Tone Control

Transistor stereo bass booster

This is a bass booster that use transistors as base. It is designed to increase a low frequency of audio on cheaper than ICs or normally circuit. since use each channel only 2 transistors together with resistor and capacitors approximately ten parts only. In circuit will be have a potentiometer trimmer 10-50K act as adjusted […]


Three circuits of preamp tone controls by NE5532

Today, I recommend a good quality preamp tone controls, a total of three circuits. We choose to use the NE5532 is main so interesting IC, because the ultra-low noise properties, it is commonly used in many fine audio. But these circuits are old. I have a circuits of friends. They has been small circuit with […]

The super pre tone control project can build by yourself.

I always recommend relatively many circuits or project on the pre tone control. Today we see other interesting project. (Please do not get bored them). we can divide normally type of the tone control are 2 types as following 1. Passsive Tone Control 2. Active Tone Control A stype of the passive tone control circuit […]

Simple Passive tone control circuit

The Passive tone control circuit be the circuit fines the bass that has no the expansion but will give kind equipment R and C. It perform filter frequency then the circuit that build easy and must not use power supply. By can concede the porch with part power amplifier of output immediately. When feed input […]

5 Channels Graphic Equalizer by LA3600

This circuit 5 Channels 2 Octave Graphic Equaliser,easy to make equalizer, because using IC LA3600 (easy to use) For you who take an interest sound of music side may nobody strange Graphic Equalizer circuit , but , in you who are a novice , something will build this some group circuit gets into trouble moderately […]

Stereo Tone Control with LM1036 circuit diagram

This is a stereo audio tone control circuit which build based on IC  LM1036. This circuit will controll bass/treble level tone, volume and balance between right channel and left channel (input 1 and 2 ). You may use this circuit for stereo applications such as car radio, TV and audio systems, mp3 player, dvd player, […]


Hi-Fi Tone Control circuit diagram

This 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. Use good component (such as metalfilm resistors, MKM capacitors, tantalum capacitors, good cable quality) and stabilized power supply for better sound quality output.The quality of component, cabling and […]

Tone Booster circuit diagram

Below circuit is the tone booster circuit. According to the name of circuit, the purpose is to gain the sound signal to become more powerful in both low and high frequencies. Transistor type: Q1 – ztx384 ; Q2 – BC415pThe circuit’s peaks frequencies is at 5000 Hz for a cleaner and more penetrating sound.Download Tone […]

Basic Tone Control circuit diagram

This is a very basic circuit diagram of 3 band tone control. This circuit was originally intended for home audio use, but should be able to be hacked into an effect circuit with very minor modification. Resistance value of resistor R1 is left up to the user depending on gain needs, R2 is unknown – […]
