Frequently Asked Questions
A graphic equalizer is an audio processing unit containing sliders mapped to specific frequency bands. By sliding them up or down, you boost or cut volume in those specific frequency regions.
A 10-band EQ splits the frequency spectrum into octaves, which is perfect for general shaping. A 31-band EQ splits octaves into thirds, offering micro-level control over narrow peaks and room resonances.
