January, 2007

Welcome to Omnia.ONE!

I wish to offer my sincere gratitude on behalf of our company and welcome you to Omnia.ONE!

This manual was assembled by a dedicated team of specialists who were instrumental in the development
of our newest product, Omnia.ONE. This is our next step in the never-ending quest to build the best signal
processor in the world. Considerably more powerful than what its small package implies, Omnia.ONE
possesses new hardware and algorithm capabilities that even exceed its predecessors. It is also the first
audio processor to incorporate LiveWire connectivity, enabling linear audio over dedicated networks. It’s
the hottest ‘interconnect’ technology in the professional audio industry today.

Broadcasters require a lot of flexibility in an audio processor because transmission systems exist in many
different forms. The processor you choose must have the tools to meet those needs. Special firmware inside
Omnia.ONE allows it to meet the challenges of FM, AM, HD Radio, DAB, DRM, Multicasting,
Podcasting, Netcasting, Satcasting, and any other form of ‘casting’ you can think of. There’s plenty of
power inside its little 1U frame, so don’t let the size fool you!

It was 1986, in the engineering shop at Z-100, (WHTZ-FM) New York City where our first product was
born - The Vigilante FM Limiter. Twenty-one years later and with an incredibly talented team of designers
behind it, we offer you the newest baby in our ever-growing family, Omnia.ONE!

Speaking of the team, I wish to offer a sincere and heart-felt thank you to: Rob Dye, Bill Mohat, Ed

Zmuginsky, Mark Manolio, Ted Alexander, David Jablonski, Scott Stiefel, Sean Overberger, Betty Ferrell,
Steve Kiffmeyer, Denny Sanders, Marty Sacks, Mike Dosch, Kirk Harnack, Mike Uhl, Jim “Clemenza”
Armstrong, Marc Johnson, Ken Skok and a host of others (as you can see, it’s not just “Frank” anymore!).

It’s a great team of people who always maintain one goal in their minds…

Steve Church, my partner in crime and founder of Telos, first introduced DSP technology to broadcasting
in 1985. Our team of DSP gurus is the finest in the audio industry. Our own specialized DSP ingenuity has
been tremendously beneficial to Omnia’s development.

You have in your possession an incredible audio processor. Also, you have the full support of our entire
organization standing behind the product. If you have feedback, or even a new idea, we’re here to listen!
Customers, like you, offer us valuable feedback. After all, it’s feedback like yours that helped us introduce
the original Omnia.FM, and then take the industry by storm. Our quest today, just as it has been all along, is
to continue to be the audio processing brand leader.

To borrow a phrase from my old stomping grounds, Z-100 in New York City, Omnia went from worst to
first in the minds and ears of radio broadcasters. We are honored, equally humbled to say the least, and
grateful to you, our customers, for helping us make that happen! Omnia processors have been installed by
tens of thousands of broadcasters throughout the world, and I am overwhelmed when I look at the list of
our end-users. So, it’s to you, our loyal customers and friends, that I say Thank You!

To Great Sounding Audio…the World over!

keep raising the bar!

Sensus® Technology: Audio Processing

Overview

Until now, digital signal processing has been a more precise numeric implementation of well-known
analog methods. Even relatively recently designed digital audio processors couldn’t veer too far
from the comparatively simplistic concepts that analog dynamics processing had utilized… until
now!

Extremely high power DSP chips have become available and at relatively low cost, and they make it
possible to build smarter and more complex processing algorithms that were too difficult or
impossible (or too expensive) to do in the past.

Running on a platform of the latest high power DSP chips, the OmniaONE and our new Sensus®

technology takes digital dynamics processing into a completely new frontier. Instead of the two-

dimensional static processing architecture of the past, Sensus® enables the audio processor to

modify its own architecture in real time and in response to ever-changing program content.

Simply stated, Sensus® has the ability to “sense” what must be done to a signal in order to best tailor

it for the following codec. As program content changes, it “rearranges the algorithms” to accomplish

this goal. The uniqueness of the Sensus® technology makes it highly suitable not only for codec pre-

conditioning (or provisioning), but also for a range of other highly specialized signal processing

challenges. The following is a discussion of how Sensus® technology can be applied to a coded

audio environment.

Codec Provisioning

The codec is now a common denominator in the world of audio and broadcasting. Digital
broadcasting (HDTV, HD-RadioR, DAB, DRM), podcasting, webcasting, cellcasting, and
downloadable music files all employ a form of codec-based data compression in order to minimize
the bandwidth required to transmit data. The necessarily low bitrates utilized by these mediums
presents a tough challenge for any audio processor used prior to a codec.

Traditional dynamics processors were designed to fulfill the requirements of a medium where the

functions were generally static. That is, they were well suited to the rather simplistic peak control

OmniaONE Multicast - Use and Operation Manual – Version 0.90

9

and bandwidth limiting methods that were required for analog broadcasting, as well as for the signal
normalization techniques used in recording and mastering.

Audio codecs on the other hand are moving targets - each codec algorithm has its own set of
artifacts. So not only does the sonic quality vary depending on the algorithm and bitrate used, but
more importantly they vary in their ability to mask their own coding action. This is why we call it a
‘moving target’, and is why conventional audio processors fall short in a coded audio environment
and can actually make coding artifacts worse due to their inability to adapt appropriately to the
changing operation of the codec as the program content changes.

Prior art in audio dynamics processing could only address some of the challenges of provisioning

audio for coding. This hurdle existed because the codec adapts to the incoming program (so as to
generate the least amount of output data representing the input audio) causing the sonic artifacts
generated by the process to continually change. Unless the audio processor can predict these
changing characteristics of the codec, it can’t possibly create output audio that is perfectly tailored
for the coding process.

Conventional processors utilize rather simplistic high frequency limiters and fixed low pass filtering
that does not change with the program material. When these less intelligent processors feed a codec
the audio might sound acceptable one moment and offensive the next. Because they cannot “know”

what the codec will do next, the result is over-compensated, dull and lifeless audio… audio that still

contains objectionable codec-generated artifacts!

OmniaONE Multicast and HD® Radio

The advent of HD RadioR has introduced the capability to transmit multiple program streams, or
“Multicast”, within a single 96kbps digital broadcast data channel. To facilitate this, multicast relies
on the use of codecs with comparatively low bitrates. A broadcaster can choose to transmit a number
of multicast channels and select the bitrate for each one. However, the more multicast channels there
are, the lower the bitrate each channel must have in order for them to all fit within the total available
bandwidth.

In the very near future, many low bitrate multicast audio channels might exist. To achieve maximum

sound quality, the kind that attracts and holds listeners, those channels will need specialized
dynamics processing capable of creating great sound regardless of program content and bitrate.
They will need Sensus®.

OmniaONE Multicast was designed from the ground up for provisioning audio for codecs operating

at these low bitrates. With Sensus®, the innovative algorithm inside OmniaONE Multicast, it is now

possible to have consistently high audio quality with a minimum of codec-induced artifacts.
OmniaONE Multicast creates highly listenable audio lacking the dull, muffled, ‘swirley’ sound
usually associated with codecs operated at extremely low bitrates.

OmniaONE Multicast - Use and Operation Manual – Version 0.90

10

So… what’s so smart about Sensus®?

The fact is, Sensus® is smart. In real time it predicts program content that will be troublesome for

the codec, and by modifying it’s own algorithms can make appropriate changes to the program
material before it ever reaches the codec!1 The result is consistently high audio quality through a
codec-based system, even at very low (18kbps – 21kbps) bitrates.

The human voice is very difficult to code at low bitrates without quality and intelligibility suffering.

But OmniaONE Multicast with Sensus® can generate clean, smooth, crystal clear audio that’s

consistently great sounding no matter what the codec or bitrate is.

--- Important Note ---

1

It is extremely important to never directly audition the output of the OmniaONE Multicast for

audio quality without the audio being first routed through a codec!

Why?

The processed output of the OmniaONE Multicast has been ‘pre-corrected’ for the characteristics of
the following codec and because of this the audio may contain strange sounding artifacts that will
imitate the ‘inverse’ of what that codec will do. Because of this the audio exiting the OmniaONE
Multicast may be unpleasant to listen to and will certainly be inferior to that which will exit the
codec later on.

In other words, what you hear at the output of the OmniaONE Multicast will bear no relationship to

the audio quality that will be achieved after the audio has passed through the coding process!

Need a corollary to this?

It’s like trying to taste a pizza while still in the grocery store and staring at the raw ingredients that
haven’t been purchased yet.

Thank you for selecting the incredible OmniaONE Multicast Audio Processor. Your continued
patronage and support are appreciated.

Sincerely,

The Omnia Development Team

Chapter-1: Installation

Pre-Installation Tasks

Please take a few minutes to read through this chapter before proceeding with the installation. This section offers
common procedures for installing your new OmniaONE processor.

About This Manual

This manual is written to cover the OmniaONE Multicast. If you are setting up a different version of the
OmniaONE, please refer to the instruction manual for that product.

OmniaONE Components

By now, you’ve unpacked the shipping carton to gain access to this manual. Now is the time to inspect the
OmniaONE unit and its shipping carton for any signs of shipping damage. Such damage must be reported to your
carrier for any claims. The OmniaONE shipping box includes the following components:

¾ OmniaONE processor.
¾ OmniaONE Operating Manual in PDF format on Compact Disc.
¾ Warranty Registration Card. (Please complete the form and return/FAX it to Telos/Omnia)
¾ Two IEC Power Cords, one for use in the US, and one for use in Europe.
¾ One each Male and Female XLR to StudioHUB® RJ45 adaptor cables.

AC Power Environment

The OmniaONE subsystem is a DSP-based microcomputer, and therefore requires reasonably clean AC power, just
as any modern computer system does. And even though the OmniaONE 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 OmniaONE (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

Throughout this section reference is made to “software parameters.” These are part of the User Interface, which is
covered in detail in Chapter 2.

Rack Mounting

The OmniaONE 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 two­screw 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. Refer to Chapter X, “OmniaONE
User Tips”, for additional considerations on where to physically locate your processor.

AC Power Connection

OmniaONE utilizes an un-switched EMI-filtered IEC power-entry module.

OmniaONE’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, 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 OmniaONE, 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
“OmniaONE Multicast” and at about 30 seconds the Main Menu should appear. Once the Main Menu appears the
unit is ready for use.

Analog Audio Inputs and Outputs

Balanced XLR-type connectors are used as input connectors for the analog audio. Both analog and digital input
sources may be connected simultaneously, however, only the input source that has been selected is active.
Analog/Digital/Livewire Input source selection is done through the “Source” software parameter setting in the
Input/Output / Input Menu.

The stereo analog inputs Individual Left and Right
are designed for standard analog outputs are available
+4dBu balanced signals. on two male XLR jacks.

A Note About Relative Phase:

If the relative phase of your installation (including the OmniaONE) 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 submenu of the Input/Output
menu.

AES/EBU Digital Input, AES/EBU External Sync Input, and AES/EBU Output

(GREEN Male XLR)

(GREEN Female XLR)

(RED Female XLR)

The digital AES/EBU (AES-3) inputs (IN and EXT. SYNC) use industry-familiar RJ-45 connectors and utilize the
StudioHUB+ wiring standard
sample rate is necessary on the AES-3 input as a high-quality digital sample rate converter is built in. Individual
channel gain and level setting for both analog and digital domains is done using the Input Gain software parameter
settings in the Input Menu. There is one AES-3 output on a standard RJ-45 connector that provides an output at
selectable sampling rates.

Note: The analog and digital outputs are active simultaneously.

For your convenience, a pair of XLR adaptor cables are supplied with the unit. The male XLR lead with the
GREEN shrink tubing is used for AES OUT. The male XLR lead with the RED shrink tubing is not used.
The female XLR lead with the GREEN shrink tubing is used for AES IN and the female XLR lead with the RED
shrink tubing is used for AES EXTERNAL SYNC IN.

Ethernet Connection

The RJ-45 10BaseT / 100BaseT Ethernet / Livewire I/O jack can be used simultaneously for both TCP/IP based
remote control of your OmniaONE and audio input/output to your existing Livewire network.

Please note that the Livewire 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

RS-232 Modem Connection (DB-9M)

This DB9-male connector can be used to connect an external dialup modem for a bi-directional computer remote
control connection.

NOTE: This connector is for a remote control external modem connection only. Please see Appendix B for
information on how to use a terminal program along with an internal RS-232 connector for troubleshooting
purposes.

RS-232 Modem Port

NOTE: You must use a standard straight-through serial cable and not a null modem cable when connecting the RS­232 connector of the Omnia and the external modem. Typically this would be 9-pin to 25-pin cable. (External

modems traditionally have 25 pin connectors in "DCE" configuration. The OmniaONE has a 9 pin in "DTE"
configuration, so the standard 9-pin to 25-pin cable will work).

General Purpose Interface (GPI) (DB-9F)

This DB9-female connector serves as a four-input, optoisolated 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 OmniaONE’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 OmniaONE Remote Control application. Full details,
including connector pinout, are covered in

*Please note that the Trigger Script 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:

Powering Up

Now you are ready to power up the OmniaONE 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 OmniaONE is first powered on, audio will appear at the analog audio outputs in approximately ten
seconds. The AES/EBU outputs also become usable at this time however full initialization of the AES/EBU 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 Main Menu will appear:
