6. Power Output Guidelines

The actual output power varies depending on the input voltage and speaker impedance. Refer to the table below for typical power output values:

Neem asseblief kennis: Optimal audio output requires sufficient audio input combined with appropriate power supply voltage and current. A higher voltage and current generally result in higher power output. For the same conditions, a smaller speaker impedance will yield greater power.

7. Opstelinstruksies

Follow these steps to set up your Daakro ZK-502L amplifier board:

1. Assemble the Casing (Optional): If your board came with acrylic plates, use the provided screws and spacers to assemble the protective casing around the amplewendiger bord.
2. Koppel luidsprekers: Connect your passive speakers to the Left Channel Output (-L +) and Right Channel Output (-R +) terminals. Ensure correct polarity (+ to + and - to -).
3. Koppel kragtoevoer: Connect a DC 9-24V power adapter (not included) to the Power Input jack. Ensure the power supply meets the voltage and current requirements for your desired output.
4. Aanvanklike volume-instelling: Turn the volume control knob counter-clockwise to its minimum position before powering on.

8. Bedryfsinstruksies

The ZK-502L amplifier board supports two audio input modes:

8.1. Bluetooth-modus

1. Krag aan: Verseker die amplifier board is powered on. The Bluetooth indicator LED will blink, indicating it is in pairing mode.
2. Saambinding: On your audio source device (e.g., smartphone, tablet, PC), enable Bluetooth and search for available devices. Select "ZK-502L" from the list.
3. Verbinding bevestiging: Once successfully paired, the Bluetooth indicator LED will stop blinking and remain solid.
4. Speel oudio: Start playing audio on your connected device. Adjust the volume using the amplifier board's volume knob and your source device's volume controls.

8.2. AUX-invoermodus

1. Koppel AUX-kabel: Insert a 3.5mm audio cable (not included) into the AUX Input jack on the amplifier board. Connect the other end to your audio source device's headphone or audio output jack.
2. Outomatiese skakeling: Die amplifier board will automatically switch to AUX input mode when a cable is detected.
3. Speel oudio: Start playing audio on your connected device. Adjust the volume using the amplifier board's volume knob and your source device's volume controls.

9. Veiligheidsmaatreëls

• Verseker die kragtoevoer voltage is within the DC 9-24V range. Using an incorrect voltage kan die toestel beskadig.
• Do not short-circuit the speaker outputs or power input.
• Avoid exposing the board to moisture, extreme temperatures, or direct sunlight.
• Handle the board with care to prevent damage to components.
• Ontkoppel die krag voordat u enige verbindings of ontkoppelings maak.
• Do not attempt to modify the circuit board, as this will void the warranty and may cause damage.

10. Probleemoplossing

• Geen klank:
  • Check if the power supply is connected correctly and providing the correct voltage.
  • Verify speaker connections for correct polarity and secure contact.
  • Ensure the volume knob is turned up on both the amplifier board and the audio source device.
  • If using Bluetooth, ensure the device is paired and connected. If using AUX, ensure the cable is fully inserted.
• Verwronge klank:
  • Verlaag die volume op beide die amplifier and the source device.
  • Ensure the power supply can provide sufficient current for the desired output power.
  • Check speaker impedance compatibility (4-8Ω).
• Bluetooth-ontkoppeling:
  • Ensure the audio source device is within the 16.4 feet (5 meters) Bluetooth range.
  • Vermy hindernisse wat die Bluetooth-sein kan belemmer.
  • Probeer om die toestel te ontkoppel en weer te koppel.
• Kragindikator nie aan nie:
  • Check the power supply connection and ensure it is functioning.
  • Verify that the power input terminals are correctly wired.
