    Section II INSTALLATION GENERAL This section of the manual addresses the physical installation of the 552 at its operating location, the ‘nuts and bolts’ of con- necting the unit. This section also references pages where per- tinent setup options and adjustments are discussed. As soon as the equipment is received, inspect carefully for any Unpacking and shipping damage.

    The 552 employs an internal ‘universal’ switchmode power AC Mains Power supply that accommodates mains voltages between 88V 264V Certified self-protection circuits have replaced the once-familiar fuseholder. The supplied detachable IEC-type power cord is fitted with a North-American-standard male plug. If you need to replace the mains plug with another, you will find that the individual cord conductors are color-coded in one of two ways.

  • Page 19: Bringing Up The Webpage Server

    BRINGING UP THE WEBPAGE SERVER To access the 552 Webserver interface, both the 552 and your Network computer must be on the same Local Area Network (LAN). As Considerations promised, the 552 can be accessed from a computer, tablet or phone anywhere in the world, but first your network needs to be set up to make this possible.
  • Page 20: Section Iv - Using The Web Interface

    Section IV USING THE WEB INTERFACE The Inovonics 552 includes an internal Webserver that contains Internal multiple interactive pages, or menus, for setup and operation Webserver of your unit. These pages give ready and interactive access to all settings, readouts, graphics, audio monitoring and alarms.

    A list of all the Webpage menus can be found at the left edge of The Menu List any page. Click on any menu heading to go immediately to that Webpage. The ‘responsive’ 552 internal webserver provides an optimal ‘Responsive’ viewing experience across a wide range of devices: desktop Webpages computers, tablets and mobile phones.

    Tuning the 552 This snapshot shows the Tuner subsection of the Now Playing Webpage. In this example the 552 is tuned to Los Angeles sta- tion KLOS at 95.5MHz. This station carries HD1, HD2 and HD3 programs as indicated in the heading. Tune the 552 by any of three methods.

We recommend the more conservative default value, but it’s your call. You should typically see negligible difference between positive and negative deviation readings, reflecting only the asymmetry normally encountered in speech and music waveforms.

    Demodulated FM Audio This metering area displays the demodulated FM program au- dio. Left and Right channel levels have quasi-peak response and a quick fallback for better visualization of instantaneous vs. av- erage program energy. Keep in mind that these meters in no way approximate “VU”...
  • Page 29: Itu-R Bs.1770 Loudness Measurement

    The 552 incorporates a program loudness measurement utility ITU-R BS.1770 based on (human) ‘perceived loudness’ per the ITU-R BS.1770 Loudness Standard. Meter readings under this standard are expressed in Measurement “LUs” (Loudness Units), one LU equivalent to 1dB. ‘Zero-LU’ does not conveniently correlate to a specific modula- tion percentage because of the Standard’s frequency weighting.
  • Page 30: Hd Level Metering

    Both these noise measurements are expressed in dB relative to 100% amplitude modulation of the FM carrier. HD LEVEL METERING HD Levels and Loudness This level readout for the HD1 program is typical of four such displays on this Webpage screen. The Left and Right meters are quasi-peak program audio bargraphs, with peak-hold and nu- meric display of the held value as previously explained for FM level metering.
  • Page 31: Spectrum Plots

    SPECTRUM PLOTS The 552 monitor includes an advanced, high-resolution FFT- based spectrum analyzer that delivers detailed and annotated graphic displays of selected signals. Images are under the Spec- trum Plots Webpages menu. Each signal selected for viewing car- ries its own family of graph setup options below the display. The IF Spectrum The illustration shown here is the receiver’s IF spectrum.

    Response: set to Average gives a steady and accurate level readout, Peak shows the peak value of the signal. Hold will ac- cumulate and display the highest peak value until the function is manually reset. At the bottom, the display Averages: the number of FFT compu- tations selected in the drop-down box.

    previously, LU numbers don’t equate to much standing alone. In the interest of loudness consistency between the analog-FM program and, especially, the HD1 channel, these readings are best judged against the FM audio loudness. That’s the function of the Relative to FM selection, for not only do the plots on this graph follow the loudness of the HD programs, but the ‘zero’...

    When implemented with a traditional analog oscilloscope, the XY display resembles a ‘connect-the-dots’ image of the so- named children’s activity. The 552 and most digital ‘scopes can optionally show either Lines or Points. The Points option presents a more artistic ‘constellation’ as seen in the example. In this case Points and Persistence were both engaged to also in- dicate the short-term trend of the stereo image.
