Woofer Pre Amplifier 4558 OpAmp IC Low pass

In this video I will be showing you guys how to design the schematic diagram of the circuit.
Hi, Guys, This is Rudra Ghosh from https://rdgaudio.com and you are welcome to another video. This is the 2nd part of Two parts

video series.If you didn't watch the First Part Watch it here. https://www.youtube.com/watch?v=DiyY6K7UU6o.
In this part I will be showing you guys how to design an active low pass filter for Sub woofer.I am using Express PCB. It's a

Free but very powerful software for PCB and Schematic circuit design.

I am using KA4558 OpAmp but if you don't have 4558 you can use MC 1458/NE 5532/TL 062 or TL072 Opamp IC. I have used an external

amplifier and an eliminator for DC 12v power supply. Now a days this active low pass filter is used in almost every Sub Woofer

Multimedia Speaker system.It is also used in Graphic Equalizer circuits. Though the bread board circuit is looking quite

complicated but trust me guys this circuit is very easy to build.
