This is the circuit diagram of mic condenser amplifier. The low-cost and compact mic condenser audio amplifier described right here is deliver good-quality audio of 0.5 watts at 4.5 volts. It could possibly be applied as a part of low-power transmitters, packet radio receivers, intercoms and walkie-talkies.
This is the circuit diagram of Electro-Harmonix Soul Preacher pedal.
This is the very simple circuit diagram of 150W power amplifier. The circuit is easy enough to built without PCB. The power output range is about 100-150W depends to the power supply and the Darlington’s you use for the amplifier. Heatsink is a must since the final transistor is going to hot when the amplifier… Read More »
This is a very high 1500W power amplifier circuit diagram by Rod Elliott. The circuit is built using 10 pairs of power transistor MJ15024 and MJ15025 (or MJ21193/MJ21194), then it will use 20 pieces of power transistor for final amplification.
This is a high quality 65W power amplifier circuit based HEXFET IRF9540 and IRF540. The circuit is quite simple for amplifier with good sound quality. The component parts is easy to find at electronic store around your place. It uses split power supply. Q8, Q10, Q11, Q12, Q13 should be mounted on heatsink for thermic… Read More »
Parts List: R1-2-4-5=270Ω R3 = 2.7Ω VR1 = 10KΩ Log. Pot. TR1 = 470KΩ Trimmer IC1-2 = LM388 C1 = 100uF/25V C2 = 100nF C3 = 10uF/25V C4-5 = 22uF/25V C6 = 47nF
Here is the Hi-Fi compressor circuit with pre-emphasis. The above diagram is a circuit for a high fidelity compressor which uses an external op-amp and has a high gain and wide bandwidth. An input compensation network is required for stability.
Above circuit diagram is the schematic of 1W stereo headphone amplifier. The circuit is built based TDA2822, designed for use in portable players, radios and other common electronic devices which can use headphone for the audio output.
This is the schematic diagram of Western music generator circuit based on single IC HT82207. This circuit is able to take you towards the world of the Wild West. The western music already programmed in the chip. It utilizes the integrated 18-pin HT82207 (IC1) of Holtek, which literally takes care of almost everything.
