![]() ![]() If you want to ignore my methodology and go your own way, that is your business. There will be no soap dishes with wires sticking out of them in this class. Not only that, I am going to show you how to build them well. In most of these projects throughout this class we will be starting with the enclosure. ![]() Typically enclosures are made as after thoughts for electronics projects. This is the simplest audio mixer you can make, but hardly the best one. Otherwise, any time lines intersect, they should be connected together. Also, notice the strange half-loop to the right of the 1K resistor that is third from top? That loop represents a 'hop' in the schematic and means not to connect those wires together. The triangles next to each jack represent a channel. The three boxes that look like strange renderings of potted flowers are actually audio jacks with their barrels connected to ground. This schematic shows the left channels and the right channels being connected together through resistors. You are left with a two channel stereo mixer. The right channels can be mixed in identical fashion. If you connect each respective left channels to a 1K resistor, and the other end of each resistor together, then you have effectively mixed the left channels together. The easiest way to do this is to combine them together using resistors. If we want to combine two stereo signals into one, we will need to mix together the left channel of each stereo signal, and the right channel of each signal. A stereo signal is two channels (left and right) which are actually two separate audio signals with a shared ground. ![]()
