big e stereo parabolic microphone
This design circuit is for a stereo amplifier intended for a high-sensitivity stereo parabolic microphone, enabling the listening of distant sounds. Unlike typical parabolic microphones that are monophonic, this unit features a stereo audio path, resulting in more realistic audio...
Three-Level Audio Power Indicator circuit
This circuit is designed to indicate the power output level of any audio amplifier. It is simple, portable, and displays three power levels that can be set to any desired value.
The circuit operates by utilizing a combination of resistive voltage...
Audio Single Chip 25 Watt Mono Class-D Audio Power Amplifier Circuit
This class-D audio amplifier is suitable for TV and home stereo systems. The TDA7882 integrated circuit (IC) provides a class-D audio amplifier solution. Since this IC has a single channel output, two units are required for stereo applications. The power...
Compact High-Performance 12V 20W Stereo Amplifier
Amplifiers that operate on 12V DC typically do not deliver significant power and are often not classified as high-fidelity (hifi) devices. However, this compact stereo amplifier meets the power requirements effectively.
This compact stereo amplifier is designed to operate efficiently on...
2x20 Watt Stereo Power Amplifier
This project is based almost directly on the typical application circuit in the National Semiconductor specification sheet. You can also use the TDA2050 (from SGS-Thompson), which has almost identical performance and (remarkably) the same pinouts! As it turns out, the...
4 Watt audio Amplifier
The circuit is very simple and incorporates darlington output transistors that will provide more than enough output current than is needed to drive a 3-ohm speaker. The gain may be pre-set for a variety of input levels, making it suitable...
2W Amplifier
Designed for self-powered 8, 4 & 2 Ohm loudspeakers. This amplifier was designed to be self-contained in a small loudspeaker box. It can be fed by Walkman, Mini-Disc, iPod and CD players, computers and similar devices fitted with line or...
Turning Stereo Amplifer On and Off automatically
Is there an amplifier located in your living room, basement, or home theater that you would like to activate when music playback begins?
To achieve the desired functionality of automatically turning on an amplifier when music is played, a simple electronic...
8 Watts Audio Amplifier (TDA2003)
Nice small audio amplifier which use only few parts to give good quality sound. This amp can be used as a simple booster, the heart of a more complicated amplifier or used as a guitar amp. Although not perfect, this...
