Rolls HE18 험 제거기 사용 설명서

1. 서론

The Rolls HE18 Hum Eliminator is a passive audio device designed to remove unwanted hum and buzz caused by ground loops in audio systems. This unit requires no external power and effectively isolates ground paths, converting unbalanced signals to balanced for cleaner audio transmission.

2. 주요 특징

• Removes buzz or hum caused by ground loops.
• Passive operation, requiring no external power supply.
• Converts unbalanced audio signals to balanced.
• Features both RCA and 1/4" (6.35mm) input/output connections.

3. 중요한 안전 정보

Please read and understand the following safety guidelines before using the Rolls HE18 Hum Eliminator:

• 기기를 습기, 비 또는 극한 온도에 노출시키지 마십시오.
• 장치를 열원 근처나 직사광선에 노출시키지 마십시오.
• This device is passive and does not require external power. Do not attempt to connect it to a power source.
• Ensure all audio cables are securely connected to prevent signal loss or intermittent operation.
• c를 열려고 시도하지 마십시오.asing or modify the unit. There are no user-serviceable parts inside.

4. 설정 지침

The Rolls HE18 is designed for straightforward integration into your audio system. Follow these steps to connect the device:

4.1 Identifying Connections

The HE18 features both RCA and 1/4" (6.35mm) input and output jacks for stereo audio signals. Each channel (Left and Right) has dedicated input and output connections.

4.2 연결 단계

1. Identify the Source and Destination: Determine which audio component is producing the hum (source) and which component is receiving the signal (destination). The HE18 should be placed between these two components.
2. 입력 단자 연결: Connect the audio output from your source device (e.g., mixer, preamplifier) to the corresponding LEFT INPUT and RIGHT INPUT jacks on the HE18. You can use either RCA cables or 1/4" (6.35mm) TS cables.
3. 출력 연결: Connect the LEFT OUTPUT and RIGHT OUTPUT jacks of the HE18 to the audio input of your destination device (e.g., amplifier, powered speakers). Ensure you use the same type of cables (RCA or 1/4" TS) as used for the inputs.
4. 전원 켜기: Once all connections are secure, power on your audio components. The HE18 operates passively and does not require its own power.

The HE18 will automatically isolate the ground paths, reducing or eliminating ground loop hum.

5. 운영

The Rolls HE18 Hum Eliminator functions as a transparent audio interface. Once connected, it continuously works to isolate ground loops without requiring any user adjustments. Its passive design ensures reliable operation without the need for power adapters or batteries.

6. 유지관리

The HE18 is a robust device designed for long-term use with minimal maintenance. To ensure optimal performance and longevity:

• 부드럽고 마른 천으로 닦아 제품을 깨끗하게 유지하십시오. 액체 세척제나 용제 사용은 피하십시오.
• 기기를 직사광선과 극한 온도 변화를 피해 건조한 곳에 보관하십시오.
• 케이블 연결 상태를 정기적으로 점검하여 안전하고 손상되지 않았는지 확인하십시오.

7. 문제 해결

If you encounter issues while using the HE18, refer to the following troubleshooting guide:

• Hum Persists:
  • 모든 오디오 케이블이 완전히 삽입되어 단단히 고정되었는지 확인하십시오.
  • Verify that the hum is indeed a ground loop issue. The HE18 is designed to address ground loop hum, not other types of interference (e.g., radio frequency interference, cable noise).
  • Try isolating other components in your audio chain to pinpoint the exact source of the ground loop.
  • Ensure you are connecting the HE18 between the correct components that are part of the ground loop.
• Signal Loss or Degradation:
  • Check the integrity of your audio cables. Replace any damaged cables.
  • Confirm that the HE18 is connected correctly: source output to HE18 input, and HE18 output to destination input.
  • While designed for minimal impact, passive devices can sometimes introduce slight signal attenuation or impedance mismatches depending on the specific characteristics of the connected equipment. If significant degradation occurs, consult the specifications of your other audio components.
