Description
The LARK M2S DUO is a compact dual-channel wireless microphone system designed to capture clear audio from two subjects simultaneously. It pairs two ultracompact transmitters that include built-in omnidirectional microphones with a USB-C plug-in receiver that connects directly to modern mobile devices. The system is supplied with a dedicated charging case to recharge the transmitters and receiver on the go.
Key features include interference-resistant 2.4 GHz digital audio transmission, a maximum line-of-sight range of 1000 ft, and support for 24-bit 48 kHz audio resolution. Each transmitter offers onboard controls including environmental noise cancellation toggling and an auto-level/gain function to simplify recording levels. Included windscreens help reduce wind noise for outdoor shoots.
Performance specifications deliver a 70 dB signal-to-noise ratio and a maximum SPL of 116 dB, with a frequency response spanning 20 Hz to 20 kHz. The transmitters use RF circuits optimized to resist interference in typical production environments and employ 2.4 GHz QPSK sync for stable links. The system uses non-diversity operation and supports up to two transmitters per band.
Connectivity is centered on the USB-C plug-in receiver which runs on bus power from the host device and offers LED indicators for transmitter status. The receiver provides a USB-C male connection and a USB-C female pass-through and is compatible with Android and iOS devices. System parameters such as volume and noise cancellation are adjustable from the LarkSound mobile app and firmware updates are supported via the app.
Typical applications include mobile journalism, run-and-gun video production, vlogging, interviews, and content creation where a low-profile, easy-to-deploy wireless audio solution is required. The small titanium clip-on transmitters are discreet on talent and their logo-free housings support a low-visibility setup. The included charging case extends field runtime for extended shoots.
Setup and daily operation are straightforward – pair the transmitters to the plug-in receiver, mount the transmitters on talent, and monitor levels via the LarkSound app or LED indicators. The internal transmitter batteries provide approximately nine hours per charge and the 680 mAh charging case extends total system runtime to roughly 30 hours. The metal housings and compact footprint make the system rugged and travel friendly for location work.
