Audio cabinets will include a VX123-A 4-Door audio switching card and video cabinets will include the VX123-V 4-Door video switching card. Each switching card requires 12VDC power and will be pre-wired from one of the 12VDC outputs on the UBPSU5.0 PSU. It has four fused (fitted with a 1A, 20mm ‘quick blow’ fuse) door input/output terminals that includes a status LED to indicate when there is a fault with the input/output (when the LED is ON this indicates the input is ok, when the LED is OFF this indicates the fuse is damaged or blown).
