It means a player such as a stereo. Although there are different sound systems according to different requirements and tasks and different occasions, and the same type of sound systems are also quite different according to the number of functions and scale they implement, there are also differences in the composition and design of the sound system **Same rules.

The construction of a professional audio system generally takes the mixer as the center and grasps the ins and outs of the sound signal. The so-called ins and outs are the connection from the program source equipment to the mixer, and the so-called outgoing context is the connection from the program source equipment to the mixer. The main output of the mixer is sent to the downstream equipment, and depending on the system, it is sent to the recording equipment or the amplification equipment. In addition, the mixer is surrounded by audio processing equipment according to different needs.

For home audio systems, the preamplifier (preamplifier) ??is the center of the connection.

Extended information

There are different sound systems according to different requirements and tasks and different occasions. They can be divided from different angles. From a wide range, they can be divided into professional sound systems and Home audio system.

Professional audio systems can be divided into production systems and playback systems. Production systems include music recording production systems and film and television recording production systems. Regardless of which production system, sometimes it can be divided into pre-recording systems and post-production systems. , in addition to broadcast production (live or recorded) systems.

The playback systems include theaters, stadiums, conference venues, conference halls (rooms) sound amplification systems, dance halls, discotheques, karaoke sound systems, etc. Home audio systems can be divided into music playback systems and AV playback systems; AV playback systems include home theater surround systems and karaoke systems.

It should be noted that the above-mentioned production and playback systems are not absolutely separable. The production system also has playback functions, such as the monitoring part, and the playback system also has recording and production requirements and means. Such as live recording, the reason why it is divided just emphasizes the focus of the system.
