Electronics Help Care electronics circuit diagram Pre-amplifier circuit diagram:
This is a pre-amplifier circuit diagram. Every amplifier needs this type of circuit diagram. This circuit makes the sound good. It has one main volume, a low part, a mid-range, and a high. This diagram runs using a 12-volt only. it’s a mono board/ for stereo needs dual board.
Four variables are 100k.

How to make an amplifier circuit:
This is a mini audio amplifier circuit diagram. It can make 30 watts in bridge mode using 15 volts. This diagram needs a single voltage, positive and negative. It’s a mono diagram. To make a stereo need a dual board is needed. Here, use the TDA2003 IC. The dual IC needs to be in bridge mode. The IC needs a headsink. And the voltage must be good to make the best watts. We can use 8 volts to 18 volts. and up to 3 amperes.
We can get many amplifier circuit diagrams. This circuit can be used in a 2.1 sound box. We can make a subwoofer amplifier using this diagram. To make a subwoofer, we need a low-pass filter circuit. To get the lowpass filter circuit, please visit here LOWPASS FILTER. We need this low-pass filter to make a bass amplifier for 2.1 audio. This low-pass filter makes the sound only bass. It’s also a pre-amplifier. We can use this circuit in any amplifier to make a subwoofer amplifier.
