10. Setting Tone Modes
Selection of the tone mode is generally a subjective choice based on what sounds best to you.
Specifically: Normal mode is the most neutral, Enhanced mode provides a tighter sound,
Warm mode adds midrange with slight treble reduction, and Low frequency reduction mode is
intended to control bass in smaller rooms or on “boomy” recordings.
