1. Připojení napájení: Connect a DC 12V power supply to the "DC 12V" terminals. Ensure the positive (+) and negative (-) terminals are connected correctly. The module supports a maximum of 18V DC.
2. Připojení reproduktorů:
   • Connect the left channel speaker to the "L+" and "L-" terminals.
   • Connect the right channel speaker to the "R+" and "R-" terminals.
   • Ensure speakers have an impedance of 4-8 ohms.
3. Připojení zvukového vstupu: Vyberte jednu z následujících metod:
   • Connect your audio source (e.g., smartphone, MP3 player) to the 3.5mm audio input jack.
   • Alternatively, use the provided 3P shielded audio cable to connect to the 3P audio input port for custom installations.

6. Návod k obsluze

1. After completing all connections, ensure the volume knob is set to a low level (fully anticlockwise).
2. Zapněte napájení modulu.
3. Spusťte přehrávání zvuku z připojeného zdroje.
4. Slowly rotate the volume knob clockwise to increase the audio output to your desired level. Rotate anticlockwise to decrease volume.

7. Údržba

• Udržujte amplifier module clean and dry. Avoid exposure to dust, moisture, and extreme temperatures.
• Pravidelně kontrolujte všechna kabelová připojení, abyste se ujistili, že jsou bezpečná a bez koroze.
• Ensure the heatsink remains free of obstructions to allow for proper heat dissipation.
• For optimal thermal performance, it is recommended to ensure thermal compound is applied between the TDA7377 IC and the heatsink. If not present, carefully apply a thin layer of high-quality thermal paste.
