5. 설정 지침
Careful connection is essential for proper operation and to prevent damage to the amplifier board and connected equipment. Ensure all connections are secure before applying power.
5.1 전원 공급 장치 연결
Connect a DC power supply within the range of 19V to 52V to the designated power input terminals on the board. Observe correct polarity (positive and negative). The terminals are typically labeled 'DC 19V-50V' or similar.
5.2 오디오 입력 연결
오디오 소스(예: DAC, 프리앰프)를 연결하세요.amplifier) to the 2 VRMS analog input interface. The input terminals are typically labeled 'INPUT L', 'G' (Ground), and 'R'. Use appropriate shielded audio cables to minimize noise.
5.3 Speaker Output Connection
Connect your passive speakers to the output terminals. Ensure correct polarity for each channel (Left+ L-, Right+ R-). The board supports speaker impedances of 2, 4, or 8 ohms. Verify your speakers' impedance matches the ampLifier의 능력.
6. 사용 설명서
Once all connections are made, you can begin operating the amp증폭기 보드:
- 전원 켜기: Connect the power supply to a wall outlet. The amplifier board should power on, indicated by any onboard LEDs (if present).
- 오디오 재생: 연결된 소스에서 오디오 재생을 시작하세요.
- 볼륨 조절: Adjust the volume using your audio source or any external preamplifier connected to the input. This amplifier board does not have onboard volume control.
- 전원 끄기 : Disconnect the power supply from the wall outlet to power off the amp리퍼 보드.
7. 유지관리
수명과 최적의 성능을 보장하려면 amp증폭기 보드의 경우 다음 유지 관리 지침을 따르십시오.
- 깨끗하게 유지하십시오: Regularly clean the board with a soft, dry cloth. Avoid using liquids or abrasive cleaners.
- 습기를 피하세요: 유지하다 amplifier board away from water, humidity, and other liquids.
- 정전기 방전 방지: Handle the board with care, especially when installing or removing, to avoid electrostatic discharge (ESD) which can damage components.
- 환기를 보장하십시오: The heatsink is crucial for dissipating heat. Ensure it is not obstructed and that there is adequate airflow around the board, especially during prolonged operation at high power.
- 저장: 장기간 사용하지 않을 경우, 기판을 건조하고 먼지 없는 곳에 보관하십시오.
8. 문제 해결
S에 문제가 발생하면AMP-200 amp앰프 보드와 관련된 일반적인 문제점 및 해결 방법은 다음과 같습니다.
8.1 사운드 출력 없음
- 전원 확인: 전원 공급 장치가 올바르게 연결되어 지정된 전압을 공급하는지 확인하십시오.tage (19V-52V DC).
- 오디오 입력을 확인하세요: Verify that the audio source is connected correctly to the input terminals and is playing audio.
- 스피커 연결 상태를 확인하세요: Ensure speakers are properly connected to the output terminals with correct polarity.
- 볼륨 레벨: Confirm that the volume on your audio source or preamplifier가 최소 또는 음소거로 설정되어 있지 않습니다.
8.2 왜곡된 소리
- 입력 레벨: Reduce the input signal level from your audio source. An excessively high input signal can cause distortion.
- 전원 공급 장치: Ensure the power supply is stable and can provide sufficient current for the desired output level. Fluctuations or insufficient current can lead to distortion.
- 스피커 임피던스: Verify that your speakers' impedance is compatible with the amplifier (2, 4, or 8 ohms).
8.3 낮은 출력 전력
- 전원 공급 장치tage: As noted in the specifications, lower input voltage will result in reduced output power. Ensure your power supply is providing adequate voltage, ideally closer to the upper limit (52V) for maximum output.
- 스피커 임피던스: Lower impedance speakers (e.g., 2 ohms) will draw more current and allow for higher power output compared to higher impedance speakers (e.g., 8 ohms) at the same voltage.
9. 사용자 팁
- 전원 공급 장치 선택: For optimal performance and to achieve the advertised maximum output power, it is highly recommended to use a robust power supply capable of delivering up to 52V DC with sufficient current capacity (e.g., 20A or more). This will allow the amplifier to operate at its full potential.
- 열 관리: While the board includes a heatsink, consider additional cooling solutions (e.g., a small fan) if operating at very high power levels for extended periods, especially if enclosed in a case.
