Hollyland LARK M3 Combo 2TX+4RX Wireless Microphone (Space Grey)
The Hollyland LARK M3 Combo 2TX+4RX is a compact 2.4GHz wireless microphone kit with two 9g transmitters and four USB-C receivers, capturing 48kHz/32-bit float audio on compatible devices and apps. Each transmitter mounts magnetically to clothing, while three-level AI noise cancellation reduces changing background sound. With four receivers included, the kit suits two-person interviews, presentations and productions that need the same audio sent to multiple USB-C devices.

FAQs:
Can both transmitters be used with all four receivers at the same time?
Yes. Both included transmitters can send audio to all four USB-C receivers simultaneously, so you can record two speakers across several devices without wearing multiple microphones. Each receiver gets the same transmitter feeds while maintaining its own output settings. This makes the kit useful when the same conversation needs to reach several phones, tablets or computers at once.
Why would I use four USB-C receivers?
Four receivers let the same two microphones feed several compatible USB-C recording devices at the same time. For example, separate operators can record the same speakers on different phones or computers without setting up another wireless microphone system for each device. Each receiver can have its own gain level, so the output can be adjusted to suit the connected recorder. Shared transmitter settings remain managed through the Primary Receiver.
Does the LARK M3 record in 32-bit float?
The LARK M3 can output audio at 48kHz/32-bit float, which gives the recording system more headroom when voices move between quieter speech and louder peaks. To actually record in 32-bit float, the connected device and recording app must support that format. On Apple devices, this means using a third-party app that supports 32-bit float, as the built-in Camera and Voice Memos apps record the LARK M3 signal at up to 24-bit. Android devices currently support up to 24-bit output.
How does the AI Noise Cancellation work?
Three selectable levels apply 10dB, 15dB, or 20dB of noise reduction. Higher settings apply stronger processing to sounds such as wind, traffic, running water and air-conditioning around the speaker. You can switch Noise Cancellation on or off from either transmitter or a USB-C receiver. This lets you match the amount of processing to the surrounding noise rather than running maximum reduction all the time.
Can I charge connected phones while the receivers are in use?
Yes. Each USB-C receiver has a separate USB-C port for charging the connected phone while its male USB-C connector remains plugged into the device. Powering through that port lets the phone stay connected to external power while recording. This is especially useful when several phones are recording for long periods and battery life would otherwise limit the session.
Can I add more transmitters later?
Yes. The LARK M3 system supports up to four transmitters and four receivers in total, so this kit already reaches the maximum receiver count but can still accept up to two additional transmitters. Adding more transmitters gives additional speakers their own microphones while retaining the four included USB-C receivers. The system can therefore grow from a two-person setup to up to four transmitters feeding the four receivers.
