Σύνοψη

This project deals with the development of a 4-channel audio mixer. A number of different circuits were carefully studied and considering their specifications and some modifications made the best circuit was chosen. After the selection, the +ve film and the p.c.b were developed, the components were located in the appropriate locations and a test was followed to carry out all the different response of the circuit. A +/- 12V power supply is also constructed and tested in order to complete the needs of the project.
The characteristics of the modified circuit are:
a) 2 - Mono inputs for a dynamic microphone with highresistance and a cri stall microphone,
b) 2 - stereo inputs for either 2 CD players or 2 cassette players or combination of the two and
c) 6 - switches that can individually control the 6 - monochannels of the mixer (2 mono and 4 for the other 2 stereo channels) .
The project also includes :
- The appropriate explanations and specifications of each the different circuits of the audio mixer.
- A briefly eiplanation for the components used in the circuits, considering their use and their characteristics.
- The characteristics of the Ics used, their internal circuits, and some other applications that are given by the manufacturer.
- A complete testing of each of the 6 mono channels
- The needed connections that must be made to connect the audio mixer with the amplifier, the CD, the cassette players and the two different types of microphones.
It is almost certain that if someone reads this project will gain a lot of experience and information that are good to know. In the project there are more informations for the above mixer so someone can modify the above circuit and make it enable to control:
a) 2 - Pickups
b) 1 - cassette player
c) 1 - CD
d) 1 - tunner
e) 2 - microphones.
Also, detail circuits for ~
- a control pannel having Tone, Bass and Treble and
- a variable power supply are included, so that somebody in future, may construct a complete mixer and preamplifier, which it will approaches the professional standards of audio mixers.
