Installation & Connections
Rack Mounting & Grounding
The Omnia.ONE requires one RU (1.75" [44.45 mm]) of rack space. Rack mount the unit using four rack screws. If
only two screws are going to be used, they should be in the bottom holes in the Omnia front panel. No other two-
screw mounting arrangement will prevent distortion of the front panel!
Adequate ventilation should be provided, and it is always good engineering practice to allow one blank rack space
immediately above and below the Omnia, especially if equipment generating significant heat is located below the
unit. You may install 1RU (1.75") vented or solid rack panels to fill these spaces.
The processor should be installed into a properly grounded 19" equipment rack.
It is a good idea, especially at transmitter sites, to run a separate ground strap or braid from the Omnia.ONE’s
chassis to a solid rack or station ground point. Although no separate ground lug is provided, the end of the strap or
braid can be clamped under the Omnia’s top cover using the Omnia’s existing top cover screws.
AC Mains Power
AC Power Connection
Omnia.ONE utilizes an un-switched EMI-filtered IEC power-entry module.
Omnia.ONE’s automatic voltage–sensing, high-efficiency switching power supply allows it to operate on AC mains
voltages from 100 to 240 VAC and from source frequencies of either 50 or 60 Hz.
In the USA or Canada, plug the provided IEC type AC power cord into the unit and then into a grounded AC outlet.
Outside of the USA you must use the appropriate power cord that complies with local electrical regulations.
After power is first applied to the Omnia.ONE, the LCD screen, the “in” and “out” LED’s and the rightmost
segments of the LED bargraph meters should light.
After about 20 seconds the LCD screen should show “Omnia.ONE” and at about 30 seconds the Main Menu should
appear. Once the Main Menu appears the unit is ready for use.
