5.2 Recording Audio
Once the microphone and receiver are paired, open your device's camera or audio recording application. The system will automatically use the external microphone for audio input. Begin recording as usual.
5.3 Omnidirectional Sound Pickup and Noise Reduction
The KWM-1 features an omnidirectional microphone, capturing sound equally from all directions. Integrated DSP (Digital Signal Processing) technology actively reduces background noise, enhancing the clarity of your recordings.
