BARTEC VODEC VA300/CAGE-M is a 6 unit high standard 19 inch rack mount low profile assembly designed to carry up to eight amplifier modules. The unit comprises of a robust extruded lightweight alloy frame enclosure and motherboard “back plane“ printed circuit card equipped with eight slots. The back plane is fitted with eight gold plated indirect edge connectors, one per slot, which eliminate troublesome hard wired connection looms and allow rapid plug in/out amplifier capability to assure speed of service. The back plane carries an on board non volatile processing sub-system that enables amplifier eight to substitute any one of the other seven VA300/CAGE-M slots in the event of on-line amplifier trouble. Configuration also allows slot four to support hotstandby amplifier execution. In this case amplifier number 4 is a hot-standby for amplifier 1 to 3 whilst amplifier number 8 is a hot-standby for slot 5 to 7 or 1 to 7. An auxiliary supervisory group fault report output is available to extend VA300/CAGE-M Amplifier module warnings to the host Public Address management hardware.
The VA300/CAGE-M is enhanced to capture and report detailed operational information in real-time and when connected to M Class infrastructure all this information is available to a remote server, which logs and displays data as required. The VA300/CAGE-M gathers data from any VA300+M Amplifiers which are connected to it and routes that back to the M Class server.
