Problems solved by technology

[0002] At present, the technology and form of stereo recording and playback are developing from stereo to surround sound. Many multi-functional performance venues have also made continuous attempts to sound reinforcement, striving to achieve language sound reinforcement, replay music and various environmental effects. However, due to different types of dramas, users have different habits and interests, and the usage conditions cannot be unified. Especially in the case of fixed installation, once the installation is completed, it cannot be changed, and it is difficult to successfully complete the performance of various programs.

Embodiment Construction

[0010] as follows figure 1 Shown is a specific sound reinforcement mode with 3D8-X type, which is just one of the realization forms. The system is divided into two parts, above the dotted line is the part of the main sound reinforcement system, and below the dotted line is the part of the environmental effect sound system. Each of the two parts uses a mixer (if the number of output groups of the mixer is more than 24, it can also be realized by using a mixer, preferably a digital mixer), and the main mixer is responsible for Signal input from music, singing, speech or live effect sound, the environmental effect sound mixer is mainly used to adjust the environmental effect sound from the multi-track recorder (or digital audio effect sound workstation), and then replay it to each 21 channels or even more PA channel. The three sound reinforcement channels of the main sound reinforcement system, left, center and right, through the digital audio matrix that can be expanded infini...

Abstract

The 3D8-X is a stereo amplifying system. The normal amplifier L-M-R three main channels increase 18 surrounding-effect channels: front-left, mid-left, back-left, front-right, mid-right, back-right, mid-back, right-back, left-back, mid-back, back-right surrounding-effect sound, front-ceiling, mid-ceiling, back-ceiling surrounding-effect sound. Three main amplifier channels contain sub-low-frequency passage. All these make up the basic language and music amplifier. Besides every loudspeaker of this system is independent, and every power amplifier of loudspeaker may be controlled and programmed by their independent output channel, every loudspeaker may be controlled by their organized group set according to the surrounding-effect of loudspeaker or power amplifier to decide these channels. Then they can improve the effect of any show on the stage freely to make the programmers voice better.

Description

Technical field [0001] The present invention relates to a 3D8-X type 21+1+(extended) channel stereo mode. A form of use, mainly used in large-scale performances and performance venues that require performances of various types of dramas and playback of various environmental effects. Background technique [0002] At present, the technology and form of stereo recording and playback are developing from stereo to surround sound. Many multi-functional performance venues have also made continuous attempts to sound reinforcement, striving to achieve language sound reinforcement, replay music and various environmental effects. However, due to different types of dramas, users have different habits and interests, and the usage conditions are not uniform, especially in the case of fixed installation, once the installation is completed, it cannot be changed, and it is difficult to successfully complete the performance of various programs. In this case, in order to meet the needs of mod...
