In every audio mixer schematic that I have found, the signal circuit is described extensively. Here are a few examples: However, these diagrams do not show any considerations for the ground connections or isolation for the input''s grounds.
· The full output of the mixer circuit is Vout = Rf (V1/R1 + V2/R2 + V3/R3... + Vn/Rn). Thus, by making RF larger the gain can be increased. The other option is to make the resistor in the channel (s) smaller, but you are already using a potentiometer that can become very small, thus increasing the size of Rf is a better choice.
Audio mixer circuit diagrams. FET Audio Mixer December 3, 2010. This simple circuit mixes two or more channels into one channel (eg. stereo into mono). The circuit can mix as many or as few channels as you like and consumes very little power. Stereo to Mono Converter Based on FET October 3, 2010. This simple circuit mixes two or more channels into one channel ( stereo into mono). The ...
· Simple FET Audio Mixer Circuit Incircuit a FET number 2N3819 is main, it is better than common transistors that a high impedance input and high gain too. so cause low noise. It can increase the number of channels too, By adding a VR1, R1, and C1 to the amount needed. Then connected to Buffett a new one.
The circuit is much smaller than a real inductor (at least for the larger values), and does not suffer from noise pickup. It does have a limited Q (quality factor), but it is rare that very high Q circuits are needed in audio, so this is not really a problem. It is also variable over a .
4 Channel Portable Audio Mixer Highquality modular design, 9V Battery powered Very low current drawing The target of this project was the design of a small portable mixer supplied by a 9V PP3 battery, keeping high quality performance. The mixer is formed assembling three main modules that can be varied in number and/or disposition to suit everyone needs. The three main modules are: Input ...
Audio mixer circuit is work as the current adding circuit. Improved Audio Mixture Circuit. An improved transistor audio mixer circuit is given in figure 2. Here each input is fed to a separate transistor. Bootstrapping ensure a high input impedance more than 1 M. All the input transistors share a common collector to load resistor. The following emitter – follower stage ensure a low output ...
Mixer serves as a mixing sound, a mixing console, whether it is analog or digital, or also called a soundboard / mixing desk (soundboard) is an electronic device that functions blends (more popular with the term "mixing"), setting a path (routing) and change the level, as well as the harmonization of the dynamic of the audio signal. Signal the signal that has been modified and set later ...
Generally audio mixing process is carried out by the mixing engineer. Currently artists and engineers are using PC (personal computer) for audio mixing. This article describes you how to design a multi channel audio mixer using lm3900 quad amplifier. This audio mixing circuit has 2 MIC inputs and 2 line inputs. If you want to increase the input ...
Making an Audio Mixer: This simple passive DIY stereo audio mixer demonstrates resistors in use. When I say stereo, I am not talking about your home entertainment signal, but an audio track with a separate left and right mixer will allow us to combine two ste.
This audio mixer circuit requires Regulated DC power supply and audio signals can be directly given as input or can be given after preamplification. Provide common ground (Gnd) for all non inverting inputs. Instead of Variable resistors we can use sliding adjustable potentiometer to make the circuit more professional. Related Posts .

The input audio signal inputs are where the audio signals which are to mixed enter the circuit. This could anything from microphone input, to a music audio file, to a speech file, any type of audio input which can be connected to this mixer. The 1µF capacitors which are directly after the audio signal inputs are coupling capacitors. These ...
A simple multichannel audio mixer circuit using LM3900 quad amplifier is given below. The circuit consists of 4 channel quad amplifier (LM3900). Two mic audio inputs and two direct line inputs are available in this circuit. By adding the same circuit parallel with this, you can increase the number of inputs according to the applications.

The circuit is an audio mixer circuit so simple as it can be. There are two dual logarithmic potentiometers in the circuit to adjust the input signal levels and some resistors to do the actual mixing. The circuit is totally passive, so no power supply is needed.
This circuit is actually really simple. All the complexity is due to repetition. Basically, all circuits are as follows: input > output For an audio mixer, you need a resistor on each input. So, we have: input > resistor > output But, it''s stereo so you have to do everything twice. So, now you have: L input > resistor > L output R input > resistor > R output You could stop here ...
· The circuit is a simple two transistor preamplifier using a feedback loop for enhancing the amplification. Any music as we know is in the form of a consistently varying frequency, therefore when such a varying input is applied across the indicated C1 end terminals, the same is delivered across the base T1 and ground.
anonymous: FET Audio Mixer: Saturday, January 20, 2018 6:56:27 AM: Neat little circuit. To better understand the circuit you need to know the 2N3819 FET operates in "depletion" mode which means current flows between source and drain when the gate is at 0 volts.
· VU CIRCUIT. The VU meter circuit utilized in the mixer board is quite fundamental, yet well suited for several similar audio level indicator purposes, distortion presented into the output signal can be as much as 2% THD, therefore we highly recommend the VU board.

· This audio mixer circuit uses an LM3900 IC but is not a profesional audio dj mixer. The IC houses four integrated Norton amplifiers. The advantage of using the four op amps is that they only need a single power supply. Since this amplifier circuit is current controlled, the DC bias is dependent on the feedback coupling.
