Active xo question

Just a quick one, looking at this balanced input circuit

Balanced Input

leading to an active crossover, if i wanted to add an un-balanced input, could i just input it directly at the output of the first op amp (would also be unbalanced line out from the balanced line in?) or should it have another input op amp, connected to the same place (before the 10k to the second opamp)

Cheers for your help.

For unbalanced operation just use one of the inputs and ground the other. You don't need to modify or add any additional circuitry.
