3 Tone control circuits using op amp NE5532

Today, I recommend a bass mid treble Tone control circuit using an op-amp. They include 3 circuits. We choose to use the NE5532 as main, it is so an interesting IC. Because of the ultra-low noise properties.

So often uses them in a Hi-Fi audio system. But these circuits are old. They have been a small circuit with PCB layout.

There are 3 circuits below.

I hope they will be useful to you. Good luck, thanks.

Circuit #1: Pre Tone Control Stereo using NE5532

First circuit diagram. If you want a good simple Pre Tone Control circuit in Stereo. I recommend this circuit in your choice.

Because it uses only one NE5532. It is a high-quality IC, inexpensive extremely.

Look at the circuit.

Although, it is a small stereo(2 channel) circuit. But it has a full option to adjust the sound.

In this circuit, you can adjust the bass, treble sound well, and high-low sound in easy.

Also, set a balance of the sound everything is completed.

You may use your skill to try to build the circuit in easy with PCB layout Below.

Look below.

What is more?

Sometime you may want more adjusting.

Read NE5532 datasheet and pinout

Circuit# 2: Bass-Mid range-Treble Pre Tone Control

If you do not like the first circuit. Because it cannot adjust all full range of sound.

This is the second circuit. It still fully adjusting to Pre Tone Control in Stereo.

You adjustable Bass, midrange and treble.

So, you can adjust full-range sound easily.

Note: This 3 band active tone control circuit uses a 12V Dual Power Supply, 80mA min. It has Positive, Negative, Ground. You may use the 7812-7912 DC regulator.

Easy to build, PCB small.

Circuit# 3: High Gain Stereo Tone Control  (bass-treble) using NE5532 x2

If you do not like the first circuit. Because it may low power output so cannot really use with a very small input signal.

High gain pre tone control stereo using NE5532

My friends want a tone Control Stereo circuit.  It can control the sound bass-treble-volume well. And it is a high gain more than two circuits above.

Then, I found this circuit, Tone Control Stereo (bass-treble) using two NE5532.

Also, it uses an integrated circuit op-amp that is low many noises or low noise. So, it makes a good sound and easy to build too.

This circuit uses two integrated circuits.  So it can amplify a smaller signal input to a power amplifier.


You should use a good quality of DC dual regulator power supply,+12V and -12V.  Such as use IC LM7812- LM7912, etc.

Besides, IC1 and IC2 use, the number can replace many the number such as NE5532 or LF353 or RC4558, etc.

For convenience to friends.

You can see a model PCB layout. Have fun building Tone Control Stereo (bass-treble) using NE5532 in the link below.
