What equipment does the hotel background music system need?

Hotels are places with a lot of people. The lobby, dining room, guest room, corridor and other places of the hotel must play different kinds of music, and should also have broadcasting and alarm functions. Therefore, the hotel's background music system needs sufficient equipment. Common hotel background music system equipment includes fire alarm equipment, control equipment, signal amplification and processing equipment, transmission line, speaker system and so on. Let's take a look at Bian Xiao. What equipment does the hotel background music system need?

1, fire alarm equipment

According to the low-voltage short circuit/open circuit signal from the fire sensor, it is triggered and transmitted to the fire alarm host, which controls the alarm signal generator, and then transmits the alarm voice to the speaker through the preamplifier and power amplifier to realize fire broadcasting.

2. Control equipment

The hotel background music system is equipped with a digital intelligent broadcasting host to realize automatic broadcasting, automatic control and automatic power management of the whole system.

3. Sound source equipment

Audio sources are usually provided by computer music, CD players and recording stands. The system is equipped with computer, radio head, microphone and DVD.

4, signal amplifier and processing equipment

For the broadcast system, as long as the total power of the broadcast speakers is less than or equal to the rated power of the power amplifier and the voltage parameters are the same, they can be connected at will, but considering the factors such as line loss and aging, power margin should be properly reserved. Therefore, the rated output power of the broadcast amplifier should be about 1.3 times of the total power of the broadcast speaker. In this system, three 1500W power amplifiers are configured according to the configuration requirements.

5. Transmission lines

Because the transmission distance will not be too far, high voltage and constant voltage transmission mode is adopted, which not only reduces the construction cost of the broadcast system, but also reduces the maintenance cost of the system in the later stage.

6. Speaker system

In principle, different kinds of broadcast speakers should be selected according to the environment. Sound posts and wall-mounted speakers are used in the basement, ceiling speakers are installed on the first to eighth floors above ground, and fire alarm forced volume controllers are installed on the first, second, third and fourth floors to cooperate with the consumer broadcasting system.

Functions of Hotel Background Music System

1. Zone broadcasting: it can be divided into multiple zones, and can be broadcast independently, and connected with the broadcasting room of the monitoring fire control room.

2. Automatic playback function: It can be played automatically every week or all year through the system according to the schedule set by the user. In case of emergency, it will automatically broadcast an alarm to the whole area or region.

3. Mass program source storage: the system host should have a large number of background music program sources built in.

4. Recordable and writable function: Users can edit and input the audio source into the system host through the computer and DVD/CD/MP3 to update the background music tracks and voice information in time.

5. Independent programming function: The playing schedule can be programmed by week or date, and the system will run automatically.

6. Manual function: there are both manual broadcasting and emergency paging alarm broadcasting.

7. Partition monitoring function: the system can monitor the content played in each area at any time.

8. Multiple programs can be played at the same time: IP network system is equipped with CD/DVD player, tuner and music program library, which can play programs and other music, and can play different contents in different regions at the same time.

9. Automatic sleep function: When the system is not broadcasting, the terminal server is turned off, and the speaker can't hear any noise (traditional broadcasting is always in standby state, and noise is inevitable). When a broadcast signal enters the terminal server, it will automatically release sleep and broadcast.

10, emergency broadcast: this system is connected with the fire control system, which can automatically stop the background music and start the emergency broadcast in case of emergency, and play the role of early warning, evacuation and alarm.
