Flexible Wireless Audio for Multi-Person Productions

The Hollyland LARK M3 Combo 2TX&4RX is an ultracompact wireless microphone system designed for flexible interviews, multi-person shoots, and complex production setups. This kit includes two lightweight clip-on microphone/transmitters and four USB-C receivers. The LARK M3 platform supports up to four transmitters and four receivers, with one receiver able to connect to as many as four transmitters and one transmitter able to pair with up to four receivers simultaneously. Transmitters and receivers can also be added or removed during a shoot without interrupting ongoing audio capture.

32-Bit Float Audio and AI Noise Cancellation

The LARK M3 delivers 48 kHz / 32-bit float recording on iOS devices and 24-bit recording on Android. A 70 dB signal-to-noise ratio and 125 dB maximum SPL help capture everything from quiet speech to powerful peaks. Hollyland's HDT wireless technology provides 50% faster transmission to carry more audio data, while AI noise cancellation uses deep learning and computational auditory scene analysis to suppress transient and continuous background sounds. Three adjustable noise cancellation levels (10, 15, and 20 dB) allow performance to be tailored to the recording environment.

Custom Voice Tuning and Independent Tracks

Auto-Limit Clip Protection intelligently balances excessive volume levels to help maintain stable, clear audio. In addition, built-in voice processing includes one-tap vocal enhancement with de-essing, plus eight vocal presets for different voices and recording situations. Presets can be fine-tuned in the app and compared with the original audio, and each transmitter can use its own independent preset. The receiver's 4-Track mode allows you to record up to four independent audio tracks, as long as your computer or mobile software supports 4-track recording. The receiver also features Mono and Stereo modes for simpler recording setups.

Compact Design with Long-Range Operation

Each transmitter weighs only 9g and uses a button-size design for discreet placement without pulling or deforming clothing. Clip-on and magnetic mounting provides flexible positioning, while the included charging and storage case accommodates transmitters, receivers, and furry windshields; it also features a safety-lock mechanism. The system operates worldwide in the 2.4 GHz frequency spectrum, providing a transmission range of up to 1000' in open, unobstructed environments without interference; it also incorporates an RF-interference-resistant circuit for use in signal-dense environments.

Monitoring, Control, and Extended Runtime

Transmitters can be muted individually from their onboard buttons, while the app can mute individual or all transmitters. Triple-pressing a transmitter button starts recording, and indicator lights can be controlled from the app. Internal rechargeable batteries power the camera-mount receiver for 8 hours and the transmitters for 9 hours, while the 2TX&4RX charging case supplies up to two full recharges. The system also supports continuous USB-C-powered operation, Apple MFi certification for iOS devices, and playback without unplugging
