Summary: | The electronic drums is an instrument that needs an external system to be able to hear it. For this, you need to use an audio monitor. The audio monitor is nothing more than a sound box in which equalizer, amplifier circuits are inserted, and the drums audio signal can be reproduced. The circuits of this type of equipment are mostly analog, as this is where the best performance and fidelity is achieved. In this project was developed the sound box, equalizer, amplifier and reverberation effect for the audio monitor, having as main focus the equalizer, since the method used for frequency adjustment is not common in the equipment currently found. This method consists of the use of digital potentiometers, controlled by a microcontroller and which assume a resistance value from commands of a touchscreen display. This value directly affects the behavior of the filters, with respect to either attenuation or gain of the audio signal passing through them. |
