Tone Control

Voltage-Controlled Tone/Volume/Balance Circuit

The LM1036 is a DC controlled tone (bass/treble), volume and balance circuit which can be applied in car radio, TV and audio systems. Loudness compensation to be simply effected is allowed by an additional control input. Control of the bass, treble, balance and volume function are provided by four control inputs through application of DC […]

Turbo Bass (Booster)

This is a Turbo Bass circuit. Using this circuit, the low frequency sound signals(bass) can be multiplied. This circuit is an active circuit. The first op-amp is used to buffer the audio input signal. The signal will be filtered by the second op-amp which will give bass signal output. Here is the schematic diagram of […]

Hi-Fi Tone Control with Transistors

Below is a cheap high fidelity (hi-fi) tone control circuit. This circuit has one channel (mono) control and we need to build another similar circuit to make it stereo. For better sound quality output, use good component (such as metalfilm resistors, MKM capacitors, tantalum capacitors, good cable quality) and stabilized power supply. The power supply, […]

High-Impedance Input Hi-Fi Tone Control

Tone control circuit is an electronic circuit which is designed to manipulate the tone of audio signal. Tone of audio signal is analog to color in light. We don’t call the tone of audio signal as red, green or or blue, but we can classify them as bass, mid, and treble. In general, tone control […]

Stereo Tone Control with LM1036

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, […]
