Setup Guide
Follow these steps to set up your XTUGA SF-1 wireless system:
- Charge the Units: Connect both the transmitter and receiver to a USB power source using the provided charging cables. The CHR light on the receiver will turn red while charging. Once fully charged, the light will turn off or change color (refer to the display for battery level).
- Connect Transmitter to Microphone: Plug the XTUGA SF-1 Transmitter directly into the XLR output of your wired microphone.
- Connect Receiver to Audio Input: Plug the XTUGA SF-1 Receiver into an available XLR input on your mixing console, recorder, speaker, or other audio equipment.
- Using Converters (Optional): If your audio equipment uses 6.35mm (1/4 inch) inputs instead of XLR, use the provided XLR to 6.35mm converter to connect the receiver. Similarly, if your microphone has a 6.35mm output, use the 6.35mm to XLR converter to connect it to the transmitter.
Operating Instructions
- Power On/Off: Long press the 'POWER' button on both the transmitter and receiver to turn them on or off.
- Frequency Matching: The units should automatically pair. After successful RF light matching, the RF light on the receiver will turn red. The AF light on the receiver will blink when it receives a sound signal from the transmitter.
- Switching Frequency: On the transmitter, short press the 'CH' (Channel) button to cycle through the 16 available frequencies. This helps avoid interference.
- Adjusting Volume: On the transmitter, short press the 'VOL' (Volume) button to adjust the output volume in 5 levels.
- Switching Power Supply Mode (for Microphones):
The SF-1 offers three voltage adjustment modes to accommodate different microphone types. Press and hold the 'VOL' button on the transmitter for 5 seconds to switch between modes:- 0V (Dynamic Mic Mode): For standard dynamic microphones.
- 5V (Audio Mode): For condenser microphones or recording microphones that require 5V power.
- 48V (Condenser Mic Mode): For phantom-powered condenser microphones.
Note: Please confirm your microphone type before use and select the corresponding mode to prevent damage to your microphone or the device.
Three power supply modes for dynamic, 5V condenser, and 48V phantom-powered condenser microphones.
User Tips
- Frequency Range: The operating frequency range is 572 to 596 MHz. If you experience interference, try switching to a different channel using the 'CH' button.
- Multiple Units: The system supports up to 16 adjustable frequency points, allowing multiple groups to be used simultaneously without interfering with each other. Ensure each pair (transmitter/receiver) is set to a unique channel.
- Battery Life: The built-in battery provides approximately 6 hours of usage. Keep the units charged for uninterrupted performance.
- Microphone Compatibility: Always verify your microphone's power requirements (dynamic, 5V condenser, or 48V phantom) and select the correct power supply mode on the transmitter to ensure proper operation and prevent damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Units not powered on, low battery, incorrect connections, frequency mismatch, incorrect microphone mode. | Ensure both units are powered on and charged. Check all cable connections. Verify transmitter and receiver are on the same frequency. Confirm correct power supply mode for your microphone. |
| Interference or static noise | Other wireless devices, obstacles, or being too far from the receiver. | Change the frequency channel on the transmitter. Ensure a clear line of sight between transmitter and receiver. Reduce distance between units. Turn off other interfering wireless devices. |
| Short transmission range | Obstacles blocking signal, excessive distance. | Ensure a clear line of sight. Avoid placing units behind large metal objects or walls. Reduce the distance between the transmitter and receiver. |
| AF light not blinking with sound | No audio input to transmitter, transmitter not paired, microphone issue. | Check microphone connection and functionality. Ensure transmitter is powered on and paired with the receiver. |
| Battery drains quickly | Aging battery, continuous high power usage. | Ensure units are fully charged before use. If battery life significantly degrades, contact support. (Note: Batteries are built-in and not user-replaceable.) |
Maintenance
- Cleaning: Use a soft, dry cloth to clean the surface of the transmitter 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: For optimal battery life, avoid fully discharging the units frequently. Recharge them regularly, even if not in use for extended periods.
