Flexible Wireless Audio for Multi-Person Productions
The Hollyland LARK M3 Combo 4TX&2RX is an ultracompact wireless microphone system designed for flexible interviews, multi-person shoots, and complex production setups. This kit includes four lightweight clip-on microphone/transmitters, a USB receiver, and a camera receiver. 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. 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.
When used with a hot shoe adapter, the LARK M3 camera-mount receiver supports four independent audio tracks for postproduction. Four isolated tracks can also be captured by connecting either the USB-C Receiver or Camera Receiver to a computer or mobile device via USB-C and using compatible recording software.
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, 3.5mm cable, 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
In multi-receiver configurations, the first connected receiver operates as the Primary Receiver, providing system control and real-time transmitter status monitoring, while Secondary Receivers monitor transmitter status without access to system adjustments. Gain can be adjusted across six levels on the USB-C Receiver through the app and three levels on the Camera Receiver using its onboard slider or the app.
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 4TX&2RX 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.
