3.2. Connecting to Recording Devices
- Power On: Press and hold the power button on both the Transmitter(s) and the Receiver until the TFT display illuminates.
- Pairing: The units should automatically pair. If not, refer to the troubleshooting section or use the eject pin to reset if necessary.
- Connecting to Camera (DSLR/Mirrorless): Use the 3.5mm TRS Camera Cable. Connect one end to the 'OUT' port on the Receiver and the other end to the microphone input port on your camera.
- Connecting to Smartphone/Tablet: Use the 3.5mm TRRS Phone Cable (or optional Android/iPhone cable). Connect one end to the 'OUT' port on the Receiver and the other end to the headphone/microphone jack of your smartphone or tablet.
- Microphone Connection: The Transmitter has a built-in microphone. For enhanced audio quality or discreet placement, connect the External Lav Mic (with Wind Muff) to the 'MIC' input on the Transmitter.
4. Operating Instructions
4.1. Display Screens
The SYNCO G2 features clear TFT display screens on both the Transmitter and Receiver, providing real-time information about the system's status.
RX Receiver Display:
- Recording Mode: Indicates Mono or Stereo mode.
- Power Indicator: Shows battery level.
- Channel A/B Gain: Displays the current gain level for each channel.
- Channel A/B Audio Dynamic Display: Visual representation of audio input levels.
TX Transmitter Display:
- Recording Indicator: Shows when recording is active.
- Muting Indicator: Displays when the microphone is muted.
- Connection Status: Indicates Disconnected, Connecting, or Connected status.
- Low Cut On: Shows when the low-cut filter is active.
4.2. Gain Adjustment
The Receiver features a wide gain range (0-5 Level) to adjust the output volume to match your recording device's input sensitivity. Use the '+' and '-' buttons on the Receiver to increase or decrease the gain level as needed.
4.3. One-Button Muting
Each Transmitter is equipped with a one-button muting switch. Press the 'MUTE' button on the side of the Transmitter to instantly mute or unmute the microphone. The display will indicate the muting status.
4.4. Low-Cut Function
The Transmitter includes a 150Hz optional low-cut filter. Press the 'Low Cut' button on the Transmitter to activate or deactivate this function. The low-cut filter helps to reduce unwanted low-frequency noise, such as wind noise or rumble, improving audio clarity.
4.5. Real-time Audio Monitoring
Connect headphones to the 3.5mm headphone jack on the Receiver to monitor your audio in real-time. This allows you to ensure optimal sound quality and detect any issues during recording.
4.6. Recording Modes (G2A2 only)
For the G2A2 system with two transmitters, the receiver supports both Mono and Stereo recording modes, allowing for flexible 2-person recording setups.
4.7. Digital Signal Processing (DSP) Chip
The SYNCO G2 incorporates a built-in Digital Signal Processing (DSP) chip, which helps to reduce noise and latency, ensuring a cleaner and more stable audio signal.
4.8. Transmission Range
The system offers a stable transmission range of up to 492ft/150m line-of-sight, utilizing Digital 2.4GHz technology for reliable wireless performance.
5. Maintenance
5.1. Battery Care
- To prolong battery life, avoid fully discharging the devices frequently.
- Charge the devices regularly, even if not in use, to maintain battery health.
- Store the devices in a cool, dry place away from extreme temperatures.
5.2. Cleaning
- Use a soft, dry cloth to clean the exterior of the transmitters and receiver.
- Do not use liquid cleaners or solvents, as they may damage the device.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No audio output | Device not powered on, not paired, incorrect cable connection, muted microphone, low gain. | Ensure all units are powered on and paired. Check cable connections to recording device. Verify microphone is not muted. Adjust receiver gain. |
| Poor audio quality (noise, static) | Interference, distance from receiver, low battery, low-cut filter off in noisy environment. | Ensure clear line-of-sight between transmitter and receiver. Charge batteries. Activate 150Hz low-cut filter if ambient noise is present. Avoid strong electromagnetic interference. |
| Devices not pairing | Out of range, pairing error. | Bring units closer together. Use the provided eject pin to perform a reset on both the transmitter(s) and receiver, then power cycle. |
| Short battery life | Old battery, frequent deep discharge. | Ensure full charge before use. Avoid leaving devices fully discharged for extended periods. |

8. User Tips
- Optimal Placement: For best audio quality, position the lavalier microphone (or the built-in mic if used directly) about 6-8 inches from the speaker's mouth.
- Monitor Audio: Always use headphones connected to the receiver to monitor audio in real-time. This helps catch any issues like clipping, interference, or accidental muting before recording.
- Use Low-Cut Filter: In outdoor environments or places with ambient low-frequency noise (e.g., air conditioning hum, traffic rumble), activate the 150Hz low-cut filter on the transmitter to improve vocal clarity.
- Check Battery Levels: Regularly check the battery indicators on both transmitters and the receiver, especially before long recording sessions, to avoid unexpected power loss.
- Secure Connection: Ensure all cables are securely plugged in to prevent accidental disconnections during recording.
