Lectrosonics launches L1 Sub-Miniature Lavalier

Born from a collaboration with the Freedman Group, the new Lectrosonics L1 Sub-Miniature Lavalier Microphone features Sonaura capsule technology.

The Sonaura capsule is a result of a five-year, $10 million research investment. The studio-grade Micro-Electro-Mechanical System’s (MEMS) silicon technology replaces traditional FET-based designs with a patented encapsulated diaphragm.

Unlike traditional capsules, which can vary between batches, the L1’s silicon fabrication ensures precision. Every L1 unit is matched in both sensitivity and frequency response to within 0.5dB, to offer production mixers and sound designers repeatability across multiple talent microphones.

The L1 has an ultra-low noise floor, with an EIN of just 11dB(A), and offers an 83dB signal-to-noise ratio for clear voice and instrument capture. Additionally, the L1 is designed for a natural sound that can be tailored via interchangeable acoustic caps for either flat or elevated high-frequency response. As well as this, when the L1 is paired with the Lectrosonics DSSM transmitters, it features a switchable sensitivity mode, allowing it to handle up to 135dBA SPL.

The L1 is also impervious to moisture, as a result of a combination of the Sonaura capsule’s inherent properties, a specialised hydrophobic internal coating and hydrostatic pressure-sealing via 0.4mm laser-drilled cap ports. Additionally, when used with the IP57-rated Lectrosonics DSSM micro-transmitter, the entire assembly is waterproof.

The L1 maintains a 5.4mm diameter footprint, compatible with standard industry mounting accessories. It features a Kevlar-reinforced cable and an ID ring system at the connector for rapid on-set identification.

"The L1 is the culmination of the acoustic expertise of the Freedman Group, the cutting-edge manufacturing of Infineon, and Lectrosonics’ rich audio electronics heritage," said Karl Winkler, EVP of product and sales at Lectrosonics. "By leveraging MEMS technology, we’ve moved beyond the physical limitations of traditional microphones to give our users a tool that is more consistent, more robust, and quieter than anything previously possible. And wait until you hear the sound – it is incredible!"

The Lectrosonics L1 is available in Q2 in black with a LEMO connector, with white, brown, and beige colours and 5-pin connector variants following later in 2026.
