Operating Instructions
1. Basic Recording
- Once the microphones and receiver are paired (solid green light), open your device's camera app, voice recorder, or any application that supports external audio input.
- Start recording. The microphone system will automatically capture audio.
- The system supports simultaneous audio capture from both microphones, ideal for interviews or dual-speaker content.

2. Noise Reduction
- The A3d features a built-in noise reduction chip with 3 levels of noise reduction.
- To cycle through noise reduction levels, briefly press the power button on the microphone while it is on. Each press will change the level, indicated by a subtle change in the indicator light's behavior (e.g., different blink patterns or color changes, refer to specific product documentation for exact indicators).
- This feature helps to filter out ambient noise, ensuring clear voice capture even in noisy environments.
