The PRO Series 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 PRO Series Control Centre.

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 PRO Series DL351 stage box, and/or other AES50 I/O hardware. It is also possible to use any PRO Series with DL251, DL351, DL451 and DL431 plus 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.
