Problems solved by technology

However, due to the limitations of various objective conditions, the 3D8 sound reinforcement system cannot be realized in every occasion, so it is necessary to propose a 3D8-A stereo sound reinforcement system under these circumstances.

Embodiment Construction

[0010] as follows figure 1 Shown is a specific sound reinforcement mode with 3D8-A 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 effect sound system. Each of the two parts uses a mixer (if the output grouping of the mixer is enough for 12 channels, it can also be realized by using a mixer), and the main mixer is responsible for the signal input from music, singing or speech , The effect sound mixer mainly regulates the effect sound from the eight-track recorder, and then replays it to each of the 6 sound reinforcement channels. The two sound reinforcement channels of the main sound reinforcement system, left and right, complete the sound reinforcement of 6 channels together with the 4 channels of effect sound through a mixing device, such as a matrix processor. according to figure 2 , image 3 Position the loudspe...

Abstract

This 3D8-A is a stereoamplifying system. Apant from the main amplifying system of L-R channel, it has four sound-effects passages, containing L-R surrounding sound system, front stage surrounding sound, stage-door surrounding sound, two main amplifier passages, a sub low-frequency passage to produce a basic language and music sound amplifier. The four surrounding passages improve sound-effects such as opera, stage play and any other shows on the stage.

Description

Technical field [0001] The present invention relates to a 3D8-A 6+1 channel stereo mode, which is another form of use for the 3D8 stereo sound reinforcement system (the 3D8 stereo sound reinforcement system has applied for a patent before this, and the application number is: 031379621). , It is mainly used in the open air or in performance venues or places where the 3D8 sound reinforcement system cannot be realized due to other objective factors. Background technique [0002] At present, the technology and form of stereo sound 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 the level of language sound reinforcement, replaying music and various sound 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 ...
