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

Pre Tone Control Stereo using NE5532
First circuit diagram. If you want a good simple pre Tone Control Stereo. I recommend this circuit in your choice. Because it uses only one NE5532. It is a high-quality IC, inexpensive extremely.
Although it is a small stereo(2 channel) circuit. But it has 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.

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 Stereo. You adjustable Bass, midrange and treble. So you can adjust full range sound easily.
Bass-mid range-treble Stereo Tone Control circuit
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.

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.
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.
In this circuit uses two integrated circuits. So it can amplify a smaller signal input to a power amplifier.
Caution!
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 a link below.

1 Jun 2014Hi,
I am from Poland and I want to build pre tone control (3 bands) on NE5532. My question is: How will be work this preamp with IC TDA7560?

13 Jun 2014Hi.
I want to build this circuit, I want to use it together with a bass-guitar amp. My question is, the circuit looks like two circuits that results in two inputs and two outputs. If my output will be on only one speaker, do I need the two circuits coupled by the “balance potentiometer”, or can I just build one with one input and one output?

13 Jul 2014Hi All,
I want to make a stereo pre amplifier with bass ans treble control.
Have anyone made this circuits? please tell me which one is the best.
Thanks,

18 Aug 2014Hi.. I found this circuit is very useful..one thing I need to know can I use the first section only..i.e. the first opamp circuit before the baxandall tone control circuit as an audio preamplifier??
thanks in advance

30 Mar 2015Hi thanks for the circuits. I have a question for the schematic No.1
I have a hard time understanding the capacitor values.
0.47µF (electrolytic or ceramic)
0.033µF = 33nF
0.0033µF = 3.3nF

30 Mar 2015Hi sir
I am trying my best to understand your English.
Of course that is not so important.
Sir
I am planning to build a High quality, High Power( >= 300 watt(rms)) Amplifier.
I need a very high quality Pre-amp with Bass, Treble, Blance and Loudness control.
I also need a 10 band Graphic Equalizer.
Could you please suggest which Configuration is best.
1. Do you have ready made Pcb’s for all these. 2. If you have How much is the cost.
You can write it to my personal email ([email protected]). I want it to use it at home. I am fedup with all these so called Home theaters.
Regards
Sen

1 Jun 2015Hi, nice design, but can you please publish here what kind of capacitors each capacitor are in the circuit? if it is ceramic or polyester or electrolytic? and the capacitors are all express in microfarad right? tnx in advance! i want to build the 2nd design, which has a midrange.
