RCF has released the DXT 9000 digital voice alarm system – ‘with the brains of network technology and the soul of professional audio’. This is a distributed system in which every component, including the loudspeakers, has its own physical address, can be monitored according to the latest EN 54 standards, and can be configured after installation where necessary.
The first fully digital PA/VA system to be designed from the ground up by RCF engineers, DXT 9000 voice-evacuation system is completely scalable and is suited to use in almost any kind of application, from the smallest school or hotel to huge campuses that include multiple buildings.
While paging and voice-evacuation are the primary uses, the DXT 9000 can also be used to interface pro-audio active speakers through RCF’s RD-Net control and monitoring system. Active loudspeakers can be combined together with 70V/100V line amplifiers on the same dedicated network, and all system amplification is class-D+ (unique to RCF) promising industrial-grade reliability, high efficiency and audio quality and a small installation footprint.
For maximum flexibility, the DXT 9000 boasts a double-ring topology. The first, simple ring is designed for small and medium-sized systems, while the second ring is for larger projects. Whatever the size of the system, all components are designed to be plug-and-play and set-up is easily configurable.
All digital amplifiers and active components are connected using RCF’s Flexicomm bus technology, for the most efficient use of available network bandwidth. For ease of installation, the majority of connections use twin-pair or four-pair J-Type fire-rated cable, while fibre-optics can also be used for longer distances, where the DXT 9000 can run over LAN or TCP/IP networks.
In the event of a failure in the input stage of the digital network, a Fall Back feature automatically allows the DXT 9000 to receive a signal from a dedicated fire base-station microphone, ensuring that the safety of the protected facility is never compromised.
‘From the word go, our goal was to design a voice-evacuation system that offered all the benefits of modern network technology – scalability, ease of configuration, reliability and full compliance with EN 54-16 standard,’ says Antonio Ferrari, RCF Market Manager for Audio Contractor. ‘We also plan to introduce several new EN 54-24 speaker models in the future; some of them represent innovative aspects in order to offer complete solutions according to the RCF philosophy. RCF Engineering Support Group is always available to support consultants and contractors to find together the best possible solution according to the requirements and constraints.
‘However, we believe we have also achieved something more: a VA system that benefits from a pro-audio approach, and which offers sonic performance that is more akin to that of a pro-audio setup, rather than a 100V line system.
The range of components available is already extensive and includes a choice of two master units, MX 9500 and MU 9186 (the former with amplification built in, the latter without amps), three monitored class-D+ digital power amplifiers (1 x 500W, 2 x 250W, or 4 x 125W), three paging mics (multi-zone, selective call and eight-zone extension) and the TS 9918 remote level control and program selector.
