This 200 Watt high quality power audio amplifier will give you top class quality for loudspeaker 4 – 8 ohm. Frequency range 20-20000Hz, Voltage 24-36V with current max 5A. You need heatsink to keep the transistor from overheating. Itu use dual polarity power supply to work, then you may use this power supply to supply… Read More »
Here the schematic diagram of 800 watt audio power amplifier with MOSFET for final amplification. This amplifier can be used for practically any application that requires high power, low noise, distortion and excellent sound. Examples would be Sub-woofer amp, FOH stage amplifier, One channel of a very high-powered surround sound amplifier etc.
This is the circuit diagram of low impedance microphone amplifier. The circuit designed for use with low impedance (~200 ohm) microphones. It will work with regulated voltages between 6-30VDC. If you don’t build the impedance adapter part with T1, you get a microphone amplifier circuit for higher impedance microphones. In this case, you should directly… Read More »
This is high fidelity, high quality 25W HiFi audio amplifier circuit delivers great audio performance. You don’t need pre amplifier circuit for this design since it can be directly connected to the input devices such as computers, phones, radios, TVs, etc. Component list: R1,R4 = 47K 1/4W Resistors R2 = 4K7 1/4W Resistors R3 =… Read More »
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 »
This is 20 watt audio amplifier circuit design which use IC LM1875 as main component. This circuit is simple and very easy to built. For stereo channel, you need to build the two same circuits which will amplify the both of audio channels (right and left channel). Dual polarity / symmetrical power supply required for… Read More »
