3.1 Control Spheres

The Mojo 2 features illuminated control spheres for intuitive operation. While the color-coded system may require some familiarization initially, it provides comprehensive control over the device's functions.

Figure 3: The illuminated control spheres on the top of the Mojo 2.

Refer to the quick start guide or the full manual (available on the manufacturer's website) for a detailed explanation of each sphere's function and corresponding color codes for volume, input selection, and menu navigation.

3.2 UHD DSP (Digital Signal Processing)

A key new feature of the Mojo 2 is its innovative UHD DSP, which allows for lossless Equalization (EQ) adjustments. This enables users to fine-tune the sound to their personal preferences or to compensate for the tonal characteristics of different headphones without degrading audio quality.

The UHD DSP menu is accessed via the control spheres. Experiment with the settings to achieve your desired sound profile. Detailed instructions for navigating the DSP menu are provided in the full user manual.

3.3 Crossfeed Feature

The Mojo 2 includes a crossfeed function designed to create a more natural, speaker-like listening experience when using headphones. This feature subtly blends the left and right channels to reduce the "in-head" localization often associated with headphone listening, potentially enhancing comfort during long listening sessions.

Activate or deactivate the crossfeed feature through the control sphere menu to determine your preferred listening mode.

5 การแก้ไขปัญหา

If you encounter issues with your Mojo 2, please refer to the following common troubleshooting steps:

• ไม่มีเสียงออก:
  • Verify that your headphones are properly connected to one of the 3.5mm output jacks.
  • Check the volume level on the Mojo 2 and your source device. Ensure the volume is not muted or set too low.
  • Confirm that the correct input source is selected on the Mojo 2 using the control spheres.
  • Ensure the source device is playing audio and its output is directed to the Mojo 2.
• Device Not Charging/Power Issues:
  • Ensure the Micro USB charging cable is securely connected to both the Mojo 2 and a working power source.
  • Try a different Micro USB cable and/or power adapter to rule out faulty accessories.
  • Allow the device to charge for at least 30 minutes before attempting to power it on if the battery is completely depleted.
• เสียงขาดๆ หายๆ/เสียงผิดเพี้ยน:
  • Check all cable connections (input and output) for looseness or damage.
  • มั่นใจในเสียง files or streaming quality from your source are not corrupted or of low bitrate.
  • If using a computer, ensure the correct audio drivers are installed and updated.
  • Try a different source device or different headphones to isolate the issue.
• Control Spheres Unresponsive/Confusing:
  • Power cycle the device (turn off and on again).
  • Refer to the detailed user manual for specific color codes and button press sequences for advanced functions like DSP and crossfeed.
