What devices are commonly used in background music systems?

The background music system connects the sound source signal to every room and the place where the background music system is needed through professional wiring. A background music controller is installed in any room, so that every room can hear wonderful music. The common equipment in background music system includes audio playback equipment, audio output equipment, output control equipment and output control equipment. Be sure to pay attention to the method when buying. Let's take a look at Bian Xiao. What devices are commonly used in background music systems?

1, audio playback device

Comprises a signal source and signal processing equipment. The signal source can be DVD, CD, MP3, or simply a computer. Signal processing equipment can be regarded as a power amplifier in general, but it is necessary to realize the simultaneous output of multiple audio channels through the power amplifier, that is, the enjoyment of audio output.

2. Audio output equipment

To put it bluntly, the output device is the speaker. The speakers used for background music are different from ordinary home theaters. Its speakers are required to be beautiful, hidden and integrated with the environment. Therefore, ceiling speakers are generally used for users who use ceilings in home decoration, and flat wall-mounted art speakers can be used for users without ceilings. The so-called flat wall-mounted art speaker is just a picture in appearance. This kind of sound box actually produces sound by exciting bending waves in the sound board. The flat wall-mounted art sound box fully meets the demand of beautiful and hidden audio output equipment for family background music.

3. Output control equipment

In addition to the playback device and audio output device, there is also an output control device for background music. The advantage of this is that each room can control its own playback volume. For example, if someone is sleeping in the bedroom and people in the living room want to enjoy music, they just need to turn on the background music speaker in the living room.

4, signal amplification and processing equipment

For the audio output by the sound source equipment of the background music system, after amplification and signal equalization, the audio signal can be converted into high-voltage and constant-voltage signals through a constant-voltage amplifier and transmitted to the speaker. If there are multi-source devices, such as DVD, microphone, card stand, MP3 host, etc. , you need to configure the preamplifier or mixer separately.

Matters needing attention in purchasing background music system equipment

1. Because the installation of the music host needs to cut the wall and slot, when choosing, remember to buy the model of GB 86 bottom box size. The oversized mainframe is not only complicated in slotting, but also incongruous with the adjacent switch panels, which not only affects the beauty of the home, but also brings unnecessary trouble to the reuse of slots in the future.

2. In terms of security, the background music system belongs to the category of home improvement, which is different from the traditional digital fast-selling products. It is like a music switch at home and must stand the test of time. This means that the life design should ensure its stability and long-term operation.

3. The CPU of the background music system is very important, and the heat dissipation problem is usually the source of the instability of the whole machine. In order to save trouble, some music hosts in the market directly embed the power amplifier into the host with a small space, which leads to the difficulty of heat dissipation in the closed wall of the host, which ultimately affects the stability of the system, and may seriously burn accessories or even cause a fire. Therefore, when purchasing a host, you must carefully ask the owner whether the brand has strong and weak electricity separation, power amplifier separation from the host, and whether its products have national 3C safety certification and other safety-related knowledge. After all, life is precious.
