Plenty of power supply. 32 pieces of 10000microF for  each channel.
 
 
State of the art technology multi- stage power supply circuitry are used for PA 3U amps. This method reduces heat and greatly improves efficiency of the amplifier, which leads to an excellent stability and durability.
 
Multi- protections: PA 3U equipped protection of full short circuit, thermal, RF, On/off muting, DC- fault power supply shutdown and soft start.
 
A built- in intelligent Clip function. It has a broad range of signal input (0dB 8.5V). Even the CLIP LED lights up a long time in an unexpected situation.
 
Muti-speed cooling fans installed. It works faster along with the rising of amplifier temperature. This avoids some mechanical noise in quiet environment.
 
PA 3U can work stably at 2ohm condition for long period. It is a breakthrough in traditional high power amps in the industry.

The Public Address System offered is meant for independent two-way communications network in the industrial plant Functionally, the different process unit and offsite areas of an industrial plant will be inter connected with the central control room through this communication network There are two modes of communication viz. PAGE to address large area and PRIVATE to hold conversation.
 
The following communication can take place in the system:
 
A. Communication between the Field Call Stations (FCS) with the help of Master Control Unit (MCU).

B. Communication between Master Control Unit (MCU) and Field Call stations (FCS).

C. Communication between EPABX subscribers with the Field Call Station through EPABX Interface.
 
The P.A. System network mainly comprises with the following items:
 
 1.  Central Exchange (CE)
 2.  Master Control Unit (MCU)
 3.  Field Call Stations (FCS) with accessories (J.Boxes and loudspeakers)
 4.  Cables for interconnection.
 
Central Exchange (CE)
 
The central control exchange is a microprocessor controlled exchange.
The central control exchange is a free floor mounted 19" rack. The cables from field stations and master control station are terminated on the termination PCB's and terminal blocks, easily accessible from the rear of the rack. The detachable gland plate is provided at the rack bottom, which can be removed & holes punched to facilitate the entry of cables. All the cards / modules sitting inside the rack are distributed in sub racks and all these cards/modules are plug in type giving a modular structure. It is very easy to add some cards for further expansion. The Central Control exchange is 16/32way operate with Master Control units (1 No.), 24 Nos. Zones and EPABX interface (1 no.).
