Audio Visual (AV) Systems

AV systems are used to switch, distribute, stream and control a wide variety of communication signals from multiple sources to any destination while maintaining signal integrity and ease of integration in a wide variety of applications. These products include graphical user interfaces (GUI), switchers, configurable control systems, distribution amplifiers, signal processing equipment, streaming codecs, and high resolution cables. Additional audio products include speakers, digital signal processors, and amplifiers. Our custom applications can be implemented in corporate boardrooms, presentation/training centers and university lecture halls, government buildings, healthcare facilities, retail locations, themed entertainment venues, courtrooms, broadcast venues, houses of worship and theatrical stages. ETI has a professional AV engineer on staff who can provide a solution to exceed your expectations within your budget.

Lehigh Career and Technical Institute
LCTI, located in Schnecksville, PA, is one of the largest technical schools in the country. The institute houses individual classrooms and large lab settings for teaching a wide variety of technical and industrial trade classes. LCTI needs to be able to contact students and faculty in the classrooms and lab areas with public address announcements as well as time coordinated tones for the start and end of classes.
LCTI needed a way to communicate with these individual classrooms, lab areas and corridors with mass notification in the whole building and campus buildings. The system will require the take-over and control of speakers connected to individual sound systems used in the cafeteria and restaurant areas. These public address announcements needed to be coupled with a synchronized clock and coordinated time tone signaling system.
ETI proposed a solution to replace the existing paging system with an individually addressable public address system. This system allows for individual classroom communication as well as multi-zoned public address announcements. The solution also accommodated the low power requirements of the individual classroom speakers as well as the high power requirements of the lab and corridor speaker areas. The communications system allowed for mass notification to all areas and all campus buildings, including the individual sound systems of the cafeteria and restaurant areas. The system also included a redundant system as a back-up, should the microprocessor system fail. The communications system was integrated with a campus-wide synchronized corrective clock system and time coordinated tone signaling system. Finally, the system was interconnected to the LCTI’s voice over IP telephone system to allow classroom, lab, and mass notification announcements to be made directly from the administration staff telephone sets. This system solution added to the security and safety of the students attending LCTI.
