The main component used here in the circuit is the transistor, It will intelligently divide the sound signal to a source.It has three variable resistors for controlling the input sound signal. The signal is then fed to the ceramic capacitors that would block any DC voltage and only allow the signal to pass through the line. The ceramic capacitor is very useful as …

In this tutorial, we are going to make an "LM3900 Audio Mixer Circuit". An audio mixer circuit is used to combine output from several microphones/channels into one or more common outputs. Often, you'll find audio mixers in either digital or analog form.
Understanding the Passive Mixer Schematic. In audio systems, mixers are used to combine multiple audio signals into a single output. A passive mixer is a type of mixer that does not require external power for operation. Instead, it relies on passive components such as resistors, capacitors, and sometimes transformers to perform the mixing function.
