What is STV8224B?
This is MULTISTANDARD VIDEO AND SOUND IF SYSTEM WITH AUDIO AND VIDEO SWITCHES. An audio power amplifier is an electronic device that amplifies low-power audio signals to a higher power level, suitable for driving speakers or other types of loads. The amplifier takes an input signal, typically from a preamplifier or a mixer, and increases its power to drive the loudspeakers, without distorting the sound. The choice of amplifier class depends on the application and the requirements of the system. |
