What Is a Multi-Room Amplifier?

The so-called background music system is an integral part of the smart home. That is, in any house including: living room, bedroom, kitchen and bathroom, etc., music lines can be laid, and through one or more sound sources, people can hear beautiful background music in each room.

Background music system

The so-called background music system is

There are many ways to enjoy music in a family. For example, in the living room, we usually have audio, in the study, bedroom, we also have micro

The digital home is the dream of many people, but what does a real digital home look like. What components are included and how should we form a digital home? I believe many readers are still confused about this. At the time when the flat-panel TV boom and HD home theater are in the ascendant, a considerable number of friends believe that they have purchased several LCD TVs,

Home background music speakers are divided into two types: hanging and ceiling.

If the ceiling in the home is high (at least 2.7 meters or more), you can use the ceiling type, embedded in the ceiling, which is very beautiful. The fixing method is the same as that of the ceiling lamp. Basically, the depth of ceiling speakers is between 10mm and 80mm.

According to the number of rooms and different needs, the following four options can be adopted.

1. The broadcast control room can program, monitor and centrally control the entire system, while monitoring the working status of the system, displaying the working status of each broadcast partition, each input / output terminal, power amplifier equipment, channel occupation status and fault information, etc. .

2. In addition to the programs that can be played by the front-end audio source equipment , the system should also be able to play the real-time voice of the remote microphone. System programs can be split and transmitted to all public areas in the building at the same time.

3.The system can be controlled by

The development trend of background music is toward the health sound system

In 1906, American DeForest invented the vacuum triode, which pioneered the human electroacoustic technology. In 1927, Bell Labs invented the negative feedback technology, which brought the development of audio technology into a brand-new era. More representative ones, such as Williamson amplifiers, successfully used negative feedback technology, which greatly reduced the distortion of the amplifier. In the 1950s, the development of tube amplifiers reached a climax period, and various tube amplifiers emerged endlessly. Due to the sweet and round sound of the tube amplifier, it is still preferred by enthusiasts.

The advent of the transistor in the 1960s enabled the majority of audio lovers to enter a wider audio world. The transistor amplifier has the characteristics of delicate and beautiful sound, low distortion, wide frequency response and dynamic range.

In the early 1960s, the United States first introduced a new member in audio technology-integrated circuits. By the early 1970s, integrated circuits were gradually recognized by the audio industry for their high quality, low price, small size, and multiple functions. Since its development, thick-film acoustic integrated circuits and operational amplifier integrated circuits have been widely used in acoustic circuits.

In the mid-1970s, Japan produced the first field-effect power tube. Because the field effect power tube also has the characteristics of pure tube thickness, sweet sound and dynamic range of 90dB, THD <0.01% (at 100kHz), it will soon become popular in the audio industry. Many amplifiers today use FETs as the final output. Subsequently, home-use audio combinations have been launched, and the concept of home audio has risen.

In 2002, the concept of "central network audio system" was put forward, and the embodiment of family background music began to be established.

In 2008, in-depth research on the traditional concept of "central network audio system", combined with art audio, put forward "health sound system", and with the mission of "let music improve human life", once again adjusted the sound Reorientation in people's lives: music health, improve human life!

In 2013, after years of development by relevant agencies, the background music system is an embedded computer control panel and DSP music signal processing. The background music signal is processed by software, and humane and intelligent technology is applied; all the equipment uses lead-free environmental protection components The core components are produced in China, and the product quality is stable and reliable.
