Amp Tone circuit | Next Electronics

Based on the classic Baxendall tone control circuit, this provides a maximum cut and boost of around 10dB at 10KHz and 50Hz. As the controls are passive, the first transistor, Q1, is configured as common-collector to act as a buffer...

3 band equalizer

A classic three-way tone control circuit that allows for the regulation of low, mid, and high frequencies of an acoustic signal. The boost/cut can be adjusted within a range of ± 18 dB/oct. The circuit operates on a supply voltage...

Amplifier circuit

An amplifier is a device that accepts a varying input signal and produces an output signal that varies in the same way as the input but has a larger amplitude. The input signal may be a current, voltage, mechanical motion,...
