The circuit of a 60 watt power amplifier is shown in the below figure. It’s design layout is simple and very conventional. It has a completely symmetrical pattern which has one pole frequency compensation, yet some uncommon methods have been employed in order to keep the number of parts less. To start with, the configuration […]
Newly Updated Circuit Projects:
Simple Tone Control Circuits
Tone control circuits are basically filter circuits which are used to filter audio frequency signals so that only the desired range of frequencies are allowed to pass to the amplifier and the loudspeakers. This enables the listener to customize the music output with either a high level of low frequency content through bass boost, or […]
Two Tone Door Bell Circuit
The electronic 2 tone door bell circuit is designed around the popular IC 555. The IC 555 is extensively applied in numerous varieties of timers and also as a basic oscillator circuit. In this particular project both the timer and the oscillator functions of the IC are utilized. As soon as the indicated push-button is […]
Bench Amplifier Circuit
A bench amplifier is a small test amplifier which includes basically all the features that are required for testing the performance of an input audio signal. It can be also customized as per the specifications of the input signal, so that you don’t have to build different sets of amplifiers for different test purposes. A […]
Public Address (PA) Amplifier Circuit
A public address system (PA system) is an electronic system that includes a set of audio electronic devices such as microphones, amplifiers, loudspeakers, and other similar audio equipment. It is designed to boost the volume of a human speech, or a musical source, or some other audible sound input to an amplified version through an […]
Listen to Wildlife and Insects with this Circuit
In this post I have explained a simple circuit idea which can be used for listening to the amplified sounds of insects and bugs in gardens, trees, or any deserted, quite backyards. Listening to the noises of outdoor wildlife may be a genuine auditory delight as well as a signal of impending danger. When it […]
