.Multicast Sensus® Technology: Audio Processingx3 Overview Until now, digital signal processing has been a more precise numeric implementation of well-known analog methods.
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.
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.

OmniaONE Multicast - Use and Operation Manual – Version 0.
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.
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.
Rear Panel Connections 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 are designed for standard +4dBu balanced signals. Pin 2 is Hot.
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 standard1. 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.
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.1 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.
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.
Chapter-2: Getting To Know Your OmniaONE The OmniaONE User Interface Now that your OmniaONE 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 OmniaONE processor.
Audio I/O Level Display Either input or output levels can be displayed. The highest LED illuminated indicates digital sample-accurate peak signal levels. The meters are calibrated in decibels 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.
Using the Jog Wheel The main user control for the OmniaONE is the 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 OmniaONE. 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. The behavior of the OmniaONE's menu system is consistent across pages and is easy to learn.
Main Menu The OmniaONE menu system has been designed to be intuitive and simple to use. Most operating parameters are found under one of the menu headings and sub-headings, allowing adjustments to be made quickly and with ease. Rotating the jog-wheel sequentially highlights each menu item in turn. When the jog wheel is pressed inward (clicked) while a menu item is highlighted it will open that item’s submenu. Similar behavior occurs when selections are made within the various submenus.
¾ The factory default selection for Input Source is Analog. To change the input selection to AES/EBU digital, rotate the jog-wheel until [AES/EBU] is displayed and click. If you are using the analog inputs, rotate the jog wheel to display [Analog] and click to reselect the analog inputs. ¾ 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.

Chapter-3: Getting The Sound You Want In general, applications requiring audio processing prior to a codec don’t rely heavily on absolute loudness for their overall success. Loudness is still important of course – you do want to be heard – but it is not the most important thing.
The following sections are provided to assist you in designing the personality of your sound. As we said earlier, there is no precise recipe for setting up audio processing because each application is different. However there are a few basics that we can share with you that can help get you to where you want to go.
Some users prefer their processing to be perceptibly loud but very dynamic. While this may not result in the loudest sound, it gives the illusion of competitive loudness while still retaining a lot of detail and clarity. To achieve this sound you should target most adjustments to the Limiter sections, and avoid heavy use of the Final Limiter and fast settings in the AGC sections.
The last option, adjusting the Mixer, is designed to provide a final minor trim to the audio spectrum. Since this stage is after all of the dynamic multi-band AGC and Peak Limiting, a radical change in level in the Mixer could result in excessive look-ahead final limiting in that band’s frequency range. We suggest that any changes implemented here be limited to about 0.5 dB to 0.7 dB of boost maximum.
Chapter-4: Main Menu Selections This section presents an overview of the five Main Menu items, (Preset:, Processing, Input/Output, Administrative and Lock Front Panel) their submenus (if any), and details about each of the adjustable controls within. Preset OmniaONE is equipped with a selection of factory presets that can be used to instantly configure the processing for common applications. The currently loaded preset is displayed to the right of Preset: on the top line of the Main Menu.
Save Preset This option saves any changes you have made to the currently running preset into the OmniaONE’s non-volatile memory. Changes can be saved over an existing user preset (without renaming it) or as a new user preset with a new name. You may not save a factory preset over itself with the same name and attempting this will generate the error message: “Cannot overwrite factory preset. Save preset with new name.” Presets can contain up to 10 characters.
Rename Preset A preset in the list of stored user presets can be renamed at any time. Factory presets cannot be renamed. To rename a user preset highlight Rename Preset and click. Rotate the jog wheel to display the preset to be renamed and click. Edit the preset name as described above in the Save Preset section. To exit without renaming the preset, rotate the jog wheel until *cancel* is displayed and click. <-Exit Click on this option to return to the Main Menu.
Wideband AGC (Automatic Gain Control) The wideband AGC rides the incoming audio levels like an automatic “hand on the fader”, keeping the average level more consistent for the following 4-Band AGC stage, enabling it to stay in its “sweet spot”. WB AGC (Bypass, Engage) The wideband Automatic Gain Control (AGC) stage can be bypassed if desired, although more consistency is achieved when this stage is used. AGC Drv (AGC Drive) This control adjusts the amount of drive to the wideband AGC stage.
Enhancers Deep Bass Adds ‘girth’ to the audio by enhancing very low frequencies such as kick drum fundamentals or very low bass notes that may be present in the input audio program. Phat Bass An Omnia exclusive, Phat Bass adds harmonic overtones to the lower bass frequencies.
Adjusts the amount of gain reduction in the Presence Band AGC. Higher numbers result in more drive and because of the increased compression, a more consistent output from the band. Hi Drive Adjusts the amount of gain reduction in the High Band AGC. Higher numbers result in more drive and because of the increased compression, a more consistent output from the band.
RTZ Speed (Return To Zero Speed) RTZ stands for Return To Zero. What RTZ does is return the gain of the AGC band to the selected amount of gain reduction (See RTZ Level below) in the absence of audio. RTZ speed controls how fast this adjustment takes place – i.e., how long it takes the AGC to move to the target RTZ level. RTZ Lvl (Return To Zero Level) This control adjusts the gain level to be achieved by the AGC section during lapses in audio.
The release control adjusts how fast the limiter recovers from periods of more gain reduction when the input audio levels fall. Faster release times (higher numbers) result in a more dense sound. Even though the Omnia uses program controlled release algorithms, setting the control for extremely fast release times while driving the limiter hard can result in ‘pumping’ as well as extremely dense-sounding (fatiguing) audio.
to the Mixer the same This allows you to reduce the Low Band Mixer control to reduce IM distortion in the Final Limiter without reducing the amount of perceived bass in the program material. Be careful! Too much clipping by the Bass Clipper can soften bass 'punch'. It may also be heard as a “rattling” sound in the bass or cause additional artifacts in the codec following the Omnia ONE Multicast.
Hi Band Adjusts the output level of the high band limiter into the overall mix. Higher numbers result in more high frequencies and too much mix level can make the following final limiter work unnecessarily hard. <-Exit Click on this option to return to the Adjust Processing submenu. Sensus® See a descriptive overview of the Sensus® function: Sensus (Technology: Audio Processingx3 beginning on Page 9. Sen Freq (Sensus® Frequency) This sets the range where the SENSUS® function begins its magic.
This type of peak controller is used instead of a clipper because it does not generate the same high levels of harmonic distortion as a Clipper does. This distortion would cause added difficulties in a coded audio system because the harmonics generated from the clipping action create added artifacts and workload in the encoder. These are especially annoying at high frequencies. There are tradeoffs in how each of these peak controllers sound when they are set to produce added loudness.
1 The Nyquist Theorem states that the maximum frequency that may be applied to a sampled data system is one half the sampling frequency.
This submenu provides level adjustments for the audio inputs and the absolute peak operating level of the Analog, AES-3 (AES/EBU) and Livewire outputs. Choices governing the selection of the input audio source (Analog, AES Digital or Livewire) and signal mode (Stereo or Mono) are also found within these submenus. These I/O settings are generally “set once and forget” parameters, usually adjusted during initial installation and then left alone.
Right Trim Allows a +/-3dB adjustment of the right analog audio channel gain to correct minor left/right balance problems in the input audio. The left channel analog input gain is not affected by this control and is set using the master Analog Level control previously described. AES Level (AES/EBU Level) Adjusts the master audio input level for the AES Digital input which is derived from the rear panel RJ-45 StudioHUB® connector.
[Mono L+R] - Configures the DSP processing chain to have both the Left and Right internal channels fed from the sum of the Left Channel and Right Channels of the input source selected. Note that this selection is active in all sources selected as Primary and Secondary (Failover) audio sources. [SWAP] - Configures the DSP processing chain to swap the Left and Right internal channels, that is, the DSP Left Channel is fed from Right Channel input and the DSP Right Channel is fed from the Left Channel input.
[Input] Slaves the output sample rate to the sample rate present on the Omnia’s AES digital input. Synchronization is possible over a range of sample rates from 32kHz to 96kHz. [Ext] (External) Slaves the output sample rate to the sample rate present on the Omnia’s AES SYNC input. Synchronization is possible over a range of sample rates from 32kHz to 96kHz. <-Exit Click on this option to return to the Input/Output menu.
