2. Connect a suitable DC power supply (18V-48V) to these terminals. Pay close attention to the positive (+) and negative (-) polarity markings to avoid damage.
3. Ensure the power supply is off or unplugged before making the connection.

6. אַפּערייטינג ינסטרוקטיאָנס

1. מאַכט אויף: After all connections are securely made, plug in your DC power supply or switch it on. The board should power up.
2. אַודיאָ פּלייבאַק: Start playing audio from your connected source. The amplifier will output sound through the connected speakers.
3. באַנד קאָנטראָל: Please note that the BDM8-A board does נישט have an onboard volume control. Volume must be adjusted from your audio source (e.g., phone, computer, pre-ampלייבער).
4. מאַכט אַוועק: צו קער אַוועק די amplifier, disconnect or switch off the DC power supply.

7. וישאַלט

• רייניקונג: האַלטן די amplifier board clean and free from dust. Use a soft, dry cloth or a brush to gently remove dust. Do not use liquid cleaners.
• פען טשעק: Periodically check the cooling fan for obstructions or excessive noise. Ensure it spins freely to maintain optimal heat dissipation.
• פֿאַרבינדונגען: Occasionally check all wire connections to ensure they remain secure. Loose connections can lead to poor performance or damage.

8. טראָובלעשאָאָטינג

• קיין קול:
  • Ensure the power supply is connected and providing the correct voltage (18V-48V DC).
  • Verify that the audio source is playing and its volume is turned up.
  • Check all audio input and speaker output connections for proper seating and polarity.
  • Confirm speakers are functional.
• פאַרקרימט סאָונד:
