- Main Features:
- The INOmini 679 is a sensitive, DSP-based (SDR) radio that receives standard FM analog and FM/HD Radio broadcasts.
- Stays on-mode and on-channel through signal and power loss; does not blend between FM and HD.
- Easy front-panel setup uses jog-wheel menu navigation with a large LCD display. Accurate, hi-res metering shows RF signal and audio levels, RBDS/PAD data and reception metrics. Critical system menus are hidden.
- 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 HD Reception Loss, Low Signal and Audio Loss.
- ‘Split Mode’ audio monitoring aids transmission diversity delay setup.
- The LCD displays RSSI, SNR, Cd/No, Multipath and HD Level metrics to help with receive antenna alignment.
- When issued, free firmware updates are easily installed in the field.

- Program Audio Outputs:
- 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:
- HD Loss: Fixed metrics determine loss of HD Radio reception.
- Low Signal: Alarm and reset trigger levels are independently adjustable relative to the FM carrier level display.
- Audio Loss: Alarm responds to monitored service (FM or HD Radio). Alarm threshold is adjustable between 0dB and –40dB, and the alarm delay interval is adjustable between OFF and 120 seconds.
- Alarm “Tallies”: Individual open-collector 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.
- Power Requirement: 12VDC at 335mA; a universal 90-240 VAC inline switching power supply is included with the INOmini 679 receiver.
- Mounting Options: An optional rack adapter accepts up to three INOmini modules in a 1U, 19-inch rack space. The 679 also may easily be fastened to any convenient surface with two small screws.
