Now regarding your question Reduce the drive to the upper two bands of the Multiband Limiter section Start with a reduction of 1 0dB in each band Reset the Limiter Thresholds in both of these bands to 0 0 This will help soften and tame the high frequencies 4 Does the Composite Clipper contaminate the Stereo Pilot or RDS SCA spectrum NO One of the advancements that we introduced in Omnia 5EX is the ability to use composite clipping with no effect to the 19kHz pilot integrity The composite clipper is designed into the stereo generator and is implemented with a phase linear notch filter that has negligible overshoot lt 1 modulation After we re finished with the clipping function we insert the Stereo Pilot In essence we clean out the area for the pilot signal before inserting it By doing so all clipping artifacts are kept to a level 75dB below 100 modulation or 55dB below the pilot level This insures no interference to the pilot detection function in those radios that measure noise around the 19kHz region to decide when to activate the stereo blend function There is also a phase linear low pass filter at 54kHz used to remove harmonic content created by composite clipping This ensures that RDS and SCA signals can be utilized without interference from the action of the composite clipper This filter is a carry over from the original Omnia design and that filter design was based upon an older product of ours known as The

9. In fact the most common mistake that our first customers made when adjusting the Omnia SEX was overdriving the limiters A little goes a long way In fact it may help to think of them not as limiters but as Clipper Resource Allocators They should only do just enough work to keep the audio in each frequency band from driving the final clippers too hard and no more Omnia 5EX Use and Operation Manual V 1 1 72 Multiband Limiter Windows High Limiter H Limiter G R Attack Release ae Hold Thresh Limit Thresh Return to prior screen HEADPHONES Limiter Submenu SL Limiter shown as example The controls in these adjustment windows are similar in function to the previously described AGC stages However there are only four controls for the limiters The Attack and Release controls work similarly to the AGC sections but are of course much faster on overall action There are also two new parameters as well The first is the Hold Threshold This control sets the threshold where the limiter s Hold algorithm begins when it detects pauses in the audio When it s in the OFF position the limiters will attack and then release completely just as you would expect them to With Hold Threshold enabled the limiters will momentarily stop and rest during very short pauses especially during live speech Functionally this is similar to how the Gate function works in the preceding AGCs The other control is Limit Threshold This

12. Phase Linear Time Aligned Crossovers Most multiband audio processors make a compromise in the crossover area in order to provide a flat dynamic frequency response This is done to avoid audible peaks or dips in the recombined frequency response as the individual band gains change during processing In an effort to minimize this problem most processors use a fixed phase offset in the crossovers While such treatment helps to minimize frequency response peaks and dips it also results in a loss of phase linearity increasing smearing and reducing musical clarity In Omnia 5EX s DSP implementation the crossover networks are carefully time aligned so that the recombined spectrum remains flat regardless of the amount of gain control being applied within any band This true phase linear response assures that harmonic overtones are not displaced in time The result that truer more natural and more musical Omnia sound Additionally Omnia 5EX features separate crossovers for the multiband AGC sections The limiter section contains its own five way crossover with factory optimized non adjustable crossover frequencies and slopes Two Band AGC Similar in character to the wideband AGC described above but with two bands this section has the ability to add power and loudness to the audio while tailoring and pre processing it for delivery to the enhancement and multiband limiter sections Each of the four crossover frequencies has five user adju

25. control sets the threshold where audio peak limiting begins Care is needed when adjusting this control because raising the threshold counter clockwise causes less limiting to occur and the resulting uncontrolled peak energy will go to the clipper instead Thus with this control you can artistically trade off the dynamic limiting against brick wall clipping as each has its own sound As the limiter threshold is lowered by turning the Limit Thresh clockwise the peak output level of the limiter is reduced The signal in that band won t hit the clipper as hard and you ll notice more action on the limiter bargraph for that band In fact instead of reducing the output of one of the audio bands in the Final Mixer section you could instead dynamically reduce the level in that band which also increases density in that band by lowering the limiter threshold When adjustments are made to limiter thresholds start by making adjustments in 0 5dB steps Reducing the threshold too much can cause the system to create an effect that sucks out the frequencies in that band Conversely the opposite raising the threshold will create an exaggerated effect by over enhancing certain frequency ranges as well as causing increased distortion since excessive levels from that band will reach the following clipper stage Usually the limiter thresholds are adjusted as a fine polish on the final sound If you are unsure about how to use the Limite

Dividend 5 What pre processors would you suggest I put in front of my Omnia 5EX Actually none We don t wish to sound arrogant by saying this but if you look closely at the different sections of the Omnia4 5 you ll notice that we ve already designed it into the system in the form of a very effective broadband AGC One possible exception to this is in the case of STL systems where the Omnia 5EX will be located at the transmitter site and you need something to protect the STL from being over driven In those cases we know that the Aphex Compellor works extremely well As of this writing the only processing function that we don t yet offer for the Omnia 5EX 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 6 Why does the Omnia 5EX sound like it has so much more high end as compared to my old processor This is due to two distinct design features in Omnia SEX The method we use to perform the upper limiter function and where pre emphasis is added into the system both contribute to the Omnia 5EX s uncanny clarity Both of these features are significant advantages present in all Omnia processors Let s first discuss our limiter methodology Other processors usually employ a type of limiting algorithm known as feedback control While this function does a very nice job of controlling the audio signal it s done at the e

For the AES 2 output the output sample rate is set using jumpers on the internal SRC Sample Rate Converter board Interfacing With A Digital STL and or Exciter At the time of this writing many engineers are proponents of the all digital broadcast transmission path However there are some key issues which must be dealt with when implementing all digital transmission in order to preserve loudness without sacrificing audio quality One issue concerns the sampling rate of the audio processor and that of the exciter In order for two differently sampled systems to be interfaced in the digital domain a neat little device known as the sample rate converter is used For instance a device which outputs digital audio data using a 48 kHz or higher sampling rate can be converted down to a lower rate of say 32 kHz Unfortunately unless spectrum is limited to the Nyquist frequency of the lower rate overshoots can be created robbing you of loudness Detailed information can be found in the technical papers Critical issues and Considerations for an All Digital Transmission Path Digital Dynamics Processing It s All In The Samples and Digital Broadcast Audio Processing Finally The New Frontier on the Omnia Tech Info web page at http www omniaaudio com Omnia 5EX Use and Operation Manual V 1 1 56 When using the AES EBU outputs to drive a digital STL or exciter your Omnia SEX s sampling rates must be se

210. xpense of high Intermodulation Distortion Feedback algorithms are actually better suited for the lower Omnia 5EX Use and Operation Manual V 1 1 115 frequencies where any added intermodulation distortion creates a warming effect to the audio When used at the higher frequencies the sound of this algorithm type can be annoying as it sounds much more busy or squashed sounding The limiting algorithms in the upper two bands in Omnia 5EX use a feed forward design This algorithm type yields much lower distortion and thus it offers a far smoother more open and silkier sound The second difference is due to where we insert pre emphasis in our system Instead of inserting it before the multiband limiting section we do it after the limiters right before the clipper By doing this the system does not have to keep smashing the upper frequencies in order to control the pre emphasis energy In contrast the feedback method does this and it results in a dense and squashed sounding high end This was one of the original methods used to manage the pre emphasis energy and it works so one might wonder how we can insert the pre emphasis after the limiters and not generate unwanted high frequency distortion in the following clipper The answer is threefold First the RMS based AGC sections don t allow an unnatural buildup of high frequencies Second we alter the limiter thresholds to best manage the required pre emphasis boost Third our p
