In this project, we are going to show you making a Hi-Fi

Stereo Amplifier Circuit Using TDA2616 Sound IC. It is a very powerful amplifier circuit and you can make this amplifier circuit at home easily. TDA2616 IC made can produce up to 2*12 watts. You can use this amplifier circuit at your home, office, byke, car, truck, and anywhere. This circuit doesn’t have any humming sound.

To Make this amplifier circuit, you might need some electronics components. Those component lists have to been given below.

Component List :

1. Sound IC – TDA 2616

2. PF – 2A104j (4 Pieces)

3. Resistor – 2.2 Ohm (2 Pieces)

4. Speaker – 2 Pieces

5. Power Supply

6. Heat Sink

7. Audio Input Cable

In this project, we are going to show you making a high-power amplifier circuit. Using this circuit you will get the best quality sound. You can make this circuit at home easily. You can use this amplifier circuit at home, inside your car, bike, truck, etc.

To make this circuit, you might need some electronics component, those component lists have to been given below.

Component List :

1. Sound IC - TDA 2030

2. Resistor - 1 K 10 K (2 Pieces) 150 ohm

3. Capacitor - 2.2uf/ 50v (2 Pieces)

4. PF - 2A104J

In This Project, We Will Tech You, How To Make A Simple Bass Booster Circuit At Home Easily. You Can Make This Circuit At Very Low Cost.

To Make This Amplifier Circuit We Will Need Some Electronics Component.

Component List :

1. Mylar Polyester Film Capacitor – 2A104J (2 Pieces)

2. Resistor – 1 K Ohm & 1.5 K Ohm

3. Potentiometer – B 100 K

First We Connect Mylar Polyester Film Capacitor With Left
Leg Of Potentiometer. Then Connect Another Mylar Polyester Film Capacitor With Right Leg Of Potentiometer & Connect The Empty Leg Of Mylar Polyester Film Capacitor. Connect Potentiometer Middle Leg With Joint Leg Of Mylar Polyester Film Capacitor & Connect 1 K Resistor With Joint Leg Of Mylar Polyester Film Capacitor. Now Connect 1.5 K Ohm Resistor With Left Leg Of Potentiometer.

It Is The Time To Connect Audio Input Cable. In This Cable There Are Two Terminal. 1st Terminal Have 3.5mm Audio Input Jack And 2nd Terminal Have Two Cable. Between These Two Cable One Is Ground (-) Cable And Another Is L/R Cable.

Though It Is Mono Amplifier, It’s Have Two cables. If It Is Stereo Amplifier There Are Three Cable. 1st Is Ground (-), 2nd Is “L” & 3rd Is an “R” Cable.

Now Connect Audio Input Ground (-) Cable With Empty Leg Of 1.5 K Ohm Resistor And Connect Audio Input L/R Cable With Right Leg Of Potentiometer.

Now, We Use A Cable To Connect Bass Booster Circuit With Amplifier Circuit. Connect Audio Output L/R Cable With Empty Leg Of 1 K Ohm Resistor Of Bass Booster Circuit & Ground (-) Cable With Audio Input Ground Cable Of Bass Booster Circuit.

Now Connect Bass Booster Audio Output Cable With Audio Input Leg Of Amplifier Circuit. Our Circuit Is Now Ready For Use. Just Connect 3.5mm Audio Input Jack With Mobile & Play Music. Now You Can Adjust Volume Using Potentiometer.

In this project, we are going to show you making an amplifier power supply for the tda2030 and tda2050 IC-made amplifier circuits. Using In this circuit you will get the best quality sound from tda2030 and tda2050 IC made amplifier.

To make this circuit we might need some electronics components. Those component lists have to been given below.

Component List :

1. Capacitor - 4700uf/ 25v (2 Pieces)

2. Rectifier Diode - 1N5408

3. Transformer - 12:0:12

4. Soldering Iron
