4. 유지관리
To ensure the longevity and optimal performance of your Gustard DAC-R26 II, follow these maintenance guidelines:
- 청소: 제품 외부를 닦을 때는 부드럽고 마른 천을 사용하십시오. 액체 세척제, 스프레이 또는 연마성 물질은 마감재나 내부 부품을 손상시킬 수 있으므로 사용하지 마십시오.
- 통풍: Ensure the unit is placed in a well-ventilated area. Do not block the ventilation slots. Proper airflow prevents overheating and maintains stable operation.
- 환경: Keep the DAC away from direct sunlight, heat sources, excessive dust, and moisture. The operating temperature should not exceed 50 degrees Celsius.
- 전원 끄기 : When not in use for extended periods, it is recommended to power off the unit and disconnect it from the AC outlet.
5. 문제 해결
If you encounter issues with your DAC-R26 II, refer to the following common troubleshooting steps:
- 전원 없음:
- 전원 코드가 본체와 콘센트에 제대로 연결되어 있는지 확인하십시오.
- Verify that the AC voltage switch on the rear panel is set correctly for your region.
- Test the AC outlet with another device to ensure it is functional.
- 사운드 출력 없음:
- Ensure the correct input source is selected on the DAC.
- Verify that the analog output cables (RCA or XLR) are securely connected to both the DAC and your amp리퍼/프리amp리퍼.
- 볼륨 레벨을 확인하세요 amp리퍼/프리amp리퍼.
- Confirm that your audio source is playing and sending a signal.
- 왜곡된 소리:
- 느슨한 케이블 연결을 확인하십시오.
- s를 확인하십시오ample rate and bit depth settings on your audio source match the DAC's capabilities for the selected input.
