  • Page 9: Sensus® Technology: Audio Processing X3

    .Multicast 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...

    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.

  • Page 11: So... What's So Smart About Sensus

    ® 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! The result is consistently high audio quality through a codec-based system, even at very low (18kbps –...

  • Page 21: Rs-232 Modem Connection (Db-9M)

    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.

  • Page 22: 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.

  • Page 24: Audio I/O Level Display

    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.

  • Page 25: Using The Jog Wheel

    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.

  • Page 26: 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.

  • Page 27: Proper Setting Of Input Levels

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

  • Page 29: Chapter-3: Getting The Sound You Want

    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.

  • Page 30: Increasing Density/Loudness

    Once you have satisfactory results in one area (like overall density) you can then move the focus to the next area that you feel needs more tweaking.

  • Page 31: Adding More Detail-When Loudness Isn't The Last Word

    AGC sections. Changing the relative amount of Drive to the individual multi-band limiters. Adjusting one or more bands to have faster release times than the others. Adjusting the settings within the Mixer. All four options will provide a noticeable change in EQ and each will have a different character. We suggest you use the first two listed options before trying others.

  • Page 32: Thunder Bass

    If everything is working properly the vocal quality should not change due to the coding process. If this is noticed, try reducing the Sensus® function value by one adjustment click and then reevaluate.

    OmniaONE: 24, 32, 48 and 64 kbps. By starting with one of the factory presets (usually the one named closest to the primary programming and bitrate to be used on the channel the OmniaONE Multicast is processing) and then altering it using the controls in the Processing menu, you may change the sound of a preset and then save it with your changes as a user preset for either immediate use or later recall.

    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.

  • Page 36: Wideband Agc (Automatic Gain Control)

    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.

  • Page 37: Enhancers

    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. The addition of these overtones causes small speakers to seem to produce bass response that they are not actually capable of producing because the human brain equates the presence of low frequency harmonics to the missing fundamentals that the small speaker is unable to reproduce.

  • Page 38: Low Band Agc

    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.

  • Page 39: Mid Band Agc

    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 –...

  • Page 40: Mid Band Limiter

    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’...

  • Page 41: Mixer

    The drawback is that it can generate intermodulation distortion in the Final Limiter and increase artifacts in the codec employed after the Omnia ONE Multicast. When both the Girth Clip and Tight Clip settings are both set to “OFF”, the Bass Clipper is effectively bypassed.

  • Page 42: Sensus

    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®...
  • Page 43 OmniaONE Multicast offers this feature as a low pass output filter that can be set to one of seven stop band frequencies. Each of the filters possess minimal passband ripple and are phase linear below cutoff. Response in the filter stop bands is greater than -100dB.

  • Page 44: Exit

    The Nyquist Theorem states that the maximum frequency that may be applied to a sampled data system is one half the sampling frequency. When signals beyond half the sampling frequency are present, aliasing occurs which causes the appearance of an inverted spectral image of the audio spectrum to be “folded around” the...

  • Page 45: Mtr Select (Meter Select)

    Failover Time is a feature that when set to a value other than zero (disabled) allows the OmniaONE to automatically select another input source if the currently selected one fails. Failover Time is the amount of time that will elapse after the failure of audio on the primary input source before the unit makes the decision to switch to the secondary (failover) input source.
  • Page 46 “Both” is typically selected if it sounds “better” to an announcer (monitoring themselves in headphones using the output of the processing) than “None”. One of the two settings should. The goal is to make the relative phase of the headphone feed more in phase with the announcer’s own bone conduction.
