Stereo tone block five-band M266 Module

For comfortable listening to audio phonograms, it is necessary to change the sound timbre at certain frequencies. This is due to the acoustics, room parameters, individual taste of a person, etc. This equalizer is designed for this purpose, which allows you to smoothly change the frequency characteristic of the sound signal. Adjustment is carried out in five bands by dual potentiometers R7-R11. The equalizer is connected between the preamplifier and the power amplifier of the audio path. Two LA3600 microcircuits are used as active elements. The output of the equalizer should be connected to an amplifier with overall volume control.
