4. Operating Instructions
- Volume Control: The microphone features a volume knob on its body. Rotate the knob clockwise to increase the input volume and counter-clockwise to decrease it.
- Optimal Placement (Cardioid Pattern): The K669 utilizes a cardioid polar pattern, meaning it primarily picks up sound from the front. For best results, position the microphone directly in front of the sound source (e.g., your mouth) within a 30cm range. This helps to minimize background noise and capture clear audio.
