Welcome to Omnia.ONE!

What’s New?

New in soft wa re version 2.6 (for the FM style only) is an optional fifth li miter band! The High Band AGC o utput on the FM style now feeds an optional 6.5kHz crossover and a Super-High Band limiter. There is also some new Livewire-based GPIO functionality.

Also new is the SG style. The SG is a stand-alone FM stereo generator (no processing). It is equipped with a built-in composite clipper and features a single-sideband option.

President’s Message:

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

This is our next step in the never-endin g q uest to build the best signal pro c e ssor 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, FMing, 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 engine ering sho p 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-gro wi ng fa mil y, Omnia.ONE!

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

Ed Zmuginsky, Mark Manolio, Ted Alexander, David Jablonski,, Betty Ferrell, Marty Greenberg, Steve Kiffmeyer, Denny Sanders, Marty Sacks, Mike Dosch, Kirk Harnack, Mike Uhl, Jim “Clemenza” Armstrong, Marc Johnson, Milos Nemcik, 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…keep raising the ba r!

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 special ized DSP ingenuity has been tremendously beneficial to Omn ia ’ 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 indus try 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 Cit y, Omnia went from worst to f i rst 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!

Frank Foti,

President, Omnia Audio

Omnia.ONE FM Quick-Start Setup

We know that you’re probably in a h urry to begi n using your new Omnia.ONE FM. If you have tec hnical expertise and previous knowledge of audio processor fundamentals, using this Quick-Start guide will get you up and running as quickly as possible. P le a se refer to the full User Manual for additional installation and setup information.

The following illustrations sh ow the location of the various controls and connectors associated with the installation:

Headphone Jack Headphone Level Control Jog Wheel

Main Menu / G/R Metering LCD Display Level Meters

1. Install the Omnia.ONE in the equipment rack using at least two rack screws. If only two screws are used, they MUST

be installed in the bottom holes of the rack ears!

2. Connect the audio inputs that are appropriate for your installation. The Omnia.ONE accepts balanced line-level analog

audio via the XLR connectors, AES/EBU digital via the bottom RJ-45 jack (using the “StudioHub” standard pinout) or Livewire.

NOTE: Livewire audio I/ O is only to be used if you have an existing Axia or other Livewire syste m. O therwise, the Livewire Ethernet jack can be used to remote control the Omnia.ONE via its built-in webpage interface. See Appendix C in the full User Manual for details.

3. Connect the audio outputs in a manner that is appropriate for your installation. We suggest usi ng the composite MPX

BNC output s (and there fore the O mni a’s built-in MPX stereo generator) if at all possible for best performance.

4. Connect AC power to the unit (there is no po wer switch!)

5. Navigate to the Input/Output / M e te r Select setting and select Input.

6. Navigate to the Input/Output / I np ut / Inp ut Src setting and select the Analog, AES/EBU or Livewire input as

appropriate for your installation. If your audio source is active, you should now see meter activity on the LED bargraph meters.

7. While driving the inputs with typic al program material at normal operating level , navigate back up to t he Input/Output

/ Input menu (by highlighting and clicking on the “<-EXIT” option) and adjust the appropriate input Level control until the peak-reading input bargraph meters are peaking up to at least –15 and up to –12 dBFS or a little higher.

8. Navigate to the Input/Output / Out put / FM Opt i ons submen u and ensure that the Pre-Emphasis, De-emphasis and

BS-412 settings are correct for your system and your location. If you will not be us ing the O mni a’s built-in stereo generator, it is very important to ensure that the Omnia i s the only device providing the FM pre-emphasis (PreEmphasis ON and De-Emphasis OFF) and that any link be tween the Omnia’s output and the input to the FM exciter is fully linear with no codecs. If this is not possible, the Omnia must be lo c a te d at the transmitter site, driving the FM exciter directly.

9. If yo u are using the Omnia’s built-i n s t ereo generator, navigate to the Input/Output / Stereo Generator menu and adjust

the appropriate composite output level control (Comp #1 or Comp #2) for 100% modulation on your station’s modulation monitor. Similarl y, a djust the Pilot Lvl control so that the 19kHz stereo pilot injection level indicates between 8 and 10 percent as shown on your station’s stereo modulation monitor. If your modulation monitor does not show pilot injection but you are c e r ta in that the total modulation is correct at 100%, simply set the Pilot Lvl control to

9.0%.

If you are using the AES/EBU output to feed pre-emphasized audio to your linear STL or digital exciter, navigate instead to the Input/Out put / Output menu and adjust the appropriate output level control for the equipment that follows the Omnia.ONE. Ensure that any limiters, clippers and/o r pre-emphasis in the exciter/transmitter are defeated.

10. Navigate back to the Main Menu, highlight Preset: and clic k. Rotate the jog wheel to display the preset you would

like to start with and click to select it. G o through all of the presets and start wit h one that sounds best to you.

11. We suggest that each time you try a new factory preset, you adjust the Clip Drive in the Proce s s ing / Adjust

Processing / Clipper menu as follows: Starting with the default setting for a preset, adjust it down in 0.5 dB steps until the loudness just drops below the d esired level and then bring it up slightly from there. This should be the optimum setting for your statio n and market. With most presets, there should be roo m to turn it up a bit as well if a bit more loudness is needed. Turn it up just enough to achieve the desired lo udness level. If you have t o turn it up too much, to the point where distortion becomes obtrusive, it would probably be best to start with a more aggressive preset.

The Omnia.ONE Quick-Start Setup is now complete. For more detailed installation and oper a ting instructions (including details about every control functio n) a nd to learn about some of the features that make the Omnia.ONE unique, please refer to the latest version of the full Omnia.ONE user manual available on the Omnia website here:

Omnia.ONE.SG Quick-Start Setup

We know that you’re probably in a h urry to begi n using your new Omnia.ONE.SG. If you have technical expertise and previous knowledge o f stereo generator fundamentals, using thi s guide will get you up and running a s quickly as possible. Please refer to the full User Manual for a dditional installation and setup information.

The following illustrations sh ow the location of the various controls and connectors associated with the installation:

Headphone Jack Headphone Level Control Jog Wheel

Main Menu / G/R Metering LCD Display Level Meters

1. Installation: Install the Omnia.ONE.SG in the equipment rack using at least two rack screws. If only two screws are

used, they MUST be installed in the bottom holes of the rack ears!

2. Connect the audio inputs that are appropriate for your installation. These should originate from an external FM

audio processor and ideally should be pre-emphasized and fully band limited to 16kHz.

3. Connect the Omnia’s composite MPX BNC output(s) as appropriate for your installation to your FM exciter’s

baseband composite MPX input or composite STL transmitter.

4. Connect AC power to the unit (there is no power switch!)

5. Navigate to the Discrete I/O / Meter Select setting and select Input.

6. Navigate to the Discrete I/O / Input / Input Src setting and select the Analog, AES/EBU or Livewire input as

appropriate for your installation. If your audio source is active, you should now see meter activity on the LED bargraph meters.

Input Calibration: The Omnia ONE.SG is designed to accept pre-processed audio from an external FM audio processor.

Ideally, this audio should be pre-emphasized and sourced only through a lossless link using Livewire or AES/EBU. Analog L/R XLR input can also be accepted. Since the Omnia ONE.SG includes a composite clipper, it is very important to calibrate the input level p roperly so that when the Composite Clip Drive control is set to 0.0, no composite clipping is taking pla ce.

7. Using typical pro gram material, turn up the main clipper drive on your external FM processor temporarily to provide

a more steady “worst-case” level at the input of the Omnia ONE.S G. If using a digital out put on the external FM processor, s et its peak output level to -12.0dBFS if possible. If so, set the Omnia’s input Level control in the Discrete I/O / Input menu to 0.0dB to start.

NOTE: The Omnia ONE SG’s input meters are specially calibrated with higher resolution above -12dBFS for easy and

precise input level calibration. T he first yellow LED comes on at -12.1dBFS, the second at -11.9dBFS and subsequent ones every 0.2dB above that. The composite clip point (with 0.0dB drive setting) is -12.0dBFS.

8. In the Discrete I/O / Input submenu, adjust the appropriate input Level control until the peak-reading input bargrap h

meters are just lighti ng only the first one or two yellow LEDs. If there i s some overshoot in the output of your external FM processor or the link between it and the Omnia ONE.SG, more than the first LED may light. This should be OK as long as there is not more than a dB or so of overshoot. If there is more overshoot than that, you may need to lower the input level a bit. Be sure in any case that the red “0”dBFS LED’s never light.

9. Ideally, the de-emphasis in the output of your external FM processor should be defeated so that the Omnia ONE.SG

is receiving a pre-emphasized, 16kHz band-limited signal. If not, you can turn pre-emphasis and low-pass filte ring on. Navigate to the Stereo Generator / Adjust SG submenu and ensur e that the Emph Std (50us or 75us), Pre- Emph (OFF or ON) and Input LPF (OFF or ON) settings are correct for your system and your location.

10. Here in the Stereo Generator / Adjust SG submenu, navigate down to the Comp #1 or Comp #2 controls and adjust

the appropriate one for 100% modulation on your station’s modulation monitor. Similarly, adjust the Pilot Lvl control so that the 19kHz stereo pilot injection level indicates between 8 and 10 percent as shown on your station’s stereo modulation monitor. If your modulation monitor does not show pilot injection but you are cer ta in that the total modulation is correct at 100%, simply set the Pilot Lvl control to 9.0%.

11. To save your settings as an SG Config preset, navigate to the Save SG Config setting in the Stereo Generator menu,

click on “Name”, enter a preset name using the jog wheel, turn the jog wheel one more click clockwise and click on “Save”. Similarly, I/O configuration presets can also be saved from the Discrete I/O menu.

12. Remember to return your external FM processor’s main clipp e r drive control to its previous level.

NOTE: To engage the special single-sideband mode available in the Omnia ONE .SG, navigate to the Stereo Generator / Adjust SG submenu and set the SB Mode control to “SSB”. No other adjustments should be needed.

The Omnia.ONE Quick-Start Setup is now complete.

3. Connect the audio outputs in a manner that is appropriate for your installatio n. N ormally this will be mono balance d

analog output to your AM transmitter using either the LEFT or RIGH T output XLR. If you ha ve 2 transmitters, you can use one output for each transmitter and thus have separate level adjustments for each.

4. Connect AC power to the unit (there is no power switch!)

5. Navigate to the Input/Output / M e te r Select setting and select Input.

6. Navigate to the Input/Output / Input / Input Src setting and select the Analog, AES/EBU or Livewire input as

appropriate for your installation. If your audio source is active, you should now see meter activity on the LED bargraph meters.

7. If you will be running in mono, navigate to the Input/Output / Input / Mono Mode and select the desired mode. Mono

L will feed the left channel inp ut’s a udio to both output channels, M ono R the s ame for the right channel input. Mono L+R will sum the left & right inputs and feed the sum to both outputs.

8. While driving the input with typical program material at normal operating level, navigate to the Input/Output / Input

menu and adjust the appropriate input Level control until the p e a k-reading input bargraph meters are peaking up to at least –15 and up to –12 dBFS or a little higher.

viii

9. Navigate to the Input/Output / Output / AM Options submenu and ensur e that the Output Polarities, LPF

Frequency, Asy m Mod and Tilt (normally only used for older plate-modulated transmitters) adjustments are correct for your system and your locatio n. If you will be using asymmetrical modulation to increase your positive mo dulation above 100%, ensure that when the Asym Mod control is t urned up, only the positive modulation peaks are increasing, not the negative peaks. If you find the opposite is true, select Invert for the appropriate output in the menu above.

NOTE: To help make setting modulation levels and positi ve peaks easier, temporarily set t he Processing / Adjust

Processing / Clipper / Clip Drive control to a high s etting (such as 3.0dB).

10. Navigate to the Input/Output / Outp ut menu and adjust the approp r ia te c ontrol so that the output level is correct for the

equipment that follows the Omnia.ON E . Typically this will be the modulation level of your AM transmitter. Ensure that the negative peaks never hit full-cutoff (100%) and then, if desired, increase the asym mod control until positive peak modulation is between 120-125%.

11. Remember to return the Clip Drive control to its previous l e vel.

12. Navigate back to the Main Menu, highlight Preset: and click. Rotate the jog wheel to display the preset you would

like to start with and click to select it. G o through all of the presets and start wit h one that sounds best to you.

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 Omnia.ONE processor.

About This Manual

This manual is now written to cover all 4 styles of the Omnia.ONE. This chapter will cover only general installation topics. Topics unique to a specific style are covered in style-specific sections within Chapters 3 and 4. The latest version of this manual is always available for download from the Omnia website here:

http://www.omniaaudio.com/support/manuals.htm

Omnia.ONE Components

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

 Omnia.ONE processor.  Omnia.ONE Operating Manual.  Warranty Registration Card. (Please complete the form and return/FAX it to Telos/Omnia)  Two IEC Power Cords, one of the USA/Canada style, and one of t he Euro style.  One each Male and Female XLR to StudioHUB RJ45 adaptor cables.

AC Power Environment

The Omnia.ONE subsystem is a DSP-based microcomputer, and therefore requires reasonably clean AC power, just as any modern computer system does. And even though t he Omnia.ONE power supply is equipped with robust AC transient suppression, we recom mend that an “online” style (non-switc hing type) Uninterruptible P ower Supply (UPS) with tr ansient surge suppr ession be e mpl oyed.

At transmitter sites there can be heavy transients on the power lines as well as significant surges introduced into the power system by freque nt lightin g s t rikes. These are unwelcome power line events and can damage even the most robust equipment. Therefore you should give the AC power environment and ins tallation practices thorough consideration before plugging in the Omnia.ONE (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.

http://www.telos-systems.com/techtalk/surge.htm

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 twoscrew mounting arrangement will prevent di s tortion of the front pa nel!

Adequate ventilatio n 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–sen si ng, hi gh -efficie ncy switching power suppl y 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 wi th loc a l e le ctrical regulations.

After power is first applied to the Omnia.ONE, the LCD scr een, 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.

Rear Panel Connections

Analog Audio Inputs and Outputs

Balanced XLR-type connectors are used 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 “Input Src” (Input Source) software parameter setting in the Input submenu of the Input/Output 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.ONE) differs from that of your exis t ing syste m, your announcers may feel that they sound “weird” i n their headphones. If this occurs, then the relative phas e 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.

Stereo Generator Connections (FM Style Only)

Four standard female BNC connectors comprise the Omnia.ONE’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.

Composite Outputs 1 & 2 ( BNC) (Active on FM and SG Styles Only)

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 leve ls 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 excite r 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.

Jumpers JP7 & JP8 are also available if you need to limit the maximum peak-to-peak output voltage fro m t he composite outputs to 4v p-p instead of the normal 10v p-p. They de fault to the Normal (10v p-p) setting.

19 kHz Sync Output (BNC ) (Active on FM and SG Styles Only)

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 fre quency 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) (Active on FM and SG Styles Only)

Any SCA or RDS signal above 53 kHz can be added to the composite outputs of the Omnia.ONE 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 inject ion level can be adjusted using the rear panel Gain trimpot.

AES/EBU Digital Input, AES/E BU 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. SYN C ) use industry-familiar RJ-45 connectors and utilize the StudioHUB+ wiring standard

. 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 is one AES-3 output on a standard RJ-45 connector that provides either an inter nally generated output sample rate of 48 kHz or the sample rate can be locked to an external AES/EBU signal applied to pins 3 & 6 of the the AES IN / SYNC IN connector or to the AES/EBU input signal. These options are selectable using the “Samp. Rate” setting in the Output submenu of the Input/Output menu.

Note: The analog and digital outputs are active simultaneously.

More information about the StudioHU B+ wiring scheme can be found at: http://www.studiohub.com/

For your convenience, two XLR adaptor cables are supplied with the unit. The male XLR lead with the GREEN shrink tubing is used fo r AES OUT. The male XLR le ad 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 l ead with the RED shrink tubing is used fo r AES EXTERNAL SYNC IN.

Ethernet / Livewire Connection

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

Ethernet 10BaseT/100BaseT Remote and Livewire I/O

RS-232 Modem Connectio n (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 ter minal pr ogram along with an internal RS-232 connector for troubleshooting purposes.

RS-232 Modem Port

NOTE: Yo u must use a standard straight-through serial cable and not a null mode m cable when c onnecting the RS232 connector of the Omnia and the external modem. Typically this would be 9-pin to 25-pin cable. (External modems trad i tionally have 25 pin c onnectors i n "DCE" configuration. The Omnia.ONE has a 9 pin in "DTE" configuration, so the standard 9-pin to 25-pin cable will work).

The setup and operation of the Omnia Remote Control application is covered i n detail in Appendix C.

*Please note that the RS-232 Modem functionality is not yet i mple mented 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-9F)*

This DB9-female connector serves as a four-input, op toisolated interface to the Omnia's int e r nal GPI functions. Four of the pins are “ground-sink” inputs, one is a bias voltage input, one is a +5V power output, and the remaining three are “ground .” The inputs can be used to dynamically alter the Omnia.ONE’s operation in response to logic transitions on the interface connection.

Full details, including connector pinout, are covered in Appendix D, starting on Page 147

DB-9M GPI “Interface” Connector

Powering Up

Now you are ready to power up the Omnia.ONE for the first ti me. Connect AC power to the unit using the appropriate supplied power cable for your location. (There is no power switch!)

When the Omnia.ONE is first powered on, audio will appear at the analog audio outp uts in approximately ten seconds. The AES/EBU and Livewire outputs also become usable at this time however full initialization of the digital ports is not complete for sever a l 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:

Chapter-2: Getting To Know Your Omnia.ONE

The Omnia.ONE User Interface

Now that yo ur Omnia.ONE is rack-mounted, connected to a program audio source, and turned on, you’re ready to learn how to operate it! This chapter covers the Front Panel User Interface, your window into the Omnia.ONE processor.

A front panel jog-wheel with integral p ush switch, LED bargraph peak-reading level meters and a backlit LCD display that is switchable between menu and AGC/Limiter metering screens make up the primary Omnia.ONE User Interface. The front panel menu access may be password protected to prevent unauthorized tampering with processing or p resets.

Omnia.ONE Key Front Pane l Fe atures

Headphone Jack Headphone Level Control Jog Wheel

Main Menu / G/R Metering LCD Display Level Meters

Headphone Level Control

A standard ¼" TRS stereo headphone jack is located at the left side of the front panel and allows the processed signal to be monitored. The Headphone volume level control is physically located to the right of the headphone jack. The headphone amplifier itself is a high-headroom design and is driven by its own high quality D/A converter that is independent of the anal og XLR outputs. Therefore level changes in ei t her output will not affect the other.

Level Meter s & Processing Bargraphs

The top two of the three horizontal meters show digital sample-accurate peak representations of the left and right channel input or output levels. Whether thes e bargraphs are displaying Input, Analog O utput, AES/EBU Output or Livewire Output levels is selectable from within the Input/Output menu. A front panel i ndicator confirms which level view has been selected, Input or Output.

The bottom horizontal meter (marked “comp / aux”) displays the composite MPX level from the stereo generator before the output level controls. (Active on FM and SG Styles Only)

Audio I/O Le vel Display

Either input or output levels can be displayed on the top 2 (L & R) meters. The highest LED illuminated indicate s digital sample-accurate peak signal levels. The meters are calibrated in dec ibels below full scale digital (0 dBFS) in 2dB steps. 0 dBFS is the absolute maximum level in the digital domain. Levels from –34 dBFS to –14 dBFS are displayed in blue, levels from –12 to –2 dBFS are displayed in yellow and 0 dBFS (the clipping point) is displayed in red. The bottom meter displays the composite MPX signal level referenced to 100% modulation (FM and SG Styles Only).

Processing Me te r Dis play

In “Meter Display” Mode the vertical bargraphs show all of the processing activity (the amount of gain reduction) in the AGC, Limiter and Clipper sectio ns within the Omnia.ONE. (varies with style) If the “Menu Display” is currently showing on t he Omnia.ONE’s LCD screen, press and hold t he jog-wheel for two seconds to switch to the processing meter display as shown below.

To return to the Menu display, simply click the jog wheel once. (See “Using the Jog Wheel

Important Notes:

• A solid white bar will drop downward from the top to display the amount of gain reduction in each

processing band. The change from a solid bar to a checkerboard pattern indicates a “gated” condition in that band .

• The wideband AGC and four-band AGCs will recover to a resting gain setting which coincides with

the RTZ (Return To Zero) levels set for each band.

• The Clipper meters are peak reading, showing the maximum amount of clipping that occurred over

the past 30 milliseconds. The Main clipper meter (FM & AM Styles Only) will indicate higher amounts of clipping on bright program material because the Main Clipper is operating on the preemphasized audio signal. This is normal and does not indicate the perceived amount of audio distortion.

Main Menu

The Omnia.ONE menu system has been designed to be intuitive and simple to use. Most operating parameters can be found under one of the menu headings and sub-headings, allowing adjustments to be made quickly and with ease. Rotating the jog-wheel s equentially highlig hts each menu item in turn. (See “Using the Jog Wheel

When the jog wheel is pressed inward (clicked) while a menu item is hig hlighted it will open that item’s submenu. Similar behavior occurs when selections are made within the various submenus.

To return to the previous level, rotate the jog wheel until <-Exit is highlighte d and then press the jog wheel inward. (Click) This will return you to the next highest level in the menu structure. NOTE: Some of the l onger men us have an <-Exit option at the to p of the menu as well as at the bott om.

” on Page 10)

The Omnia.ONE Main Menu offers five selections

• Preset

• Processing

• Input/Output

• Administrative

• Lock Front Panel (not visible in the above screenshot)

Using the Jog Wheel

The main user control for the Omnia.ONE is the easy to u se jog wheel with its integral push-switch. Using the control is both intuiti ve and effici ent, making it easy to navigate the menu structure of the Omnia.ONE. Processing changes and system adjustments can be quickly made with ease without having to remember multiple controls, their positions, and what they do in each menu. T he behavior of the Omnia.ONE's menu system is consistent across pages and is easy to learn. We believe that you will quickly become comfortable with how it works, and appreciate its simplicity.

Clockwise rotation moves the highlighting in a menu downward and increases a value when editing parameters.

Counterclockwise rotation moves the highlighting in a menu upward and decreases a value when editing parameters.

Pressing inward on the jog-wheel activates the Enter, Return or Select button function as follows:

Pressing the jog-wheel inward once (also called “clicking”) selects the highlighted menu item or accepts the current parameter value. Think of it as a vertical mouse button.

Pressing and holding t he jog-wheel in for two seconds will switch the L CD screen to a display of the processing meters so that the gain-reduction activity of the AGC and Limiter sections can be monitored.

Clicking onc e when the metering screen is displayed will r eturn the d isplay to the menu scre en.

User Interface Tutorial – Input Source Selection and Peak Level Se tting

wheel to display it.

The following two exercises are a useful introduction to the user interface. Start from the Main Menu (as displayed when the unit is first turned on).

The first exercise changes a parameter selection (the Input Source selection):

 Rotate the jog-wheel to highlight Input/Output.  Click the jog-wheel (push on the wheel once until a click is felt and release) to bring up the Input/Output

menu.

 Rotate the jog-wheel to highlight Input and cli ck.  Rotate the jog-wheel to highlight Input Src and click.  The factory default selection for Input Source is Analog. To change the input selection to AES /E BU digital

or Livewire, rotate the jog-wheel un til [AES/EBU] or [Livewire] is displayed and click. If you are using the analog inputs, rota te the jog wheel to display [Analog] and click to reselect the analog inputs.

 To return to the top level of the Main Menu, rotate the jog-wheel to highlight <-EXIT and click. Repeat

until the top level (Main Menu) is reached. NOTE: Many of the Omnia.ONE’s menus have an <-EXIT selection at both the top and bottom of the menu.

The next exercise adjusts a parameter that uses a value (the analog master input level setting):

 The Main Menu display should still be showing on the LCD scre en. If not, click the jog-  Highlight Input/Output and click.  Highlight Mtr Select, click, rotate the jog wheel until [Input] is displayed and c lic k. This sets the first 2 LED

meters to monitor the Left and Right channel input levels.

 Rotate the jog wheel clockwise to highlight Input a nd click.  Rotate the jog wheel to hig hlight Anlg Level and click the jog-wheel to select the control.  Rotate the jog-wheel CW to increase the input level. Rotate the jog-wheel CCW to decrease the input level.

This control adjusts b oth channels t ogether i n precise 0.5 dB steps. The gain in dB is shown to the right of t he “control.” Watch the Left and Right channel LED meters while adj usting p e r the following section below.

Proper Setting of Input Le vels

With normal program audio levels applied, a correct input level setting will result in peak indications on the L & R LED meters achieving –12 dBFS or a little higher (just into the yellow). This gain setting corresponds to system headroom of about 12 dB. You may adjust the input level lower for more headroom if you wish. Setting the input level for higher meter indications (less headroom) is strongly discouraged unless t here is another level-control device prior to the Omnia.ONE that will keep the input levels from reaching the maximum digital level of 0 dBFS. During normal operation, you should never see the red “0” segments light.

 Once the desired level setting is reached, click the jog-wheel to accept that value. This returns the jog-wheel

to Select Mode.

 You may highlight a nd click Right Trim to adjust its gain separately from the left channel if the input source

is not well balanced. In this mode the right channel gain can be adjuste d over a range of plus and minus 3 dB
