The figure presents a configuration that can be very useful for audio equipment designers. What this circuit does is obtain from an audio signal, two others that correspond to the original and the original with the inverted phase. These signals may be necessary for the excitation of output stages of bridge or counterphase amplifiers. Transistors are for general use and the intensity of the input signals must be in the range of 200 mV at 1 Vpp. For the output we have an intensity of signals of the same order.
