Balanced line with low supply

look up the tl072 datasheet. It will show the range of supply voltages.

Even if the tl072 works with +-5V, this will seriously limit the maximum signal throughput.

The impedance seen by the source on Hot and Cold are not the same. This needs a buffer to give identical impedances for both Hot and Cold.

Use three opamps in instrumentation topology or use a balanced line receiver.

The tl072 does not like driving the capacitance of cables. Choose a better line driving opamp.
