Automotivecircuits use two types of signals:â¢INPUT-provides information about operating conditions(switches, sensors)â¢OUTPUT-causes an electrical or electronic device to operate(lamps, LEDs, relays, motors)Input and output signals can be either digital or analog, depending onthe application.
(1) Analog mixers. Analog mixers adjust the volume and tone of input audio signals. Most of the control knobs and faders are arranged on the top panel, so it is easy to understand the signal flow and what state the audio is in.Operating analog mixers is normally an intuitive process.or example, when using a mixer with a band, at least eight channels for input may be required for microphones to pick up the sound of the whole drum kit. In this case, a model that is equipped with enough channels that are compatible with microphones should be chosen.
