have found a wide range of applications including courtrooms, boardrooms and educational facilities. By maintaining a comwithment to the design, development and production of these products in the United States, Lectrosonics has bucked recent trends towards outsourcing, and has remained profitable and even grown despite recent challenging economic times. The simple philosophy at Lectrosonics is to design and build products that exceed the demands of the most discriminating professionals, and support those products with the best customer service in the industry.

Wireless Systems from Lectrosonics

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 transwithted 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 transwithted 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.
