3.1. 2-IN-1-OUT Configuration

This configuration allows you to connect two audio sources to the MC102 and select one to output to a single audio device (e.g., active speakers, headphones).

1. Connect your first audio source (e.g., CD player, computer) to the A 입력 잭.
2. Connect your second audio source (e.g., smartphone, tablet) to the B Input Jack.
3. Connect your audio output device (e.g., active speakers, headphones) to the IN/OUT Jack.

3.2. 1-IN-2-OUT Configuration

This configuration allows you to connect one audio source to the MC102 and output the audio to two different audio devices (e.g., headphones and active speakers), selecting which one is active.

1. Connect your audio source (e.g., computer, smartphone) to the IN/OUT Jack.
2. Connect your first audio output device (e.g., active speakers) to the A 입력 잭.
3. Connect your second audio output device (e.g., headphones) to the B Input Jack.

5. 중요 사항 및 고려사항

Please observe the following important notes for optimal performance and compatibility:

1. 업그레이드된 구성 요소: The MC102 Black version features customized potentiometers and isolation modules designed to minimize potential volume adjustment issues and background noise.
2. Turntable Incompatibility: The MC102 is not compatible with turntables directly. PHONO signals are typically too low, resulting in lower than usual output. Direct connection may not work effectively.
3. 패시브 스피커 연결: This device cannot be connected directly to passive speakers. To use with passive speakers, you must connect your sound source to a preamplifier, then to the MC102, and finally to active speakers. Alternatively, connect your sound source to the MC102, then to an amp증폭기를 거쳐 마지막으로 수동 스피커로 연결됩니다.
4. New 3.5mm Port: A new 3.5mm port has been added between the original A and B ports for user convenience, allowing all cables to be connected on one side. However, the opposite 3.5mm port (the main IN/OUT port) still has priority over this new port.

6. 유지관리

To ensure the longevity and optimal performance of your Nobsound Little Bear MC102, follow these maintenance guidelines:

• 청소: 기기 외부를 닦을 때는 부드럽고 마른 천을 사용하십시오. 액체 세척제나 용제는 마감재나 내부 부품을 손상시킬 수 있으므로 사용하지 마십시오.
• 환경: Store and operate the device in a dry, dust-free environment. Avoid exposure to extreme temperatures, humidity, or direct sunlight.
• 손질: 기기를 조심스럽게 다루십시오. 떨어뜨리거나 강한 충격을 주지 마십시오.
• 사이: 모든 케이블 연결을 주기적으로 점검하여 안전하고 손상이 없는지 확인하세요.

7. 문제 해결

If you encounter issues with your MC102, refer to the following troubleshooting steps:

• 사운드 출력 없음:
  • Verify all audio cables are securely connected to the correct ports on the MC102 and your audio devices.
  • Ensure the volume control knob on the MC102 is not set to minimum.
  • Check if the mute button is engaged. Press it to disengage.
  • Confirm that your audio source device is playing audio and its volume is adequately set.
  • If using the 1-IN-2-OUT configuration, ensure the correct output channel (A or B) is selected.
• Humming or Background Noise:
  • 모든 케이블이 양호한 상태이고 적절하게 차폐되어 있는지 확인하십시오.
  • Try using different audio cables to rule out faulty cabling.
  • Disconnect other electronic devices that might be causing interference.
  • As a passive device, the MC102 relies on the quality of the input signal. If the source signal is noisy, the output will reflect this.
• Low Volume Output:
  • Increase the volume on both your audio source device and the MC102.
  • Ensure you are not attempting to connect a turntable directly, as the PHONO signal level is too low for this passive device.
  • If connecting to passive speakers, confirm that an external amplifier is used, as the MC102 does not provide amp합리화.
