How to adjust the audio equalizer on the Reiz?

[McGavin]

First, open the player and play a song, then select the equalizer. After that, you can proceed with the corresponding settings. The car audio equalizer is an electronic device that can adjust the amplification of various frequency components in the electrical signal. It compensates for defects in car speakers or the sound field by adjusting electrical signals of different frequencies. Below is relevant information about the Reiz audio equalizer: 1. Sub-bass: 20Hz-40Hz, when properly adjusted, the sound is strong and powerful. It controls sounds like thunder, bass drums, pipe organs, and bass. Excessive boosting can make the music muddy. 2. Bass: 40Hz-150Hz, this is the foundational part of the sound, accounting for 70% of the entire audio energy. It is a crucial component in expressing musical style. When properly adjusted, the bass is balanced, and the sound is full and soft. Insufficient adjustment makes the sound thin. At 150Hz, excessive boosting can make the sound muffled, reduce brightness, and increase nasality. 3. Mid-bass: 150Hz-500Hz, this is the structural part of the sound, where the human voice is located. Insufficient adjustment can cause the vocal to be drowned out by the music, making the sound weak. Proper boosting makes the sound robust and powerful, enhancing its strength and loudness. Excessive boosting can make the bass harsh. Boosting 300Hz by 3-6dB excessively, especially with added reverb, can severely affect sound clarity. 4. Midrange: 500Hz-2KHz, this includes the lower harmonics and overtones of most instruments and is characteristic of snare drums and percussion. Proper adjustment makes the sound clear and bright, while insufficient adjustment makes it muffled. Excessive boosting can produce a telephone-like sound. 5. Upper midrange: 2KHz-5KHz, this is characteristic of string instruments (the friction of the bow on strings in bowed instruments, the sound of fingers plucking strings). Insufficient adjustment reduces the sound's penetration, while excessive boosting can mask the recognition of speech syllables. 6. Treble: 7KHz-8KHz, this frequency affects the sense of sound layering. Excessive boosting can make the sound of piccolos and flutes stand out, increase sibilance in speech, and make the timbre harsh. 7. Super treble: 8KHz-10KHz, when properly adjusted, the metallic clarity of triangles and cymbals is high, and the rhythm of a sand clock is distinct. Excessive boosting can make the sound unnatural and risk burning out high-frequency units.
