The frequency is used to separate the sound signals from the different bands, to be zoomed in and then replayed in the speaker in the corresponding band. When high-quality sound is replayed, electronic frequency processing is required。
The frequency is the "brain" in the soundbox, which is critical to the sound quality. The output music signal shall be processed through the filtering wave element in the frequency, allowing the unit-specific frequency signal to pass. Scientificly, rationally and carefully designed soundbox frequencies are necessary to effectively modify the different characteristics of the speakers ' units, optimize their combinations, keep them short, make their respective potentials fully operational, and smooth and symmetrically accurate the sound of the bands, so that the music produced by high, medium and low sound is clearly structured, integrated, clear, comfortable, broad and natural. Mixing time: refers to the time, in seconds, that will be required for the sound pressure level to drop 60 db in the hall following the sudden interruption of a stable sound signal.

Digital cd player (dvd player), commonly known as dvd player, is the device for playing digital cds. Most uses need to be connected to television. In addition to this, there are products with liquid crystal displays。
The basic functions of dvd players are as follows:
1. Read dvd-video (udf version 2 format)。
*** content processed by css or macrovism。
3. Wave shape of the macrovision anti-turban signal
Decode mpeg-2 video stream to compare the peak rate of 10 mbit/s and the continuous rate of 8 mbit/s。
Decoding sound formats code mp2, pcm or ac-3, output by stereo connector fibre or electronic digital connector。
6. Output video signals, in which analogue signals (pal, secam or ntsc format) use colour*** signal connectors and digital signals use digital video interface connectors。
Most dvd players can also play audio cds (cdda, mp3, etc.) and vcds, which include a home cinema decoder such as dolby digital, dts; new products also support the popular video compression format divx on the internet。
A linear array of intelligent stage sound market prospects is a set of lined, closely spaced radiation units with the same amplitude and phase。
Acoustic speaker means a type of soundbox inside the soundbox with its own hand-held. They are dedicated to the promotion of speakers in soundboxes and, as a result of specialized matching designs, they can be better used for the promotion of speakers in soundboxes so that users do not have to consider how powerful they are and whether resistance is compatible. In addition, because of the presence of an electronic frequency split frequency in front of the amplifier and the fact that each installation ** is responsible for magnifying a frequency audio signal, the amplifier tends to be more efficient and less deceptive。
In addition, there are a number of audio *** audio-recording devices with built-in powered circuits and electronic audio-message boxes with built-in electronic split-frequency circuits and amplifiers that can also be included in the active sound-box category。
Over the past few decades, large-scale linear array applications have been very*** and are well known. However, a new compact array system has begun to emerge and is applied to small activities, with the advantages of large arrays。
In the application of large soundbox arrays, almost everyone is aware of the limitations of large soundboxes: weight, size, price, vertical radical effects are difficult to make when arranged in arcs, because of their size, and these factors have made the linear placement of soundboxes unpopular in small activities, where traditional module speakers are more suitable. A compact stereo linear array is a better solution for small-scale activities and economic budgets, so that a larger audience can enjoy the wonderful effects of a live sound. Conference room sound system engineering: the way the soundbox is placed, the selection of the conference microphone, the selection of the host of the digital wireless meeting control system。
Specialized stage sounding devices include: *** modulation stations; dyslexes; portable stereos; power amplifiers; action loops; condensers; radios; microphones; soundboxes; *** soundboxes; ** soundboxes; equalizers; mixers; effectsers; time extensions; compressors; amplifiers; diaphragms; noise doors; laser singers; audiocards; video discs; projectors; transformers; nodes; headsets; etc。
The tuner is the professional responsible for all the sound devices on the stage. First, all sound sources need to be assembled at the sound bar, divided into side roads, grouping, and calibration, and then the main-way output sound balance is sent to the speaker and the speaker to match the sound characteristics of the site. The tuner needs to know the musical characteristics of each link, ** the frequency of easy feedback and the resonance points of the site to control the volume of each song and to balance them. In addition, the non-used voice, musical sound and familiarity with the functions and limitations of each item of equipment will be improved with the effector, so as not to cause distortions and other adverse effects. The equipment selected should be of a quality and reliability assured, prior preparation for possible malfunctions and effective and timely remedies. In some cases, preparatory work had to be completed a few hours before the performance, and although time was tight, every signal line had to be picked up in person for safety purposes. The problem with the conference system is characterized by high noise, a high level of distortion, irregular electricity levels, uneven frequency, imbalance in the proportion of voices, and misalignment.

As an auxiliary element in the performance of theatre art, stage sound plays a role in creating the situation, reproducing the atmosphere, advancing the situation, characterizing the person. The shanxi stage has a reasonable price
Composition of professional sound systems
1. Sound modulation and sound source equipment
Sound source equipment, including microphones, singers, box (disc) recorders, lasers (cds), tuners and karaoke machines, are used to provide a variety of audio signals. The transducer is the command centre in the sound system, which is capable of receiving and processing audio signals from multiple circuits, different levels of power, as well as of mixing and re-allocation and grouping, and of having multiple output ends that provide audio signals to the lower level. The console also has ***, signal display and speech functions。
Signal processing component
Sound signal processing equipment is also known as audio signal processing devices, including balancers, compressors/extensors, timers, noise-mitigators, hearing incentives, etc. The purpose and function of these devices is, on the one hand, to trim the signal for the sound colour to be glorified; and, on the other hand, to improve the quality of the channel itself with a view to improving the noise ratio and reducing distortion。
Output part of the 3 sound system -- power amplifiers and speaker
Power amplifiers are an important unit in the professional sound system. The audio signals from the modulates are processed by compressors, equalizers, incentives and sent to the power amplifiers, which magnify the audio signals to boost the soundbox and send the sound into the sound field。
Soundboxes are an important and integral part of professional sound and are one of the individual units of ** because sound in different structures have different styles, different characteristics and different sound effects. Soundboxes typically consist of three parts: loudspeakers, frequency splitrs and boxes。
