A little bit of Lectrosonics history...

Founded in 1971, Lectrosonics began with the manufacture of portable

sound systems sold under the Voice Projector

registered trademark. The

first product line consisted of a self-contained lectern/sound system and two

over-the-shoulder portable sound systems.

In 1975 the first wireless microphone systems were introduced to audio

visual markets. The first system was a lavalier system consisting of a belt-

pack transmitter and matching receiver. Soon after this, the receiver was

equipped with a rechargeable battery pack to allow it to be used with the

portable sound systems. A year or so later a special version of the receiver

was designed to be built inside of one of the lecterns providing a completely

cordless, wireless portable sound system in a lectern configuration. In

keeping with the "total portability" concept, the first self-contained speaker/

amplifier/wireless system was developed. The advent of wireless microphone

products introduced new prospective markets and set the stage for the future

direction of engineering. The first UNICHANNEL

receiver was designed

with ultra-narrow band crystal IF filtering to eliminate interference.

By the early 1980's, wireless microphone products had come to dominate the

growth of the company, leading to further investment in engineering. The

first VHF high band wireless systems were introduced in 1987, taking the

proven UNICHANNEL

design to a higher frequency band. The product

line expanded rapidly over the following 5 or 6 years, leading to the

introduction of UHF wireless systems in 1993.

In 1989 the first automatic mixer products were introduced. The most recent

models include an advanced microprocessor controlled mic/line mixer that

provides an adaptive algorithm* that keeps track of microphone activity to

prevent background noise from affecting the mixing action. Future products

in the audio group will include even more advanced microprocessor and

computer controlled components for automation of entire sound systems.

Lectrosonics remains an engineering driven company. Ongoing efforts

continuously produce new designs with the latest technology in electronics

and mechanical engineering.
