A stereo receiver is an electronic device that amplifies audio signals and allows users to control sound from various sources, such as CD players, turntables, and streaming services. It typically includes a radio tuner, enabling users to listen to AM and FM stations, and often features multiple inputs for connecting different audio devices. In addition to amplification, a stereo receiver can manage sound settings, such as bass and treble adjustments, to enhance the listening experience. Many modern receivers also support Bluetooth and Wi-Fi connectivity, allowing users to stream music wirelessly from their smartphones or tablets.
