3. Varnostna navodila
- Always use a DC power supply within the specified voltage območje (12V do 18V).
- Ensure correct polarity when connecting the power supply to avoid damage to the module.
- Avoid short-circuiting the output terminals or power input.
- Do not operate the module in wet or excessively humid environments.
- Keep the module away from children and pets.
- Zagotovite ustrezno prezračevanje okoli hladilnika, da preprečite pregrevanje, zlasti med dolgotrajnim delovanjem z visoko porabo energije.
- Pred kakršnimi koli priklopi ali odklopi izklopite napajanje.

- Priključek za napajanje: 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.
- Priključki zvočnikov:
- 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.
- Avdio vhodna povezava: Izberite enega od naslednjih načinov:
- 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. Navodila za uporabo
- After completing all connections, ensure the volume knob is set to a low level (fully anticlockwise).
- Napajajte modul.
- Start playing audio from your connected source.
- Slowly rotate the volume knob clockwise to increase the audio output to your desired level. Rotate anticlockwise to decrease volume.
7. Vzdrževanje
- Obdrži amplifier module clean and dry. Avoid exposure to dust, moisture, and extreme temperatures.
- Občasno preverite vse ožičene povezave, da se prepričate, da so varne in brez korozije.
- 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.
