As one of the most importance role in the whole public address system and as the main thrust of sound transmission, the main function is the audio signal amplification and joined carrier, which will have a carrier sound signal is issued.
Please pay attention to below point :
1. Whether the thermal performance of the PA amplifier can reach or not.
2. Whether the thermal protection device is a conventional tubular fuse. In order to facilitate and to select reset type insurance breaker, this kind of protection device is as a reference to the current generated by the temperature, the temperature only reach a certain degree,the dual metal sheet produces bending, will achieve the protection effect; in this way the machine is unable to provide the exact conservation of, so it is recommended to use conventional tubular fuse, reaction time fast enough to play to the protective effect.
3. Although the PA amplifier is just one parts in the whole public address,but it is the one we can not ignore.It also plays the important role in the whole system.
