5. Safety Precautions and Important Notes

• Джерело живлення: Це amplifier board requires a DC power supply. Do NOT use AC power, as this will cause damage.
• томtage and Polarity: Ensure the input power voltage is within the 18-50VDC range. The input power cannot be reversed (incorrect polarity) or exceed 51V, otherwise, the board will be permanently damaged.
• Перемикання: This board does NOT support bridging. The left and right channels cannot be connected together.
• Функціонування вентилятора: Upon power-on, the fan performs a self-check and stops normally after approximately 1 second. It will only activate and run continuously when the board's temperature exceeds 50°C to maintain optimal operating temperature.
• Вимоги до кабелю: Power and audio cables are not included with the product. Please ensure you have appropriate cables for your setup.

6. Інструкції з налаштування

Follow these steps to correctly set up your ZK-6002 ampплата рятувальника:

1. Споживана потужність: Connect a DC power supply (18-50VDC, recommended 36-48VDC, 10A or above) to the power input terminal. This can be done via the 5.5-2.5DC female socket or the 2P terminal block. Ensure correct polarity (positive to positive, negative to negative) and that the voltage не перевищує 51В.
2. Підключення динаміка: Connect your left channel speaker to the 'Connect the left channel speaker' terminals and your right channel speaker to the 'Connect to the right channel speaker' terminals. Ensure proper polarity for each speaker. The board supports 2-8 ohm speakers.
3. Аудіо вхід: Підключіть джерело звуку до amplifier board. You can use either the 3.5MM audio port input or the XH2.54-3P stereo audio input (using the provided 3P double ended shielded wire).
4. Регулювання гучності: The board features a volume control potentiometer with an integrated switch for 0-38dB linear adjustment. This knob also serves as the power switch.

7. Інструкція з експлуатації

1. Увімкнення: After completing all connections as per the setup instructions, turn the volume control potentiometer clockwise until it clicks to power on the amplifier board. The pilot lamp буде висвітлюватися.
2. Регулювання гучності: Continue turning the volume control potentiometer clockwise to increase the volume and counter-clockwise to decrease it.
3. Пілот Лamp: Пілот лamp will stay on when the board is working normally. It will flash if the input voltage падає нижче 18 В.
4. Функціонування вентилятора: The cooling fan will perform a brief self-check upon power-on. It will then remain off until the board's internal temperature exceeds 50°C, at which point it will automatically start to cool the components.
5. Вимкнення живлення: Turn the volume control potentiometer counter-clockwise until it clicks to power off the ampдошка підйому.

8. Технічне обслуговування

• Прибирання: Зберігайте amplifier board clean and free from dust. Use a soft, dry cloth to wipe the surface. For dust accumulation on the fan or heat sink, use compressed air.
• Вентиляція: Забезпечте достатній потік повітря навколо amplifier board to prevent overheating, especially during prolonged high-power operation. Do not obstruct the fan or heat sink.
• Зберігання: When not in use for extended periods, store the board in a dry, cool environment, away from direct sunlight and excessive humidity.
• Огляд: Periodically check all connections for tightness and ensure no wires are frayed or damaged.

9. Вирішення проблем

• Немає живлення/немає звуку:
  • Verify the DC power supply is connected correctly and providing voltage within the 18-50V range.
  • Check power supply polarity. Incorrect polarity will prevent operation and may damage the board.
  • Ensure the volume potentiometer is turned clockwise past the 'off' click.
  • Confirm audio input cables are securely connected to both the source and the ampдошка підйому.
  • Check speaker connections and ensure speakers are functional.
• Пілот Лamp Блимає: Це вказує на вхідний об'ємtage is below 18V. Check your DC power supply to ensure it provides sufficient voltage.
• Перегрів: If the board feels excessively hot and the fan is not running (above 50°C), ensure the fan is not obstructed and there is adequate ventilation. If the fan is running but overheating persists, reduce the load or check for short circuits in the speaker wiring.
• Спотворений звук:
  • Check the audio input signal level; too high a signal can cause distortion.
  • Ensure speaker impedance is within the supported 2-8 ohm range.
  • Verify all connections are secure and free from interference.
• No Fan Operation (when hot): The fan should start when the temperature exceeds 50°C. If it doesn't, check for obstructions or a faulty fan connection.

10. Поради користувача

• Якість блоку живлення: For optimal performance and to achieve the advertised power output, use a high-quality DC power supply with sufficient current capacity (e.g., 36-48VDC, 10A or higher). A stable power source is crucial for sound quality and board longevity.
• Підбір динаміків: While the board supports 2-8 ohm speakers, matching the speaker impedance to the power supply voltage will help maximize output power and efficiency. Lower impedance speakers (e.g., 2Ω) will draw more current and can achieve higher power with appropriate voltage.
• Екранування кабелю: Utilize the provided shielded audio cable or other high-quality shielded cables to minimize interference and ensure a clean audio signal.
• Конструкція корпусу: If integrating the board into an enclosure, ensure proper ventilation holes are designed to allow the cooling fan to operate effectively and prevent heat buildup.
