3 Band Tone Control Schematic

Audio tone control circuit can be used to set the tone of the bass tone 3 tone midle and treble tones.

3 band tone control schematic. There is no polarity of the thin film capacitors. Solder the components according to the schematic and part list. This is a 3 way tone control circuit. You may use the 7812 7912 dc regulator.

Notice the polarities of the electrolytic capacitors cp1 6. The system filters the tone used in auido 3 band tone control uses a system baxandal. 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. A 3 band tone control you can love.

The circuit shown in figure 7 1 originally came from a book of op amp circuits. 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. 3 band tone control circuit uses an op amp as an amplifier end. The electronic circuit has three separate adjustable filters.

All the capacitors that are associated with tubes are 200 volt. Apply dc voltage 15v and 15v to connector dc without plug in the. I did quite a lot of reengineering on it to make it tube friendly. Bass mid range treble stereo tone control circuit.

A good start is with c5 similar to c3 and c4 similar to c6 with c5 5x c4. It is based on the popular low noise ne5532 operational amplifier. 7 classic tone control circuit using 3 low noise transistors. This 3 band active tone control circuit uses a 12v dual power supply 80ma min.

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. This tone control circuit diagram of the home audio stereo is very well. Filter circuit is applied to the series of tone control 3 band this type baxandal like the title of this article. All resistors are 1 4 watt unless otherwise noted.

It low noise and sound is beautiful because use the quality transistor. Op amp tl072 is used for building and reinforcing the front end amplifier with symmetrical supply voltage 15 vdc and 15vdc. 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. Easy to build pcb small.

Audio circuit 3 band tone control is built using tl072 ic for each channel. Here is some of the math behind the circuit. It has positive negative ground. In picture we used three transistor number are c945 or c828 or c1815 or c458 they are old electronic components but useful now.

This is a very basic circuit diagram of 3 band tone control.
