Stereo Digital Volume Control

Here is the circuit diagram of stereo digital volume control. This circuit could possibly be applied for upgrading your manual volume management within a stereo amplifier circuit. In this particular circuit, push-to-on switch S1 controls the forward (volume enhance) operation of the two channels while a identical switch S2 controls reverse (volume reduce) operation of… Read More »

ACTOR : Active Tone Control

The following diagram is the schematic diagram of Active Tone Control circuit, or we often call this circuit as “ACTOR”. The circuit is quite simple, easy build and inexpensive, you can build this circuit with minimum / low cost. Active Tone Control or ACTOR is an active electronic audio circuit that serves to increase the… Read More »

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. The schematic is one channel (mono) tone control, build the similar circuit will make it become stereo channel. This Hi-Fi tone control circuit can be operated with wide range supply voltage, 12V – 24V… Read More »

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,… Read More »

Pre-Amp + Tone Control with TDA1524A

This is a low noise and distortion pre-amplifier and tone control circuit in one module. Using a special IC TDA1524A, this simple circuit is easy to build and will drive most of power amplifier. Schematic diagram:
