    Through Radio digital audio sampling rate of 44.1kHz. For reasons stated in the Quick-Start Setup section, the pre- ferred connection for the JUSTIN 808 is in the HD1 digital audio feed to the HD exciter or exporter. Interconnection for this mode is diagrammed on Page 12.

    CONSIDERATIONS Two basic installation modes are available to you. The pre- Preferred ferred mode places the JUSTIN 808 in the HD1 airchain. In this Installation mode, slightly more ‘diversity delay’ is purposely programmed in the into the FM audio path, and the JUSTIN 808 then provides vari-...

    808 is entered on the Network submenu. Switch Mode: from DHCP to Static IP and type-in the requisite information. It will be necessary to specify a port for the JUSTIN 808 on the Port Forwarding network router. Within the router’s Port Forwarding utility you are able to enter your static IP address for the unit (Internal IP), followed by a colon and a port number.

    IP address if it were not for IP-forwarding providers available on the Internet. Their services, which are either free or at a very modest charge, will allow the JUSTIN 808 to keep the pro- vider apprised of its reassigned IP address each time that ad- dress is updated by the ISP.

    FRONT PANEL APPOINTMENTS All setup and operating adjustments of the JUSTIN 808 are un- der firmware control. There are no jumpers, switches or me- chanical potentiometers, only the front-panel ‘jog’ knob, A; the Back button, B; and the OLED display, C identified in the illus- tration below.

  • Page 21: Delay Error Correction

    Diversity delay may be set with some degree of accuracy by lis- tening to both the FM and the HD1 programs in the ‘split mode’ offered by many HD Radio receivers, including the JUSTIN 808. The human ear/brain interface is sensitive to a time and a phase difference between audio sources, and the proper delay was historically dialed-in by this method.

    JUSTIN 808 slowly correcting the error at the default rate of 50 samples per second. Implications of faster correc- tion rates were mentioned in the Quick-Start Setup section, and are discussed in greater detail later. Additional options and information are available on the FM/HD Measurements menu shown below.

    An ‘Event’ is not necessarily an alarm condition. Rather, the Events term refers to changes in operation of the JUSTIN 808. For ex- ample, when the JUSTIN 808 loses and finds correlation, this will be noted. Also when the unit is tuned to a different fre- quency, regains AC mains power, or whenever the Ballgame Mode is selected, and by what means.

Alignment Out of Range These alarms are indicated on the front panel of the JUSTIN 808, either as individual LED indicators, or they are flashed on the OLED display.
  • Page 30 This alarm monitors the AES digital audio that is looped- AES Audio Loss through the JUSTIN 808. Setup of this alarm is identical to the other two audio-loss alarms. Loss of the looped-through audio will always result in one of the other audio loss alarms being triggered, as the looped audio is being delayed and transmitted, either as the HD1 program or the FM channel.
