Lectrosonics M150

The Lectrosonics M150 is part of the Digital Hybrid Wireless system, meaning it actually uses a proprietary analog FM signal combined with digital control data. This hybrid approach captures the natural sound quality of analog audio while utilizing digital encryption to prevent interference and noise. It ensures flawless, zero-latency audio transmission.

The M150 is built with a highly efficient circuitry design that allows it to run for up to 5.5 hours on a single pair of AA batteries. This is slightly improved over older blocks in the Lectrosonics lineup, offering a longer window for uninterrupted recording. For full-day shoots, sound mixers often carry a quick-swappable battery sled to minimize downtime.

Operating in the UHF frequency spectrum, the M150 is renowned for its incredible range and ability to punch through RF interference in crowded environments. It can easily transmit cleanly for over 100 feet, even indoors with heavy concrete walls. This robust RF performance is why Lectrosonics gear is the standard for professional Hollywood film sets.

Yes, while Lectrosonics sells the system with their own high-quality lavaliers, the transmitter is designed to accept any standard electret condenser microphone. You simply need to use the bias resistor wiring inside the 5-pin input jack, which can be configured by a technician. This flexibility allows sound mixers to use industry favorites like Sanken COS-11D or DPA 4060s.
