Overview
The INOmini 673 is Inovonics’ second-generation, small form-factor FM broadcast monitor for professional applications.
A sensitive and selective off-air receiver for standard analog-FM broadcasts, it has application as a ‘confidence monitor’ or as a rebroadcast receiver in FM translator service. The 673 decodes and displays the most important data from RDS/RBDS data groups as well.
The INOmini 673 gives front-panel and remote alarm indications of program and RDS transmission errors. It can also deliver a high-quality audio feed for program distribution throughout the broadcast facility with adjustable analog and AES digital audio outputs.
Features
-
This sensitive and selective DSP-based (SDR) receiver has extended band coverage down to 64MHz.
-
Easy front-panel setup uses jog-wheel menu navigation with a large LCD display. Accurate, hi-res metering shows RF signal and audio levels; critical system menus are hidden.
-
Front-panel display of most-essential RDS/RBDS information including RT+ ‘tagging’ data.
-
Balanced analog and AES-digital program line outputs are available simultaneously; levels are independently adjustable.
-
Flashing-red front-panel alarms and rear-panel ‘tallies’ indicate RDS Loss or PI Error, Low Signal and Audio Program Loss.
-
All receiver setup parameters are held in non-volatile memory.
-
When issued, free firmware updates are easily installed in the field.

Front-Panel Red-Flashing Alarms
- RDS: Alarm signals the loss of RDS data or font panel alarms; an error between the received PI code and a user-programmable PI code entry.
- Low Signal: Alarm and reset trigger levels are independently adjustable relative to the RF signal level display.
- Audio Loss: Alarm threshold is adjustable between 0dB and –40dB, and the alarm delay interval is adjustable between OFF and 120 seconds.
- Alarm “Tallies”: Individual opencollector NPN transistor outputs to ground are programmable for logic polarity.
USB Port
The front-panel mini-USB port allows the quick uploading of firmware updates when issued.
