Haikou, Hainan meeting campus radio background music broadcasting system installation of high-grade durable

Haikou campus radio, Hainan conference background music broadcasting system installation company to undertake high-grade durable indoor and outdoor public address system projects, including schools, squares, playgrounds and other outdoor public broadcasting background music systems and indoor shopping malls, hotels, restaurants, school buildings, office building and other public broadcasting system, including construction wiring, threading, sound installation, commissioning stereo. Features background music broadcasting system called BGM, is an abbreviation Back ground music, its main role is to cover up the noise and create a relaxed and harmonious atmosphere, listening to people if not concentrate on listening, we can not identify the location of the sound source, volume compared small, it is a creation of a relaxed atmosphere of the music. Therefore, the effect of background music are the two psychological cover environmental noise, and the second is to create the atmosphere of the indoor environment to adapt, it is widely used in hotels, restaurants, shopping malls, hospitals, office buildings and so on. Regardless of the composition of radio and audio systems which broadcast sound system, basically divided into four parts: a program device, amplifying the signal processing equipment, transmission lines and speaker system. Source Device Source Device: program source usually radio, CD player and tape deck, and other devices, in addition to microphones, electronic musical instruments. Signal amplifier and processing equipment signal amplifier and processing equipment: including equalizer, pre-amplifier, power amplifier and a variety of controllers and audio processing equipment. The primary task of this part of the device is the signal amplification, followed by the selection signal. Mixer and preamp similar role and status (of course, the mixer functionality and higher performance), their basic function is to complete the selection and pre-amplified signal, also responsible for the volume and sound effects to make various adjustments and control. Sometimes, in order to better carry out the frequency balance and timbre landscaping, also separately invested graphic equalizer. This part is the "control center" the entire broadcast audio systems. Then the amplifier or mixer amplifier signals sent by pre-power amplifier, and then to push through a transmission line speaker burst. Transmission line transmission lines: the transmission line is simple, but with different systems and transmission methods and have different requirements. For the hall, theater, etc., as far from the power amplifier and the speakers, the general low-resistance high-current direct feed mode, the transmission line requires dedicated speaker wire, while the public broadcasting system, because wide service area, long distance, in order to reduce loss caused by the transmission line, often using high-voltage transmission mode, since the transmission current is small, it is less demanding on the transmission lines. Speaker System: Speaker System requirements match the entire system, and select its location also realistic. Auditorium, theater, dance hall sound, speakers generally use high-power speakers; and the public broadcasting system, because it sounds less demanding, generally with 3W-6W ceiling speakers can be.
