46Sabine 2.4 GHz Smart Spectrum Wireless (BETA)14.1. Introduction to FBX®WHY FBX? Feedback is certainly the most perva-sive challenge to the audio industry. The potentialappearance of sudden, loud, out-of-control feedbackis every sound engineer’s and musician’s nightmare.Unlike more subtle audio quality problems or short-comings, feedback is embarrassingly obvious — itdisturbs the performer, the audience, and the techni-cian, and can damage equipment and just generallyruin your day.Feedback is a potential problem in any amplified soundsystem that places a microphone or pickup in prox-imity to a loudspeaker. Poor acoustical conditions ormisguided use by unsophisticated sound system op-erators only aggravate the situation. To make mat-ters still worse, a non-Sabine variety of wireless mi-crophone adds yet another level of feedback dangerto the picture. Since feedback erupts whenever thedistance, location, and gain relationships between aspeaker and a microphone reach a critical combina-tion, a mic that can move anywhere results in anever changing potential for feedback. A step in thewrong direction may change a clear sound to a pierc-ing shriek in less than a second.This enhanced potential for feedback with a wirelesssystem gets worse if lavalier microphones are used.Such microphones are usually placed farther fromthe mouth than handheld or head set microphones,thus requiring more gain. Also, the polar pattern of alavalier microphone is frequently omni-directional.Thus, the likelihood of feedback increases, due tothe microphone’s increased off-axis sensitivity to thesound emanating from the loudspeakers.The Sabine True Mobility™ SWM7000 wireless sys-tems solve feedback problems by precise attenua-tion of very narrow bands of feedback-prone frequen-cies. The process is automatic, simple to use, adapt-able to changing acoustical conditions and relation-ships, powerful in its application, and has minimalconsequences to the audio fidelity of the signal. Wecall this automatic filter a Feedback Exterminator®filter, or FBX filter for short.-10 dB cut at 500, 630, 1K, 1.25K, 1.6K & 2K HzIf the graphic EQ really had 1/3 octavefilter widths, the frequency response curvewould vary 6 dB between sliders. Thiswould ruin the sound.Graphic EQs usually use one-octave-wideoverlapping filters that provide muchsmoother frequency response curves. No-tice that the overlapping filters add to-gether to cut -16 dB when the sliders areonly pulled down -10 dB.FBX Feedback Exterminator® Theory & Practice14. FEEDBACK CONTROL THEORY & PRACTICEFig. 14a What a Graphi-Q does to your Program
47 Sabine 2.4 GHz Smart Spectrum Wireless (BETA)B4-SWM7000-OpGuide.pmd - 021022 - hto14.2. The Advantages of FBX FiltersBefore the invention of FBX, the most common device for controllingfeedback was the 31-band graphic EQ. However, an FBX filter offersthree distinct advantages over graphic filters.1. First and most obvious is the automatic nature of FBX filters. Whenfeedback occurs, FBX responds more quickly than even the mostexperienced engineer. Automatic FBX placement works even in thepresence of audio program material, intelligently distinguishing feed-back from music or speech.2. A second advantage is that FBX micro-filters areprecisely placed anywhere feedback occurs (with 1Hz resolution), while graphic EQ filters are limitedto 31 fixed center points. An FBX filter represents adirect hit on feedback! In contrast, a graphic EQfilter can only approximate the exact frequency ofthe feedback, and the filter (or filters) with the clos-est center frequency must be pulled down. Suchfilters are deepest at their centers, and such impre-cise attenuation takes a big (and unnecessary)chunk out of your sound (see figure 14b).3. Increased clarity and gain-before-feedback arefurther accomplished by the third and most impor-tant advantage of FBX: Sabine’s micro-filters are tentimes narrower than 31-band EQ filters. Using FBXmicro-filters will return up to 90 percent of the powerremoved by EQ filters.Here’s a good place to make a very important dis-tinction. Graphic EQ filters are typically called “1/3-octave,” but it’s important to understand that thisterm refers to the spacing of the filter centers (1/3-octave apart), and not the width of the filter (usuallya full octave). Graphic filters thus overlap one an-other, and affect frequencies well above and belowthe center point frequency, including frequencies ofadjacent bands. This makes graphic equalizers verypractical tools for shaping sound “with broadstrokes,” such as dialing in overall system EQ, butresults in destructive audio quality overkill when theyare used to eliminate feedback. A graphic equalizerwould need more than 10,000 narrow-band slidersto be as precise and powerful as your FBX.As an example of the power of FBX, figure 14c showstest results measured with a PA set up consistingof a microphone, mixer, FBX Feedback Extermina-tor®, power amp and two speakers. The system’sgain was first raised until the FBX removed nine feed-back points. Next, the FBX was replaced with a graphic EQ. The EQwas adjusted while the system gain was raised to the same levelachieved with the FBX. The frequency response curves of each devicewere then plotted and are compared in figure 14c. Note how muchmore of the program (the “good audio”) is eliminated using an EQ —whereas only feedback is eliminated using FBX filters.FBX Feedback Exterminator® Theory & PracticeThe grayareas showhow much ofyour program youwould lose using a 1/3-octave filter tocontrol feedbackYou get back thismuch sound & powerwith the FBX!FBX FilterFeedback!Fig. 14b - What FBX Gives Back to your ProgramFig. 14c - An Example of FBX at Work
48Sabine 2.4 GHz Smart Spectrum Wireless (BETA)14.3. Parametric Filters and FBXOf course, many savvy sound engineers, realizing the limitations ofgraphic equalizers in removing problem feedback, prefer to use a differ-ent type of equalizer, called a parametric EQ, for such applications. Ifyou’re one such audio engineer, you’ll be comforted to know that FBXfilters share much in common with parametrics.Compared to graphic filters, parametrics allow more precise adjust-ments — specifically, control of filter width, the amount of boost or cut,and the mid-band frequency of the filter. This greater precision, how-ever, comes at a price, as parametric filters are not nearly as intuitive orsimple to use as graphic equalizers.Nothing, however, is easier to use than an FBX filter, which enjoys theprecision of a parametric filter, yet deploys instantly and automaticallywhenever feedback is detected. Effectively, an FBX filter is a parametricfilter set to a tenth-octave width, restricted to cut-only activity, and au-tomatic in its choice of frequency band. If you want hands-on control,use the Sabine True MobilityTM Remote Software to change FBX filtersto parametrics, and tweak frequency, width, and depth to your liking.14.3.1. The FBX & True MobilityTM AdvantageAfter inventing FBX technology and refining it for over a decade, Sabinehas brought our patented automatic feedback control to its fullest real-ization with the Sabine SWM7000 True MobilityTM wireless systems.Our latest advance in maintaining the highest quality audio signal isdue to the placement of the signal processing in the input chain of themicrophone signal. Many times signal processing (compression andequalization) is placed after the output stage of a mixer, meaning it isapplied to a combination of inputs mixed together into one output andpassed through the processor. Particularly in the case of equalizationand feedback control, one consequence of such placement is that fil-tering appropriate to only one microphone may be applied to all mics inthe same mix bus. In other words, unnecessary filtering may be ap-plied to microphones that, due to variations in position and microphoneIt is common to describe a filter’s quality factor, or “Q,” as the center frequency of the filter divided by the filter width (in Hertz) measured atthe -3dB point. Filters that have the same Q, or width, at the -3dB point regardless of the filter’s cut or boost are called Constant Q filters (seep.14, Figure 6a). Filters that get wider as the filter gets deeper are called Proportional Q filters (see p.14, Figure 6b). Lately, however, thedefinition of Constant Q is becoming less distinct. Many equalizer manufacturers claim their equalizers have Constant Q filters, when in factthey get substantially wider as they get deeper. The only way to know for sure if the filters are truly Constant Q is to inspect their frequencyresponse curves. Sabine FBX Filters are true Constant Q filters.FBX Feedback Exterminator® Theory & PracticeSabine Constant Q Filters

Althoughthe filters are very transparent, why add filtering if you can avoid it? Andwhy divide your processing power among multiple signals?Placing the filtering and other signal processing in the input signal pathis a concept called Targeted Input Processing. It means each micro-phone so equipped will have customized, unique signal processingapplied — and no unnecessary processing.With FBX technology, your microphone will finally sound loud enough,everyone in the audience will understand each word, and feedback willbe far less likely to make an unwelcome and unexpected visit—andyou’ll be comfortable knowing that protection is extended to anywherea wireless microphone might be taken.14.3.2. FBX Fixed & Dynamic FiltersFBX filters come in two flavors, fixed and dynamic. Both operate auto-matically. There is no audible difference between fixed and dynamic fil-ters in terms of sonic purity; the difference arises in their application.14.3.2.1. Fixed FBX FiltersOnce they set automatically (see Section 7 for information on set-ting filters), fixed FBX filters will NOT change frequency. You canthink of fixed filters as cures for problem frequencies (the “first-to-feedback” frequencies encountered during normal system operation),common to most locations in the room.14.3.2.2. Dynamic FBX FiltersDynamic FBX filters also set automatically, but can change frequency,on a rotating basis, as the need arises. To help distinguish dynamicfrom fixed filters, consider the example of a speaker using a wirelesslavalier microphone, who walks under a ceiling speaker for the firsttime. In so doing, he enters a location-specific feedback zone, whereit’s possible that a problem frequency may have escaped detectionand notching by a fixed filter. If all fixed filters have been deployed, adynamic filter will be set automatically as soon as feedback ap-pears, solving the problem. Great! But what happens when thespeaker then moves away from the ceiling speaker, and close to afloor monitor? Feedback from the ceiling speaker is no longer aproblem, but a new frequency starts to squeal. If all fixed and dy-namic FBX filters are already set, a dynamic filter will change, toadjust to the new location. An FBX dynamic filter thus stands guardif new problem feedback arises after all available filters have beenset, providing a deeper and more flexible level of protection againstthe dreaded surprise of feedback.Other than the ability to change frequency, a dynamic filter is equiva-lent to a fixed filter.14.3.2.3. Balancing Fixed & Dynamic FiltersEach channel of your SWM7000 wireless receiver offers a total of 10FBX filters (combined fixed and dynamic), which can be used asneeded to exterminate feedback. After years of experience and ex-perimentation, Sabine has settled upon a default balance of 7 fixedand 3 dynamic filters, set at the factory. This default condition canbe changed to 8 fixed and 2 dynamic, by changing a DIP switch onthe back of your receiver (see Appendix D FBX Configuration DIPSwitch), or to any configuration using the Remote Control software(see Section 13).FBX Feedback Exterminator® Theory & Practice
50Sabine 2.4 GHz Smart Spectrum Wireless (BETA)If you follow setup instructions for setting FBX filters (see Section 7),your receiver will automatically exit SETUP mode (enter READYstatus) after all fixed filters, and the first dynamic filter, have set. Inthe default condition, this means you will have set eight filters (sevenfixed and one dynamic), with two dynamic filters still unset andremaining on standby alert. If you wish to set fewer filters, press theREADY button before SETUP automatically exits, after you haveset enough filters to safely achieve your desired gain level. In thatcase, in the factory default condition, you will reserve three unsetdynamic filters for standby.14.4.3. FBX Filter WidthSabine’s experience and testing with filters and sound quality along ledus to decide upon a default FBX filter width of .10 (one-tenth) octave asthe optimal notch width, able to eliminate feedback without affectingmusic programs. If, with all filters properly set, feedback is still aproblem, FBX filters may be set to .20 (one-fifth) octave width. Thiswider filter setting will help to better eliminate feedback trouble areas,but may also affect music programs slightly. Therefore, the wider set-ting is generally considered to be appropriate where speech (less de-manding than music) is the primary application of the Sabine Wirelesssystem. You can globally change FBX filter width by repositioning arear panel DIP switch, to change from .10 to .20 octave (see AppendixQQQ FBX Configuration DIP Switch), or by adjusting filter width usingthe True MobilityTM Remote Software (which allows a range of widthsfrom .01 to 1.0 octave). You may also mix filter widths, either by ad-justing individual filter widths using the Remote Software, or by chang-ing the DIP switch position during setup. The width of any set filter willalways be determined by the position of the switch at the time the filteris created.14.4.4. Who Benefits from FBX?Virtually every sound system will be improved with the Sabine TrueMobility™ Wireless System. Singers and speakers who do not havesound technicians can now increase their monitor or house systemvolume so they can hear themselves clearly and with full fidelity, with-out worrying if their microphones will suddenly squeal if they move tothe wrong place.Auditoriums and churches of all sizes will enjoy reliable feedback con-trol. Hotels and conference centers around the world can offer meetingrooms with microphones that won’t howl during programs. The SabineTrue Mobility™ Wireless System can be installed in theaters, schools,sports arenas, courtrooms, teleconferencing, intercoms or interactiveremote classrooms — anywhere one or multiple microphones are used.FBX Feedback Exterminator® Theory & Practice

52Sabine 2.4 GHz Smart Spectrum Wireless (BETA)15.3. Common Sources of RF InterferenceSince Marconi and others pioneered the first radio broadcasts, the ra-dio spectrum has become increasingly crowded with a huge diversityand variety of RF sources. The strength, frequency, location, and tim-ing cycles of these RF sources create a shifting pattern of interferingand overlapping frequencies and coverage patterns, which can renderthe use of radio microphones a difficult and unpredictable business. The typical sources of interference for conventional wireless mics canbe high-powered broadcasters such as radio stations and TV transmit-ters, or other short-range wireless devices, including multiple radiomicrophones operating at the same location (either by design, or bycoincidence), that operate in proximate (or harmonically related) band-widths. Less commonly, interference may arise from spurious outputsemitted by electronic equipment (notably computers, printers, or simi-lar devices with digital clocks), faulty electrical equipment, neon signs,dimmers and lighting controllers, and so forth.UHF and VHF mics are especially vulnerable because they share theRF spectrum with the very high-powered transmitters for television. Thecoming conversion to digital and high-definition broadcast will increasethe problems for UHF and VHF.The 2.4 to 2.4835 GHz frequency band is not only well above the funda-mental (nominal) transmission frequencies of such strong analog anddigital broadcasts, but also high enough to escape interference prob-lems occurring at the strong first harmonic of even the highest digitaltelevision broadcast. The band is approved worldwide for a variety ofuses, including such diverse transmitters as baby monitors, garagedoor openers, wireless LANs, amateur satellite, cordless telephones,etc. Compared to RF broadcast sources like television and radio sta-tions, these low power devices produce very localized, short range in-terference; furthermore, many of the devices working in the 2.4 GHzrange use spread spectrum transmission and reception. Both of thesefacts mean such uses of the RF spectrum are less likely to causeinterference with, or suffer from interference from the use of, Sabine’ssystems. 15.3.1 RF sources and bandwidthsYour first step in checking for interference should be utilizing the Scanfunction in the SWM7000 Remote Control Software. See section QQQfor a complete discussion of the benefits of scanning, which will revealany potential RF sources in your location and allow you to make aninformed choice of channels to use. The scanner can scan for longperiods of time and will give you a report of RF activity over time foreach of the 70 channels available on your Smart Spectrum system.1. Microwave ovens: 2.450 - 24.60 GHz, SWM7000 channels 26through 37In the vast majority of situations, interference from microwave ov-ens will not affect performance of your SWM7000 series micro-phone systems, for several reasons. First, since barriers such aswalls work to block interference, a microwave oven will likely presenta problem only when located in fairly close proximity within thesame room as the wireless receiver (or reception antenna). Sec-ond, microwave ovens emit RF only when in use — and even then,consumer microwave ovens are actively emitting RF for only about8 msec during each AC power cycle, allowing the balance of theTips & Troubleshooting
53 Sabine 2.4 GHz Smart Spectrum Wireless (BETA)B4-SWM7000-OpGuide.pmd - 021022 - htoTips & Troubleshootingcycle (50% - 60%) for signal recovery. Consumer-quality micro-wave ovens emit RF restricted to a narrow band (2450 - 2460 MHz).This targeted band affects less than 12% of the bandwidth avail-able for operation with Sabine systems, and can be avoided bychanging RF channels for transmitters and receivers, with at worsta 12% reduction in the number of clear, available channels.Commercial quality microwave ovens present a bigger potentialproblem. They sweep over a wider band of frequencies than thelimited band affected by consumer units, and use two magnetrontubes which alternate to avoid inactivity during a power cycle. Fortunately, Sabine systems are only affected by such ovens inclose proximity to receiver antennas. That protection, plus theavailability of 70 different RF channels to choose from, makes seri-ous interference problems arising from microwaves unlikely andavoidable. 2. WLANS (wireless local area networks): QQQ – QQQ GHz,SWM7000 channels QQQ through QQQThese computer network devices allow computers to connect viawireless devices that act as both receivers and transmitters. Theselow-powered transceivers often have selectable channels and canutilize the entire 2.4 GHz band. In general Sabine microphoneswill not be affected by these WLANS because their spread spec-trum technology does not present a problem for the Smart Spec-trum system.You can, however, experience interference if the Sabine receiver iscloser than 2 meters to the WLAN device, and the Sabine trans-mitter is greater than 20 meters away from the receiver. Addition-ally, the Sabine wireless system will not interfere with the WLANunless the converse situation arises. Placing the Sabine transmit-ter closer than 2 meters to the WLAN device and placing the Sabinereceiver greater than 20 meters away could cause interference inyour WLAN from the Sabine wireless. Both these situations areeasy to avoid, and we recommend you observe these limitations.For a true picture of the RF imprint of your WLAN, perform a Scanwith the SWM7000 Remote Software.3. Cordless phones: QQQ – QQQ GHz, SWM7000 channels QQQthrough QQQThese home telephones broadcast at very low power in general willnot present any interference problems with your Sabine wireless.This is especially true if the telephone uses spread spectrum tech-nology. Again, the only potential for interference comes when thecordless phone transmitter is extremely close to the Sabine re-ceiver and the Sabine transmitter is very far away. For best resultsavoid these conditions.4. Wireless Video Cameras: QQQ - QQQ GHz, SWM7000 channelsQQQ through QQQCertain wireless video cameras (X10, for example) use the 2.4 GHzband. These devices are also very low power and will not present aproblem when using the SWM7000 system.In the event problems still arise, see Section 5 Receiver Operation formethods of optimizing clear reception and minimizing interference.

All wireless microphones haveIow-power transmitters (less than 0.05 watts output) that are unlikely to cause difficulty, especially if they are at least a few inches away.However, since a beltpack transmitter typically is placed against the body, Sabine suggests attaching it at the belt, rather than in a shirtpocket where it may be immediately adjacent to an implanted medical device. Note also that any medical-device disruption will ceasewhen the RF transmitting source is turned off. Please contact your physician or medical-device provider if you have any questions, orexperience any problems with the use of this or any other RF equipment.
