Matt circuit

This volume controller equalizer electronic project is designed using LM1036 DC tone volume controller with volume and balance circuit for stereo applications .An additional control input of the LM1036 allows loudness compensation to be simply effected. Volume Controller Equalizer Circuit diagram The four control inputs of the LM1036 volume controller provides control of the bass, treble, balance and volume functions through application of DC voltages from a remote control system or, alternatively, from four potentiometers which may be biased from a zenner regulated supply provided on the circuit.Each tone response is defined by a single capacitor chosen to give the desired characteristic.

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]. visit page. 5 Band Graphic Equalizer Circuit

This circuit is a five-band graphic equalizer mono, covering the audio frequency of 55Hz, 270Hz, 1kHz, 3.5 kHz and 12kHz. The basic difference between this graphic equalizer with other circuits, is instead of CI it uses transistors, the power supply is also special is +24 V 0-24v DC, this ensures low distortion and greater margins overload.   Simple 5 Band Graphic Equalizer Circuit Diagram List of components R1-4-37 = 330Kohms R2-7 = 2.2Kohms R3 = 120Kohms R5-6 = 6.8Kohms R8 to 12 = 1.8KOHMS R13 to 15 = 200Kohms R16 = 180Kohms R17 = 150Kohms R18 = 1.5KOHMS R19 to 22 = 1Kohms R23 to 27 = 220Kohms R28 to 32 = 15Kohms R33 = 10Kohms R34 = 15Mohm R35-38 = 220 ohms 1W R36 = 100 ohms C1-3 = 40V 1uF C2 = 68PF 100V C4 = 220uF 63V C5 = 1uF 100V C6 = 220nF 100V C7 = 47nF 100V C8 = 15NF 100V C9 = 5.6nF 100V C10 = 47nF 100V C11 = 15NF 100V C12 = 4.7nF 100V C13 = 1.5nF 100V C14 = 470pF 100V C15 = 68PF 100V C16-19 = 100nF 100V C17-20 = 470uF 40V C18 = 4.7uF 63V RV1 until RV5 = 50Kohms Lin.
