3.1 Connecting the Microphone

Prepare the Microphone: Choose either the foam windscreen or the fur windshield based on your recording environment. The foam windscreen is suitable for indoor use, while the fur windshield is recommended for outdoor use to minimize wind noise. Gently slide the chosen windscreen over the microphone capsules.
Connect to Device: Insert the USB Type-C connector of the BY-DM100 microphone directly into the USB Type-C port of your Android smartphone or tablet. Ensure the connection is secure.
Device Recognition: Your Android device should automatically recognize the microphone. Some devices may display a notification indicating an external audio device is connected.

Once connected, the microphone is ready for use with most audio and video recording applications on your Android device. You may need to select the external microphone as the audio input source within your specific application settings.

4. Operating Instructions

4.1 Recording Audio

Open Recording Application: Launch your preferred audio or video recording application on your Android device.
Select Microphone Input: In some applications, you may need to navigate to the settings and select the external USB microphone as the audio input source. This step is often automatic but can vary by application.
Position the Microphone: For optimal stereo recording, position the microphone towards the sound source. The X/Y configuration of the capsules is designed to capture a natural stereo image.
Monitor Audio (if supported): If your device or application supports real-time audio monitoring through the USB-C port (e.g., with headphones connected to the device's headphone jack, if available, or through a USB-C hub with a headphone jack), monitor your audio levels to prevent clipping or distortion.
Start Recording: Begin your recording session.
