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.
