INOmini FM/RDS Monitor Receiver


The INOmini 633 is a sensitive and selective FM and FM/RDS receiver for professional applications. It receives standard analog FM broadcast transmissions and works as a ‘confidence monitor’ or as a rebroadcast receiver in FM translator service.

The 633 also decodes and displays data from RDS/RBDS data groups. The front panel USB port supplies a raw RDS stream to be used with the supplied software and any PC for further monitoring, logging, qualification and analysis of the RDS/RBDS data groups.

In addition to essential alarms the front-panel LCD display is host to numerous menus, enabling easy setup and display of both signal quality and RDS information.
