“So on my Youtube channel, many people ask how to combine two amplifiers into one. The first amplifier is used for satellite speakers and the second amplifier is used for subwoofer speakers. This amplifier installation configuration can be called Amplifer 2.1.
To answer that question, in this article I will create a tone control for the 2.1 amplifier. So this tone control can divide one audio source into 3 outputs. the first and second outputs are for the satellite speaker amplifier and the third output is for the subwoofer speaker amplifier.
This tone control can be supplied using a single power supply or a symmetrical power supply. Need special configuration for the use of each type of power supply. I will explain how to configure it in the article.”
