The two op amps are used as comparators to indicate the excess amount of the AP signal , whether positive or negative, even if the signal is asymmetric. P1 sets the reference voltage for the two operational amplifiers. This circuit uses a split power supply, which is useful for audio amplifier and op amp circuits.
