Telos Omnia.7 Quick Start Setup Manual page 4

• Note: A important word about AES reference and sample rates!
Omnia.7 offers several clock sync/reference options:
The main AES XLR inputs can accept audio with a reference of either 44.1kHz (for HD Radio) or
48kHz (for DAB). To set the sample rate, navigate to the System > System Configuration >
Sample Rate menu and set the unit's sample rate to match that of the incoming signal and the
Sync Reference control to "Main Input".
If the incoming AES audio has a different sample rate between 32kHz and 96kHz, it can be up- or
down-sampled to either 44.1 or 48kHz by setting the Sync Reference control to "Reference Input."
The unit's sample rate must be selected in the Sample Rate menu.
Finally, a dedicated external reference input is provided on the rear panel via a BNC connector
should it be necessary to sync to a clock that is not present on the incoming AES audio (such as an
HD exporter at the transmitter site). Set the Sync Reference to "Reference Input". The unit's
sample rate must be selected in the Sample Rate menu. A BNC-to-XLR cable or adapter (Pin 2
hot, Pin 3 shield) may be used for short runs without concern. For longer runs, a transformer should
be used as needed.
Front Panel Control, Menu Navigation, and Password
Unlike other products in the Omnia family, Omnia.7 uses a "joystick" type of rotary encoder for menu
navigation and control adjustment. "Rocking" the control left, right, up or down facilitates navigation
through the various menus, while turning the knob clockwise or counterclockwise adjusts individual
controls.
The factory default password is "1234". Navigate to the "Password" field then move the joystick to the
right to bring up the on-screen keyboard. When the keyboard is displayed, turning the control clockwise or
counterclockwise moves the cursor around the screen while rocking it to the right enters the highlighted
value. Once the password is entered, highlight and enter "OK". Next, highlight and enter "Unlock" to
unlock the unit.
The unit will always lock itself when the display times out and goes dark. The length of time before this
happens is adjustable in the System > System Config > Power menu.
Select the Input Audio Source
Next, navigate to the System > I/O Options > Input menu and select the proper source (analog or AES
digital) for the primary and/or backup inputs. Only the primary input is required. If a backup source is
provided, it can be used as a failover source in the event of a loss of audio on the primary input.
Configure Output Routing
Connect the audio outputs as appropriate for your installation. Omnia.7 supports balanced professional
line-level analog audio via its Left and Right Analog Outputs and AES/EBU digital output on standard XLR
connectors via the AES output. The AES outputs can also be used to provide an Omnia Direct™
(composite over AES) signal. Two composite MPX outputs are provided to feed a main/backup composite
STL or transmitter.
If you are using the Analog or AES outputs, navigate to the System > I/O Options > Main Outputs
menu, select the appropriate output source for your particular installation, and adjust the output levels as
needed.
