What are amplifiers?
An audio amplifier can provide amplification for one speaker or for many speakers to create surround sound. The maximum number of speakers depends on the number of channels the amplifier can handle. Amplifiers vary in quality of sound output and are one of the most critical parts of your Home Theatre installation. One of the most important components of your amplifier is the power supply. An insufficient or poor quality power supply can produce less dynamic, less detailed sound and reproduce interference noise through your speakers.
