Expert Features

• True All-Device Combo Kit : The LARK M2 Combo Version includes 2 transmitters, Camera Receiver, USB-C Plug Receiver, and Lightning Plug Receiver, giving one kit direct compatibility with cameras, compatible Android/USB-C devices, iPhones with Lightning, computers, and other supported recording gear.
• Tiny 9g Transmitters : Each button-sized transmitter weighs only approximately 9g, keeping clothing sag and bulky on-camera appearance to an absolute minimum.
• 48kHz / 24-bit Hi-Fi Audio : Records at 48kHz / 24-bit, capturing significantly more vocal detail and dynamic information than basic voice-recording hardware.
• 70dB+ Signal-to-Noise Ratio : A >70dB SNR helps maintain a low noise floor and cleaner vocal reproduction for interviews, reels, podcasts, vlogs, and professional video work.
• 115dB SPL Handling : The microphones handle sound pressure levels up to 115dB SPL, providing useful headroom when recording louder voices or energetic environments.
• Environmental Noise Cancellation : Built-in ENC targets environmental noise while preserving voice clarity, with noise cancellation activated directly from the transmitter.
• 300m Wireless Range : Both receiver types support up to 300m / 1,000ft line-of-sight transmission. With obstacles, Hollyland rates the mobile receiver for up to 60m and the Camera Receiver for up to 40m.
• 40-Hour Combo Battery Life : The camera-style charging case included with the Combo package supports approximately 40 hours of total use, while each transmitter runs for around 10 hours per charge.
• Fast Charging Case : The Combo Version’s 1950mAh Camera Version Charging Case can recharge the complete TX/RX system more than three times and charges in under 2 hours.
• Camera Mono / Stereo Modes : The included Camera Receiver supports Mono and Stereo recording modes when its 3.5mm output is connected to a camera.
• Physical Gain Knob : The Camera Receiver gives you an intuitive volume-control knob with three LED indicators, so levels can be checked and adjusted without diving through menus.
• Magnetic + Necklace Wearing : Use the included magnetic mounting system or the LARK M2 necklace silicone cases for discreet, flexible placement on clothing.
• LarkSound App Control : Firmware updates, volume adjustment, noise-cancellation settings, and real-time audio status can be managed through the LarkSound app.
• Factory Pre-Paired : The system arrives pre-paired, reducing setup friction—take it from the charging case, connect the required receiver, and get recording.
• Dual Anti-Interference Design : A metallic mesh plus Hollyland’s wireless design helps resist 2.4GHz, infrared, and RF interference, while Adaptive Frequency Hopping supports connection stability.
