You should recognise the circuit based around U1A - it's the standard single opamp balanced input circuit (but it is drawn differently). The circuit has a gain of two, so the input voltage is divided by two at the non-inverting opamp input, ensuring that the output signal is the same amplitude (and phase) as the input signal.

Figure 1 represents a typical balanced audio-transmission system with a line-driver circuit that transmits two complementary audio signals (V S and –V S) over a shielded twisted-pair cable to a line receiver. R S1 and R S2 represent the output impedances of the line driver. Figure 1 also shows a line receiver where R IN1 and R IN2 represent the input impedances.
