This circuit has one channel mono control and we need to build another similar circuit to make it stereo. This op amp ic has 4 operational amplifiers but in this circuit only 2 op amps are used.
Simple Tone Control Red Page172
Hi fi tone control circuit diagram. You can make this and fix this for your homemade audio player speaker. The use of these simple circuits is normally restricted to guitar applications or inexpensive radios. This is a inexpensive high fidelity hi fi tone control circuit designed just with two low cost transistors as the active components. 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. For better sound quality output use good component such as metalfilm resistors mkm capacitors tantalum capacitors good cable quality and stabilized power supply.
The circuit is designed to adjust a smooth bass and treble is soft sound with very low distortion. This is must before audio level controller. As application of this tone controller circuit it. 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. In hi fi amplifiers tone control refers to the boosting or reduction of particular audio frequencies. Because it uses all low noise transistors.
The schematic is one channel mono tone control build the similar circuit will make it become stereo channel. In picture we used three transistor number are c945 or c828 or c1815 or c458 they are old electronic components but useful now. Here is two tone control circuit diagram which can be used to make a tone control at home easily. Turbo bass circuit bass booster circuit diagram this bass booster circuit is made using the quad op amp ic lm324. The schematic is one channel mono tone control build the similar circuit will make it become stereo channel. As the circuit only reduces the high frequency content of the signal it could be called a simple treble cut control.
This hi fi tone control circuit can be operated with wide range supply voltage 12v 24v dc. The schematic is one channel mono tone control build the similar circuit will make it become stereo channel. 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. Two 100k variable resistor is used in both circuit. The 1st circuit used an op amp ic 741 some pf capacitors and some resistors. If you are looking for a hi fi audio tone control circuit.
Classic tone control circuit using 3 low noise transistors. This may be the best choice for you. This circuit provides low pass filter of input audio which produces a low frequency of input and high frequency is blocked. Below is a cheap high fidelity hi fi tone control circuit. This tone control circuit diagram of the home audio stereo is very well. This hi fi tone control circuit can be operated with wide range supply voltage 12v 24v read more.
It low noise and sound is beautiful because use the quality transistor.
