Components:
- Microphone Capsule: Large gold-sputtered diaphragm.
- -10dB Pad Switch: Reduces input sensitivity by 10dB for loud sound sources.
- Low-Cut Filter Switch: Engages a low-frequency roll-off to reduce rumble and unwanted bass.
- XLR Connector: Standard 3-pin XLR output for connecting to audio interfaces or mixers.
- Shockmount: Isolates the microphone from vibrations and handling noise.
- Pop Filter: Reduces plosive sounds (P, B) and protects the microphone capsule.
4. Setup
Follow these steps to set up your BOYA BY-M800 microphone for recording.
- Attach the Shockmount: Secure the BY-M800 microphone into the included shockmount. Ensure it is firmly seated to prevent accidental dislodging.
- Mount to a Stand: Attach the shockmount to a microphone stand using the standard 3/8" or 5/8" thread adapter. Tighten securely.
- Position the Pop Filter: Attach the pop filter to the microphone stand and position it approximately 1-2 inches in front of the microphone capsule. This helps to reduce plosive sounds and protect the diaphragm.

- Connect the XLR Cable: Connect one end of the supplied 3m (10ft) XLR cable to the XLR output on the bottom of the microphone. Connect the other end to an audio interface, mixer, or preamplifier that provides 24V or 48V phantom power.

Figure 4.2: Illustration of the BY-M800 microphone connected via its XLR cable, emphasizing the requirement for 24V or 48V phantom power from the connected device.
- Activate Phantom Power: Ensure phantom power is enabled on your audio interface or mixer. The BY-M800 requires phantom power to operate.
- Adjust Switches (if needed):
- If recording very loud sound sources (e.g., drums, loud vocals), engage the -10dB pad switch to prevent distortion.
- If experiencing low-frequency rumble or unwanted bass noise (e.g., air conditioning, traffic), engage the low-cut filter switch.
5. Operating the Microphone
Once set up, the BY-M800 is ready for use. Here are some tips for optimal performance.
Microphone Placement:
- Vocals: For vocal recording, position the microphone 6-12 inches from the vocalist, directly facing the sound source. Always use the pop filter.
- Instruments: Placement will vary depending on the instrument. Experiment with distance and angle to capture the desired tone. The cardioid pattern is most sensitive directly in front of the microphone.

Monitoring and Gain Staging:
- Monitor your audio through headphones connected to your audio interface to hear the microphone's output.
- Adjust the gain (input level) on your audio interface or mixer so that the signal is strong but does not clip or distort. Aim for peak levels around -6dB to -3dB on your recording software's meters.
6. Maintenance
Proper care will extend the life and performance of your BY-M800 microphone.
- Cleaning: Use a soft, dry cloth to wipe down the microphone body. Do not use liquid cleaners or solvents, as they can damage the microphone.
- Storage: When not in use, store the microphone in a dry, dust-free environment, preferably in its original packaging or a protective case.
- Handling: Avoid dropping the microphone or subjecting it to strong impacts, as this can damage the delicate internal components.
- Moisture: Keep the microphone away from moisture and extreme temperatures.
