2. Color-coded protection ring: avoid microphone rolling on the surface and help to
2. Color-coded protection ring: avoid microphone rolling on the surface and help to
distinguish different channels.
3. Sound head: the sound signal is converted into electronic signals. This product uses
a separate portfolio.
4. Microphone body: Metal or plastic material (Metal material presents better texture.
Plastic material is easy to use.) Chassis assembling with microphone unit and PCB
inside the body and battery case are one-piece molding.
inside the body and battery case are one-piece molding.
5. EVA pads: prevent battery loose.
6. Battery case: Insert batteries &ensure the correct polarity(2×AAA)
7. Power switch: Turn “ON” when using microphone; turn ”OFF” when not using
