Creating LPF circuit for rear fill decode schematic

Need a little help getting this schematic figured out, most of it is understood with the exception of the triangular objects(amps-opamps?)

Not sure what those are or how to implement and order them. Here is the diagram thus far(planning to test with a lpf at 1k and 500, with the hpf staying around 80-100hz)

Thank you for any help.

 
The triangle things are opamps, any generic part would do. But the circuit assumes a split +/- power supply which you don't have. It's also much simplified and not detailed enough to be practical. A real circuit would have bypass caps on the power supplies and a coupling cap at the input etc.
