3. Eto ati Asopọ

The MC102 offers flexible connection options for various audio setups. Ensure all devices are powered off before making connections.

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 Jack Input.
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 Jack Input.
3. Connect your second audio output device (e.g., headphones) to the B Input Jack.

5. Important Notes and Considerations

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

Image 6: Important notes for the MC102, detailing specific usage conditions and features.

1. Upgraded Components: 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. Passive Speaker Connection: 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 amplifier, and finally to passive speakers.
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. Itọju

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

7. Laasigbotitusita

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

• Ko si Ijade ohun:
  • 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:
  • Rí i dájú pé gbogbo àwọn okùn wa ní ipò tó dára àti pé wọ́n ní ààbò tó yẹ.
  • 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 amplification.
