Omnia-3 Quick-Start Setup Guide We know that you're probably in a hurry to get on the air with your new Omnia-3. If you have technical expertise and previous knowledge of audio processor fundamentals, using the following Eight-Point Quick-Start procedure will get you up and running as quickly as possible. Please refer to the remainder of the Operating Guide for additional information. -
Page 12: Chapter-1: Installation
Chapter-1: Installation Even though we believe the Omnia-3 is the easiest processor to install in its class, please take a few minutes to read through this chapter before proceeding with the installation. Pre-Installation Tasks This section offers common procedures for installing any version Omnia-3 processor. Additional model- specific information is given in the chapters on specific versions (Omnia-3fm Turbo in Chapter 4, Omnia-3am in Chapter 5 and Omnia-3net/drm in Chapter 6). - Page 13 Important Note 1: The PC Card used in the Omnia-3 is not a generic PCMCIA cards that can be bought in any local computer store. They are cards that are specified by Omnia specifically for this product. If you need a backup card, please contact Omnia Customer Support to purchase an additional card.

Page 14: Installation & Connections
Rack Mounting The Omnia-3 requires 2RU (3.50" [89 mm]) of rack space. Rack mount the unit using four rack screws. It is preferred to leave at least one rack unit of empty space above the Omnia-3 to enhance ventilation and to prolong component life. - Page 15 This TTL-level 19 kHz square wave output can be used as the reference signal for any SCA generator that operates at 57 kHz or other multiple of the 19 kHz pilot frequency. Using the 19 kHz clock from the Omnia-3 stereo generator makes it much easier to phase lock the SCA signal to the pilot frequency.
- Page 16 This connector serves two important purposes: It can be used for a local, bi-directional computer connection with Omnia-3 Remote Control, or it can be used for troubleshooting and error code resolution. In the former case, Omnia-3 Remote Control software is utilized. In the latter, any terminal emulation program can be used.

Page 17: Powering Up
Press the “O” side of the switch to turn off the unit for servicing. When the Omnia-3 is first turned on, there is a few seconds of delay as the system starts up. An operating system start up screen is displayed. Under normal conditions it should appear as: Load Algorithm... -
Page 18: Chapter 2: The User Interface
Using the Jog Wheel The main user control for the Omnia-3 is the large, easy to use jog wheel with its integral push-switch. We believe that you will quickly become comfortable with how it works, and appreciate its simplicity. -
Page 19: Main Menu Orientation
When the processor is first turned on, several start-up screens are displayed. After ten to fifteen seconds the Omnia-3 Main Menu is displayed with a sliding menu bar along the right side of the screen to indicate your position within the menu hierarchy. A multipurpose help line is located at the bottom of the display. - Page 20 Input & Output Input Levels Output Levels Go to additional 3. Rotate the jog-wheel CW to scroll down to highlight Input Source. 4. Click the jog-wheel to select Input Source. An expanded edit box appears with the word ANALOG shown in large type (this is the default input selection). 5.

Page 21: User Interface Concepts
All of the Omnia-3’s software parameters are set in similar fashion through scrolling through menus and sub- menus to select which parameter to edit. The parameter choices or values are then selected by rotating the jog- wheel until the desired setting is displayed. -
Page 22: Bargraph Display Metering Screens
The screens available depend on the style of Omnia-3. All styles have the first I/O screen that shows the input and output levels. On Omnia-3am and net units there is one combined “Process” bargraph screen that shows the wideband AGC bargraph and three limiter bargraphs (four on the Omnia-3am). -
Page 23: Menu Descriptions
The process bargraphs indicate the amount of processing (gain-reduction) of the AGC and Limiter bands in the Omnia-3. Maximum indicated gain-reduction is 25 dB, which occurs at the bottom of the screen. The bargraphs also have a GATED indication as determined by the Gate Thresh or Hold Thresh setting for that band. -
Page 24: Audio Processing
Stereo Generator (Omnia-3fm Turbo only) This sub-menu has the adjustments for the SCA Level, Composite 1 & Composite 2 output levels, Pilot Level, Pilot Phase and Separation. Display This sub-menu has the adjustments for the LCD screen (Contrast and Backlight). Utility Numerous maintenance and utility functions are nested within this sub-menu. - Page 25 (decibels below Full Scale digital, i.e. the digital clip point) so be sure that peaks do not reach 0 dB regularly or distortion will result. Input Phase: If the relative phase relationship of the Omnia-3 is different from your existing system, it could cause your announcers to think they sound “weird” when monitoring through the system using their headphones.
- Page 26 The Stereo selection indicates that the processor will process a 2-channel stereo signal. Please note that the two channels cannot be separate un-related signals since the processing is stereo strapped. Mono L: The signal at the left input is fed to both the left and right channels of the processing. Mono R: The signal at the Right input is fed to both the left and right channels of the processing.
- Page 27 Save to Card: Saves system parameters to the PC card. This makes a “copy” of the system configuration that normally resides in the nonvolatile RAM within the Omnia-3, storing it on the PC Card. This simplifies getting back to a previous state after numerous system adjustments have been made, but you want to return.
- Page 28 Save to Card: Backs up daypart information onto the PCMCIA card (for safety and sharing with others). It saves all of the currently defined dayparts and the daypart state to the Omnia-3 PC card. These settings can be loaded later by selecting the Load from Card option.
- Page 29 Disable Remote: Allows the user to restrict access to a list of system parameters so that remote users won’t be able to change the selected parameters. When the Disable Remote option is selected, a list of the system parameters that are editable through the remote is displayed. When a parameter is selected, it is no longer editable through the remote command interpreter.

This is not some simple bass EQ, but rather a sophisticated concept that takes... - Page 31 Such a compromise results in the loss of phase linearity, which reduces clarity. In Omnia-3’s DSP implementation, the crossover network is carefully time-aligned so the recombined spectrum remains flat, regardless of the amount of gain control being applied within any band. This yields a phase linear response, so that no harmonic content is ever displaced in time.

Page 32: Chapter 4: Omnia-3Fm Turbo
If the STL is discrete digital and it employs “compression” (a data-reduction codec), the Omnia-3 must be located at the transmitter site to avoid the overshoots, distortion and audible side-effects of feeding a codec with a tightly peak-controlled and pre-emphasized signal. -

look very “square.” If it appears to “tilt” in any manner, then there is a coupling problem in the STL system. (We’d offer further information here on the “how and why” this occurs, but that could consume a whole chapter unto itself!) Simply stated, the problem could be due to either AC coupling in the STL system or “bounce”... - Page 34 However, it cannot make up for potential sonic degradations. This method is similar to Left/Right Analog above in that it is bypassing the Omnia-3’s excellent stereo generator (and composite clipper) relying on the stereo generator built into the digital exciter instead.

Page 35: Processing Presets
Try to remember that when “crafting” that special sonic personality for your station. Omnia-3 gives you the power to create a sound totally different from, and better than, your competitors. Enjoy that power! We could publish the entire preset list, but chances are that we will continue to develop new or modify existing presets. - Page 36 To set the Pre-Emphasis, rotate the jog-wheel to cycle through the three choices: None, 50 µs or 75 µs. Click the jog-wheel to set the pre-emphasis selection. Note: Normally, the None selection would not be used in FM transmission applications, but is provided in instances where processing of a flat signal is desired.

Page 40: Omnia-3Am System Adjustments
10kHz NRSC compliant low pass filter: Tilt EQ and Tilt Frequency Low frequency tilt and equalization controls have been provided after the Omnia-3 am clipper section in order to compensate for certain design deficiencies in older transmitters. Particularly in plate modulated AM transmitters, interstage audio coupling transformers, interstage coupling capacitors, the modulation transformer and reactor, and the type of coupling between them, all contribute to low frequency tilt performance. - Page 41 Tilt Equalization Adjustment Procedure Since the purpose of Low Frequency Tilt Equalization of an AM transmitter is to optimize its performance on low frequency, clipped audio waveforms, proper adjustment of the Tilt Equalizer is mandatory if optimum modulation performance (maximum loudness) is the goal. Overcompensation, by using too much tilt equalization, is actually worse than no tilt equalization at all because it further taxes the transmitter’s modulator and power supply.

Page 46: Chapter 7: Editing Presets
It can take some time, a good deal of serious time to optimize the audio processing for your station. We realize that in our business today, time is a precious commodity. But please don’t try to install the Omnia-3 in between other major projects or the week your boss or your assistant is on vacation. -
Page 47: The Processing Display
That can be frustrating whether the change made you station sound better or worse. Take your time with the Omnia-3. You have a great deal of processing power at your fingertips. In order for you to become “sonically” comfortable, you should learn the limits of each function. Try making changes in different operating levels. - Page 48 Through observation of the processing bargraphs, significant information can be acquired and analyzed about the audio signal on a moment-by-moment basis. Since Omnia-3 is capable of performing many different processing functions at different times, the display bargraphs may indicate various kinds of operation. This is based upon dynamic range differences in the program material.

Omnia-3 controls. (See Chapter 2, The User Interface) If so, you’re ready to tackle Omnia-3’s more sophisticated adjustments. To edit a preset it must first be loaded into the Omnia-3. Once loaded, it can be modified to your heart’s content. The changes can then be temporarily used, or they can be saved to the PC Card so they won’t be lost. - Page 50 Bass & Warmth Enhancement Deep Bass EQ: For those who demand thunderous bass, the Omnia-3 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 51 If your desire is to “EQ” the sound, you should perform that using the drive levels in the XOver menu, the individual limiter Drive controls (Omnia-3 fm Turbo style only), or a combination of both. This final mixer is mainly for minor “EQ” changes to the overall sound. Adjustment of this section should...
- Page 52 Final Limit (Omnia-3net/drm only) This is the final limiter that operates in place of the clipper on all of the other Omnia-3 styles. There are two controls here: With the first you can turn the final limiter ON or OFF. This should normally be left ON unless the equipment following the Omnia-3net/drm has a non-defeatable limiter or otherwise requires non-limited audio.

Omnia-3 has changed all of that. It knows how to get a station sounding loud without the artifacts or grunge created by your current processor when you try to make it loud. And Omnia-3 makes loudness an option for all formats. - Page 55 The drawback is that the density can cause listener fatigue over a prolonged period of time. While Omnia-3 is designed to minimize listener fatigue, it is capable of generating large amounts of density that could eventually lead to fatigue. Be careful!

Page 70: Creating A Trigger Script
This procedure can of course be done by manually using the Omnia-3 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. - Page 71 1 (pin 1) and ground (pin 5) on the Interface connector on the processor's back panel. Setting the relay or switch on (shorting pins 1 and 5 together), then causes the Omnia-3 to follow the script for go low (the unit switches to Mono Left/Pilot off operation).
- Page 72 (ground). To execute a Go High script, the ground is removed from that pin. Each of the trigger pins (1, 2, 3, 4, 6, 7, 8, 9) is thus connected through a switch or relay to the Omnia-3’s ground on Pin 5.

- Page 88 This procedure can of course be done by manually using the Omnia-3 front panel controls to select a new input source, then individually adjust the left and right input levels. But a more useful 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.
