When using one of our amplifiers big or small you always need a volume control and preferably also a tone control.
Tone control 4558 preamplifier circuit diagram.
This is a single channel audio amplifier circuit.
New material on the musical instrument amplifier tone stack has been added at the end of this page.
Two npn transistors bc107 are used in this circuit this circuit is biased by 30 volt dc power supply audio input taken through the 2 2μfd capacitor and separated into two lines to control bass and treble effects output from the tone control elements are fed into transistor pre amplifier output is synchronized and then fed into the output.
4558 ic audio power amplifier circuit diagram.
Stereo volume control stereo baxandall.
It can control the sound bass treble volume well.
Mic pre amp circuit using ic 4558 is a series of mic amplifier based on ic 4558 and also could use other op amp ic ie tl072 tl082 ne5532.
This is circuit diagram of powerful audio amplifier.
This circuit operated with 12v symmetrical dual polarity power supply.
The ic requires very few external components has very low noise and has a wide power supply voltage range.
I have lately found that there is a lot of interest in tone control circuits.
This circuit available in kit.
Subwoofer module amplifier circuit is indeed very popular with the audio hobbyist.
The circuit that i publish is a circuit of modules that use the subwoofer amplifier ic op amp 4558 which acts as a reinforcement of bass tones subwoofer assisted of it s by the workings of some supporting components such as resistors capacitors.
This is the circuit diagram of stereo pre amp with volume and tone control.
We use the a ne5532 is the heart of the circuit.
We recommend the low noise pre tone control circuit using 4558 instead.
