Abstract
The invention provides a stage audio control system. The stage audio control system comprises a main control unit and a sound amplification unit; the main control unit comprises a main control module; the main control module is connected to a pre-amplifier; the pre-amplifier is respectively connected with an audio distributor, a multi-channel digital playing host and a volume controller; a constant-pressure power amplifier is connected with a partition controller; the sound amplification unit comprises a patch panel; a sound console and a digital audio processor are connected onto the patch panel; and a feedback suppressor is connected between the sound console and the digital audio processor. According to the invention, by means of mutual matching between the sound amplification unit and the main control unit, unified allocation of a plurality of loudspeaker units in a stage sound system is realized; the system is low in power and distortion and simple to debug; simultaneously, the working stability is high; multi-channel working can be realized; the control system is simplified; the cost input is reduced; security and maintenance are also convenient; furthermore, wireless wiring is partly adopted; and thus, the stage audio control system is simple, rapid and high in expansibility and has wide application prospect.
Description
Technical field
The present invention relates to stage sound effect technique field, be specifically related to a kind of stage audio control system.
Background technology
Current stage sound effect system generally can comprise multiple loudspeaker unit, in order to realize predetermined sound effect, as follows to the conventional adjustment System of the stage sound effect system that multiple loudspeaker unit forms: (1) first adjusts input processing parameter and the output processing parameter of the audio signal processing unit of single loud speaker; (2) effect of stage sound effect system is tested, adjust with the audio signal processing unit parameter of further refinement test data to associated loudspeaker by rule of thumb; (3) again the whole structure of stage sound effect system is tested, according to test result, again the audio signal processing unit parameter of loudspeaker unit is adjusted.That is, for realizing preferably system acoustic effect, needing constantly according to overall acoustic efficiency, repeatedly the parameter of the audio signal processing unit of each loud speaker being adjusted.
Because the equipment of stage public address is many, therefore connect cumbersome, just more difficult in build process, can not combine arbitrarily sound equipment, can only the corresponding corresponding stereo set of sound reinforcement system, have to increase sound amplifier to reach better good effect, make the sound amplifier of stage many, in use some equipment also also exists the phenomenon of distortion simultaneously, the effect of original tonequality can not be shown, go wrong to not allow the sound reinforcement system of stage, audition will be carried out in build process, make it can not occur unnecessary problem in normal use procedure, result of use is not high enough, the module of power amplifier is more single, when peripheral signal has multiple input, can only then send into sound reinforcement system by peripheral signal changing system and public address is carried out to signal, make the system of integration stage various, cause connecting complexity, occupy stage space.
Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
