AUDIO EQUALIZER CIRCUIT PC

Referring to the given circuit diagram we can see that the associated opamps form the main active component responsible for the required optimizations. How the 10 band graphic equalizer circuit functions The circuit also includes a fixed 10kHz low pass filter stage for cancelling out unwanted noise such as hiss or other high frequencies disturbances. Typically the controls would be able to provide upto 10dB of boost or cut at nominal center frequencies of 150Hz, 500Hz, 1kHz, 2kHz, 5kHz, 7kHz, 10kHz, 13kHz, 15kHz, 18kHz. Or perhaps you can roll off the high pitched even to further extents in case you wished, or simply heightened the bas boost to your liking. You would be able to tailor the sound as per your preferred tastes.As an example, the midrange controls of the equalizer can be adjusted to highlight dialogue or in order to reduce the harshness over a particular range of voice audio. Next, it would be just a matter of adjusting the given 10 band controls and enjoying the vastly improved sound quality.

All one has to do is feed the TV or PC audio input to this circuit and hook the output with the existing home theater amplifier. To be precise, the unit can prove effective in virtually any form of audio application.

The circuit can be easily converted to a 5 band graphic equalizer by simply eliminating 5 stages from the shown design The Circuit ConceptĪ graphic equalizer is a type of complex tone control circuit which can be applied to smooth out or enhance the frequency response of any hi-fi audio amplifier, or in a guitar effects unit.
