President’s Note: Welcome to Omnia.11!
Cleveland, Ohio
September, 2010
If you love Rock-and-Roll there's a good chance you'll understand the following scenario.
Consider how daunting it must have been for the Beatles to follow-up "Sgt. Pepper," or what the
next concept was in Pete Townshend's mind after the worldwide acclaim of "Tommy."
Personally, I always wonder how Bruce Springsteen contemplates his next project after the
completion of many of his masterpieces.
Well processing gang, seems I now understand the predicament! Your overwhelming acceptance
of Omnia processors parallels the above scenarios for all of those artists. OK, so maybe there
won't be a "processing rock opera", but the popularity of Omnia, as made by you, has put it in
rock-star status among broadcastings elite! Humbly....I wish to thank each and every one of you
for your dedication and support.
Now, Omnia embarks upon the next phase - or tour - of this wonderful journey. You know, Mr.
Springsteen said it perfectly, "One day, we'll look back on this, and it will all seem funny." He’s
right, as I look back on all this, it's been - and remains - an amazing ride!
Now it's time for us to offer you our follow-up as we present Omnia.11. A lot of anticipation
awaits Omnia.11, and our goal was to climb the charts again, with a bullet. By now you're heard
or read all of the stuff from the marketing gang. So I'll spare those details. But it is important to
note that aside from the effort undertaken to create Omnia.11, there's a tremendous team who
deserve recognition for this product. As said in other communiqués, Omnia isn't just "Frank"
anymore. Now you get to hear and see the results of that statement. Omnia.11 resides on a whole
new firmware platform, which incorporates both DSP and an industrial grade quad-core PC. I
believe this is a first in the processing realm. In order to do this, the Omnia team worked
extremely hard to assemble a platform that is powerful, flexible, and ready for the future. It's my
view that our platform design and firmware selection will create possibilities the 'other' guys are
still dreaming about. So in addition to a great sounding processor, you also possess a device that
is designed for the ever changing technical landscape we find in broadcasting today.
To that extent, Rob Dye, Bill Mohat, Ed Zmuginsky, Corny Gould, and Mark Manolio are to
thank for their creativity. Additionally, there are quite a number of end-users who shared their
ideas with us, and we're extremely grateful for the input from everyone.
I've always felt that competitive quality sound is what ultimately sells a processor, not the
number of bands or the latest whimsical features we see offered by others. In Malcom Gladwell's
book "Outliers," he details numerous stories about how various people reached their level of
success. The short form answer is that it takes close to 10,000 hours of work or practice to reach
this lofty goal. Pretty insightful stuff! I have no doubt that my algorithmic running mates Rob
Dye and Cornelius Gould have long surpassed this milestone. Their efforts, input and insight to
the algorithms in Omnia.11 are worth a book unto themselves. Ask Corny about the multitude of
hours we spent in our development lab going over algorithm performance and breaking down the
barriers to achieve increased performance in what is today Omnia.11.
i
Hopefully by now you can draw your own conclusion as to which company has not only become
the world's leading broadcast processing developer, but also whom all others look to clone. We
chuckle when our tech concepts show up in product descriptions of other companies.
In closing, I want to Thank You, once again for your support in us. As you get rolling with
Omnia.11, please know we are there 24/7 should you need assistance. As always, we'd love to
know your feedback, so please feel free to share. As a friend in the live steam hobby told me
about his business, "If you like the product, tell others. If you don't, then tell me."
Rock on!

Omnia.11 Quick-Start Setup Guide
We know that you’re probably in a hurry to begin using your new Omnia.11. If you have technical expertise and previous
knowledge of audio processor fundamentals, using our 2-page Quick-Start Setup Guide below will get you up and running
as quickly as possible.
Please refer to the illustrations and user interface overview below to become familiar with the location of the various
controls and connectors associated with the installation, and then follow the steps on the next page to proceed with the
installation.
Headphone Jack Headphone Level Control Jog Wheel
Icon Buttons Tabs
Touch Screen LCD Display Metering Area Menu Area
Sub-Group Buttons
Front Panel User Interface Overview:
Touch the Icon buttons near the top of the screen to select the section of the processor to view and adjust.
At the top of both the Metering Area and the Menu Area are tabs that organize the meters and controls into smaller
groups. Touch the tab for the desired group to bring up the meters and controls for that group.
Additionally, any sub-groups of controls in a tab (if any) are indicated by small buttons on the left side of the Menu
Area. Touch the desired button to bring up the controls in that sub-group.
To select a variable control in the Menu Area for adjustment, touch it to select it (it will be highlighted in an
alternate color when selected) then rotate the Jog Wheel to adjust it in real time. No additional confirmation touch is
needed. Note: The Jog Wheel’s push switch is not yet implemented.
The state of On/Off controls can be changed either by rotating the Jog Wheel (counter-clockwise for off and
clockwise for on) or by touching the left or right half of the control as appropriate. Touching the left half of the
control will turn it off and touching the right half of the control will turn it on.
Drop-Down controls (controls that have more than 2 selections in a drop-down list) are changed by first touching the
control to display the list and then touching the desired selection from the list.

1. The Omnia.11 is a large unit so it would be advisable to have the help of an assistant when installing it in the rack. Pull
outward on the outside of each handle until you hear a click and they both securely lock into place. Using the handles,
install the Omnia.11 in the equipment rack using all four rack screws. Once secured to the rack, slide the release pin
(located on the back of each handle at the top) toward you and fold the rack handles back to their normal position.
2. Connect AC power to the unit (there is no power switch!)
3. Connect the audio inputs that are appropriate for your installation. The Omnia.11 accepts balanced professional linelevel analog audio or AES/EBU digital audio on standard XLR connectors. If you have an existing Livewire system,
the single Livewire Ethernet connection is all that is needed for audio I/O (except for the composite MPX outputs).
4. Touch the “Input” icon button near the top-left of the screen to bring up the Input menu and metering.
If the “Basic” tab is not selected, touch it to select it. From the “Input Source” drop-down, select the Analog,
AES/EBU or Livewire input as appropriate for your installation. If your audio source is providing an audio feed you
should then see meter activity on the bargraph meters.
5. While driving the inputs with typical program material at normal operating level, adjust the appropriate “Master”
Input Gain control until the peak-reading input bargraph meters are peaking up to at least –15 and up to –12 dBFS or a
little higher. If the left/right audio levels coming into the Omnia.11 are somewhat unbalanced, you can adjust the
“Right Trim” control to adjust the level of the right channel alone over a limited range.
6. Connect the outputs that are appropriate for your installation.
7. Touch the “Output” icon button at the top-right of the screen to bring up the Output menu and metering. If the
“Basic” tab is not selected, touch it to select it. Touch the “FM Options” button on the left side of the Menu Area and
ensure that the Pre-Emphasis, De-emphasis and BS-412 settings are correct for your system and your location. The
de-emphasis only affects the XLR outputs. The composite MPX outputs are never de-emphasized. All outputs are
active simultaneously.
8. Now touch the appropriate button above the “FM Options” button to select the group of output controls you will be
using. Adjust the appropriate control so that the output level is correct for the equipment that follows the Omnia.11.
For access to the composite MPX stereo generator controls, touch the “Composite” button.
9. Touch the “FM” icon button then touch the “Preset” tab to display the list of factory processing presets. Touch the
preset you would like to start with to select and activate it. Note: The same processing “Preset” tab is also available in
the Wide Band, AGC or Limiters menus as well as the FM menu.
We strongly suggest listening to all the factory presets, regardless of their name, to get a feel for their differences. For
each one, be sure to adjust the clipper “Drive” control here in the “FM” menu as low as possible for the loudness
needed. This controls the primary loudness vs. distortion tradeoff.
The Omnia.11 Quick-Start Setup is now complete. Please read the rest of the User Manual to learn about some of
the features that make the Omnia.11 unique, for additional details on proper installation and for full details on the
operation and adjustment of every control function.

Chapter-1: Installation
Pre-Installation Tasks
Please take a few minutes to read through this chapter before proceeding with the installation of your new Omnia.11
processor.
About This Manual
The latest version of this manual is always available for download from the Omnia website here:
http://omniaaudio.com/manuals
Omnia.11 Components
By now, you’ve unpacked the shipping carton to gain access to this manual. Now is the time to inspect the Omnia.11
unit and its shipping carton for any signs of shipping damage. Such damage must be reported to your carrier for any
claims. The Omnia.11 shipping box includes the following components:
¾ Omnia.11 processor.
¾ Omnia.11 Operating Manual.
¾ Warranty Registration Card. (Please complete the form and return/FAX it to Telos/Omnia)
¾ Two IEC Power Cords, one of the USA/Canada style, and one of the Euro style.
AC Power Environment
The Omnia.11 subsystem is a DSP-based microcomputer, and therefore requires reasonably clean AC power, just as
any modern computer system does. And even though the Omnia.11 power supply is equipped with robust AC
transient suppression, we recommend that an “online” style (non-switching type) Uninterruptible Power Supply
(UPS) with transient surge suppression be employed.
At transmitter sites there can be heavy transients on the power lines as well as significant surges introduced into the
power system by frequent lighting strikes. These are unwelcome power line events and can damage even the most
robust equipment. Therefore you should give the AC power environment and installation practices thorough
consideration before plugging in the Omnia.11 (or any other microcomputer-based equipment).
A White Paper by one of our Support Engineers can be found on the Telos Systems website at the URL listed below.
It details proper grounding and contains links to some surge suppression products for both the power mains and the
often-neglected telephone, Ethernet and ISDN line connections that can (and do) conduct powerful surges into the
equipment.

Installation & Connections
Rack Mounting & Grounding
The Omnia.11 is a large unit so it would be advisable to have the help of an assistant when installing it in the rack.
The Omnia.11 requires four RU (7" [17.78
until they lock securely. Then and only then rack mount the unit using all four rack screws! No other two-screw
mounting arrangement will secure the unit properly or prevent distortion of the front panel!
Once secured to the rack, slide the release pin for each rack handle toward you and fold the rack handles back to
their normal position
Adequate ventilation should be provided, and although not required, 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.11’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
cm]) of rack space. Pull the outer edge the 2 rack handles towards you
Omnia.11 utilizes an un-switched EMI-filtered IEC
power-entry module.
AC Power Connection
Omnia.11’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.

Rear Panel Connections
Analog Audio Inputs and Outputs
Balanced XLR-type connectors are provided in the lower left section of the rear panel for the analog audio. Both
analog and digital input sources may be connected simultaneously, however, only the input source that has been
selected in the menu will be active. Analog/Digital/Livewire input source selection is done through the “Input Src”
(Input Source) software parameter setting in the Input menu.
All outputs are active simultaneously.
The stereo analog inputs Individual Left and Right
are designed for standard analog outputs are available
+4dBu balanced signals. on two male XLR jacks.
Pin 2 is Hot. Pin 2 is Hot.
A Note about Relative Phase:
If the relative phase of your installation (including the Omnia.11) differs from that of your existing system, your
announcers may feel that they sound “weird” in their headphones. If this occurs, then the relative phase of the
processor is 180 degrees from what your air talent is used to. To remedy this, you can either reverse the polarity of
both of the analog inputs or simply change the “Invert” setting to [Both] in the Input menu.
3
Stereo Generator Connections
Four standard female BNC connectors comprise the Omnia.11’s stereo generator connections.
There are two composite MPX outputs with independent software level controls, one SCA input with level adjust
trimpot and one 19 kHz pilot sync output.
COMP 1 & COMP 2 (Composite Outputs 1 & 2) (BNC)
These two low impedance outputs (Composite 1 and Composite 2) are each capable of driving up to 100 feet of
RG-58A/U coax cable. The output levels are individually adjustable so the unit can operate as a “composite
DA” to drive a variety of equipment. The output levels and other stereo generator settings are set through
software parameters in the Stereo Generator submenu of the Input/Output menu. An internal jumper sets the
output impedance to either 5 ohms (the factory setting) or 75 ohms. The default setting is appropriate for the
vast majority of exciter connections. However, in the event that a higher source impedance is required, a jumper
can be moved (one for each composite output) on the motherboard to change the source impedance to 75 ohms.
For reference, JP10 is for Composite #1, and JP9 is for Composite #2.
19 kHz OUT (Pilot Sync Output) (BNC)
This TTL-level 19 kHz square wave output can be used as the reference signal for most RDS or SCA generators
that operate at 57 kHz or other multiple of the 19 kHz pilot frequency. This Sync output is phase and frequency
locked to the stereo pilot. When this signal is used to synchronize an external SCA or RDS generator, this
locking assures that no difference frequencies exist which may cause intermodulation components between the
pilot and the SCA signal.
SCA INPUT (BNC)
Any SCA or RDS signal above 53 kHz can be added to the composite outputs of the Omnia.11 by connecting
the signal to the SCA INPUT connector. The SCA signal is mixed in the analog domain directly into both
composite outputs. A high-pass filter on the SCA input provides SCA to main-channel crosstalk protection. The
SCA injection level can be adjusted using the SCA IN LVL control trimpot. See below for details.
SCA IN LVL (SCA Input Level) (trimpot adjustment)
Located just above the SCA Input BNC jack is the SCA IN LVL (SCA Input Level) adjustment control.
Carefully insert a small bladed screwdriver into the hole and adjust the control if needed to set the SCA
injection level.
4
AES/EBU Digital Input, Outputs & AES/EBU External Sync Input
The digital AES/EBU (AES-3) inputs (AES INPUT and AES SYNC IN) use standard balanced 3-pin female XLR
connectors. They accept any sampling rate between 32kHz and 96kHz. No user adjustment of the sample rate is
necessary on the AES-3 input as a high-quality digital sample rate converter is built in.
There are two AES-3 outputs on standard balanced 3-pin male XLR connectors. These provide either an internally
generated output sample rate of 48 kHz or the sample rate can be locked to an external AES/EBU signal applied to
the AES SYNC IN connector or to the AES/EBU input signal. These options are selectable using the “Samp. Rate”
(Sample Rate) setting in the Output menu.
Note: The analog and digital outputs are active simultaneously.

The setup and operation of the Omnia’s Remote
Control capability is covered in detail in
Appendix C, starting on Page
*Please note that the RS-232 functionality is not
yet implemented in the current software but will
be available with a free downloadable software
update. Please check the Omnia website for new
software announcements, download links and
manual updates at: http://www.omniaaudio.com/
General Purpose Interface (GPI) (DB-15F)*
NOTE: GPI functionality is not available with the initial software. It will be made available
to you in a future software update.
This DB15-female connector serves as a four-input, opto-isolated interface to the Omnia's internal Trigger Script
functions*. Four of the pins are “trigger” inputs, one is a bias voltage input, one is a +5V power output, and the
remaining three are “ground.” The trigger inputs can be used to dynamically alter the Omnia.11’s operation in
response to logic transitions on the interface connection. Virtually any parameter of the Omnia can be controlled
using the Trigger Scripts.
The Trigger Script Interface is a standard component of the Omnia.11 Remote Control Interface. Full details,
including connector pinout, are covered in Appendix C, starting on Page
*Please note that the GPI and Trigger Script functionality are not yet implemented in the current software but will be
available with a free downloadable software update. Please check the Omnia website for new software
announcements, download links and manual updates at: http://www.omniaaudio.com/

Powering Up
Now you are ready to power up the Omnia.11 for the first time.
Connect AC power to the unit using the appropriate supplied power cable for your location.
(There is no power switch!)
When the Omnia.11 is first powered on, audio will appear at the analog audio outputs in approximately 1 minute.
The AES/EBU and Livewire outputs also become usable at this time however full initialization of the digital ports is
not complete for several more seconds and a small audio glitch may be heard when the final sample rate converter
initialization is complete. Once the boot process is finished the following screen will appear:
“Input” Screen
You will note that the screen defaults to the adjustment (ADJ) mode with the Input menu and metering displayed.
The Omnia.11 is now ready for configuration and use.
Please proceed to the next chapter to learn how to use the touch screen graphical user interface and how to configure
the Omnia.11 for your system.
