Omnia-6EX Quick-Start Setup Guide We know that you’re probably in a hurry to get on the air with your new Omnia 6. If you have technical expertise and previous knowledge of audio processor fundamentals, using the following Eight-Point Quick-Start Checklist will get you up and running as quickly as possible. -
Page 16: Omnia-6Ex Pre-Installation Tasks
Chapter-1: Pre-Installation Even though we believe the Omnia-6EX is the easiest processor to install in its class, 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-6EX processor. Note that there are additional installation and operation tips presented in Chapter 4 that may pertain to your specific installation. -
Page 17: Ac Environment Considerations
The Omnia-6EX also contains a third PC Memory Card slot that is used to load software for the Front Panel. The slot is located under the top cover on the right-hand side of the Front Panel circuit board and is normally un- occupied. -
Page 18: Installation And Connections
The Omnia-6EX requires 3RU (5.25” [37 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 two-screw... -
Page 19: Audio Inputs
During system power-up, the front panel LCD screens display several status screens while the operating software and DSP code is loaded. Once the main Omnia-6EX Main Menu is shown on the right screen, and the Meter Screen is shown on the left display, the unit is ready for use. -
Page 20: 19 Khz Sync Output
SCA Input (BNC) (FM Mode Only) Any SCA signal above 53 kHz can be added to the composite outputs of the Omnia-6EX by connecting the SCA signal to the SCA INPUT connector. The SCA signal is mixed in the analog domain directly into both composite outputs. -
Page 21: Interface Connection
Interface Connection (DB-9M) This connector is the interface to the Omnia's internal trigger script function. Eight of the pins are “trigger” inputs and the remaining pin is the ground reference. The trigger inputs can be used to dynamically alter the Omnia-6fm’s operation in response to logic signal transitions at the interface connection. -
Page 22: Powering Up
Powering Up When the Omnia-6EX is first turned on, there is a few seconds of delay as the system starts up. You should notice revolving Omnia logos on the screens, and then the main screens should appear. After approximately ten seconds, audio will be present from the analog, composite and headphone outputs. The AES/EBU outputs also become usable at this time. -
Page 23: The Omnia-6 User Interface
Chapter-2: The Omnia 6 User Interface Now that your Omnia-6EX 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 Graphical User Interface, your window into the Omnia-6EX processor. -
Page 24: Using The Jog Wheel
Using the Jog Wheel The main user control for the Omnia-6EX is the large, easy to use jog wheel with its integral push-switch. Using the control is both intuitive, and efficient, making it easy to navigate the menu structure of the Omnia-6EX. 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. -
Page 25: Level Meters And Processing Bargraphs
The thirteen vertical bargraphs in the lower half of the Meter Display show the processing activity in real time within the Omnia-6EX. The first vertical meter (labeled W) represents the processing activity in the Wideband AGC section. The five vertical “AGC” meters show the processing activity of each of the AGCs in the multi-band AGC section. -

Clicking a highlighted item selects it; when that item is a control, the jog- wheel adjusts the value or level.
-
Page 31: Menu Overview
Highlighting Preset and clicking the jog wheel will open the Preset submenu. Appearing here is a list of all of the presets stored on the Omnia PC Card. Highlighting a Preset and clicking “Choose” allows that preset to be loaded into the Omnia-6fm, instantly setting the various processing parameters. You may also compare and modify settings between presets, save the current processor settings to an existing or new user preset, rename or delete user presets and password protect user presets using options found on this submenu. -
Page 32: Input & Output Submenus
Like the Input and Output menu choices, these menu items are typically adjusted during installation, and are saved as a System Configuration (see above). See Page 42 for full details. Encode Submenu Omnia-6ex Use and Operation Manual – V: 1.10... -

Page 39: High Pass Filter
3. Audio must have actually been ‘detected’ first on an input before the Hunt process can function. Said another way, if the Omnia is sitting on the workbench with no audio applied and the Auto and Hunt options are enabled, nothing will happen. The Omnia needs to see valid audio FIRST before it can detect the absence of audio and begin the Auto switch phase. -
Page 40: Output
The control range is from –2.0 dBu (-24 dBFS) to +22 dBu (0dBFS) peak output level in precise 0.1 dB steps. Since the Omnia defines the absolute peak levels prior to this control, this level control is normally set to the maximum acceptable input level, or just below it, of the device that Omnia-6 is driving (STL, transmitter, etc). -
Page 41: Multiplex Power Limiting
In certain parts of the world, the average multiplex signal power must be controlled to reduce adjacent channel interference. The currently enforced standard falls under the ITU BS-412 regulations. The Omnia-6EX has a very effective Multiplex Power Limiter that may be enabled to comply with these regulations. -
Page 42: Encode
Clipping control before adjusting the composite outputs. Note that reference line-up tones applied at the Omnia-5EX input cannot be used since the RMS level of a steady state tone does not crest at 100% modulation. -
Page 43: Separation
The Omnia-6 defaults to a setting of Stereo, using the full L-R signal. We suggest that you leave it in that mode, but the other settings are available for those who wish to experiment, including a setting of Mono. -
Page 44: Save To Card
Save to Card Stores the Schedule and daypart information on the Omnia PC Card. You might do this for safety or even for sharing the data with other Omnia-6 processors. It saves all of the currently defined dayparts and the daypart state to the Omnia PC card. -
Page 45: Backlight
To maintain accurate dayparting, you should periodically reset the internal clock to your external reference. The Real Time Clock IC used in the Omnia-6EX typically has an accuracy of better than +/- 0.5 minutes per month. -
Page 46: Lock Unit
Reset Passwords If front panel passwords for levels 1 and / or 2 are lost or forgotten, it is possible to reset the Omnia’s passwords back to their factory defaults. When the Reset Passwords box is clicked, you will be prompted for the current level 3 password. -
Page 47: Security Config
Security Config Submenu The Omnia now has the NTP (Network Time Protocol) function built in to enable it to retrieve the time of day from an external source and keep the Omnia’s clock set very accurately over the long term. Both long and short term timekeeping are enhanced by this feature. -

Full details about all of the individual controls in the Process submenu can be found in Chapter 5: “Fine Tuning Your Sound”... -
Page 50: Wideband Agc
Wideband AGC: A very flexible wideband leveler section provides smooth, transparent control of the input program. This is achieved through two significant Omnia innovations, a dual referenced release gate and a hidden, intelligent “makeup” gain algorithm. The dual gate reference is a unique process that correlates the dynamics of the audio input signal to a “rolling”... -
Page 51: Phat Bass Eq
(or “phatter”) with the illusion of added loudness. The pleasing low frequency harmonics generated by the Omnia's Phat Bass algorithm helps your station sound bigger and fuller on radios with smaller speakers, such as portable or desktop radios. This gives your listeners the illusion of deeper bass response from their radios than they're actually capable of. -
Page 52: Look Ahead Limiter
New in Omnia-6EX is a pilot notch filter to protect the pilot region from clipper artifacts. The wide, deep notch helps the stereo pilot region stay immaculately clean, reducing multipath, and keeping receiver's stereo decoders firmly locked to your signal. -
Page 53: Processor Interfacing
These sections can add significant distortion and modulation overshoot if not set up properly. If a composite STL is used, the multiplexed output of the Omnia-6EX can be connected directly to the STL. At the transmitter location, the composite receiver can be directly connected to the exciter. -
Page 54: Digital Stl Use
However, the Omnia- 6EX can be placed at the studio if you follow a few guidelines and are willing to accept some limitations. (See “Interfacing with a Digital STL and/or Exciter” below.) In this scenario, there also must be a provision for a stereo generator/encoder at the transmitter (most digital exciters provide this function);... -
Page 55: Processor Latency / Time Delay
We have measured the propagation time delay, the amount of time it takes for the audio signal to travel from the input of Omnia-6EX to the output at approximately 9ms at 1khz. This is enough for a slight voice- character coloration to be audible to the person speaking, but usually not enough to be a problem for talent monitoring off the air. -
Page 56: Omnia-6Ex Connections
In the Omnia-6EX Input menu set the Pre-emphasis “ON” at the correct value for your country. In the Output Menu, set the De-emphasis option to “OFF”. -
Page 57: Pre-Emphasis: Where To Insert
When using the AES/EBU outputs to drive a digital STL or exciter, your Omnia-6EX’s sampling rates must be set to match the lowest internal operating sampling rate used in any device which follows the Omnia-6 in the audio chain. You will find these options in the Output Menu; available selections are 32kHz, 44.1kHz, 48kHz, and 96kHz. -
Page 58: Output Connection Options (Hd Mode)
HD Mode (Digital Channel) Output Connection Options The Output Menu contains a virtual patch bay for assigning the Omnia’s three different outputs to its two main processing chains. Note that the two Composite MPX Outputs are always connected to the conventional FM processing blocks. -

Be careful. Having said all of this, we firmly believe that Omnia-6EX will get you closer to your ideal than any other processor or combination of processors available today. It is definitely capable of generating moment-to-moment loudness; it has the muscle. -
Page 61: Adjustment Procedure
+0.5 dB or - 1 dB, or in 1 or 2 step increments. Try turning different functions on and off. Working this way, you will be able to get a better feel for the sound that the Omnia-6EX is capable of producing on your station and with your programming. -

“rest” with the main bargraph. This action will be easily noticed on material that is very dynamic in texture. It is partly due to this very special behavior that the Omnia-6EX has the musicality and clarity that other processors lack. -
Page 63: Interpreting The Meters
Conversely, audio signals with a wide dynamic range possess a higher peak to average ratio. The Omnia-6EX adapts differently to each case. -
Page 64: About Factory Presets
6EX’s processing. Omnia/Telos does not warrant in any way that these presets are de facto standards for the format names that we used when we designed them. The factory presets were created as starting points, typical of the on-air sound that might be typical with such format names, but they are not engraved in stone! For instance, the technical sound of CHR stations usually varies from market to market, even though the overall playlist doesn't. -
Page 65: Loading A Preset
Once you have highlighted the desired preset name, just click once to load that preset into the Omnia-6EX. To exit the preset selection list, rotate the jog wheel counter-clockwise until the <Exit> option is highlighted. Then click once. -
Page 66: Parameter Editing
Omnia-6 jog wheel and click functions work. If so, you’re ready to tackle Omnia-6’s more sophisticated adjustments. To edit a preset it must first be loaded into the Omnia-6. Once loaded, it can be modified as required to suite your tastes and processing goals. -
Page 67: Adjusting The Wideband Agc
How quickly the target gain reduction level is reached, is set by the remaining RTP Speed settings (Slow, Medium or Fast). If no RTP gain reduction is desired, use the RTP Speed setting Freeze. Omnia-6ex Use and Operation Manual – V: 1.10... -
Page 68: Adjusting Agc Crossovers
Simply use the “-15” setting in this case to have the gain return to –10 dB when gated. Note that ratios are critical to the open and musical sound of the Omnia-6EX, and therefore we do not offer them as user adjustments. -

(less gain = more gain reduction) than might be achieved if the control was set to Freeze. This will reduce hiss and other high frequency noise. The RTP levels can be tailored for each individual AGC band as desired. Omnia-6ex Use and Operation Manual – V: 1.10... -
Page 70: Adjusting The Agc Mixer
Simply use the “-15” setting in this case to have the gain return to about –10 dB when gated. Note that ratios are critical to the open and musical sound of the Omnia- 6EX, and therefore we do not offer them as user adjustments. -
Page 71: Adjusting The Enhancers
Enhance Submenu Deep Bass EQ: For those who demand thunderous bass, the Omnia-6 has it! Up to 12 dB of “thunder” can be added to shake your listener’s walls! This is not a simple bass boost, but a rather sophisticated concept that takes into consideration the time alignment of the low frequencies as they pass through the entire Omnia system. -
Page 72: Adjusting The Limiters Crossover
If you are familiar with the limiter section in the Omnia Classic, you'll remember that significant gain reduction was necessary in order to achieve extreme loudness. That is NOT the case with Omnia-6EX! The limiters are true limiters, and therefore don't need to do much work after the multiband AGC section to create a huge signal on the dial. -
Page 73: Adjusting The Multiband Limiters
Usually, the limiter thresholds are adjusted as a “fine polish” on the final sound. If you are unsure about how to use the Limiter Thresholds, then we recommend that they be left at their well-researched factory settings. Omnia-6ex Use and Operation Manual – V: 1.10... -
Page 74: Adjusting The Final Mixer (Lim Mix)
AGC or Limiter X-Over menus instead of the limiter mixer controls. Like the limiter threshold controls, the final limiter mixer is mainly for minor “fine polish” to the overall sound. Adjustments in this section must be done with care. Omnia-6ex Use and Operation Manual – V: 1.10... - Page 75 The action of either of these can be further tailored using the Bass Clip Tune that was previously explained. Clipper Drive: Here is where the Omnia-6EX's loudness versus quality advantage is most evident! The main clipper is a very powerful algorithm, is highly over-sampled, and is fully anti-aliased. This clipper control’s adjustment range is +/-6 dB, in 0.1dB steps.
- Page 76 Look Ahead Limiter (HD Mode Only) Look Ahead Limiter Submenu Omnia-6EX employs a Look Ahead limiter to provide absolute precision peak control for the HD Digital Channel. This limiter has been designed to minimize processing side-affects like IMD, which are usually associated with limiters of this type.

Omnia-6EX has changed all of that! It's been designed to look at the incoming audio, and know how to make your station consistently loud on the dial, and without the artifacts or grunge created by your current processor. Omnia- 6EX makes loudness an effortless exercise for all formats. -
Page 82: Increasing Loudness

Page 89: Using A Direct Serial Connection
Using a Direct RS-232 Connection for Local Communications When a computer can be located near the Omnia-6EX, it may be convenient to use a direct serial cable connection rather than dial up. Use a standard, straight-through serial cable - null-modem cables will not work! A typical serial cable will need a DB-25 male connector for the Omnia-6EX end, and probably a DB-9 female connector on the computer end. -

The System Parameters are assigned to controls which govern overall operation, such as Input and Output Gains, Pre-emphasis/De-emphasis, etc. These parameters would NOT be saved with individual presets, but instead are saved using the Save To Card option in the System menu. -
Page 100: Creating A Trigger Script
This procedure can of course be done by manually using the Omnia-6EX front panel controls to turn off the 19 kHz pilot tone and to switch the input from stereo to mono left. But a far easier method is to use the Trigger Script Editor to create two scripts that can be loaded into the processor to run in response to a single relay contact closure or open. -

Omnia-6EX. And the eight relays or switches do not have to be switched locally: Commands can even be initiated by a network satellite when a receiver with contact closures is being used. -
Page 102: One Way" Scripts
Let's review what we created for the example we showed you under “Using the Script Editor”. Whenever pin 1 is held low (the contact or switch is in a closed state), the Omnia-6EX will switch to and stay in mono mode (no Pilot and only the left input channel is used). -

Another possible use of the one way Trigger Script script capability (although not strongly recommended) is the remote 're-booting' of the Omnia. In that special case, there would be no Go High script entry. The Go Low script for that function would simply read:... -

Once these parameters have been entered and saved as a connection profile, they can be used to capture and display (and print) the output of the Omnia 6's RS-232 serial port during boot up. See the next page for an example of a normal Omnia 6 boot up... -

Cause: This error may show up when the Omnia is booted up for the first time with a new rear-panel software card or when the Omnia booted up for the first time after the non-volatile memory (NVRAM) has been cleared, such as after replacement of the battery. - Page 108 Timed out loading DSP. Failed DSP #x Bootstrap, contact CE. Description: The operating system was not able to initialize one of the Omnia’s DSP cards or one of the two DSP IC's on the card. Cause: One of the DSP cards or DSP chips may have failed.

Page 109: Safety Note
Electrical and mechanical safety note! When the Omnia is operated with its chassis top cover removed, you are exposed to potentially lethal voltages and high speed rotating fan blades. Before attempting to make voltage measurements, be forewarned that the power supply heat sinks are connected to the AC power line. - Page 110 Motherboard related. Turn the power off and make sure that the rear-panel PCMCIA software card is fully inserted into the top card slot with the large Omnia label facing up and the version number sticker facing down. The PC Card is keyed to prevent improper insertion.

Intermodulation (IMD) distortion. This is why Omnia-6EX has AGC algorithms that are designed to carry quite a bit of the load for loudness processing. You can always drive the limiters harder if you wish, but it will be at the expense of that added busy sound due to the harder work that the limiters are doing. - Page 115 I make sure that the high-end is truly “silky-soft?” Omnia-6EX naturally offers a silky-smooth high end, but there are a few areas when you can further tame the high frequencies if desired. Before explaining this, we wish to say that the rumor that women listeners don’t like a bright high end may not be true! What they don’t like is a distorted high end.
- Page 116 10 and 11 o’clock) works extremely well. As of this writing, the only processing function that we don’t yet offer for the Omnia-6 is reverb. So, unless you desire that Boss Jock feel for a CHR station, where you need to operate a reverb in front of the Omnia, we feel that it should run barefoot.
- Page 117 It is designed to keep the on-air sound as close as possible to the source material. • Classical2: In this preset, we have re-tuned the Multi-Band AGC sections, resulting in less audible processing but more loudness and consistency than Classical1.

- Page 119 When would I use both? If I used both, what would be the amounts of each? The new Main Clipper in Omnia.6 is quite powerful!! All of the presets operate with a moderate amount of Main Clipping and the Composite Clipper is defaulted to the 0.0 or OFF position. In most cases, you will not need the Composite Clipper.
