4. Operating Instructions

4.1 Power On/Off

To power on the transmitters and receiver, simply remove them from the charging case. They will automatically power on and attempt to pair. To power off, place them back into the charging case.

4.2 Pairing

The transmitters and receiver are pre-paired at the factory. If re-pairing is needed, consult the on-screen instructions on the receiver or refer to the full digital manual on the SYNCO website.

4.3 Intelligent Noise Cancellation 2.0

The SYNCO G4 features 2.0 intelligent noise cancellation to reduce ambient noise. This function can be activated or deactivated via the controls on the transmitter or receiver, depending on the specific model variant. When active, it reduces noise from 90dB to 60dB, enhancing vocal clarity.

The system includes a built-in -6dB safety channel. This feature records a secondary audio track at a lower volume, preventing audio clipping or distortion from sudden loud sounds during recording. This ensures a clean, usable backup track.

5. Maintenance

To ensure optimal performance and longevity of your SYNCO G4 system:

  • Cleaning: The units are liquid and dust resistant. Wipe them with a soft, dry cloth. For stubborn marks, a slightly damp cloth can be used, ensuring no moisture enters ports.
  • Storage: Store the system in its charging case when not in use to protect it from dust and physical damage. Store in a cool, dry place away from direct sunlight and extreme temperatures.
  • Battery Care: For long-term storage, ensure the batteries are charged to approximately 50-70% to maintain battery health. Recharge every few months if not in use.

6. Troubleshooting

If you encounter issues with your SYNCO G4 system, try the following steps:

  • No Sound/Low Volume:
    • Ensure the receiver is correctly connected to your recording device.
    • Check that both transmitters and receiver are powered on and paired.
    • Verify the volume/gain settings on your recording device and the G4 receiver.
    • Confirm the microphone input is selected on your recording device.
  • Interference/Poor Connection:
    • Ensure transmitters and receiver are within the 200m operating range.
    • Avoid obstacles (walls, large metal objects) between the transmitter and receiver.
    • Move away from other 2.4GHz wireless devices that may cause interference.
    • Re-pair the devices if the connection is unstable.
  • Battery Not Charging:
    • Ensure the USB-C cable is securely connected to the charging case and power source.
    • Try a different USB-C cable and power adapter.
