Hollyland LARK M3 Explained – One Transmitter, Up to Four Receivers, and 4-Track Audio

Most budget wireless kits are built around one assumption: one receiver, one camera. The Hollyland LARK M3 breaks that assumption, because a single transmitter can feed up to four receivers at the same time. On a multi-camera interview, that means every camera can record the same clean lav signal instead of scratch audio. Here is how the system divides control between receivers, where the four isolated tracks actually arrive, and where its limits are.

We have previously covered the LARK M2 and the more discreet LARK M2S, as well as the LARK MAX 2, which adds onboard recording and timecode. The M3 sits between those approaches. It keeps the 9g (0.32oz) transmitter size of the M2 while adding 32-bit float output and much more flexible multi-transmitter and multi-receiver routing.

The LARK M3 is a 2.4GHz system with a 9g (0.32oz) transmitter, 48kHz audio at 24-bit or 32-bit float, three levels of AI noise cancellation, and a rated range of up to 300m (1,000ft). It scales in both directions: one receiver accepts up to four transmitters, and one transmitter pairs with up to four receivers, in any combination up to 4TX and 4RX. Two receiver types are available: a 5.9g (0.21oz) USB-C receiver for phones, tablets, and computers, and a 20g (0.71oz) camera receiver with 3.5mm TRS output and a USB-C port.

One lav, several cameras

On a typical two-camera interview with a single wireless kit, the receiver goes on the A camera. The B camera records its onboard microphone as a reference, and the editor syncs the angles by waveform and uses the A-camera audio for the whole scene.

The LARK M3 removes that step. A second, third, or fourth receiver pairs to the same transmitter, so each camera records the lav signal directly. The same applies to mixed setups, which Hollyland confirms in its FAQ: camera receivers and USB-C receivers can work together in one system as long as the total is four receivers or fewer. A presenter can feed a cinema camera, a phone recording a vertical version, and a laptop running a live stream from one transmitter. Transmitters and receivers can also be added or removed during a shoot without interrupting audio on the units that stay connected.

Hollyland has followed a similar logic on the video side. The Pyro Ultra wireless video system supports an unlimited number of receivers, and the LARK M3 brings a smaller version of that one-to-many idea to entry-level audio.

How the primary and secondary receivers divide control

When more than one receiver is connected, the system assigns roles automatically. According to the manual, the first receiver that connects after the transmitter powers on becomes the primary receiver, and every receiver after it becomes a secondary. The primary receiver controls the transmitters: noise cancellation, mute, the indicator lights, voice tuning presets, and Smart Reverb.

Two settings stay independent on every receiver: output gain and channel mode. Each camera can therefore run its own level and channel configuration without changing the transmitter settings for the rest of the system.

If the primary receiver goes offline during a take, the system selects one of the remaining receivers as the new primary while audio on the secondary receivers continues.

The roles can be changed. In the app, a secondary receiver can be promoted to primary, or the crew can disconnect all receivers except the one that should take control, and then reconnect the others.

Where the four isolated tracks actually arrive

The headline feature of four independent tracks needs precise reading, because it depends on the connection.

According to Hollyland’s manual and FAQ, the LARK M3 can record up to four isolated tracks, but only through compatible digital connections. The camera receiver’s 3.5mm TRS output is limited to Mono or Stereo, so four separate tracks require the separately sold LARK M3 Hot Shoe Adapter or a USB-C connection to a computer with compatible recording software.

On phones, 4-Track mode depends on the app. Hollyland’s FAQ says compatible third-party recording apps on iOS can support it, while the native camera apps on iOS and Android do not. The same applies to 32-bit float: it requires compatible software, and Android devices are limited to 24-bit.

Practical configurations

The flexible transmitter and receiver arrangement is what makes the M3 different from a conventional two-person wireless kit.

For a two-person interview on two cameras, both cameras can receive the same two microphones directly. For a four-person panel, four transmitters can feed one receiver, with four isolated tracks available through a compatible digital connection. A single presenter can instead feed several receivers at once, allowing the same microphone to reach a camera, phone and computer simultaneously.

The system can therefore be built around either the number of people being recorded or the number of devices that need to receive the audio.

Current limitations

The LARK M3 transmitters do not have internal recording, and the system does not support timecode. A triple press of the transmitter button starts and stops recording on the connected device, not in the microphone. If the 2.4GHz link drops, no backup copy exists on the transmitter.

Multiple receivers reduce some of that risk because each camera or device holds its own received copy of the audio, but all copies still depend on the same wireless transmission.

Battery life is approximately eight hours per transmitter with noise cancellation off, and 4 to 4.5 hours with it on. The camera receiver runs for approximately nine hours, and receivers can run continuously on USB-C power. Hollyland rates the 300m (1,000ft) range for open environments without interference.

How it compares within the LARK lineup

The LARK M3 keeps the compact 9g (0.32oz) transmitter format of the LARK M2 while adding 32-bit float output, AI noise cancellation, support for up to four transmitters and four receivers, and four-track recording through compatible digital connections.

The LARK MAX 2 moves further toward professional production. Its transmitters add onboard 32-bit float recording and timecode, giving crews a backup copy and a more complete sync workflow.

The M3 therefore makes the most sense when the priority is a small microphone and flexible routing between several people, cameras, or recording devices. The MAX 2 remains the stronger option when internal backup recording and timecode are more important.

Price and availability

The LARK M3 is available now in four kits. The 2TX&1RX kit is priced at $99, the 2TX&2RX kit is $119, the 2TX&4RX kit is $179, and the 4TX&2RX kit costs $179. B&H also sells single components: a transmitter at $39, a USB-C receiver at $29, and a camera receiver at $39. The hot shoe adapter is sold separately.
