| 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. The mixer is shown with two inputs, but you can add as many as you want by just duplicating the "sections" which are clearly visible on the schematic. |

| hello thanks for the circuit schematic. can anybody mention any other fet's that could be used instead of the 2n3819. in fact, anything about transistor equivalencies (specially for mixer purposes) is welcomed,thank you | ||
| This mixer attenuates the input levels. With 2 inputs the levels are half. With 4 inputs the levels are 1/4. With 8 inputs the levels are 1/8th etc. | ||
| can anybody tell me more about the description of the circuit any one plz.... and yes i woul dalso like ot know that how are you goin to provide the input and output ? any specifications? any about the frequency ? amplitude (voltage) minimum or maximum requirements... anything any info.. plz tell me.. and kindly plz .. if any can guide me on my e-mail | ||
| please i need a very powerfull mixer with 8 channel and that have bass, treble, and volume control. thanksmfor your support. | ||
| I'd like to built this. does anyone have a circuit diagram for PC board or Veroboard layout? Thanks | ||
| I'm pretty new at this game-- what other transistors could be uses as a substitute for the 2N3819? | ||
| Oops! I forgot something. If the blocking caps are put between the wipers and resistors, then the Gate of the FET must have a 1 meg resistor to ground. | ||
| The combination of the DC blocking capacitor C1, and the level control pot R1 make a high pass filter that causes frequencies below 159 Hz to roll off, so that the sound has a loss of bass frequencies. The problem is that C1 should be larger and/or R1 should be a higher value. I would increase the pots R1 and R3 and resistors R2 and R4 to ten times their values. Pots should be 100k, and resistors should be 1 meg. Notice that C1 doesn't have to be on the input. It could instead be between the pot wiper and R2. Also, C3 should be ten or more times larger, 1 uF or more. Connect the polarized cap with positive to S of the FET. | ||
| What type of diode would you suggest to place where exactly to avoid signal flow into each other? Also, I would like to know whether it would be possible to use a power supply of 12 V without blowing the FET. Do I have to change/remove R5 and/or C3? I am too poor in electronics to tell by myself and would appreciate your help very much. | ||
| FET AUDIO MIXER is really great when it comes to audio mixing it depends only to one who assembled this circuit.if you assembled it and it does not work then maybe the problem is with in you as the assembler of this fet audio mixer. if you have assembled the fet audio mixer the one with split supply its really incredibly good in performance. i say that because ive made it by myself. i mean its perfomance is superb. | ||
