Description:CCA-15P/3 classroom amplifier feature: The classroom broadcast system outputs at 8 ohms by a 15W power amplifier and inputs by 1-channel MIC and 3-channel AUX with separate adjusting the volume of each channel. No matter the equipment starts or not, it will provide 100V fixed pressure input priority for broadcast. Because the system is flexible and is firm and durable, it is the first option for the equipped broadcast system in schools and other locations. AM-828 audio matrix feature: Free switch between 8-channel audio input and output is available by the equipment. 1V balanced input, 200mV and 500mV unbalanced input ports enable users to connect it with different signal sources (like CD, record, card jack etc audio sources). DC-816 digital controller feature: 1) With 16-channel intelligent control signal output and fire control centre linkage input port. Its capacity can be expanded by connecting other equipment. 2) With automatic fire control linkage function (broadcast zones are N, N-1, N+1). 3) Adopting digital signal transmission. After it collects, analyses and disposes the information of circumjacent equipment (such as RM-416 remote MIC, TI-603 telephone connector, fire control detecting head, etc), it will automatically inform the correlative equipment of the working status of system, carry out emergent fire control broadcast automatically or by hand, broadcast over subarea by phone, control the entire system by broadcast priority order of remote MIC. Meanwhile, working status of each channel is shown in the equipment and users can neatly control each zone according to his actual need by it. 4) It analyses and deals with the information to control EC-601 emergency switch and start corresponding audio channels. Meanwhile, it outputs short circuit and DC24V signals to control amps of corresponding zones as well as switch from audio control to forced switch priority status, then to carry out emergent fire control broadcast or sub area calling broadcast. EC-601 emergency switch feature: 1) Urgent forced switch; automatically start the internal record to broadcast when the short circuit signal or DC24V is input. 2) When the emergency happens, it will output a signal for activating the short circuit. 3) Fire fighting and siren are carried out by connecting the internal communication port and the matched equipment (like digital controller DC-816). 4) Recording function. automatic fire fighting broadcast is carried out by recording the needed into the internal phonetic chip. 5) Seeking broadcast over zones inside the system by combining the matched mike and DC-816 operation. 6) Test function means to carry out the system test or the emergent broadcast maneuvering. 7) Operation mode: record, test, automation.
