SPICE simulation of a low noise balanced microphone preamplifier, the input stage consists of differential pairs of transistors 2N4403 and BC549, a common mode gain control connects the emitters of the pairs. A differential operational amplifier implemented with a TL071 provides a balanced to unbalanced buffer because the circuit is differential in and out.
