In addition, 2-channel amplifiers are different and more advanced, more expensive due to integrated technologies such as: Class H, Class D, Class TD.
2 channel amplifier structure
Do you know what the internal structure of a 2-channel amplifier consists of? A 2-channel amplifier is an audio device used to enhance the audio signal and deliver it to the speakers. It consists of 2 independent channels, each of which can be adjusted separately. The structure of a 2-channel amplifier includes the following components:- Input: This is where the audio signal is fed into the amplifier, usually from a mixer or preamplifier.
- Control Knobs: The control knobs are used to adjust the loudness of the audio signal on each individual channel. These knobs include: Gain, Volume, Treble, Bass, and Balance.
- Filters: Filters are used to adjust and balance the audio signal, including bass, mid and treble filters.
- Output: This is where the audio signal is taken from the amplifier and goes to the speakers.
