Bull horn
The input audio signal is connected to pin 3 of U1, an LM386 low-voltage amplifier, through capacitor C3 and resistor R1. The potentiometer R1 adjusts the drive or volume level. U1 functions as a driver stage, with a gain that...
50mW amplifier schematic
Here is a little audio amplifier similar to what you might find in a small transistor radio. The input stage is biased so that the supply voltage is divided equally across the two complimentary output transistors which are slightly biased...
Simple Audio Mixer Circuit
The simple audio mixer circuit is built on the common base principle, where input voltages are transformed into alternating currents which are summed to form the output.
The simple audio mixer circuit utilizes a common base configuration to achieve effective mixing...
Audio Amplifier Diagram
The circuit is based on four integrated circuits: TL072, TL074, MN3101, and MN3004, which produce four output channels for surround audio, specifically targeting center, rear, front right, and front left audio. It is a compact amplifier capable of delivering 7W...
Small amps Gibson GA5
The new TNT amplifier features both pre-amplifier and output gain selection switches, with selectable output power of 8 watts and 2 watts. It includes an "interlink" master volume control, bass and treble controls, and an "auto-aligning" output stage that automatically...
LM381 4 channel audio mixer circuit design
LM381 4-channel audio mixer circuit design project using a few common electronic parts.
The LM381 audio mixer circuit is designed to combine audio signals from four separate channels into a single output. This circuit employs the LM381 integrated circuit, which is...
100w audio amplifier
This amplifier features high fidelity (Hi-Fi), high sensitivity, low power consumption, and low distortion, making it an excellent choice for high fidelity sound systems. The process of creating a printed circuit board (PCB) can be accomplished in a few straightforward...
Audio Signal Testing amplifier
This mini audio amplifier will test the audio stages in amplifiers such as the front end of FM bugs. You can also use it on lots of our other projects as well as the output stages of radios. It is...
1W stereo Headphone Amp (TDA2822)
A stereo power amp designed for use in portable players and radios. A 3V supply can be used to drive headphones providing 20mW in 32 Ohms per channel. A 9V supply will provide 1W in 8 Ohm per channel for...
