Description

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.

Program Audio Output(s)
Balanced Analog (XLR) Left and Right outputs are adjustable from -15dBu to +15dBu in 0.2dB steps.
Balanced Analog (XLR) Left and Right outputs are adjustable from -15dBu to +15dBu in 0.2dB steps.
AES Digital (XLR) output at 44.1kHz is adjustable from –30dBFS to 0dBFS in 0.2dB steps.
Headphone Jack (3.5mm TRS) has adjustable listening level.

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.

Mounting Options
An optional rack adapter accepts up to three INOmini modules in a 1U, 19-inch rack space. The 673 also may easily be fastened to any convenient surface with two small screws.
