FIFINE K025 Wireless Microphone System User Manual

1. Introduction

The FIFINE K025 Wireless Microphone System is designed to provide clear, transparent audio for various applications, including karaoke nights, house parties, and public address systems. Its UHF wireless capability ensures a strong, clear signal with 20 selectable frequencies, minimizing interference and dropouts for reliable performance over a range of over 80 feet.

This handheld dynamic microphone features a cardioid polar pattern, which picks up your voice with a warm, smooth sound and offers excellent feedback rejection. It is engineered for maximum gain before feedback and ensures your voice cuts through any mix, providing low handling noise sensitivity and brilliant sound quality.

The system offers a high level of convenience and flexibility, allowing for unimpeded movement and portability without loss of sound quality. It is a plug-and-play solution for easy setup, featuring on/off switches and low-battery warning indicators on both the receiver and microphone for constant monitoring of system operation.

3.2 Connecting the Receiver

The receiver unit features a 1/4" (6.35mm) jack output. It is designed to connect directly to a powered speaker, PA system, or amplifier with a compatible MIC input. The receiver is not compatible with 3.5mm earphone jacks, phones, computers, cameras, tablets, or Apple products.

Figure 3.2: The receiver connects directly into a 1/4" (6.35mm) MIC input on a powered speaker or amplifier. It is not compatible with 3.5mm audio jacks.

Important Compatibility Note:

• Only compatible with speakers with MIC input.
• Not recommended for use with portable Bluetooth speakers lower than 15 watts (e.g., JBL Charge, Doss Touch, Bose).
• Not compatible with phones, computers, cameras, tablets, APPLE products, and all line-in/aux-in JACKS.

4. Operating Instructions

4.1 Powering On and Off

To power on the microphone, slide the ON/OFF switch located on the microphone body to the "ON" position. Similarly, slide the ON/OFF switch on the receiver to the "ON" position. A green light on the receiver will indicate it is powered on and ready.

4.2 Frequency Selection

The FIFINE K025 system offers 20 selectable UHF frequencies to prevent interference and ensure clear performance. To change the frequency, locate the small button inside the battery compartment of the microphone. Press this button to cycle through the available frequencies.

4.3 Optimal Usage

• Range: The system operates effectively over a range of over 80 feet, providing freedom of movement.
• Polar Pattern: The cardioid capsule is designed to pick up sound primarily from the front, reducing background noise and feedback. For best results, speak directly into the top of the microphone.
• Multiple Microphones: This system allows multiple wireless microphones to be used simultaneously, provided they are set to different frequencies.

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the microphone and receiver. Avoid using harsh chemicals or abrasive materials.
• Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Battery Care: Remove batteries from both the microphone and receiver if the system will not be used for an extended period to prevent leakage and damage.
• Anti-roll Ring: The included rubber anti-roll ring can be placed on the microphone to prevent it from rolling off surfaces.

Figure 5.1: The anti-roll ring can be easily slid onto the microphone body to provide stability and prevent rolling.

6. Troubleshooting

• No Sound Output:
  • Ensure both the microphone and receiver are powered on and have fresh batteries.
  • Verify the receiver is correctly plugged into a powered speaker or PA system's 1/4" MIC input, not a line-in/aux-in jack.
  • Check the volume levels on your speaker/PA system.
  • Try changing the frequency on the microphone to avoid interference (refer to Section 4.2).
• Interference/Poor Sound Quality:
  • Change the operating frequency on the microphone.
  • Ensure there are no major obstructions between the microphone and the receiver.
  • Keep the receiver away from other electronic devices that might cause interference.
• Microphone Not Turning On After Battery Change:
  • Ensure batteries are inserted with correct polarity.
  • If the issue persists, restore the mic to factory settings by following the user manual's specific instructions for factory reset (if available).
• Limited Range:
  • Ensure the receiver's antenna is fully extended.
  • Minimize physical obstructions between the microphone and receiver.
  • Check battery levels in both units.
