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 architecture, driving in the same way professional amplifiers and speakers, 100V amplifiers and commercial audio or EN 54-24 voice alarm speakers equipped with line transformers. In order to grant a high installation flexibility and output power on a larger number of zones, DXT 9000 includes three models of RCF ClassD+ power amplifiers, able to deliver up to 500W on 100V or 70V constant voltage speaker lines. In mid-large size systems, models UP 9501 (1 x 500W), UP 9502 (2 x 250W) and UP 9504 (4 x 125W) can be connected to both MX 9502, MX 9504 and MU 9186 through the dedicated RCF-Flexicomm data-link port. DXT9000 system allows for spare amplifier facility management. UP9501 model can be programmed to become a hot stand-by unit for one or more main power amplifier, and automatically replace any of them in case of fault.
