Lectrosonics is a technique of professional sound production.
Technical Details
Lectrosonics systems operate with digital hybrid modulation, offering 24-bit/48kHz audio quality with a dynamic range of 134 dB. Standard transmission power is 100 mW, with an optional 250 mW. Typical latency is under 2.9 ms. The SmartTune system automatically scans available frequencies and avoids interference. Digital Hybrid Wireless technology combines analog FM transmission with digital companding. Battery life reaches 8-12 hours depending on the model (LMa, LT, SMQV). The devices are splash-proof up to IPX4.
History & Development
Gordon Moore and Larry Fisher founded Lectrosonics in 1971 in Rio Rancho, New Mexico. The first commercial product in 1973 was a wireless system for live performances. In 1982, they entered the film market with the R-1a receiver. The 100 series established the UHF standard for film productions in 1995. In 2010, Digital Hybrid Wireless technology led to a quantum leap in transmission quality. Since 2018, the SRc series has integrated Dante networking capabilities for large multi-channel setups.
Practical Use in Film
Lectrosonics dominates Hollywood productions: "The Revenant" (2015) used over 30 channels for ensemble scenes in extreme weather conditions. In "Dunkirk" (2017), the waterproof transmitters enabled underwater shots. Bag systems (SRc/SRb) are integrated into boom poles, and bodypack transmitters (SMQV/LT) are hidden under costumes. Production Sound Mixers use up to 64 channels simultaneously via Dante networks. The SmartTune function significantly reduces frequency coordination during exterior shoots.
Comparison & Alternatives
Main competitors include Sennheiser (G4/EW-D series), Audio-Technica (System 10 PRO), and Shure (Axient Digital). Lectrosonics surpasses them in range and RF stability but costs 20-40% more. Sennheiser offers better menu navigation, while Audio-Technica provides more affordable entry-level models. For broadcast applications, Shure Axient competes with comparable channel efficiency. Zaxcom systems integrate recording functions, which Lectrosonics only began offering in 2019 (M2R). For low-budget productions, Røde Wireless GO or Deity Connect systems dominate the market.
