Bogen s RIO1S is a multi-functional module with a priority-controlled relay contact, transformer-balanced input, transformer-balanced output, and an RJ11 output for direct connection to the override input of a zone paging system. The RIO1S provides a convenient way to integrate a Power Vector amplifier with a PCM zone paging system, allowing full use of the Power Vector s priority structure in zone paging applications for more sophisticated paging capabilities. Transformer-isolated, balanced line-level input 600-ohm or 10k-ohm (jumper selectable) input impedance Transformer-isolated, balanced line-level output 8-ohm, 0.75W output Input and output level controls Relay responds to jumper selectable priority level N.O. or N.C. jumper-selectable relay contact External control of priority muting buses Input can be muted from higher priority modules, with signal fade back Output (normally gate) can be synched with priority relay operation Output gating can be defeated via jumper RJ11 connection with line output and dedicated N.O. relay contact (allows easy connection to O/R port of Bogen telephone paging interfaces)
