Micro intelligent public address system integrates such functions as playing, intelligent timing control, audio matrix, partition control, intelligent firefighting linkage, remote computer control as well as telephone and remote paging. Owing to its integral public address functions and individualized intelligent control functions, this address system can better satisfy demands of users of medium and small address systems, such as amplification at such public places as primary and high schools, medium and small plants, parks and square.

Features
A public address controller integrating has such functions as playing, intelligent timing control, audio matrix and partition control.
It has 5 timing programs. Each timing program is provided with 500 timing points for 7-day circulation. Each timing point is available for control of audio source selection, bell, built-in MP3, AM/FM, 2-way power source, 4 types of external peripheral audio sources (CD, tuner, socket and MP3 program player). The 5 timing programs are easy for switch-over.
