FBX Feedback Exterminator® Theory & Practice
14. FEEDBACK CONTROL THEORY & PRACTICE
14.1. Introduction to FBX®
WHY FBX? Feedback is certainly the most pervasive challenge to the audio industry. The potential
appearance of sudden, loud, out-of-control feedback
is every sound engineer’s and musician’s nightmare.
Unlike more subtle audio quality problems or shortcomings, feedback is embarrassingly obvious — it
disturbs the performer, the audience, and the technician, and can damage equipment and just generally
ruin your day.
Feedback is a potential problem in any amplified sound
system that places a microphone or pickup in proximity to a loudspeaker. Poor acoustical conditions or
misguided use by unsophisticated sound system operators only aggravate the situation. To make matters still worse, a non-Sabine variety of wireless microphone adds yet another level of feedback danger
to the picture. Since feedback erupts whenever the
distance, location, and gain relationships between a
speaker and a microphone reach a critical combination, a mic that can move anywhere results in an
ever changing potential for feedback. A step in the
wrong direction may change a clear sound to a piercing shriek in less than a second.
This enhanced potential for feedback with a wireless
system gets worse if lavalier microphones are used.
Such microphones are usually placed farther from
the mouth than handheld or head set microphones,
thus requiring more gain. Also, the polar pattern of a
lavalier microphone is frequently omni-directional.
Thus, the likelihood of feedback increases, due to
the microphone’s increased off-axis sensitivity to the
sound emanating from the loudspeakers.
The Sabine True Mobility™ SWM7000 wireless systems solve feedback problems by precise attenuation of very narrow bands of feedback-prone frequencies. The process is automatic, simple to use, adaptable to changing acoustical conditions and relationships, powerful in its application, and has minimal
consequences to the audio fidelity of the signal. We
call this automatic filter a Feedback Exterminator®
filter, or FBX filter for short.
-10 dB cut at 500, 630, 1K, 1.25K, 1.6K & 2K Hz
If the graphic EQ really had 1/3 octave
filter widths, the frequency response curve
would vary 6 dB between sliders. This
would ruin the sound.
Graphic EQs usually use one-octave-wide
overlapping filters that provide much
smoother frequency response curves. Notice that the overlapping filters add together to cut -16 dB when the sliders are
only pulled down -10 dB.

14.2. The Advantages of FBX Filters
Before the invention of FBX, the most common device for controlling
feedback was the 31-band graphic EQ. However, an FBX filter offers
three distinct advantages over graphic filters.
1. First and most obvious is the automatic nature of FBX filters. When
feedback occurs, FBX responds more quickly than even the most
experienced engineer. Automatic FBX placement works even in the
presence of audio program material, intelligently distinguishing feedback from music or speech.
2. A second advantage is that FBX micro-filters are
precisely placed anywhere feedback occurs (with 1
Hz resolution), while graphic EQ filters are limited

removed by EQ filters.
Here’s a good place to make a very important distinction. Graphic EQ filters are typically called “1/
3-octave,” but it’s important to understand that this
term refers to the spacing of the filter centers (1/3octave apart), and not the width of the filter (usually
a full octave). Graphic filters thus overlap one another, and affect frequencies well above and below
the center point frequency, including frequencies of
adjacent bands. This makes graphic equalizers very
practical tools for shaping sound “with broad
strokes,” such as dialing in overall system EQ, but
results in destructive audio quality overkill when they
are used to eliminate feedback. A graphic equalizer
would need more than 10,000 narrow-band sliders
to be as precise and powerful as your FBX.
As an example of the power of FBX, figure 14c shows

tor®, power amp and two speakers. The system’s
gain was first raised until the FBX removed nine feedback points. Next, the FBX was replaced with a graphic EQ. The EQ
was adjusted while the system gain was raised to the same level
achieved with the FBX. The frequency response curves of each device
were then plotted and are compared in figure 14c. Note how much
more of the program (the “good audio”) is eliminated using an EQ —
whereas only feedback is eliminated using FBX filters.

FBX Feedback Exterminator® Theory & Practice
Sabine Constant Q Filters
It 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 at
the -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 (see
p.14, Figure 6a). Filters that get wider as the filter gets deeper are called Proportional Q filters (see p.14, Figure 6b). Lately, however, the
definition of Constant Q is becoming less distinct. Many equalizer manufacturers claim their equalizers have Constant Q filters, when in fact
they 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 frequency
response curves. Sabine FBX Filters are true Constant Q filters.
14.3. Parametric Filters and FBX
Of course, many savvy sound engineers, realizing the limitations of
graphic equalizers in removing problem feedback, prefer to use a different type of equalizer, called a parametric EQ, for such applications. If
you’re one such audio engineer, you’ll be comforted to know that FBX
filters share much in common with parametrics.
Compared to graphic filters, parametrics allow more precise adjustments — specifically, control of filter width, the amount of boost or cut,
and the mid-band frequency of the filter. This greater precision, however, comes at a price, as parametric filters are not nearly as intuitive or
simple to use as graphic equalizers.
Nothing, however, is easier to use than an FBX filter, which enjoys the
precision of a parametric filter, yet deploys instantly and automatically
whenever feedback is detected. Effectively, an FBX filter is a parametric
filter set to a tenth-octave width, restricted to cut-only activity, and automatic in its choice of frequency band. If you want hands-on control,
use the Sabine True MobilityTM Remote Software to change FBX filters
to parametrics, and tweak frequency, width, and depth to your liking.
14.3.1. The FBX & True MobilityTM Advantage
After inventing FBX technology and refining it for over a decade, Sabine
has brought our patented automatic feedback control to its fullest realization with the Sabine SWM7000 True MobilityTM wireless systems.
Our latest advance in maintaining the highest quality audio signal is
due to the placement of the signal processing in the input chain of the
microphone signal. Many times signal processing (compression and
equalization) is placed after the output stage of a mixer, meaning it is
applied to a combination of inputs mixed together into one output and
passed through the processor. Particularly in the case of equalization
and feedback control, one consequence of such placement is that filtering appropriate to only one microphone may be applied to all mics in
the same mix bus. In other words, unnecessary filtering may be applied to microphones that, due to variations in position and microphone
Sabine 2.4 GHz Smart Spectrum Wireless (BETA)

FBX Feedback Exterminator® Theory & Practice
characteristics, will feedback at a different set of frequencies. Although
the filters are very transparent, why add filtering if you can avoid it? And
why divide your processing power among multiple signals?
Placing the filtering and other signal processing in the input signal path
is a concept called Targeted Input Processing. It means each microphone so equipped will have customized, unique signal processing
applied — and no unnecessary processing.
With FBX technology, your microphone will finally sound loud enough,
everyone in the audience will understand each word, and feedback will
be far less likely to make an unwelcome and unexpected visit—and
you’ll be comfortable knowing that protection is extended to anywhere
a wireless microphone might be taken.
14.3.2. FBX Fixed & Dynamic Filters
FBX filters come in two flavors, fixed and dynamic. Both operate automatically. There is no audible difference between fixed and dynamic filters in terms of sonic purity; the difference arises in their application.
14.3.2.1. Fixed FBX Filters
Once they set automatically (see Section 7 for information on setting filters), fixed FBX filters will NOT change frequency. You can
think of fixed filters as cures for problem frequencies (the “first-tofeedback” frequencies encountered during normal system operation),
common to most locations in the room.
14.3.2.2. Dynamic FBX Filters
Dynamic FBX filters also set automatically, but can change frequency,
on a rotating basis, as the need arises. To help distinguish dynamic
from fixed filters, consider the example of a speaker using a wireless
lavalier microphone, who walks under a ceiling speaker for the first
time. In so doing, he enters a location-specific feedback zone, where
it’s possible that a problem frequency may have escaped detection
and notching by a fixed filter. If all fixed filters have been deployed, a
dynamic filter will be set automatically as soon as feedback appears, solving the problem. Great! But what happens when the
speaker then moves away from the ceiling speaker, and close to a
floor monitor? Feedback from the ceiling speaker is no longer a
problem, but a new frequency starts to squeal. If all fixed and dynamic FBX filters are already set, a dynamic filter will change, to
adjust to the new location. An FBX dynamic filter thus stands guard
if new problem feedback arises after all available filters have been
set, providing a deeper and more flexible level of protection against
the dreaded surprise of feedback.
Other than the ability to change frequency, a dynamic filter is equivalent to a fixed filter.
14.3.2.3. Balancing Fixed & Dynamic Filters
Each channel of your SWM7000 wireless receiver offers a total of 10
FBX filters (combined fixed and dynamic), which can be used as
needed to exterminate feedback. After years of experience and experimentation, Sabine has settled upon a default balance of 7 fixed
and 3 dynamic filters, set at the factory. This default condition can
be changed to 8 fixed and 2 dynamic, by changing a DIP switch on
the back of your receiver (see Appendix D FBX Configuration DIP
Switch), or to any configuration using the Remote Control software
(see Section 13).
49
Sabine 2.4 GHz Smart Spectrum Wireless (BETA)
B4-SWM7000-OpGuide.pmd - 021022 - hto
FBX Feedback Exterminator® Theory & Practice
If you follow setup instructions for setting FBX filters (see Section 7),
your receiver will automatically exit SETUP mode (enter READY
status) after all fixed filters, and the first dynamic filter, have set. In
the default condition, this means you will have set eight filters (seven
fixed and one dynamic), with two dynamic filters still unset and
remaining on standby alert. If you wish to set fewer filters, press the
READY button before SETUP automatically exits, after you have
set enough filters to safely achieve your desired gain level. In that
case, in the factory default condition, you will reserve three unset
dynamic filters for standby.
14.4.3. FBX Filter Width
Sabine’s experience and testing with filters and sound quality along led
us to decide upon a default FBX filter width of .10 (one-tenth) octave as
the optimal notch width, able to eliminate feedback without affecting
music programs. If, with all filters properly set, feedback is still a
problem, FBX filters may be set to .20 (one-fifth) octave width. This
wider filter setting will help to better eliminate feedback trouble areas,
but may also affect music programs slightly. Therefore, the wider setting is generally considered to be appropriate where speech (less demanding than music) is the primary application of the Sabine Wireless
system. You can globally change FBX filter width by repositioning a
rear panel DIP switch, to change from .10 to .20 octave (see Appendix
QQQ FBX Configuration DIP Switch), or by adjusting filter width using
the True MobilityTM Remote Software (which allows a range of widths
from .01 to 1.0 octave). You may also mix filter widths, either by adjusting individual filter widths using the Remote Software, or by changing the DIP switch position during setup. The width of any set filter will
always be determined by the position of the switch at the time the filter
is created.
14.4.4. Who Benefits from FBX?
Virtually every sound system will be improved with the Sabine True
Mobility™ Wireless System. Singers and speakers who do not have
sound technicians can now increase their monitor or house system
volume so they can hear themselves clearly and with full fidelity, without worrying if their microphones will suddenly squeal if they move to
the wrong place.
Auditoriums and churches of all sizes will enjoy reliable feedback control. Hotels and conference centers around the world can offer meeting
rooms with microphones that won’t howl during programs. The Sabine
True Mobility™ Wireless System can be installed in theaters, schools,
sports arenas, courtrooms, teleconferencing, intercoms or interactive
remote classrooms — anywhere one or multiple microphones are used.

Tips & Troubleshooting
15.3. Common Sources of RF Interference
Since Marconi and others pioneered the first radio broadcasts, the radio spectrum has become increasingly crowded with a huge diversity
and variety of RF sources. The strength, frequency, location, and timing cycles of these RF sources create a shifting pattern of interfering
and overlapping frequencies and coverage patterns, which can render
the use of radio microphones a difficult and unpredictable business.
The typical sources of interference for conventional wireless mics can
be high-powered broadcasters such as radio stations and TV transmitters, or other short-range wireless devices, including multiple radio
microphones operating at the same location (either by design, or by
coincidence), that operate in proximate (or harmonically related) bandwidths. Less commonly, interference may arise from spurious outputs
emitted by electronic equipment (notably computers, printers, or similar 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 the
RF spectrum with the very high-powered transmitters for television. The
coming conversion to digital and high-definition broadcast will increase
the problems for UHF and VHF.
The 2.4 to 2.4835 GHz frequency band is not only well above the fundamental (nominal) transmission frequencies of such strong analog and
digital broadcasts, but also high enough to escape interference problems occurring at the strong first harmonic of even the highest digital
television broadcast. The band is approved worldwide for a variety of
uses, including such diverse transmitters as baby monitors, garage
door openers, wireless LANs, amateur satellite, cordless telephones,
etc. Compared to RF broadcast sources like television and radio stations, these low power devices produce very localized, short range interference; furthermore, many of the devices working in the 2.4 GHz
range use spread spectrum transmission and reception. Both of these
facts mean such uses of the RF spectrum are less likely to cause
interference with, or suffer from interference from the use of, Sabine’s
systems.
15.3.1 RF sources and bandwidths
Your first step in checking for interference should be utilizing the Scan
function in the SWM7000 Remote Control Software. See section QQQ
for a complete discussion of the benefits of scanning, which will reveal
any potential RF sources in your location and allow you to make an
informed choice of channels to use. The scanner can scan for long
periods of time and will give you a report of RF activity over time for
each of the 70 channels available on your Smart Spectrum system.
1. Microwave ovens: 2.450 - 24.60 GHz, SWM7000 channels 26
through 37
In the vast majority of situations, interference from microwave ovens will not affect performance of your SWM7000 series microphone systems, for several reasons. First, since barriers such as
walls work to block interference, a microwave oven will likely present
a problem only when located in fairly close proximity within the
same room as the wireless receiver (or reception antenna). Second, microwave ovens emit RF only when in use — and even then,
consumer microwave ovens are actively emitting RF for only about
8 msec during each AC power cycle, allowing the balance of the
Sabine 2.4 GHz Smart Spectrum Wireless (BETA)
52
Tips & Troubleshooting
cycle (50% - 60%) for signal recovery. Consumer-quality microwave ovens emit RF restricted to a narrow band (2450 - 2460 MHz).
This targeted band affects less than 12% of the bandwidth available for operation with Sabine systems, and can be avoided by
changing RF channels for transmitters and receivers, with at worst
a 12% reduction in the number of clear, available channels.
Commercial quality microwave ovens present a bigger potential
problem. They sweep over a wider band of frequencies than the
limited band affected by consumer units, and use two magnetron
tubes which alternate to avoid inactivity during a power cycle.
Fortunately, Sabine systems are only affected by such ovens in
close proximity to receiver antennas. That protection, plus the
availability of 70 different RF channels to choose from, makes serious interference problems arising from microwaves unlikely and
avoidable.
2. WLANS (wireless local area networks): QQQ – QQQ GHz,
SWM7000 channels QQQ through QQQ
These computer network devices allow computers to connect via
wireless devices that act as both receivers and transmitters. These
low-powered transceivers often have selectable channels and can
utilize the entire 2.4 GHz band. In general Sabine microphones
will not be affected by these WLANS because their spread spectrum technology does not present a problem for the Smart Spectrum system.
You can, however, experience interference if the Sabine receiver is
closer than 2 meters to the WLAN device, and the Sabine transmitter is greater than 20 meters away from the receiver. Additionally, the Sabine wireless system will not interfere with the WLAN
unless the converse situation arises. Placing the Sabine transmitter closer than 2 meters to the WLAN device and placing the Sabine
receiver greater than 20 meters away could cause interference in
your WLAN from the Sabine wireless. Both these situations are
easy to avoid, and we recommend you observe these limitations.
For a true picture of the RF imprint of your WLAN, perform a Scan
with the SWM7000 Remote Software.
3. Cordless phones: QQQ – QQQ GHz, SWM7000 channels QQQ
through QQQ
These home telephones broadcast at very low power in general will
not present any interference problems with your Sabine wireless.
This is especially true if the telephone uses spread spectrum technology. Again, the only potential for interference comes when the
cordless phone transmitter is extremely close to the Sabine receiver and the Sabine transmitter is very far away. For best results
avoid these conditions.
4. Wireless Video Cameras: QQQ - QQQ GHz, SWM7000 channels
QQQ through QQQ
Certain wireless video cameras (X10, for example) use the 2.4 GHz
band. These devices are also very low power and will not present a
problem when using the SWM7000 system.
In the event problems still arise, see Section 5 Receiver Operation for
methods of optimizing clear reception and minimizing interference.

a stove or radiator.
Connect only to a power supply of the type marked on the unit
adjacent to the power entry module.
Never break off the ground pin on the power supply cord.
Power supply cords should always be handled carefully. Never
walk or place equipment on power supply cords. Periodically
check cords for cuts or signs of stress, especially at the plug and
the point where the cord exits the unit.

CAUTION - Implanted cardiac pacemakers or AICD devices:
Any source of RF (radio frequency) energy may interfere with normal functioning of the implanted device. All wireless microphones have
Iow-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 shirt
pocket where it may be immediately adjacent to an implanted medical device. Note also that any medical-device disruption will cease
when the RF transmitting source is turned off. Please contact your physician or medical-device provider if you have any questions, or
experience any problems with the use of this or any other RF equipment.
