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 »

Tone Booster

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 – BC415p The circuit’s peaks frequencies is at 5000 Hz for a cleaner and more penetrating sound.… Read More »

ACTOR : Active Tone Control

The following diagram is the schematic diagram of Active Tone Control circuit, or we often call thic circuit as “ACTOR” Active Tone Control or ACTOR is a electronic audio circuit that serves to increase the Loudness (Bass and Treble audio signal) is active because it uses the Baxandall system. This circuit does not use a… Read More »

12V Stereo Tone Control

The following diagram is the circuit diagram of 12V stereo tone control which also available in kit, you may find the kit at electronic part store around your place. The circuit build based on ordinary tone control circuit, using 2 transistors FCS9014 in each channel, so there are will be 4 transistors in this 12v… Read More »

Basic Tone Control

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 –… Read More »

Hi-Fi Tone Control

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. Hi-Fi Tone Control was last… 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 »
