If you want to increase treble, you may go to, say, 2KHz, and turn the volume up. In order for an equalizer to know

which frequency range to adjust, it operates on the concept of filtering, meaning it must filter the individual frequencies so they can be individually adjusted. So equalizers are made up of filters. An equalizer consists of one or or filters which can cut or boost the amplitude of frequencies in various ranges. The treble control cuts or boosts the response above 1KHz to a maximum of about 20dB at 10KHz. The bass control cuts or boosts the response below 1KHz to a maximum of about 20dB at 50Hz.
