Two 100k variable resistor is used in both circuit. To operate the circuit connect the components as per the circuit diagram give 15v and 15v supply to tl072 opamp and give audio input from mobile by connecting 35 mm audio jack to the circuit.
Low Noise Pre Tone Control Circuit Using 4558 Ne55532
Hi fi tone control circuit diagram. This circuit has one channel mono control and we need to build another similar circuit to make it stereo. The schematic is one channel mono tone control build the similar circuit will make it become stereo channel. For better sound quality output use good component such as metalfilm resistors mkm capacitors tantalum capacitors good cable quality and stabilized power supply. Here is two tone control circuit diagram which can be used to make a tone control at home easily. This hi fi tone control circuit can be operated with wide range supply voltage 12v 24v dc. You can make this and fix this for your homemade audio player speaker.
Below is a cheap high fidelity hi fi tone control circuit. The schematic is one channel mono tone control build the similar circuit will make it become stereo channel. Turbo bass circuit bass booster circuit diagram this bass booster circuit is made using the quad op amp ic lm324. As application of this tone controller circuit it. The circuit is designed to adjust a smooth bass and treble is soft sound with very low distortion. This hi fi tone control circuit can be operated with wide range supply voltage 12v 24v read more.
Classic tone control circuit using 3 low noise transistors. This is must before audio level controller. This is a inexpensive high fidelity hi fi tone control circuit designed just with two low cost transistors as the active components. Hi fi tone control this is a inexpensive high fidelity hi fi tone control circuit designed just with two low cost transistors as the active components. The use of these simple circuits is normally restricted to guitar applications or inexpensive radios. This tone control circuit diagram of the home audio stereo is very well.
In hi fi amplifiers tone control refers to the boosting or reduction of particular audio frequencies. The 1st circuit used an op amp ic 741 some pf capacitors and some resistors. It low noise and sound is beautiful because use the quality transistor. As the circuit only reduces the high frequency content of the signal it could be called a simple treble cut control. In picture we used three transistor number are c945 or c828 or c1815 or c458 they are old electronic components but useful now. This may be the best choice for you.
The schematic is one channel mono tone control build the similar circuit will make it become stereo channel. If you are looking for a hi fi audio tone control circuit. This op amp ic has 4 operational amplifiers but in this circuit only 2 op amps are used. This circuit provides low pass filter of input audio which produces a low frequency of input and high frequency is blocked. Because it uses all low noise transistors. Now you can control the bass treble and volume by rotating three potentiometer on the circuit.
This is a inexpensive high fidelity hi fi tone control circuit designed just with two low cost transistors as the active components.
