DXT 9000 is the logical evolution to the RCF DXT active matrix solution range. To design DXT 9000, RCF has developed a digital multi-platform where PA-EVAC systems join PRO-INSTALL systems in a completely scalable and versatile range of configurations and solutions. It allows very flexible system architectures, driving in the same way professional amplifiers and speakers, 100 V amplifiers and commercial audio or EN 54-24 voice alarm speakers equipped with line transformers. In this architecture, MU 9186R is the master unit with networking facility on-board; it is used when the system requires a distributed configuration where several MU 9186R and relevant slave amplifier units 9501 (1 x 500 W), UP 9502 (2 x 250 W) or UP 9504 (4 x 125 W) connected through the dedicated RCF-Flexicomm data-link port are part of a large installation with even hundreds or thousands of zones.
