3 Band Tone Control Schematic

All resistors are 1 4 watt unless otherwise noted.

3 band tone control schematic. The system filters the tone used in auido 3 band tone control uses a system baxandal. It can be used in any audio system and it is able to boost or attenuate the audio spectral content at low mid and high frequencies in the range of 16 to 16db. Audio circuit 3 band tone control is built using tl072 ic for each channel. Op amp tl072 is used for building and reinforcing the front end amplifier with symmetrical supply voltage 15 vdc and 15vdc.

Audio tone controls the mid band control parts values are established empirically as the math is complex and response is affected by the other 2 controls. Filter circuit is applied to the series of tone control 3 band this type baxandal like the title of this article. This is a 3 way tone control circuit. Solder the components according to the schematic and part list.

A good start is with c5 similar to c3 and c4 similar to c6 with c5 5x c4. This is a very basic circuit diagram of 3 band tone control. Notice the polarities of the electrolytic capacitors cp1 6. You may use the 7812 7912 dc regulator.

3 band tone control circuit uses an op amp as an amplifier end. A 3 band tone control you can love. I did quite a lot of reengineering on it to make it tube friendly. Audio tone control circuit can be used to set the tone of the bass tone 3 tone midle and treble tones.

Here is some of the math behind the circuit. The electronic circuit has three separate adjustable filters. Tone control circuit is a regulator of tone bass midrange and treble or 3 band called because it can set the three tones. Resistance value of resistor r1 is left up to the user depending on gain needs r2 is unknown for.

It is based on the popular low noise ne5532 operational amplifier. This 3 band active tone control circuit uses a 12v dual power supply 80ma min. 7 classic tone control circuit using 3 low noise transistors. The discussed bass treble tone controller circuit thus effectively performs like a 3 band graphic equalizer circuit allowing the user with distinct 3 way control of the sound frequency.

Bass mid range treble stereo tone control circuit. It has positive negative ground. There is no polarity of the thin film capacitors. This basic tone control circuit was originally intended for home audio use but should be able to be hacked into an effect circuit with very minor modification.

The bass control basically allows only the lower range of the frequency ideally between 10hz and 300hz that means the user can adjust this pot to cut off all. The circuit shown in figure 7 1 originally came from a book of op amp circuits. In picture we used three transistor number are c945 or c828 or c1815 or c458 they are old electronic components but useful now. This tone control circuit diagram of the home audio stereo is very well.

It low noise and sound is beautiful because use the quality transistor.
