Lectrosonics L1-BK-LMO-DS-N

Lectrosonics L1-BK-LMO-DS-N Sonaura Lavalier Naked

The Lectrosonics L1-BK-LMO-DS-N is a black omnidirectional sub-miniature lavalier microphone with a Sonaura MEMS capsule and a Lemo connector for the Lectrosonics DSSM. The Naked version includes the microphone with its standard cap and an additional High Boost cap, supplied in a small cardboard box. A lapel clip, windscreen and storage box are not included.

This version is compatible exclusively with the Lectrosonics DSSM. It does not work with the SSM or with other Lemo-terminated transmitters.

The Sonaura capsule uses MEMS technology: silicon-based micro-electro-mechanical structures with an encapsulated diaphragm. Lectrosonics specifies unit-to-unit matching within 0.5 dB for sensitivity and frequency response. This limits differences between individual microphones when several L1 units are used within the same production.

The L1 has a self-noise level of 11 dB(A), a signal-to-noise ratio greater than 83 dB and a frequency response from 20 Hz to 20 kHz. High and low sensitivity can be selected through the DSSM, allowing the same microphone to accommodate different sound levels. The specified maximum sound pressure level is 135 dB SPL peak.

Both acoustic caps are included with this Naked version. The standard cap provides a 3 dB boost between 8 and 20 kHz. The High Boost cap provides a 9 dB boost between 12 and 14 kHz. This allows the high-frequency response to be adjusted without changing the microphone.

The watertight construction combines the properties of the MEMS capsule with a hydrophobic internal coating and 0.4 mm laser-drilled cap ports. According to Lectrosonics, the microphone remains functional when fully submerged. The microphone has a 5.4 mm diameter and a flexible Kevlar-reinforced cable. Identification rings at the connector help distinguish individual microphones.

Expected delivery: fourth quarter of 2026, according to the manufacturer. This is an estimated schedule, not a confirmed delivery date.

Compatibility

Suitable for the Lectrosonics DSSM/E01-A1B1 and DSSM/E01-B1C1. The transmitter is sold separately.

In the DSSM InpCfg menu, select L1 Hsns for high sensitivity or L1 Lsns for low sensitivity. These settings were introduced with firmware 3.09 (SUPER) / 2.01 (FPGA).

Other Version

The same microphone is also available as the Lectrosonics L1-BK-LMO-DS-K Kit. Alongside both acoustic caps, that version includes a lapel clip with rotating clasp, a windscreen and a moulded storage box with a transparent lid.
