Home > Circuits > A > Audio Mixer Circuits: Audio Schematics Mixer Circuits: 2 Line Output biner Convert consumer equipment stereo signal to mono or combine audio signal from two different equipments to1 input . 3 Line Mixer. 6 Input Mixer (mitedu) The mixer circuit below has 3 line inputs and 3 mic inputs. The mic inputs are suitable for low impedance 200 1000R dynamic microphones. Mic Audio Mixer Circuit Audio Circuits Mic Audio Mixer Circuit Notes: R1 R3 are volume level control on each input. R9 and R11 will control bass and treble for all input. The circuit only need low current to run, two 9V batteries which connected in parallel can be used for a power supply. The placement of the mixer in a metal case and connected the ground to the case will cut down ... Audio Mixer with Multiple Controls | Full Circuit Diagram ... Audio mixer circuit. Fig. 1 shows the block diagram of the audio mixing system along with the audio power amplifier, while the circuit of the audio mixer along with a tone controller is shown in Fig. 2. The power supply and audio power amplifier circuits are shown in Figs 3 and 4, respectively. Simple Microphone (MIC) Amplifier Circuits 5 Input Microphone Mixer Amplifier Circuit using a Single IC This circuit enables the user to blend in one 5 separate signals from 5 dynamic low impedance microphones and a couple of external auxiliary inputs, which can be electret type microphones or even actually amplified inputs for example those from your CD player or a phone. Mixer Category Electronic Circuit Diagram This is an active stereo tone control circuit using very well known op amp IC of TL072. The circuit include mic pre amp and mixer control. In this design, we have two inputs: one for line (stereo), one for microphone and has control of the three audio frequency (high treble, medium and low bass). How to build an audio mixer circuitlib The circuit of figure 3 is a good example of an input module of a mixer. Of, course there are many other circuits for the same purpose. Any voltage preamplifier which has adequate input impedance and has also a volume level adjuster can be used at the input stages of a mixer. Actually, there are some additional criteria for the right candidate. Mixer Category Electronic Circuit Diagram This is an audio mixer circuit which designed along with VU meter circuit. The circuit is for one channel input, if you need, for example 5 channel mixer, then you need to build 5 similar circuits. The this audio mixer uses three potensiometers to adjust volume level, low frequency (bass) level and high frequency (treble)… Read More » 3 Channel Audio Mixer Circuit electroschematics Diagram 1.0 shows the 3 channel sound mixer circuit using three Norton opamps. The input levels can be set by potentiometers P1 or P3. Furthermore, each input level can be trimmed with the help of trimmers pots P4 to P6 to adapt each input to the source. Microphone Circuits Electronics Tutorial and Schematics ... Microphone Circuits and Tutorials Balanced Low Noise Microphone Preamp: very low noise, close to the theoretical minimum, high hum rejection and variable gain with a single rotary pot, similar to that used in many professional grade mixing desks ... Send signal from1 microph1 to two mixers, product datasheet with circuit diagram in PDF format ... 4 Channel Portable Audio Mixer Circuit Diagram 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 Amplifier Module: a low noise circuit equipped with a variable voltage gain (10 100) preset, primarily intended as high quality microphone input, also suitable for low level line input. 3 Simple Audio Mixer Circuits diagram | ElecCircuit Audio Mixer by IC LF353. 3 CH MIC preamplifier with Mixer using LM348. If you are looking for a mixer with a microphone, and can easily make your own.I highly recommend this circuit.It is a microphone pre amplifier for 3 channel or 3 channel mixer itself. When looking at the circuit, we have featured the use of a single integrated circuit LM348. 2 Channel Mic Mixer Circuit Diagram Circuits99 2 Channel Mic Mixer Circuit Diagram. However, this 2 Channel Mic Mixer Circuit Diagram better the transistor quality better the performance. C1 and C2 perform the job of input coupling and DC isolation while C4 is the output DC decoupling capacitor.
