Observação: Additional cables or accessories may be required depending on your audio setup and are sold separately.
3. Configuração
- Colocação: Position the microphone on a flat, hard surface such as a table, floor, or wall. The surface acts as a "boundary" to enhance direct sound pickup and minimize reflections, improving clarity.
- Conexão: Connect the microphone's output cable (typically a 3.5mm or XLR connector, depending on the specific model variant and included cable) to the input of your audio mixer, amplifier, or recording device. Ensure the connection is secure.
- Poder: This microphone typically operates on phantom power (if XLR) or battery power (if 3.5mm and designed for portable devices). Refer to your specific microphone's cable and connector type to determine power requirements. Ensure your audio device provides the necessary power.
- Nível de entrada: Set the input level on your audio device to a low setting initially.
4. Instruções de operação
- Ligar: Turn on your audio mixer, amplifier, or recording device.
- Ajustar nível de entrada: Gradually increase the input level on your audio device while speaking or making sound near the microphone. Adjust until the audio level is strong but does not clip or distort.
- Som do monitor: Use headphones or monitor speakers connected to your audio device to listen to the microphone's output. This helps in fine-tuning placement and gain settings.
- Posicionamento ideal: For best results, place the microphone as close as possible to the sound source without being obtrusive. For group discussions, a central placement on a table is often effective.
- Captação Omnidirecional: The omnidirectional pattern means the microphone picks up sound equally from all directions. This is beneficial for capturing ambient sound or multiple speakers around the microphone.
5. Manutenção

- Armazenar: When not in use, store the microphone in a cool, dry place, away from direct sunlight and extreme temperatures.
- Manuseio: Avoid dropping or subjecting the microphone to strong impacts, as this can damage the internal capsule.
