This document provides a comprehensive FAQ for the Lark M1, a device designed to enhance audio recording, particularly with smartphones and cameras. It addresses common issues users might encounter and offers solutions, covering connectivity, audio quality, and compatibility across various devices.

Function Description

The Lark M1 is primarily an external microphone system intended to improve audio recording quality compared to built-in device microphones. It is designed to work with a range of devices, including iPhones, Android smartphones, and cameras (Sony, Canon, Fuji). The system aims to provide clear audio by addressing issues such as background noise, low or high recording volume, and compatibility challenges. It utilizes various adapters and cables to ensure proper connection and optimal performance, depending on the host device's port configuration. For computer connectivity, it functions as an audio input device, typically requiring a USB sound card for live streaming or recording.

Usage Features

Smartphone Connectivity and Audio Quality:

iPhone Connectivity: To record with an iPhone, the Lark M1 requires an MFi (Made for iPhone/iPod/iPad) certified Lightning to 3.5mm adapter. Non-MFi certified adapters will not allow recording. Users are advised to purchase such cables from the official Apple store to ensure compatibility and functionality.
Android Smartphone Connectivity (General):
- Recording Issues: If an Android smartphone cannot record, users should check the sound settings. Navigate to "Settings" > "Sound and Vibration" > "More Sound Settings" > "Default Recording Device" and select "external device."
- No "Default Recording Device" Option: If this setting is unavailable, some native camera apps on Android smartphones may not support external microphones. In such cases, users should use third-party camera apps like TikTok or SnackVideo.
- Loud Background Noise: To mitigate loud background noise when connecting via a Type-C to 3.5mm adapter, it is crucial to use an adapter with a DAC (Digital-to-Analog Converter) and Hi-Res audio support. This ensures better audio processing and reduces unwanted noise.
Samsung Smartphone Connectivity:
- With 3.5mm Headphone Port and Type-C: For Samsung phones with both ports, use a 3.5mm TRS to 3.5mm TRRS Patch Adapter Cable to connect to the Lark M1.
- Type-C Only: If the Samsung phone only has a Type-C port, users must use official Type-C adapter accessories. Using unofficial adapters may result in an "Unsupported Accessory" prompt and prevent recording.
Low Recording Volume:
- Receiver Adjustment: The recording volume can be adjusted from the receiver. Pressing the "+" button three times will set the volume to maximum. The Lark M1 has three volume levels, with medium being the default.
- Microphone Distance: Adjusting the distance between the microphone and the mouth can also control volume. Closer proximity results in louder audio, while farther distance results in lower audio.
High Recording Volume:
- Microphone Placement: To avoid overexposed and distorted recordings, do not hold the microphone too close to the mouth. This also prevents saliva from damaging the microphone. It is recommended to clip the microphone to the neckline, slightly close to the mouth.
Occasional Low Recording Volume (iPhone 12 Pro and other smartphones): Some smartphones, including the iPhone 12 Pro, employ automatic gain control (AGC), which can automatically reduce recording volume if the sound is too loud. To address this, press the "-" button on the receiver (RX) to reduce the volume, or place the transmitter (TX) slightly away from the mouth.

Camera Connectivity and Audio Quality:

Loud Background Noise with Cameras: When connecting the Lark M1 to Sony, Canon, or Fuji cameras, users need to set the camera's recording volume to the minimum to prevent loud background noise.
- Sony: Set recording volume to 1.
- Canon: Set to the first grid.
- Fuji: Set to -27dB.

Computer Connectivity for Live Streaming:

Connecting to a Computer: To connect the Lark M1 to a computer for live streaming, a USB sound card is required. Do not connect directly using a 3.5mm audio cable, as this requires complicated computer settings. After connecting via a USB sound card, select "USB sound card" as the recording input.

Cable and Adapter Selection:

The document provides a detailed guide for selecting the correct cable or adapter based on the smartphone's port configuration:

Android Phones with 3.5mm Headphone Port and Type-C: Use a 3.5mm TRS to 3.5mm TRRS Patch Adapter Cable.
Android Phones with Type-C Only:
1. Use a Type-C to 3.5 adapter with a DAC/Hi-Res.
2. Alternatively, use a 3.5mm TRS to 3.5mm TRRS Patch Adapter Cable.
iPhone:
1. Use an Apple Lightning to 3.5mm Headphone Jack Adapter from the official Apple store.
2. Alternatively, use a 3.5mm TRS to 3.5mm TRRS Patch Adapter Cable.

Maintenance Features

Microphone Film: For first-time use, there is a protective film on top of the microphone that needs to be removed to ensure optimal performance.
Preventing Damage: Avoid holding the microphone too close to the mouth to prevent saliva from spraying into and damaging the microphone.
