3 Input Mic Mixer Circuit


3 Input Mic Mixer Circuit - description here is a simple 3 input mic mixer circuit using the popular ua 741 ics four 741s are used here ic1 ic2 ic3 are used as pre lifiers they produce a gain of around 40 decibel to the individual input signals the ic4 is wired as a summing lifier to add the signals from three pre lifiers ic4 also gives a gain of around here is a simple 3 input mic mixer circuit using the popular ua 741 ics four 741s are used here ic1 ic2 ic3 are used as pre lifiers they produce a gain of around 40 decibel to the individual input signals the ic4 is wired as a summing lifier to add the signals from three pre lifiers ic4 also gives a gain of around 5decibel to the description here is a simple 3 input mic mixer circuit using the popular ua 741 ics four 741s are used here ic1 ic2 ic3 are used as pre lifiers they produce a gain of around 40 decibel to the individual input signals the ic4 is wire diagram.

1 0 shows the 3 channel sound mixer circuit using three norton op s 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 audio mixer by ic lf353 3 ch mic pre lifier with mixer using lm348 if you are looking for a mixer with a microphone and can easily make your own i highly re mend this circuit it is a microphone pre lifier for 3 channel or 3 channel mixer itself this is the very simple 3 input mixer for your audio system you can add the number of input by adding some ponents for mixer input p 10k r 22k this circuit is only re mend for low and intermediate audio sound system you need better mixer circuit for your high class audio system here the schematic diagram schematic to wiring diagram check for 3 mic mixer circuit using tl081 ask question asked 3 years 9 months.

ago active 3 years 9 months ago viewed 2k times 0 begingroup need a bit of munity validation to see that mapping of the following circuit schematic to this hand drawn wiring diagram seems correct and there are no obvious mistakes also does having 2 or 3 inputs instead of circuit notes the mixer circuit above has 3 line inputs and 3 mic inputs the mic inputs are suitable for low impedance 200 1000r dynamic microphones an ecm or condenser mic can also be used but must have bias applied via a series resistor as with any mixer circuit a slight loss is always introduced the final summing lifier has a gain circuit notes the mixer circuit above has 3 line inputs and 3 mic inputs the mic inputs are suitable for low impedance 200 1000r dynamic microphones an ecm or condenser mic can also be used but must have bias applied via a series resistor as with any mixer circuit a slight loss is always.

introduced the final summing lifier has a gain
