Find below is the list of audio amplifier circuits.
Tone control or Active equalizer circuit especially bass, treble, and MID control based Equalizer is an important circuit in audio amplifier design. Generally, three-stage active Equalizer filters require three control bass, treble, and MID. The bass control allows the low frequency to pass but blocks high frequency and the treble control allows the high frequency to pass…
Nowadays, most of us like to listen to music, with our smartphones. But a few years back, this was not the case, at that point in time, FM radios were the first choice for listening to music, podcasts, news, and others. Nowadays nobody listens to the radio for music, news, and others, grandma and grandpa being an exception.
So, to revive the old…
A potentiometer is a mechanical device using which one can set the resistance according to the desired value, thus changing the current passing through it. There exist many applications for a potentiometer, but mostly, a potentiometer is used as a volume controller for audio amplifiers. The digital volume control circuit is an electronic circuit that accurately adjusts…
Often times, we need to control bass, treble, and volume of our audio signal before passing it through amplification stages to prevent sound distortion. The circuit that amplifies the audio signal before it enters the main speaker amplifier is called an Audio Preamplifier. The use of an audio pre-amplifier ensures good audio quality and provides options to modify our sound…
Who does not like the rumbling tone of a distorted electric guitar? It is a key part of many important genres of music, especially in blues and rock music genres and is also frequently used in hard rock, metal or the punk music genre. In this project, we will build a basic distortion pedal for guitars using a simple circuit. You can also check out the Arduino Guitar Tuner Circuit if you are…
The LA4440 is a very popular dual-channel audio amplifier commonly used to build high power audio amplifiers. The IC is known for its high power, easy availability and cheap price which makes it popular among Home Theatre and Car Amplifier Systems which operate on 12V. Hence in this article, we will learn how to build a High-Power Stereo Audio Amplifier using the LS4440…
If you are thinking about building a simple, cheap, and moderately high power amplifier circuit that can deliver up to 50-watt peak RMS power into a loudspeaker, then you are in the right place. In this article, we are going to use the most popular TDA2050 IC to design, demonstrate, build, and test the IC to achieve the above requirements. So without further ado, let's get…
Have you ever set an important reminder on your phone only to miss it because the device was in silent mode, left in another room, or buried under tons of notifications? While smartphones have made reminders convenient, they are not always used in every situation, especially for elderly people, students, or professionals with busy schedules.To solve this problem, we…
Today almost everyone uses their mobile phones to listen to music, news, podcasts, etc. But not long ago we were all depending on local FM Radios to get the latest news and songs, slowly these Radios are losing popularity but in emergencies when the internet is down, radios place an important role to transmit information to the users. Radio signals are always present in the…
Loudspeakers are heavy loads, and they normally require high current to be driven which is provided by an external circuit. This is because sometimes the produced sound output, let's say from a microphone or the pickup coils of the guitar, do not produce high current high amplitude output, therefore, it is not suitable to drive a loudspeaker. This is why we have something…
Text-to-speech or TTS system converts normal text into Speech. This tech enables the system to speak out the text in a human voice. There are many examples of Text to Speech conversions like the announcements at public transport, the customer care calls, voice assistants in your smartphones, or the navigation menu of any machine. You can even find the TTS in Microsoft Word…
Audio Mixer is an essential device in Audio Electronics. The mixer mixes two or more audio signals into a one (Mono) or two output (Stereo). The audio mixer uses audio mixing process where multiple sounds are combined to form a single or multi-sound. It is a widely used process in Live concerts, televisions, films, music industries etc.
In this…
