Circuit adjustable bass filter from 50 Hz to 150 Hz NE5532
This is a bass filter, using the OpAmp Ne5532 or another of your choice. The circuit is simple to set up and already has symmetrical power supply, supply, the transformer transformer must must use 9!2 "olts # 5$$ma with center tap % &n many cases the power source can be made by the power amplifier amplifier % % 'ust watch out for the limit supported by the "oltage regulators. The circuit has two pots, one for "olume ad(ustment and another to ad(ust the filter cutoff fre)uency of 5$ to !5$*+, if you need to install the pots in a panel, use shielded wires to mae connections.
