Circuit Diagram of 50W Hi Fi amplifier with TDA7294


The TDA7294 is a Hi-Fi amplifier and can give 100W RMS but with 10% distortion. Supplying 30 Volts you can have 50 Watts RMS with 1% distortion. Frequency range start at 16Hz and can reach 100KHz. Make sure you are using good heatsink. The chip supports mute function as well.

Echo effect with IC PT2399 schematic

Image
Effect Echo is an electronic circuit that is used to delay sound or make an echo in an audio circuit . Using a circuit of echo is easy enough , we just set on the volume, and gain and trimpot near is rate of 20 K ohm to adjust how the desired echoes. This echo circuit using ic 4558D for additional amplifier and ic PT2399 as a major component that serves to echo , or repeat the sound output on the audio system. Click image to view larger  How to use it as follows : That is initially given the output of the mic input or other equipment. Then turn down the volume, and slowly raised, setting echo effect on the trimpot 20K. If not check back for the damaged to the circuit.

Build your own programmable power supply with TL431

Image
TL431 and LM431 are relatively low-noise, stable and low-cost shunt regulators. These can be used to build all sorts of power supplies including programmable power supplies, advantages of which are enormous. You can program the output voltage with simple switches. You can also program the output voltage with digital codes coming from a microcontroller (MCU) or from the printer port of a PC. You can adjust any output voltage individually with resistors or trimmer potentiometers to the required values. This article presents a programmable power supply built around TL431 (IC1) and two bipolar transistors BD139 and TIP31 (T1 and T2). The circuit also includes an inverter 7406 (IC2), nine diodes 1N4007 (D1 through D9), a 12V regulator 7812 (IC3), a 5V regulator 7805 (IC4) and a few other components. Using this circuit you can obtain around 18V, 2A unregulated output and 3V to 15V, 1A variable regulated power supply based on digitally programmable input as shown in Table I. You can also obta...
