Overview of the Audio Mixer
I. Introduction. Audio mixer, also called mixing console, is an electronic device for combining (also called "mixing") and modifying audio signals. Audio mixers can be analog or digital type. Digital audio mixer use digital signal processing and analog mixers are usually based on operational amplifiers (opamps) electronic circuits.

Modular Audio Mixer with Multiple Input Channels
The mixer circuit consists of 6 channels with monophonic channels from 1-4 while stereo channels for 5-6. The number of input channels can be varied while choosing between mono and stereo channels. The potentiometer RV1-6 regulates the sound level and drives each channel. The balancing between two channels is achieved by RV7-12.

The Basics of Mixers | DigiKey
There are three basic types of active and passive mixers: unbalanced, single-balanced, and double-balanced. Conversion loss or gain: Measured in dB, conversion gain measures the signal gain in an active mixer, while conversion loss (known also as CL) measures the insertion loss in a passive mixer. Conversion gain is defined as the ratio of …

1) The 22 pF capacitors improve stability. A mixer sometimes drives a fairly long cable, which appears as a capacitive load, which can cause opamps to oscillate. So the 22 pF capacitors improve phase margin. They also reduce gain at high frequencies (well above the audio band) which can help in electrically noisy environments (radio ...

10K Audio Passive Summing circuit
In response to comment: There are two ways to build a passive splitter/combiner. One way is to use multiple coils on a single audio transformer core. The other way uses resistors. The datasheet specifies that the STD-10K uses a resistor network to combine the signals. This guy built a resistor network combiner/splitter himself.

An audio mixer is an electronics instrument that accepts a large number of signals. Through a small space and keeps them strictly apart until the operator chooses to mix them. A well design audio mixer accepts all the signals to its input and reproduces them at its output where all the signals are heard without distortion or interference.

Model mixer in RF systems
This mixing converts the frequency of RF signal to ω RF + ω LO and ω RF – ω LO.For the mixer to perform this operation correctly, you must include the frequencies ω RF + ω LO or ω RF – ω LO in the simulation frequencies the Configuration block calculates. The Power gain specification for this block relates the power of a single-sideband (SSB) to the input.
