Abstract

The invention discloses a professional power amplifier with a DSP (digital signal processor) digital speaker processor. The professional power amplifier comprises a case, a front panel and a rear seal plate and is characterized in that a power steady-pressure plate, a power transformer, a power amplifier and a fan are arranged in the case, a DSP digital speaker processor, a signal input module, a computer interface module and a loudspeaker output module are fixed on the inner side of the rear seal plate, and the computer interface module is provided with an RS485 or USB (universal serial bus) port; the rear seal plate is provided with a power input socket, a power insurance tube socket and a radiating hole thereon; the front panel is provided with a DSP liquid crystal displayer, a volume control knobs, function selection keys and a power switch thereon. Compared with the prior art, the professional power amplifier has the advantages that installation space can be effectively reduced, funds for purchasing singular peripheral audio equipment are effectively saved, troublesome installation and debugging are omitted, convenience in management is achieved, the professional power amplifier can be connected with a computer, and the power amplifier can be better managed.

Description

technical field [0001] The invention relates to an audio processing device, in particular to a professional power amplifier with a DSP digital sound box processor. Background technique [0002] In sound system design, stage professional sound reinforcement, installation and debugging, and other applications, everyone is more or less for some reasons (such as: due to the sound field defects of the building in the sound reinforcement environment, use an equalizer to compensate for the purpose of sound frequency balance. ;In the sound reinforcement environment, multiple sets of speakers are often required for sound reinforcement. There is a time difference between the sound restoration of the compensation speaker and the main speaker, causing the sound to be out of sync. Through the calculation of the sound, the delay can solve this problem. So a delay device is used; when the microphone picks up sound, it is impossible to be a standard audio signal. If the signal is too small ...
