2.1 HOME THEATER

                                                             2.1 HOME THEATER

2.1 channel speakers means that you have 2 regular speakers (usually in Stereo) and then a Sub woofer for extra bass.

We seen about the 2.1 home theater system making the IC 2030 it amplify  the audio signal 20 W

operating voltages are the +9 volt to +24 volt.

circuit shown below screenshot.

it consist of few circuit combinations

• Rectifier
• Voltage regulator
• Pre amplifiers 
• Amplifiers 

below screenshot are presented the PCB diagram it is the double layer diagram.

in this diagram 2.1 home theater  prototype 3D model  .which helps the over all view of the 2.1 home theater mother board.

TECH - DETAILS:

woofer power rating  : 2 x 18 = 36 WATTS.

Sub woofer power rating : 1 x 18 = 18 WATTS.


Total Power capacity : 36 + 18 = 54 WATTS.



INPUT  POWER SUPPLY = 12-0-12 V / 3 A.

BRIDGE RECTIFIER :


   

We are using the four number  of  1000 u / 35 v capacitor like filtering purpose.
So we  get the very low ripple fine DC output.
