A classic circuit of regulation of tone of three way, with which
we can regulate low, mid and high frequencies, of acoustic signal. The boost/cut can be
regulated in the range of � 18 dB/oct. In the circuit the supply is � 15V, but can be
also supplied with alone supply + 9 until + 30V, it is enough it is connected pin the 4
IC1, in the 0V and is connected the circuit with as it appears in fig. 2, giving half the
supply in the not inverting entry of IC1, in the 5 and 3 equivalents, which are henceforth
not connected in the ground.
