Abstract: The hotel is a place with a very large flow of people. Different music must be played in the hotel lobby, restaurant, guest rooms, corridors and other places, and it also has broadcast and alarm functions. Therefore, the hotel background music system needs to have Sufficient equipment. Common hotel background music system equipment includes fire alarm equipment, control equipment, signal amplifiers and processing equipment, transmission lines, speaker systems, etc. Let’s take a look with the editor. What equipment is needed for the hotel background music system
1. Fire alarm equipment
The low-voltage short circuit/open circuit signal transmitted from the fire sensor is triggered and transmitted to the fire alarm host, and the fire alarm host controls the alarm. The signal generator then transmits the alarm voice to the speaker through the preamplifier and power amplifier to realize fire broadcast.
2. Control equipment
The hotel background music system is equipped with a digital intelligent broadcast host to realize automatic broadcast, automatic control, and automatic power management of the entire system.
3. Audio source equipment
Audio sources are usually provided by computer music, laser record players, recording decks and other equipment. This system is equipped with a computer, radio head, microphone and DVD.
4. Signal amplifier and processing equipment
For broadcast systems, 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 configured at will. However, considering factors such as line loss and aging, appropriate power margin should be left. Therefore, the rated output power of the broadcast amplifier should be about 1.3 times the total power of the broadcast speaker. In this system, three 1500W power amplifiers are configured according to the configuration requirements.
5. Transmission line
Since the transmission distance is not too far, the use of high-voltage constant-voltage transmission method not only reduces the construction cost of the broadcast system, but also reduces the later maintenance cost of the system.
6. Speaker system
In principle, broadcast speakers of different types and specifications should be selected depending on the environment. Sound columns and wall-mounted speakers are used on the underground floor. Ceiling speakers are installed on the first to eighth floors above ground. Fire alarm plug-in volume controllers are installed on the first, second, third, and fourth floors to be used in conjunction with the consumer broadcasting system. .
Functions of the hotel background music system
1. Zone broadcasting: It can be divided into multiple zones and can be broadcast independently and connected to the fire control monitoring room broadcasting room.
2. Automatic play function: The system can automatically play weekly or throughout the year according to the schedule set by the user. In the event of an emergency, an alarm will be broadcast automatically to the entire district or partition.
3. Massive program source storage: The system host should have a large number of background music program sources built-in.
4. Recording and writing function: Users can edit and input audio sources such as computers and DVD/CD/MP3 to the system host to update background music tracks and voice information in a timely manner.
5. Independent programming function: the playback schedule can be programmed and entered according to the day of the week or date, and the system will run automatically.
6. Manual function: It also has manual broadcast and emergency paging alarm broadcast.
7. Partition monitoring function: The system can monitor the content played in each area at any time.
8. Play multiple sets of programs simultaneously: The IP network system is equipped with CD/DVD players, tuners, and music program libraries, which can meet the needs of music playback such as programs, and can simultaneously play different programs in different areas. content.
9. Automatic sleep function: When the system is not performing any broadcasts, the terminal server is shut down and no noise can be heard from the speakers (traditional broadcasts are always on standby, and noise is unavoidable). When a broadcast signal enters the terminal server, it automatically releases the dormancy and broadcasts.
10. Emergency broadcast: The system is connected to the fire protection system. In an emergency, it can automatically stop background music playback, start emergency broadcast, and perform functions such as early warning, evacuation, and alarm.
