Electronics Help Care Amplifier circuit diagram

How to make a small amplifier circuit: This is a small amplifier circuit diagram. it’s 10 watts. this circuit run with 12 voltage to 15 voltage. this circuit used TDA2003. this is the mono-circuit diagram. if we need stereo then we have to use a dual circuit. One circuit for …

Microphone circuit diagram: This is the microphone circuit diagram. the maximum amplifier needs a microphone. without a microphone audio are nothing. for recording any audio we need a microphone. we hear sound this sound recorded using this type of circuit. this is so easy circuit. here used 3.7-volt battery.    …

5 voltage amplifier circuit: This is 5 voltage amplifier circuit diagram. it’s a 0.25 to 1 watt 4 ohms diagram. we can use 4 voltage to 12 voltage. this is a mono diagram. here we can use 2 watts speaker. if we want to make a stereo amplifier, we have …

Subwoofer amplifier circuit: This is the Subwoofer amplifier circuit diagram. this circuit is for the bass amplifier. when we want to make a sub amplifier then we need this circuit to make only bass. this circuit is used as a pre-amplifier. it’s made only of bass. low part only. here …

How to make a small amplifier: This is the circuit diagram for 20watts using tda2030. These chips run a 4Ω speaker at 18W or an 8Ω speaker at 14W. this circuit diagram runs with positive negative and ground voltage. we can use a maximum of 15-0-15 voltage. 12-0-12 voltage is …

Crossover circuit diagram: This is a Crossover circuit diagram. here have one output for the bass speaker. one for the mid-range speaker. and one for tweeter output. why do we need a crossover for the soundbox? if we don’t use crossover in the soundbox then we lost the tweeter and …

Headphone amplifier: This is a Headphone amplifier circuit diagram. sometimes we need an amplifier for our headphones because of the low sound volume. some tv has no headphone output line. there have only one audio pre-out for another amplifier. there we need this circuit diagram. this circuit runs with 5 …

Transistor amplifier circuit diagram: This is a transistor amplifier circuit diagram. it’s the basic circuit. transistor makes small to big. small sound to a big sound. transistor only makes small to big. there are two types of transistors. PNP transistors and NPN transistors. The PNP transistor is a negative transistor …

Bass tone circuit diagram: This is a Bass tone circuit diagram. this is a simple circuit. it’s a very simple circuit diagram. but the quality is very good. it’s making our amplifier quality full. we can control the sound using this circuit. here used 3 100k volumes. one for Bass …

Music light for the amplifier: This is the music light for the amplifier. this circuit is for the amplifier. this circuit we use in the amplifier. this light can make the amplifier look nice. here used a Kia6966s. this Ic has 5 led outputs. this circuit run 6 to 12 …
