8. User Tips
- Check Input Type: Always ensure you are plugging the receiver into a "MIC IN" port on your audio device. Using "LINE IN" or "AUX IN" ports will not work correctly and may result in no sound or poor audio quality.
- Adapter for Smaller Jacks: If your audio equipment has a 3.5mm (1/8 inch) microphone input, you will need a 6.35mm to 3.5mm adapter. Make sure this adapter is specifically for microphone inputs.
- Single Receiver for Both Mics: The system is designed for both microphones to connect to a single receiver. You do not need a separate receiver for each microphone.
- Optimal Placement: For the best wireless performance, try to keep the receiver in a central location, free from obstructions, and within the recommended 30-meter range.
- Battery Management: Keep an eye on the battery indicators on both the microphones and the receiver. Fully charging before an event and recharging promptly after use will ensure consistent performance.
