Linear array audio power amplification device

Abstract

The invention relates to a linear array audio power amplification device which comprises an audio transmission interface module, a DSP audio processing module, a control interface module and a power amplifier module. The DSP audio processing module is connected with the audio transmission interface module, the control interface module and the power amplifier module. The DSP audio processing moduleis an 8-input 16-output DSP audio processing module; the DSP audio processing module comprises eight transmission links; each transmission link comprises an audio signal source selector , a noise gate, an input gain, an input delay, an input phase, an input high and low frequency lifter, an input nine-segment parameter equalizer, an input RMS amplitude limiter, an input mute switch, a channel router, an output gain, an output delay, an output phase, an output RMS amplitude limiter, an output limiter, an output eight-segment parameter equalizer, an output high and low pass filter, an output FIR filter and an output mute switch which are connected in series.. The high and low pass arranged in the eight transmission links are connected with one another. A purpose of integrating multiple functions is achieved.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a linear array audio power amplifying device. Background technique [0002] The full name of the line array power amplifier is a line array audio power amplifier. It is a power amplification device used to drive multiple array speakers to reproduce the sound. It is suitable for most speaker units. The traditional linear array audio power amplification equipment can only realize the function of sound amplification, and needs a lot of external equipment to realize other functions. For example, when a professional performance system needs to be formed, some auxiliary equipment, such as signal processors, control , Display and various types of ports and other equipment, devices, and complicated signal transmission lines, bring very cumbersome operations and work burdens to users. It can be seen that the traditional linear array audio power amplification equipment has the pr...
