6.3 TWS (True Wireless Stereo) Pairing
This product supports TWS pairing between two amplifier boards to create a stereo system. One unit will act as the Master, and the other as the Slave.
Video 6.1: TWS Stereo Pairing Demonstration
Figure 6.3: TWS Stereo Pairing Concept
- **Power On Both Boards**: Power on both amplifier boards. The blue indicator lights on both units will flash rapidly. Ensure neither board is paired with a mobile phone via Bluetooth, nor connected via AUX, nor has a USB flash drive inserted.
- **Initiate Pairing**: On one of the amplifier boards, press the multifunction volume knob four (4) consecutive times. The TWS red indicator light on this board will start flashing rapidly. The other board's blue indicator light will continue to flash rapidly.
- **Connection Confirmation**: Wait for the TWS red indicator light on the first board (Master) to change from rapid flashing to a solid ON state. Simultaneously, the blue indicator light on the second board (Slave) will turn OFF, and its red indicator light will start flashing slowly. This indicates successful TWS connection.
- If the red indicator light goes out, the connection has failed. Repeat step 2.
- **Connect Audio Source**: After successful TWS connection, open your phone's Bluetooth settings, search for "XinYi", and connect. Your phone will now play music in stereo through the paired amplifier boards. Alternatively, insert an AUX cable or USB drive into the Master unit to play music.
Cancelling TWS Pairing
During an active TWS connection, press the multifunction volume knob of either amplifier board four (4) consecutive times to exit the TWS pairing mode.
Important Notes for TWS:
- When using the TWS function, always establish the TWS connection between the two amplifier boards before pairing with a mobile phone via Bluetooth.
- The TWS function has a memory mode; the boards will automatically attempt to reconnect in TWS mode the next time they are powered on.

6.4 APP Control
The amplifier board can be controlled via a dedicated mobile application (Sinilink-APP). This allows for changing the Bluetooth name and setting a pairing password.
- Download and install the Sinilink-APP on your mobile device.
- Ensure Bluetooth is enabled on your phone and the amplifier board is connected.
- Open the Sinilink-APP and search for the amplifier board.
- Within the app, you can modify the device name and set a password. Remember to click "Set" to save changes.

7. Maintenance
- Keep the amplifier board clean and free from dust. Use a soft, dry cloth for cleaning.
- Ensure adequate ventilation around the board to prevent overheating, especially during prolonged use at high volumes. The board features a grooved heat sink for thermal dissipation.
- Avoid dropping or subjecting the board to strong impacts.
- Store in a cool, dry place when not in use.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Incorrect speaker connection, no audio input, low volume, power issue. | Check speaker wiring and polarity. Ensure an audio source is connected and playing. Increase volume. Verify power supply is connected and functional. |
| Bluetooth pairing failed | Bluetooth not enabled, device too far, incorrect pairing procedure. | Ensure Bluetooth is enabled on both devices. Keep devices within range. Follow Bluetooth connection steps (Section 6.2). Try restarting both devices. |
| TWS pairing failed (red indicator light goes out) | Incorrect TWS pairing procedure, existing Bluetooth connection. | Repeat TWS pairing steps carefully (Section 6.3). Ensure no mobile phone is connected via Bluetooth and no AUX/USB is inserted during TWS pairing. |
| Distorted sound | Volume too high, poor audio source quality, speaker impedance mismatch. | Reduce volume. Use a high-quality audio source. Ensure speaker impedance matches amplifier specifications. |
| Board not powering on | No power supply, faulty power adapter, incorrect wiring. | Check power adapter connection and functionality. Verify power supply voltage. Ensure power input wiring is correct. |
9. User Tips
- For optimal sound quality, use a stable power supply with sufficient current (3A or above).
- When using TWS, ensure both amplifier boards are placed within reasonable proximity for a stable connection.
- Experiment with different audio sources (Bluetooth, AUX, USB) to find the best fit for your setup and preferences.
- Consider adding an external 2.4GHz antenna via the IPEX interface for improved Bluetooth range and stability, especially in environments with interference.
