- Attach Pop Filter: If desired, attach the multi-layers metal wind protector (pop filter) to the microphone to reduce plosive sounds.
- Connect to Device:
- Connect the USB Type-B end of the provided cable to the port at the bottom of the microphone.
- Connect the other end of the cable (USB Type-A or Type-C, using the adapter if necessary) to an available USB port on your computer (Windows/Mac) or PlayStation 4.
- The microphone is plug-and-play and does not require additional drivers for most operating systems.

Operating Instructions
- Adjust Microphone Gain: Use the 'MIC' knob on the microphone body to adjust the input sensitivity (gain). Turn clockwise to increase gain and counter-clockwise to decrease it.
- Mute/Unmute: Press the mute button located below the gain knob. The LED indicator will be green when the microphone is active and red when it is muted.
- Real-time Monitoring: Plug your headphones into the 3.5mm headphone jack on the microphone to monitor your audio input in real-time without any noticeable delay.
- System Settings: After connecting, ensure the FIFINE K683A is selected as the input (microphone) and output (headphone, if monitoring through the mic) device in your computer's sound settings or recording software.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the microphone body and stand. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the microphone in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Handling: Handle the microphone with care to prevent damage. Avoid dropping or subjecting it to strong impacts.
- Disassembly: Do not attempt to disassemble the microphone. Unauthorized disassembly will void the product warranty.
Troubleshooting
- No Sound/Microphone Not Detected:
- Ensure the USB cable is securely connected to both the microphone and your device.
- Verify that the FIFINE K683A is selected as the default input device in your operating system's sound settings and any recording software you are using.
- Try connecting to a different USB port or a different computer to rule out port or device issues.
- Noise Issues:
- Ensure the microphone is placed in a quiet environment.
- Adjust the microphone gain to an appropriate level; too high gain can pick up unwanted background noise.
- Use the provided pop filter to reduce plosive sounds and breath noise.
- If experiencing persistent noise, refer to the troubleshooting diagram below or contact support.
- Headphone Monitoring Issues:
- The K683A headphone jack monitoring function cannot be disabled. If you wish to listen to system sounds without real-time mic monitoring, plug your headphones directly into your computer's headphone jack and set your computer's built-in speaker as the default output device.
- The output volume of the microphone's headphone jack cannot be adjusted separately on the microphone itself. Adjust the output volume through your computer's sound settings or recording software.
- Mute Button Click Sound: When the microphone's sensitivity and volume are at maximum, a physical sound from the button press might be heard. However, there should be no characteristic electronic click noise from the microphone itself.
- Compatibility with Boom Arm Stand: The microphone's bottom port is for the USB cable only. To connect to a standard boom arm stand, you will need a 3/8” Female to 5/8” Male adapter for the mic mount.
- Phone Compatibility: While not officially recommended, the microphone may work with phones using a suitable genuine adapter (e.g., Apple adapter for iPhone).

User Tips
- For optimal sound pickup, maintain a distance of 15-30cm from the microphone and set the volume to around 70%.
- If you plan to use the microphone with a boom arm, remember that an additional 3/8” Female to 5/8” Male adapter will be required to mount it.
- When using the headphone jack for monitoring, adjust the monitoring volume through your computer's sound settings or recording software, as the microphone itself does not have a separate volume control for this output.
- While the microphone is primarily designed for computers, it may function with smartphones using a genuine, compatible adapter.
