Description
EST–CU-11LCD Control Unit (CU) is a matrix mixer of input signals which routes to 4 100 V internal audio buses, a 45-channel digital system buses or directly to audio outputs in a unit. EST-CU-11LCD is designed to work for small PA & VE systems or as an extension unit in more complex systems. It means that the CU can function independently as the central unit of a small system or be part of a large complex system for which it represents another level of either territorial extension (operation in a remote structure) or functional extension (operation of further fire zones and loudspeaker lines in such a structure). The modular design of the CU and its flexibility enables optimization of equipment and cost efficiency regardless of size / number of structures, their location and connectivity. In the event of losing connectivity with a networked master unit, EST-CU-11LCD is able to perform fire alarm scenarios independently thanks to the configuration recorded locally. While attached to the main communication ring of the system, EST-CU-11LCD can control amplifiers and power supply managers as well as receive alarm and digital signals; and send them to other system devices. EST-CU-11LCD Control Unit distributes audio signals to individual zones and ensures that individual zones function properly. It also controls the condition of loudspeaker lines and amplifiers. If a fault is detected, it sends the signal to the system and automatically switches to a backup amplifier. The CU is equipped with an EST-cAudIO-4/12 card offering 4 symmetrical line audio inputs and 12 symmetrical outputs to lead audio signals out to external devices or amplifiers of the EST ENT VES system. Furthermore, EST-CU-11LCD can be equipped with an LCD touch screen with a control module, which allows easy access to management functions and monitoring of the whole system – such extended configuration is included in EST-CU-11LCD Control Unit.
