Stereo Preamplifier with Bass-boost 2008-07-10 14:16:55 This preamplifier circuit was designed to cope with CD players, tuners, tape recorders etc., providing an ac voltage gain of 4, in order to drive less sensitive power amplifiers. As modern Hi-Fi home equipment is frequently fitted with small loudspeaker cabinets, the bass frequency range is rather sacrificed. This circuit features also a bass-boost, in order to overcome this problem. You can use a Read more:Stereo
Stereo PreAmplifier With Tone Control 2008-06-26 06:07:50 This is a preamplifier and tone control unit which will make a useful addition to any of our power amplifier circuits. It is extremely easy to construct due to the use of a special IC, The Philips TDA1524A.Because it uses voltage control, linear single gang pots can be used , which lowers the costs and reduces tracking errors. It also allows for control by switches or microprocessor if desired.Spe Read more:Control

USB Powered Audio Power Amplifier for PC 2008-06-26 05:54:19 This Power Amplifier
might be good solution to all of those who have PC with integrated sound card into motherboard. The main problem is that outputs of such sound cards are for active acoustic systems, this means that speakers must have power amplifier built in. If you decide to connect a headphones sometimes it might be not enough to provide required sound level.If you are an electronics amateur Read more:Audio
Low Voltage Audio Power Amplifier LM386 2008-06-23 23:01:10 The LM386 is a power amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200.Features:Battery operationMinimum external partsWide supply voltage range: 4V-12V or 5V-18VLow quiescent current drain: 4 Read more:Amplifier

Mosfet Audio Power Amplifier 18W 2008-10-24 22:12:30 This audio project is designing an audio amplifier capable of delivering a decent output power with a minimum parts count, without sacrificing quality.
This audio amplifier circuit employs only three transistors and a handful of resistors and capacitors in a shunt feedback configuration but can deliver more than 18W into 8 Ohm with <0.08% THD @ 1KHz at the onset of clipping (0.04% @ 1W - 1KHz Read more:Amplifier
