This thesis presents a project of an analog channel strip and it’s implementation. It is composed by a pre-amplifier, equalizer, insert, fader and panpot. Each stage has it’s own section and is shown a range of possible topologies based on the reference literature. After the analysis of the topologies, one of them is chosen by it’s reasons that are explained along the text, including the implementation and the mathematical modeling of the project. In the stage of the pre-amplifier, for it’s importance as one of the main functions and it’s influence in the results, has a deep study for each of it’s components. The equalizer is based on topologies suggested by books and equalizers in the market, as the following stages. The final result was satisfactory because of it’s low level of total harmonic distortion, approximately 0,04%, compared to the fist tests that were over 1%. Every stage is functional and has it’s technical features detailed. Also the results, that reached values near to the commercial products, are shown with the pictures of the printed circuit boards. |
