Hollyland LARK M3 Combo 4TX+2RX Wireless Microphone (Space Grey)

Four voices across two receivers

The four transmitters send each speaker’s voice to the included USB-C and Camera Receivers, so four people can wear individual microphones while the same audio reaches two recording devices at once. The USB-C Receiver plugs directly into compatible mobile devices for digital audio, while the Camera Receiver connects to cameras through its 3.5mm output or sends digital audio over USB-C. When either receiver connects to a computer via USB-C and compatible recording software, all four transmitters can be captured as isolated audio tracks, letting you adjust each speaker’s level separately during editing.

More headroom for changing voices

The LARK M3 outputs audio at up to 48kHz/32-bit float when the connected device and recording application support it. That format gives compatible software more room to accommodate large changes between quieter speech and stronger peaks during recording and post-production. The microphones handle up to 125dB SPL, while the signal-to-noise ratio of at least 70dB keeps speech separated from the system noise floor. Auto-Limit Clip Protection also manages sudden level jumps, automatically reducing excessive peaks before they overload the recording level. Android currently outputs up to 24-bit, while Apple devices require compatible third-party recording software for 32-bit float.

Noise reduction for four speakers

AI Noise Cancellation offers three strengths: 10dB, 15dB, and 20dB. A stronger level reduces background sounds such as traffic, wind, running water or air-conditioning, while a lighter setting applies less processing when the surroundings are quieter. You can switch Noise Cancellation on or off from the transmitters or receivers, while individual voice profiles in HollyAudio let each of the four speakers use processing suited to their own voice.

Separate control for each receiver

When both receivers operate together, the LARK M3 assigns one as the Primary Receiver and the other as Secondary. The Primary Receiver changes shared transmitter settings such as mute and Noise Cancellation, preventing conflicting adjustments from two recording positions, while each receiver keeps its own output and channel settings. The USB-C Receiver offers six gain levels through the HollyAudio app, while the Camera Receiver provides three gain levels through its physical slider or the app. If the Primary Receiver goes offline, the other connected receiver can take over.

Eight-hour battery and flexible connections

Each transmitter runs for approximately eight hours, providing enough operating time for interviews, presentations and longer recording sessions without frequent charging. In open, unobstructed conditions, the 2.4GHz wireless link reaches up to 300m, while adaptive frequency hopping shifts between available frequencies as radio conditions change. The USB-C Receiver includes a second USB-C port for powering a connected phone during recording, while the Camera Receiver provides a dedicated 3.5mm analogue audio output for camera connection.
