Abstract

The invention relates to a digital amplifier server based on a public amplifier server. The digital amplifier server is technically characterized by comprising a mother board, a man-machine interaction device, a power supply module, a main control module, a constant-voltage audio output module, a main power amplifier module, a standby power amplifier module, a noise detecting module and an audio input module. The power supply module, the main control module, the constant-voltage audio output module, the main power amplifier module, the standby power amplifier module, the noise detecting module and the audio input module are installed on the mother board through mother board connectors. The man-machine interaction device is connected with the mother board. The digital amplifier server is reasonable in design, uses the module design to greatly reduce system complexity and enhances system reliability. Meanwhile, a CobraNet network audio protocol is utilized, audio is in digital form in a transmission and switching process, the tone quality is prevented from being damaged, and the signal transmission quality is improved. The digital amplifier server has the advantages of being simple in structure, convenient to maintain, convenient to use and the like.

Description

technical field [0001] The invention belongs to the technical field of public broadcasting equipment, in particular to a digital power amplifier server based on a public broadcasting system. Background technique [0002] In a traditional analog public address system, audio post-stage equipment usually includes on-site broadcast controllers, emergency broadcast controllers, power amplifier detection controllers, power amplifiers, sequential power supplies, line detection devices, lightning protection devices, noise detection controllers, post-stage Monitoring devices and other devices, such as figure 1 shown. The above-mentioned system mainly has the following problems: (1) There are many audio post-stage devices, the system wiring is complicated, the construction is difficult, and the fault is not easy to troubleshoot; (2) The audio signals between the devices are all analog signals, which will cause serious attenuation and distortion during transmission, resulting in broad...
