3. System Audio Settings
After connecting, you may need to select the FIFINE K683A as your default input device in your operating system's sound settings or within your recording/streaming software.

Operating Instructions
1. Cardioid Pickup Pattern
The K683A microphone utilizes a cardioid pickup pattern, meaning it primarily captures sound from the front while rejecting sound from the sides and rear. For optimal sound quality, always speak directly into the side of the microphone that features the 'FIFINE' logo.

2. Gain Control Knob
The gain knob on the microphone allows you to adjust the input sensitivity. Rotate the knob clockwise to increase sensitivity (make the microphone pick up quieter sounds) and counter-clockwise to decrease sensitivity (reduce background noise or prevent distortion from loud sources).
3. Mute Button
Press the mute button to instantly mute or unmute the microphone. The LED indicator will change color to show the microphone's status (e.g., green for active, red for muted).

4. Headphone Monitoring Jack
The 3.5mm headphone jack located on the back of the microphone allows for real-time audio monitoring. Connect your headphones to this jack to hear your own voice as captured by the microphone, or to monitor your computer's audio output, depending on your system settings and software.
