Public Address System
Throughout the world, sound diffusion has been greatly acknowledged as a veritable source of mass communication. This can be seen in motorways, in shopping centres conference halls or at sports venues. People expect to hear good speech and music at most sports venues or shopping malls.
BjFire Systems Ltd has been designing and installing Public Address System of varying degree for nearly ten years and therefore possess extensive experience and technical expertise in the selection and application of available equipment.
Our products are modular PA systems which take utmost advantage of recent advancements in sound reinforcement and diffusion and professional systems developed by RCF and other professional manufacturers.
These manufacturers have an established reputation for high products amongst corporate PA users the world over.
Key Benefits of Solution
- Cost-effectiveness – The Public address system solution we are offering are distinctly high performance cost effective systems with reduced installation and maintenance costs.
- Simplicity and Ease of Use: The systems are user friendly and do not need a high level of expertise to operate.
All-Round Support from BjFire Systems Ltd– The high quality systems from BjFire Systems Ltd are backed up with comprehensive maintenance, service and training support. The underlying considerations that run throughout the design of these systems include:
- Cost effectiveness,
- Adherence to stipulated standards,
- Aesthetics
- Building management and systems integration.
Design Consideration
The contexts in which the design process will take place have been defined in two categories:
- The Client’s requirements: The school auditorium and conference halls requires high performance Public address systems to be installed. The system will form part of an integrated security & entertainment system.
- The Characteristics of the site: The site requires high performance Public address system solutions that will take into cognisance the requirements of security. High performance Speakers and microphone will be installed.
Accordingly, our recommendations are based on the following:
- Size/Complexity of the project
- Flexibility required
- Degree of event management required.
Solution Overview
BjFire Systems Ltd is proposing an integrated solution for a vast range of applications from simple PA systems for Auditorium and conference halls. The unit incorporates a PA amplifier with constant voltage outputs for directly supplying speaker lines, microphone inputs for connecting announcement consoles, and a digital FM tuner with selection storage. The system is equipped
with a multiple-CD player with track/CD programming. It features a special input with independent volume control for connection to a supplementary sound source.
A master volume control and tone controls on all the inputs make it possible to adapt sound diffusion to your specific needs. Where the maximum power that can be delivered by the single units is not sufficient for driving all the speakers in the system, a special connector makes it possible to connect additional power amplifiers.
Sound Controller
The sound controller is a veritable system that controls a wide verity of audio signal inputs. These inputs include microphone, music source, fire alarm, local telephone exchange. It has the capacity to take 64 inputs simultaneously and can zone the outputs to 128 distinct zones. This means that announcement can be precisely directed to required areas and can be generally be broadcasted. The sound controller also has a monitor system that monitors the sound and connections from different sources as well as well as other systems connected to it.
These are devices that are attached to remotely mounted devices like amplifiers and speakers.
Amplifiers
These are used to step the signals that have been already in the system.
Loudspeakers
The loudspeakers are the diffusion sources. They are used to reinforce the sound that has been processed and amplified. BjFire Systems Ltd is proposing the optimum choice for live sound situations where an exceptional full range, outstanding bass reproduction and accurate high frequency delivery is required.
This also suitable for monitoring applications
Preamplifier-mixer
This has been designed to provide a flexible solution for any paging and music application in PA systems.
Recorder
Recording of speeches, delivering announcements, alarm messages, advertising spots and other audio events can be done.
