Setup

Charging the Devices

Before first use, fully charge both the microphone (transmitter) and the receiver.

  1. Connect the dual USB charging cable to a USB power source (e.g., computer USB port, USB wall adapter).
  2. Connect one micro USB end of the cable to the charging port on the transmitter and the other to the charging port on the receiver.
  3. The charging indicator light on both devices will illuminate during charging and turn off or change color when fully charged. A full charge takes approximately 2 hours and provides 6-8 hours of working time.

Attaching the Microphone

  1. Identify the appropriate position on your wind instrument (flute, piccolo, clarinet, etc.) to attach the microphone. The clip is designed for tubular instruments.
  2. Gently open the clip on the microphone transmitter and secure it firmly to the instrument. Ensure it is stable and non-slip to prevent scratches.
  3. Adjust the flexible arm of the microphone to position the microphone head optimally for sound capture, typically near the mouthpiece or sound holes, while avoiding direct airflow that could cause noise.

Connecting the Receiver

  1. Plug the receiver unit directly into the input jack of your PA system, amplifier, or speaker.
  2. If your audio equipment requires a 6.35mm (1/4 inch) input, attach the provided 3.5mm to 6.35mm adapter to the receiver's 3.5mm jack before plugging it into the equipment.

Operating Instructions

Powering On/Off

  • To power on the transmitter (microphone) and receiver, slide their respective power switches to the "ON" position.
  • To power off, slide the switches to the "OFF" position.

Automatic Pairing

The transmitter and receiver are designed to pair automatically upon power-on. A blue indicator light on the receiver will confirm a successful connection.

LED Digital Screen Functions

The transmitter features an LED digital screen that displays key operational information:

  • Frequency (e.g., "C05"): Indicates the current UHF frequency channel. The system supports up to 40 sets working simultaneously without interference.
  • Battery Status: Shows the remaining battery power. Recharge when the indicator is low.
  • Volume (e.g., "U08"): Displays the current volume level.

Adjusting Settings

Use the "+" and "-" buttons on the transmitter to adjust the volume or change the frequency if interference occurs. Refer to the LED screen for current settings.

Usage Tips

  • For optimal sound quality, ensure the microphone is positioned correctly to capture the instrument's sound without picking up excessive key noise or breath sounds.
  • Maintain a clear line of sight between the transmitter and receiver for the best wireless performance, especially at longer distances.
  • This system is not compatible with Macbook/laptop/PC/mobile devices. It is designed for use with PA systems, amplifiers, and speakers.

Maintenance

  • Cleaning: Use a soft, dry cloth to clean the microphone and receiver. Do not use liquid cleaners or solvents.
  • Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
  • Battery Care: To prolong battery life, avoid fully discharging the battery frequently. If storing for an extended period, charge the battery to about 50% every few months.
  • Handling: Handle the microphone and receiver with care. Avoid dropping them or subjecting them to strong impacts.
