Hollyland Lark M3 Combo 4TX&2RX USB-C and Camera RX and 4 x Wireless Microphone

The Hollyland LARK M3 Combo 4TX & 2RX is a wireless microphone system that supports up to four transmitters and two receivers simultaneously. It provides 48 kHz, 32-bit float audio output, three-level AI noise cancellation and independent four-channel recording. Each transmitter weighs 9 g and attaches magnetically. Designed for multi-person interviews, panel discussions and multi-camera filming, the system offers a transmission range of up to 300 m. Each transmitter runs for up to 8 hours on a charge, with up to 24 hours of use when recharged using the included charging case.

Key features

• Four transmitters and two receivers: Record up to four speakers simultaneously using one Camera RX and one USB-C RX.
• 48 kHz / 32-bit float audio: Maximum sound pressure level (SPL) of 125 dB and signal-to-noise ratio (SNR) of ≥ 70 dB help prevent clipping and provide a wide dynamic range. 32-bit float output is supported with third-party recording apps on Apple iOS and macOS; Android supports up to 24-bit audio.
• Four independent recording tracks: Output four isolated audio tracks to a computer via USB-C or to a camera using an optional hot-shoe adapter.
• Three-level AI noise cancellation: Reduces continuous and transient noise, with selectable levels of 10 dB, 15 dB and 20 dB.
• Voice optimisation and custom settings: Includes one-touch de-essing and eight built-in voice presets, adjustable in the Hollyland LarkSound app. Each transmitter supports one independent setting at a time.
• Compact 9 g transmitters: Button-sized design measuring 26.5 mm in diameter and 10 mm thick, with magnetic attachment.
• Transmission range up to 300 m: Uses 2.4 GHz adaptive frequency hopping (AFH) and proprietary HDT wireless technology.
• Smart role assignment: Automatically assigns a primary receiver for adjusting settings such as noise cancellation, mute and gain, and a secondary receiver for monitoring. Roles switch automatically if the primary receiver loses its connection.
• Battery life and secure-lock charging case: Transmitters run for up to 8 hours per charge. The 1,800 mAh charging case provides more than two full charges for all four transmitters.
