The PRO3, PRO6 and PRO9 processing engine is a 7U 19” rack mount unit, which houses up to 7 audio processing modules and routing hardware. Employing advanced FPGA architecture, it has three removable power supplies, only two of which are required for full operation. The power supplies are auto-voltage sensing, auto-switchover, hot-swappable, are fitted with locking AC connectors and are identical to, and therefore interchangeable with the PSU’s in the Control Centres.
The engine has dual-redundant HyperMac ports (both CAT-5e and Optical on the PRO6 and PRO9) which provides the digital equivalent of a 384-way (192 in + 192 out) multi-core between the stage and FOH. There are also eight AES50 ports, which facilitate connections to the DL451, DL351 and DL251 stage boxes, and/or other AES50 I/O hardware. It is also possible to use a PRO3, PRO6 or PRO9 with a DL431, the KLARK TEKNIK DN9696 Hi Resolution Audio Recorder and DN9650 Network Bridge.
The processing engine is loaded with 4 modules for a PRO3, 5 for a PRO6 and 6 for a PRO9 in the standard configuration, with an extra-cost option for an n+1 redundant spare module.
