Are you planning to build your own Audio amplifier at home? So you must need to add a potentiometer to adjust the volume of the audio. connecting Potentiometer without knowledge makes noise, and lack of user user experience. So check this article to know about how you can perfectly do connections on your potentiometer to control volume.
Importance of High Quality Volume Control in Amplifier
The volume control or the connecting potentiometer is an important part in audio amplifiers. Improper connection and usage of the potentiometer may lead to break your audio experience and also the user satisfaction.
The high quality volume control will provide Precise adjustment in volume control. Not only the adjustment of the connection of internal volume control should be proper. So the high quality volume controller and its circuit should be the best to get the best audio output.
Connection of Potentiometer for Better Audio Quality
The input of this circuit is connected to the output of the audio source such as USB board or TV. The Dual gang potentiometer is using to control the audio signals.
the output is connected to the audio amplifier board. The performance chart of this circuit is also attached with this circuit.
Audio Response Chart while Connecting Potentiometer in this way
From the chart THe Db os representing on the left side and Potentiometer rotation is representing on the horizontal line.
From the chart it is clear that from 25 dB range to above a linear line is getting this means the while rotating potentiometer a linear or smooth volume controlling you can feel on your audio.
