THIS PRODUCT IS NO LONGER IN PRODUCTION.

The 639 has been replaced by model 679.

The INOmini 639 is an FM and FM/HD Radio™ receiver for professional off-air broadcast monitoring. It receives standard analog-FM broadcast transmissions as well as FM/HD Radio™digital broadcasts transmitted ‘in-band, onchannel’ via the FM station’s associated HD1 through HD8 auxiliary digital broadcasting channels. Analog and digital FM programs are each accompanied by digitized text and housekeeping data. Analog-FM RDS (Radio Data System) and digital-HD Radio™PAD (Program- Associated Data) are shown on the INOmini 639 front-panel LCD display, along with incoming signal quality and other information. Additionally, RDS and PAD data may be accessed through the front-panel USB connector for computer analysis and logging.

A leading feature of the INOmini 639 is that it does not automatically revert to FM reception if the digital signal is lost. This is of critical importance to the broadcaster, but makes this product somewhat unsuited to general consumer use.

*Ask about our custom mounting rack that can hold up to 3 INOmini series modules in a 1U space.
