Lectrosonics L1 Lavalier Uses Rode Sonaura MEMS Capsule

Lectrosonics has introduced the L1, an omnidirectional subminiature lavalier microphone built around a Sonaura MEMS (Micro-Electro-Mechanical Systems) capsule. Instead of a conventional FET-based design, the Sonaura silicon technology uses a patented encapsulated diaphragm.

Consistency and water resistance

Every L1 is matched to within 0.5 dB in both sensitivity and frequency response, so that several microphones on different speakers sound the same. Lectrosonics presents this repeatability as a benefit for production mixers and sound designers who place mics on multiple people in a scene. Lectrosonics also designed the mic to keep working when fully submerged. Three elements make this possible: the properties of the Sonaura capsule, a hydrophobic coating inside the mic, and pressure sealing through 0.4mm laser-drilled ports in the cap.

Specifications

• Frequency response 20 Hz to 20 kHz
• Standard cap: +3 dB from 8 to 20 kHz; High Boost cap: +9 dB at 12 to 14 kHz
• Sensitivity -34 dBV, or -54 dBV in low-sensitivity mode
• Signal-to-noise ratio above 83 dB, self-noise 11 dB SPL (A-weighted)
• Maximum SPL 135 dB peak, operating voltage 4.0V

When used with Lectrosonics' DSSM digital micro transmitter, a single L1 can run in either high- or low-sensitivity mode, which is selected in the transmitter menu. According to Lectrosonics, the L1 raises the bar in the industry for performance, unit-to-unit consistency and resistance to harsh conditions.

The black LEMO version is available now, and a 5-pin version is due later. Prices range from $500 to $700 depending on the version and on whether it is bought alone or as a kit.
