Passive mixer schematic
WebJul 24, 2024 · The 3 pots and R4, R5 & R6 form a passive mixer, without going into any nasty mathematics the output of the passive mixer at the positive input of U1a is the sum of the three inputs divided by 3. The opamps U1a is a non inverting amplifier with a gain of 3, making up the losses in the passive mixer. Any other questions about it, please ask. WebThe input signal from the passive, high-pass filter is connected to the IC’s non-inverting input pin (pin 3). A 22 kilo-ohm resistor (“R5” in the circuit diagram) is connected between the IC’s pins 6 and 2, providing negative feedback. The inverting pin (pin 2) is grounded via a 2.2 kilo-ohm resistor (“R3”).
