Description: NF-modulation control circuit to control the sound quality, bass and treble enhancement and attenuation, it is not due to only subtle frequency characteristics of compensation. Described there, if you want the audible frequency band domain at any frequency can be changed, the general use of the device is called a graphic equalizer. Example of using DSP is increasing, if you want to use a simple circuit using OP amplifier is better. The graphic equalizer is the center frequency of the compensation split 5-7, respectively, to control by five RLC circuit is very useful. The split frequency is audible frequency range for the axis of symmetry equalization allocation decisions.
