2020-5-7An audio mixer also called a mixing console is an electronic device for combining and modifying audio signals.The modified audio signals are summed to produce some combined output signals. Audio mixers can be analog or digital type. Digital mixing consoles use Digital Signal Processing concepts and analog mixers are usually based on op-amps electronic circuits

This article discusses about the design of a simple audio mixer circuit. An op-amp based summing amplifier is used here to mix two sounds. The audio mixing is demonstrated with the help of mixing a high frequency musical sound with a low frequency bass beat where the musical sound is generated by a musical IC and the bass beat played at a mobile phone and is captured and amplified through a

Another audio mixer circuit using the LM349 is given in circuit 4. Here each input is fed to a separate op-amp the input is given to the inverting input of op-amp through its own input resistor as shown in circuit diagram. After suitable buffering and amplification they are mixed by the last op-amp N 4. The output is taken from pin 14

Lets start designing our circuit for the mixer. For your party you want to have 4 singers and 1 song mixed together. This is a total of 5 channels so you will need 1 op-amp and 5 potentiometers. An op-amp is not well suited to directly driving a speaker so a power amp is normally included to drive the speaker

Op amp summing amplifier Based around the inverting amplifier circuit with its virtual earth summing point this circuit is ideal for summing audio inputs. It is widely used in audio mixer and many other applications where voltages need to be summed. When used in radio mixer applications this operational amplifier circuit is ideal because the virtual earth summing point results in the

In this circuit we will show how to build an summing op amp circuit using an LM358 dual operational amplifier chip. A summing circuit is a circuit that performs the mathematical operation of addition. It adds up all the voltages that are input to the op amp. In this circuit we use 3 inputs so it adds up all 3 inputs into the op amp

Unlike traditional op-amp that respond to differential voltages LM3900 utilies the differential current. The operation of the circuit is simple. The input side is composed of two audio mic inputs and two direct lines. Audio input is being amplified separately and it is connected in the inverting side - of each op-amp

2016-2-22Audio Mixer. The circuit schematic below represents one method for the design on an audio mixer. The active component is an LM318 although basically any operational amplifier would work in its place. The circuit is the classic design for an Op Amp summing amplifier. Four individual audio channels are shown and may be mixed together

2020-3-15I am using an NE5532 as a voltage followerbuffer in an audio circuit and am having some noise issues. Ive simplified the circuit to isolate the issue. The audio input signal comes in through an audio transformer to the IN on the amp. The amp output is currently going directly into a commercial mixer for testing
