3 Band Tone Control Schematic

A good start is with c5 similar to c3 and c4 similar to c6 with c5 5x c4.

3 band tone control schematic. A 3 band tone control you can love. Audio tone control circuit can be used to set the tone of the bass tone 3 tone midle and treble tones. 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. 7 classic tone control circuit using 3 low noise transistors.

Solder the components according to the schematic and part list. There is no polarity of the thin film capacitors. Easy to build pcb small. The electronic circuit has three separate adjustable filters.

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. This 3 band active tone control circuit uses a 12v dual power supply 80ma min. In picture we used three transistor number are c945 or c828 or c1815 or c458 they are old electronic components but useful now. Filter circuit is applied to the series of tone control 3 band this type baxandal like the title of this article.

Apply dc voltage 15v and 15v to connector dc without plug in the. Bass mid range treble stereo tone control circuit. Op amp tl072 is used for building and reinforcing the front end amplifier with symmetrical supply voltage 15 vdc and 15vdc. 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.

This is a very basic circuit diagram of 3 band tone control. This is a 3 way tone control circuit. It is based on the popular low noise ne5532 operational amplifier. It low noise and sound is beautiful because use the quality transistor.

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. All the capacitors that are associated with tubes are 200 volt. Resistance value of resistor r1 is left up to the user depending on gain needs r2 is unknown for. The system filters the tone used in auido 3 band tone control uses a system baxandal.

The circuit shown in figure 7 1 originally came from a book of op amp circuits. Here is some of the math behind the circuit. It has positive negative ground. Notice the polarities of the electrolytic capacitors cp1 6.

Tone control circuit is a regulator of tone bass midrange and treble or 3 band called because it can set the three tones. I did quite a lot of reengineering on it to make it tube friendly. All resistors are 1 4 watt unless otherwise noted. You may use the 7812 7912 dc regulator.

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.
