Embodiment Construction

[0010] as follows figure 1 Shown is a specific sound reinforcement mode with 3D8-C 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 output grouping of the mixer is enough for 8 channels, it can also be realized by using a mixer), and the main mixer is responsible for the output from music, singing, speech or live effects. The sound signal input, the environmental effect sound mixer is mainly used to adjust the effect sound from the eight-track recorder, and then replay it to the 4+1 sound reinforcement channels. The left and right of the two sound reinforcement channels of the main sound reinforcement system, through a mixing device, such as an audio matrix processor, together with the two channels of environmental effect sound, complete the fo...

Abstract

Two environmental sound effect channels are added into the system which already has had left and right sound channels, the two environment sound effect channels are left and right; the two main channels including low frequency channel is used for implementing basic language and musical amplifying. The two environment sound effects channel is used for implementing multi environmental sound effects.

Description

Technical field [0001] The present invention relates to a 3D8-C 4+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: 03137962.1). , It is mainly used in performance venues or entertainment venues 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 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 installati...
