API 500V Vertical 10 Space Rack


The API Model 500V is powered externally by a tri-polar power supply and is designed to accept many different API standard format 5.25" X 1.5" modules. The 500V comes internally wired for PIN 2 hot. An external dual 16 volt power supply can be used, or the API 200PS can be purchased. The input/output jacks are both XLRs. The 500V can hold up to ten API modules, regardless of the "era".

The 500V comes internally unwired, allowing a facility to wire the module inputs and outputs, nominal levels, and special interface functions to the rear panel XLR connectors. The rack is also available wired to any specifications.

The 500V can be ordered with an optional 48 volt phantom power supply, bussed to pin 15 for the API 512C to access. It must be noted that the older API 560A series equalizers used pin 15 for a "direct output" and must be disabled on the 560A circuit board edge connector by cutting a trace. This will eliminate 48 volts from damaging the 560A series equalizers.

API makes several modules to fit this rack, including the 550B, 560, 525, and 512C. These modules are designed to help expand existing limited input console configurations, allowing a facility an option to a larger console.
