Public Addressing

Public addressing, even though is communication system, we have categorised in life safety system. Effectively addressing and communicating with people in case of emergency is the most important aspect which will save n number of life. For normal usage these system can be used to address people in offices or factories at large, but to communicate an emergency message at once to all is the prime goal of a PA system. Specially in a public places e.g. hospitals, government offices, auditoriums, movie theatre etc where people are not so familiar with the building structure, PA systems can effectively guide them to safety. With integration with the automatic fire alarm systems, PA systems can become even more effective as they can deliver automatic evacuation messages.

We offer range of PA system solutions from conventional PA system to new IP based announcement systems. We design PA systems for various types of buildings and scenarios.

Below is the range of products we offer in PA system.

Ceiling Cone Speakers

The basic type of speaker, widely used in a all addressing system are popular for various types of installations specifically in office areas. Ceiling speakers gets concealed in false ceilings, hence improving the aesthetics of the room. With a moderate frequency response both voice and music can be played easily on these speakers. Ceiling Cone Speakers speakers comes with 6W rating with tapping to reduce the wattage for saving power and increasing per loop speaker quantity.

Box Speakers

Box speakers are cone speakers enclosed in a protective housing, generally made of wood or hard plastic. Areas where cone speakers installation is not possible or more watts speakers are required, box speakers are used. They are installed in office areas, factory space etc. they also saves on cabling. Outdoor box speakers are used in parking or similar applications.

Horn Speakers

Horn speakers delivery more sound wattage, and project sound to much longer distance due to the design. Horn speakers are usually installed in noisy areas like factory, railway or bus stations or open gatherings.

Line Array

Line array are specially designed set of speakers, arranged in a specific pattern to give maximum sound output & more area of coverage. Applications like stadiums, auditoriums are the ones which requires line array speakers to cater for public announcements to large crowds. Frequency response of line speakers are also better than the normal PA speakers, hence high quality music can also be played on them, e.g. at a cricket stadium in a IPL match.

Call Stations

Call stations deliver the voice to the speakers. Call stations comes with zone selections to divert your sound to a specific area or zones as they are called. Call stations also can send audio to all zones at once. With zone modules, call stations can be expanded as per the required number of zones.

PA Controllers

PA controllers are the heart of properly designed PA system. It controllers the audio signal paths from a call station to the speakers zones. It can be integrated with 3rd party system like fire alarm system for automatic evacuation messages in case of fire. It can be integrated with office EPABX system so that office telephone can act as call stations. Usually PA controllers comes with a 6 zone support.

Routers

PA controllers generally has limitations of supporting 6 zones, but many installation demands more number of speakers zones. Also due to the building structure or plant layout, cabling to all zones from a single controller is difficult or expansive. Routers are the devices which can solve these problems. They are basically zone expanders which can be installed at different locations and communicate to the master controller via a RS485 or TCP/IP communication protocol. Number of routers can be connected in a PA system, hence expanding the PA system as per customers requirements.

Amplifiers

Amplification of low power audio signal from the microphone if the basic process of any audio or sound system. Depending upon the number of speakers, power requirement is calculated and accordingly amplifiers are selected. We provide various kind of amplifiers from low wattages to 1000 watts. If power demands are increases these amplifiers can also be used in cascading topology.
