Physical Installation And Initial Configuration; Input Configuration - Omnia .9 Installation & User Manual

QUICK STARTUP GUIDE

Physical Installation and Initial Configuration

Connect AC power to both of the internal power supplies. There is no power switch. When only one power supply is connected,
the unit sees this as a failure in one of the supplies and an audible alarm will result. You can silence this alarm by pressing the
small red button between the power supplies.
Redundant power supplies help protect you in the unlikely event that one fails. However, it is far more likely that the unit will
lose power because of an interruption in the AC mains circuit feeding the unit. Best engineering practice recommends that each
supply be fed from a different power source for maximum redundancy.

Input Configuration

Connect the audio inputs as appropriate for your installation. Omnia.9 accepts balanced professional line-level analog
audio via its Left and Right Inputs in the Main Analog I/O section of the rear panel, AES/EBU digital audio on standard XLR
connectors via its Main and AES Reference Inputs in the Main Digital I/O section of the rear panel, Aux Digital Input in the
Aux Digital I/O section, and Livewire+ AES67 inputs / Outputs over IP. (AoIP is standard on new Omnia 9's as of April, 2018.
Network setup is required). Legacy users seeking AoIP IO should contact their dealers or Telos Customer Support and ask for
the MKII upgrade).
A Word about AES Reference and Sample Rates:
If you need to sync the Omnia.9 to an external reference, use the AES Reference Input to ensure that the
externally generated AES clock will be used as the main clock for the Omnia.9.
Note:
Omnia.9's main sample rate MUST be set to match the rate of the external reference at either 44.1 or 48kHz.
These settings are found in the System Configuration portion of the System menu. For HD Radio, a sample
rate of 44.1kHz is required. For DAB radio, a sample rate of 48kHz is required.
Sample rate converters are present on both the Main Digital In and Aux Digital In connections, and accept any AES signal from
32 – 96kHz.
From the Omnia.9 Home screen, select System, then I/O Options, then Input 1, 2 or 3. Each of Omnia.9's three configurable
internal inputs can be fed from any of the physical rear-panel inputs or with Livewire, by using the drop-down menus for each
Input Source as appropriate for your installation.
In turn, each processing core is fed from one of the three internal input sources. The FM, HD-1, and Stream 1 cores are fed from
Input 1. HD-2 and Stream 2 are fed from Input 2, while HD-3 and Stream 3 are fed from Input 3. The (low-delay) Studio core
is fed from Input 1 by default but can be assigned its own separate input.
