This circuit is for graphic equalizer that can build with low components count and control using LA3600 single IC chip. The internal design of the chip uses transistors gyrator circuit, with connections to external capacitors to set the response. This is the figure of the circuit. Sorry, this picture is not clear. This graphic equalizer circuit is suitable for tape-recorders, radio-cassette recorders, car stereos, or home theater sound systems. Maximum supply voltage VCC max 20V must not be exceeded. The operating voltage is in the range of 5 to 15V. [Schematic diagram source: SANYO Electric`s Application Notes].
