4. Operating Instructions
4.1. Controls and Features
The microphone features intuitive controls for optimal audio performance:
- Echo Control: Adjust the echo effect using the slide button. This allows for fine-tuning the reverberation to suit your recording environment or preference. The echo function can also be disabled.
- Volume Control: Adjust the microphone's sensitivity and output volume using the slide button. Sliding the volume button to the bottom will smoothly mute the microphone without any clicking sound.
- Mute Indicator: When the microphone is muted, the LED indicator will turn red, providing a clear visual cue.
- Active Noise Cancellation (ANC): The noise-canceling function is initially off. To activate, slide the "ANC" button upwards until the LED indicator turns green. This feature is ideal for reducing ambient noise in various recording environments.

4.2. Real-Time Monitoring
The microphone includes a 3.5mm headphone interface for direct, zero-latency monitoring of your audio. This allows you to hear your voice and device audio in real-time, ensuring optimal sound capture and preventing issues like audio clipping or excessive background noise during live broadcasts, recordings, or online calls.

4.3. Cardioid Polar Pattern
The ZealSound microphone utilizes a Cardioid polar pattern, which means it is most sensitive to sound coming from directly in front of it and less sensitive to sounds from the sides and rear. This focused pickup pattern helps to effectively reject unwanted off-axis noise, resulting in clear and intelligible vocals for various applications such as ASMR, gaming, streaming, podcasting, and video recording.

- Storage: When not in use, store the microphone and its accessories in a clean, dry place, away from extreme temperatures and humidity. The original packaging can be used for safe storage.
- Charging: The microphone contains a Lithium Polymer battery. It is recommended to charge the microphone for 2 hours before initial use. Do NOT use the microphone while it is charging.
