300-2500Hz Audio Bandpass Filter

This is an audio bandpass filter circuit which will filtering the audio frequency from 300Hz to 2500Hz.. The lower and higher audio frequency will be cut off. Download the explanation here

HiFi Audio Pre-amp

This is a HiFi pre-amplifier circuit diagram with low noise output. Very wide range frequency from about 10Hz until up to 100Khz will be gained by this preamplifier for maximum audio performance. This circuit uses BC550C / BC560C transistors as active component. Use regulated power supply 15VDC for maximum result.

4W Audio Amplifier using Transistor TIP41

This 4W Audio Amplifier circuit is powered by 2 pieces of transistor TIP41. 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 4W audio amplifier circuit is very simple and incorporates darlington output transistors that will provide… Read More »

5W Tube Amplifier with EL84

Here is the circuit diagram of the classic 5W Tube Amplifier with EL84 as the final amplification component. This is a single channel amplifier (mono) of course with single input and single output. You should build the two similar circuit to make it stereo.

20 Watt Stereo Audio Amplifier using TDA2005

This is the scheme diagram of 20 Watt stereo audio amplifier which use dual IC TDA2005, one IC for left channel and the another one for right channel. Each IC will give you 20 watt output, so the output will be 2×20 Watt. The supply voltage for this circuit is 8VDC to 18VDC, use regulated… Read More »

Loudspeaker System Crossover Network

Building a passive crossover for a speaker involves designing a network of passive electrical components (resistors, capacitors, and inductors) that split an audio signal into different frequency ranges and direct those ranges to the appropriate drivers (such as woofers, midrange speakers, and tweeters) in a multi-driver speaker system.. Here the simple passive schematic diagram of… Read More »

Schematic Diagram

In the electrical sector, a schematic diagram is usually used to describe the design or model of equipment. Schematic diagrams are usually utilized for the maintenance and repair of electronic and electromechanical devices / units. Original schematics were made by hand, using standardized templates or pre-printed adhesive symbols, but nowadays Electrical CAD computer software is often used.

In electronic design automation, until the 1980s schematics were virtually the only formal representation for circuits. More lately, using the progress of computer system technology, other representations were introduced and specialized computer languages were developed, because with the explosive development of the complexity of electronic circuits, classic schematics are getting less practical. As an example, hardware description languages are indispensable for contemporary digital circuit design.
