If your audio output is in mono, then here is the perfect way to do mono audio signals to stereo using simple converter circuit. The better performance you can achieve through this circuit.
Working
The above designed mono to stereo audio signal converter schematics working with best op amp IC of NE5532. A single IC is enough to build this circuit. The circuit will give maximum efficiency of audio signals of Left and Right channels. The circuit needs a dual power supply voltage of 15-0-15 DC that not mentioned in the circuit diagram.
The 10K potentiometer is set for the effect change in the output section of left and right channels, You can turn it by left side or right side to feel the audio effect. Set the potentiometer at your choice of hearing level. The left channel and the right channel section will looks like same, because the mono channel produce only mono signals through it. while turning the potentiometer will make some effects like normal stereo.
Components required
- Ne5532 IC
- 10K potentiometer
- 4.7K resistor instead of 4.87K
- 2K resistor
- 12K resistor
- 39pf Capacitor
