Polar Pattern

Image: Hypercardioid Polar Pattern (Heart at 1KHz). This pattern is effective at isolating the sound source from unwanted background noise.

4. Setup

1. Attach Shock Mount: Secure the BM-700 microphone into the provided plastic shockproof frame. Ensure it is firmly seated to minimize vibrations.
2. Mount Microphone: Attach the shock mount assembly to a compatible microphone stand. The shock mount is designed to fit standard microphone stands.
3. Connect Audio Cable:
   • Connect the XLR (three-pin) end of the audio cable to the bottom of the BM-700 microphone.
   • Connect the 3.5mm jack end of the audio cable to your computer's microphone input port (usually pink or labeled with a microphone icon).

   Note: This microphone is designed to work with 5V plug-in power provided by standard computer microphone inputs. It does not require 48V phantom power.

   • On your computer, navigate to your sound settings (e.g., Windows: Control Panel > Sound > Recording; macOS: System Preferences > Sound > Input).
   • Select the connected microphone as your default recording device.
   • Adjust the input level (gain) to an appropriate level. Start low and increase as needed to avoid clipping.

5. Operating Instructions

1. Positioning: Due to its hypercardioid polar pattern, the BM-700 is most sensitive to sounds directly in front of it and rejects sounds from the sides and rear. Position the microphone directly towards the sound source (e.g., your mouth for vocals, instrument for recording) for optimal sound capture and to minimize background noise.
2. Monitoring: Use headphones to monitor your audio input while recording or streaming to ensure proper levels and sound quality.
3. Software Usage: Open your preferred audio recording software, live streaming application, or communication platform. Select the BM-700 as your input device within the application's settings.
4. Adjusting Levels: Fine-tune the microphone's input level in your software to achieve clear audio without distortion.

6. Maintenance

• Cleaning: Gently wipe the microphone body with a soft, dry cloth. Do not use liquid cleaners or solvents, as they may 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 or subjecting the microphone to strong impacts, as this can damage the internal components.
• Cable Care: Do not bend or crimp the audio cable excessively. Store it neatly to prevent tangling and damage.

7. Troubleshooting

No Sound Output:

• Ensure the audio cable is securely connected to both the microphone and your computer's microphone input.
• Verify that the BM-700 is selected as the input device in your computer's sound settings and your recording/streaming software.
• Check the input volume levels on your computer and software; they might be muted or set too low.
• Confirm your computer's 3.5mm microphone input provides 5V plug-in power. Some older or specialized sound cards might require specific drivers or settings.

Poor Sound Quality / Distortion:

• Adjust the input gain. If the level is too high, it can cause distortion (clipping). If too low, the sound will be faint and noisy.
• Ensure the microphone is positioned correctly, facing the sound source directly, and not too far away.
• Check for environmental noise. The hypercardioid pattern helps, but a quiet recording environment is always best.
• Inspect the audio cable for any damage or loose connections.

Microphone Not Recognized by Computer:

• Try connecting the microphone to a different 3.5mm input port or another computer to rule out port issues.
• Ensure your computer's audio drivers are up to date.

8. User Tips

• Optimal Placement: For vocals, position the microphone 6-12 inches (15-30 cm) from your mouth. Experiment with distance to find the sweet spot for your voice and room acoustics.
• Pop Filter: While not included, using an external pop filter can significantly reduce plosive sounds (like 'p' and 'b') and protect the microphone capsule from moisture, improving overall sound clarity.
• Room Acoustics: Even with a hypercardioid microphone, recording in a room with good acoustics (e.g., minimal echo, soft furnishings) will yield better results.
• Reliability: To ensure reliable performance, always handle the microphone and its components with care and store them properly when not in use. Regular checks of cable connections can prevent intermittent issues.
