3. Setup Instructions
Follow these steps to set up your microphone:
- Placement: Place the microphone on a stable, flat surface, such as your desk. Position it approximately 15-30 cm (6-12 inches) from your mouth for optimal voice capture.

- Right-click the speaker icon in the system tray and select "Sound settings" or "Recording devices".
- In the Sound window, navigate to the "Recording" tab.
- Locate the "Speedlink Pure Microphone" or a similar entry. If multiple microphones are listed, speak into your Speedlink microphone to identify the active one (look for the green level meter).
- Right-click on the Speedlink microphone and select "Set as Default Device".
- Double-click the microphone to open its properties. Go to the "Levels" tab and adjust the microphone volume to an appropriate level.
- Go to the "Listen" tab and check "Listen to this device" to test the microphone through your speakers/headphones (remember to uncheck it after testing to avoid feedback).
- Configure Audio Settings (macOS):
- Go to "System Preferences" > "Sound".
- Select the "Input" tab.
- Choose "External Microphone" or "Line In" as your input device.
- Adjust the input volume slider to your desired level.

4. Operating Instructions
Once connected and configured, your Speedlink Pure Desktop Voice Microphone is ready for use.
- Voice Communication: Use the microphone for online calls, voice chat, dictation, or recording. Ensure the application you are using is configured to use the Speedlink microphone as its input device.
- Optimal Speaking Distance: For clear audio, speak directly into the microphone from a distance of 15-30 cm (6-12 inches). Avoid speaking too close, which can cause distortion, or too far, which can result in low volume.
- Adjusting Position: The flexible gooseneck allows you to adjust the microphone's angle and height for comfortable and effective use.
- Software Volume Control: Adjust the input volume through your computer's sound settings or within the specific application you are using (e.g., communication software, recording software).

5. Maintenance
Proper care ensures the longevity of your microphone.
- Cleaning: Use a soft, dry cloth to wipe the microphone's surface. Do not use liquid cleaners or abrasive materials, as these can damage the device.
- Storage: When not in use, store the microphone in a clean, dry environment, away from extreme temperatures and direct sunlight.
- Handling: Avoid dropping the microphone or subjecting it to strong impacts. Do not forcefully bend the gooseneck beyond its natural range of motion.
6. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
- No Sound Output:
- Ensure the microphone's 3.5mm jack is fully inserted into the correct microphone input port on your computer.
- Verify that the microphone is selected as the default recording device in your computer's sound settings (refer to Section 3).
- Check the microphone input volume levels in your computer's sound settings and any application you are using.
- Test the microphone on another computer to rule out a computer-specific issue.
- Poor Sound Quality (Low Volume, Distortion, Static):
- Adjust the microphone's position and distance from your mouth (15-30 cm is ideal).
- Check and adjust the input volume levels in your computer's sound settings. If the volume is too high, it can cause distortion.
- Ensure there are no obstructions between your mouth and the microphone.
- Minimize background noise in your environment.
- Ensure the 3.5mm jack is clean and free of debris.
- Microphone Not Detected:
- Try connecting the microphone to a different 3.5mm input port if available, or to another computer.
