The Inovonics 568 SOFIA HD-Radio™ SiteStreamer+™provides analog, AES3-digital and AoIP-streaming audio outputs. It collects histograms of signal parameters and displays HD Radio™ album artwork, station logos and similar visuals via the Web interface.


Multiple stations can be sequentially monitored using the programmable StationRotation™ feature. The SOFIA 568 includes a built-in BandScanner™, a real-time clock and full SNMP functionality.

The elite SiteStreamer+™ (‘Plus’) series offers advanced features for the most critical monitoring situations.


SiteStreamers™ also deliver important RF and audio signal measurements and dispatch email or text-message alarms for out-of-limits conditions and other reception errors.

Inovonics 568 SOFIA HD-Radio™ SiteStreamer+™

    • Install the SiteStreamer within the reception contour of your station and monitor off-air analog FM or HD Radio signals (HD1-HD8) via the Web from anywhere in the world.

    • The built-in BandScanner displays a spectrum plot of the entire FM band (or a user-selected portion) and identifies HD Radio transmissions.

    • Gives local and remote readout of all pertinent FM/RDS and HD/PAD data.

    • Easy front-panel setup uses jog-wheel menu navigation and the front-panel readout. The corresponding Web interface offers a detailed presentation and additional options.

    • Stays on-channel and on-mode through signal and power loss; does not auto-blend between FM and HD like a consumer radio.

    • Front-panel alarms and/or rear-panel ‘tallies’ indicate Audio Loss, Low Signal, RDS Errors and HD Reception Loss.

    • ‘Split Mode’ audio monitoring aids transmission diversity delay setup.

    • When issued, free firmware updates are easily installed in the field or remotely through the Web interface.

    • The half-rack package features an OLED hi-res graphic display, wide-range LED level meters and individual alarm LEDs with rear-panel tallies.

    • Real-Time Clock has battery backup.

    • SNMP utility is fully supported.

    • GPOs may be user-assigned to specific alarm functions.

    • Fulltime off-air program audio is available simultaneously as L/R-analog, AES3-digital and Dante®-based AES67 AoIP streaming, all with adjustable levels, plus a multi-listener Internet IP stream and front-panel headphone jack.

    • The SOFIA 568 Internet-listening stream supports up to 10 listeners at once.

    • Enhanced alarm logging includes the duration of each alarm, and there is virtually no limit to the number of alarms that can be logged.

    • Download a complete log randomly, or automatically daily, weekly or monthly.

  • Tuning Range

    87.5MHz to 107.9MHz in 100kHz steps.

    Antenna Input

    75Ω (BNC).


    10dBµV required for 50dB mono-FM S/N.

    Audio Response

    • FM: ±1dB, 30Hz – 15kHz; de-emphasis is programmable at 75µs or 50µs or OFF.
    • HD Radio™: ±0.25dB, 20Hz – 20kHz.

    Reception Modes

    • FM: Stereo / Stereo Auto-Blend / Forced-Mono.
    • HD Radio™: HD1 through HD8; ‘Split Mode’ delivers L+R FM to the left audio channel and L+R HD1 to the right.

    RDS Fields Displayed

    PS, PI (and call), RT, RT+1, RT+2, PTY, PTYN, C/T, M/S, DI, TP, TA; RDS Block Error Rate, Groups Transmitted (with use statistics), AF, ODA.

    HD PAD Data Displayed

    • SIS: Short Name, Universal Name, Station ID, Slogan, Message, Station Location.
    • Misc: Service Mode, Codec Mode, TX Gain, TX Blend Control.
    • PSD (HD1-HD8, each): Slogan, PTY, Artist, Title, Album; Logo and/or Artist Experience graphics.

    Graphs and Metering

    L, R, L+R and L–R Program Audio; Audio Histogram; RSSI, RF SNR, HD Level and Cd/No levels and histograms.

    Program Audio Outputs:

    • Balanced Analog (XLR) Left and Right outputs are adjustable from –15dBu to +15dBu in 0.1dB steps.
    • AES Digital (XLR) output at 44.1kHz or 48kHz is adjustable from –30dBFS to 0dBFS in 0.1dB steps.
    • Headphone Jack (3.5mm TRS) has adjustable listening level.

    Streaming Audio

    MP3 or OGG (selectable) streams have bitrates from 32kbps to 256kbps and sampling rates from 16kHz to 48kHz.


    • Audio Loss: Alarm responds to the monitored service (FM or HD Radio). Alarm On/Off thresholds and Time On/Off intervals are programmable.
    • Low Signal: Alarm and reset trigger levels are independently adjustable relative to the FM carrier level display and have programmable Time On/Off timings.
    • RDS Alarm: Programmable Time On/Off for RDS Loss or PI Error.
    • Pilot Loss: Programmable Time On/Off for loss of Stereo Pilot.
    • HD Loss: Fixed metrics determine loss of HD Radio reception; programmable Time On/Off.
    • Email Alerts: Email or SMS/text-messaging can alert selected personnel to specific alarms.
    • Alarm ‘Tallies’: Individual open-collector NPN transistor outputs to ground are programmable for logic polarity and GPO assignment.

    Real-Time Clock

    Auto-sets to Internet time; auto/manual DST setting, battery backup.

    AoIP Port

    Dante®-based, AES67-compatible (selectable) AoIP utility has independent IP, Audio Format and Transmit Flow settings.

    LAN Port

    LAN connection to local network or Internet provides remote monitoring (listening and SOFIA 568 control); user-program­mable network setup and streaming parameters.

    Power Requirement

    12VDC at 450mA; a universal 90-240VAC inline switching power supply is included with the SOFIA 568 SiteStreamer.
