Thank you

Thank you very much for ex pressing your con  dence in our products by
purchasing one of our equalizers. This 2-channel high-end equalizer was
designed with our experience and know-how in lter technology spanning
many years. Our analog and digital equalizers are used the world over in various
reputable studios, P.A. systems and radio and TV stations. Just like with the
rest of our product line, when we started designing the new ULTRAGRAPH PRO
models, we had put forth uncompromizing demands in terms of controls, sound,
technical data and t-and-nish qualit y.

1. Introduction

FBQ Feedback Detection System

The FBQ Feedback Detection System is one of the most outstanding characteristcs
of our graphic equalizers. This ingenious circuitry lets you immediately recognize
and eliminate feedback frequencies. The FBQ Feedback Detection System
uses the LEDs in the frequency band faders to indicate the critical frequencies.
Thisway, what once used to be a labor-intensive search for feedback frequencies
is now an activity that even a child could master.

In normal operation, the fader LEDs indicate frequency ranges with the highest
energy levels, therefore replacing a separate audio analyzer. If you keep an eye
on the LEDs while you play back your music (or during the sound check before
a show), you can easily identify those frequency ranges showing the highest
energy levels. Similarly, increased signal levels on individual frequency bands
indicate a higher likelihood that feedback may occur.

All three models feature a dedicated subwoofer output with adjustable cut-o
frequency. You can also adjust the fader range from ±6 to ±12 dB for each
channel independently.

The FBQ1502 requires just one rack space, yet it oers you tons of eective
methods for adjusting the sound characteristics, and is ultra-compact and
extremely simple to operate.

The FBQ3102 features 31 frequency bands per channel as well as adjustable
high-pass and low-pass lters. These lters further augment the adjustability
options available to you.

With its integrated limiters, noise generator and the adjustable subwoofer
output with signal level display and its 62 lighted 45 mm faders, the FBQ6200 is
our top model in this category.

Future-oriented BEHRINGER technology

To assure the highest possible degree of usability, all our equipment is
manufactured adhering to the highest quality standards in the audio
industry. Your equalizer has been manufactured under ISO9000 certied
managementsystem.

Relay-controlled hard bypass

The so-called hard bypass relays were integrated into the development concept
of the FBQ6200 and the FBQ3102. These relays assure that your equalizer is
automatically switched into bypass mode in the event of loss of power or faulty
power delivery. These fail-safe relays also produce a slight delay during powering
up in order to avoid dangerous switch-on thumps.

Balanced inputs and outputs

1.1 Before you get started

1.1.1 Shipment

The ULTRAGRAPH PRO was carefully packed at the factory to assure secure
transport. Should the condition of the cardboard box suggest that damage may
have taken place, please inspect the unit immediately and look for physical
indications of damage.

◊ Damaged units should NEVER be sent directly to us. Please inform the

dealer from whom you acquired the unit immediately as well as the
transportation company from which you took delivery of the unit.
Otherwise, all claims for replacement/repair may be rendered invalid.

1.1.2 Initial operation

Please make sure the unit is provided with sucient ventilation, and never place
the ULTRAGRAPH PRO on top of an amplier or in the vicinity of a heater to avoid
the risk of overheating.

◊ Before plugging the unit into a power socket, please make sure you

have selected the correct voltage:

The fuse compartment near the power plug socket contains three triangular
markings. Two of these triangles are opposite one another. The voltage
indicated adjacent to these markings is the voltage to which your unit has
been set up, andcan be altered by rotating the fuse compartment by 180°.

ATTENTION: Thisdoes not apply to export models that were for example
manufactured only for use with 120 V!

◊ If you alter the unit’s voltage, you must change the fuse accordingly.

The correct value of the fuse needed can be found in the
chapter “Specifications”.

◊ Faulty fuses must be replaced with fuses of appropriate rating without

exception! The correct value of the fuse needed can be found in the
chapter “Specifications”.

Power is delivered via the cable provided with the unit. All requiered safety
precautions have been adhered to.

◊ Please make sure that the unit is grounded at all times. For your own

protection, you should never tamper with the grounding of the cable or
the unit itself.

1.1.3 Warranty

Please take a few minutes and send us the completely lled out warranty card
within 14 days of the date of purchase. You may also register online at behringer.
com. The serial number needed for the registration is located on the rear of the
unit. Failure to register your product may void future warranty claims.

The BEHRINGER ULTRAGRAPH PRO models feature electronic servo-balanced
inputs and outputs. The servo func tion performs automatically, recognizingwhen
unbalanced signals are connected and internally converts the nominal signal
level so that no signal level dierence between input and output signals occurs
(6 dB correction).

◊ The following user’s manual is intended to familiarize you with the

unit’s control elements, so that you can master all the functions.
After having thoroughly read the user’s manual, store it at a safe place
for future reference.

1.2 The user’s manual

The user’s manual is designed to give you both an overview of the control
elements, as well as detailed information on how to use them. In order to help
you understand the links between the controls, we have arranged them in groups
according to their function. Should you need detailed information about specic
topics not covered in this manual, please visit our website at behringer.com.
Forexample, additional information about power amps and eects processors is
found there.

2. Control Elements and Connectors

2.1 Front panel

In this chapter we will describe various control elements of your equalizer.
Allcontrols and connectors are explained in detail, and you will also nd useful
hints on how to best use them. Since the three equalizers in the FBQ series
are fairly similar, let’s start with the control elements of the FBQ1502 and
the FBQ3102 that are similar to the control elements found on the FBQ6200.
TheFBQ6200 additionally features extra control elements that will be explained
in detail later on.

(1) The INPUT/OUTPUT LEVEL METER lets you keep an eye on the signal level

in order to avoid distortion. Depending on the position of the I/O METER
IN/OUT switch
(switchdepressed) level. When the signal level reaches roughly +18 dB,
thatis, 3dBbelow clipping starts to occur, the red CLIP LED lights up.

The level meter on the FBQ1502 displays only the output signal level.

◊ Attention: extreme frequency boosts in connec tion with a high input

signal level may lead to over driving your equipment. Should this
occur, it is necessary to reduce the input signal level by using the
INPUT control.

(2), the display shows either the input or the output signal

(2) (1) (3)

(2) The I/O METER IN/OUT switch lets you alternate between displaying the

input and the output signal level. When the switch is depressed, the output
signal level is shown. The FBQ1502 does not feature this switch.

(3) When you press the FBQ switch, the FBQ feedback detection system

is activated. The frequency (or frequen cies) that evoke feedback is/are
indicated by means of a lighted fader LED. All other LEDs are toned down.
Now, simply lower the respective frequency range somewhat until you
eliminate the feedback and the LED no longer lights up.

(4) The AUDIO IN/OUT switch is used to enable or disable the entire equalizer

section. The FBQ1502 does this electronically, while the FBQ3102 and the
FBQ6200 feature a relay-driven hard bypass function. As long as the switch
is not depressed or while the equalizer is not powered up, the inputs and the
outputs are directly connected to one another. The AUDIO IN/OUT switch is
used to alternate between A and B, i.e. to compare the original unprocessed
signal with the processed signal.

(5) The INPUT control is used to adjust the input signal level. You can

boost/attenuate the signal level from +15 to -15 dB.

(6) The LOW CUT control is used to adjust the lower cut-o frequency of your

ULTRAGRAPH PRO. The high-pass lter (18 dB/oct.) covers the range between
10 and 400 Hz, whereby the lter lets the signal pass through unprocessed,
when the control is in the 10 Hz position.

The FBQ1502 features a switchable high-pass lter (LOW CUT) instead of a
low cut control, and its cut-o frequency is 25 Hz.

Fig. 2.1: Front panel cont rol elements of th e FBQ3102 (above) and o f the FBQ1502 (below)

(6)

(8) (9)

(7) The HIGH CUT control is used to adjust the upper cut-o frequency of your

ULTRAGRAPH PRO. The low-pass lter (18 dB/oct.) covers the range between

2.5 and 30 kHz, whereby the lter lets the signal pass through unprocessed
when the control is in the 30 kHz position.

◊ Use the high-pass and low-pass filters to define the frequency range

you wish to process. This provides you with an efficient way to limit the
bandwidth you work with.

(8) The RANGE switch lets you alternate between the maximum value

of lowering/increasing of individual frequencies from 12 dB to 6 dB
(switchdepressed).

(9) These are the 31 SLIDING CONTROLS (FBQ1502: 15 sliding controls per

channel) for individual frequency bands. When in “0” position, the particular
frequency range is not processed at all. To boost a frequency range, pull the
sliding control upward; to attenuate, pull the sliding control downward.

◊ To emphasize a frequency range, you don’t necessarily have to move

its respective sliding control upward; try lowering surrounding
frequency ranges instead. This way, you avoid causing the next piece of
equipment in your sound path to overdrive. You also preserve valuable
dynamic reserve (“headroom”).

Sliding controls feature LEDs that indicate the signal level of their particular
frequency ranges through their varying illumination intensity: what better
way to show critical frequencies that evoke feedback. How to best use
your ULTRAGRAPH PRO to detect these critical frequencies is described in
chapter3.2.1.

(10) The POWER switch powers up your ULTRAGRAPH PRO. The POWER switch

should always be in the “O” position when you are about to connect your
FBQ to the mains.

To disconnect the unit from the mains, pull out the main cord plug.
Wheninstalling the product, ensure that the plug is easily accessible.
Ifmounting in a rack, ensure that the mains can be easily disconnected
by a plug or by an all-pole disconnec t switch on or near the rack.

◊ Please keep in mind: The POWER switch does not entirely separate the

unit from the mains. Please disconnect the power cord from the mains
if you will not be using your FBQ for longer periods of time.

FBQ1502’s power switch is located at the front.

(11) The connection to the mains is done via a standard IEC connector.

Amatching cable is included.

(12) FUSE COMPARTMENT / VOLTAGE SELECTION. Before connecting the unit

to a power outlet, please make sure that the selected voltage matches your
local voltage. When replacing fuses, please make sure that you always use
fuses of the same type. Some units allow for switching between 230 V
and 120 V. Please note: when connecting a unit intended for the European
market to a 120 V power outlet, you must also replace the factory fuse with a
higher-value fuse.

(13) SERIAL NUMBER. Please take a few minutes and send to us a completely

lled out warranty card within 14 days of the original date of purchase.
Otherwise, warranty claims may be rendered invalid. Or ll out the warranty
information online at behringer.com.

Fig. 2.3: Connec tors at the rear o f the FBQ3102

(14) INPUT. These are the audio inputs of the FBQ3102. All three equalizers in the

series feature the same input and output connectors in the form of balanced
¼" TRS and XLR connectors.

(15) OUTPUT. These are the audio outputs. The ¼" connectors and their

respective XLR connectors are wired in parallel.

(16) SUB OUT. This balanced XLR connector provides the output signal for your

subwoofer. A summed up mono signal for the subwoofer is provided here.
Please connect the subwoofer amplier’s input to this connector.

(17) Use the X-OVER FREQ control to select the desired crossover frequency for

thesubwoofer.

◊ The bandwidth limitation enacted through the high-pass

filter (LOW CUT) also affects the frequency response of the
subwoofer output.

2.3 Additional FBQ6200 control elements

2.3.1 Limiter

One of the FBQ6200’s outstanding features is its integrated limiter.

A limiter is a device that protects your loudspeakers and other equipment
connected to your FBQ6200 (or your recordings) from overdriving and the signal
distortion associated.

◊ Please take into consideration that when you increase the presence

of multiple frequency bands, the overall signal level increases
subs tantially as well. The limiter will process very quickly in such
situations. This can be avoided by performing signal corrections by
lowering certain frequency ranges instead of increasing others.

To produce creative sound effects, you can also purposely “force” the
peak limiter into action.

8 ULTRAGRAPH PRO FBQ6200/FBQ3102/FBQ1502 User Manual

(18) The ULTRAGRAPH PRO FBQ6200 features a built-in limiter for each channel.

Use the LIMITER switch for its activation.

(19) (21)

(22)(20)(18)

(23)

(22) Read o the noise generator ’s signal level on the LED disp lay.

(23) Use the NOISE LEVEL control to adjust the volume of the pink noise

yougenerate.

Room resonance and sound transfer characteristics of the P.A. system cause some
frequencies to be more prominently present while other frequencies are less
present. Pink noise is a neutral signal that can be played back via the P.A. system
in order to measure these sound characteristics.

Such a measurement of the frequency response by using a special microphone
in conjunction with a real-time analyzer (a real-time analyzer is for example
integrated into the BEHRINGER ULTRACURVE PRO DEQ2496) delivers the basis
for setting up the equalizer. More pronounced frequencies are lowered,
andthose frequencies that are not so prominently featured are increased,
thusapproximately achieving linear reproduc tion.

◊ Try to orient yourself on a frequency whose signal level lies in the 0 dB

to -3 dB range in order to avoid overdriving the equipment connected
(e.g. power amplifier, crossover).

2.3.3 Subwoofer section

(19) The limiter display informs you about the amount of gain reduc tion

perfomed by the limiter.

(20) The limiter connes the signal to an adjustable signal level. Use the

THRESHOLD control to adjust the threshold value of the limiter from -6to
+22 dB. When the control is in the “-6 dB” setting, the gain reduction is
very pronounced; the more you turn the control toward “+22 dB”, the gain
reduction is lower. When the threshold control is in its right-most position,
the limiter is not applied.

2.3.2 Noise generator

By using the built-in noise generator, you can create the so-called “pink noise”
that can be used to adjust your P.A. system to specic acoustic characteristics of
various venues.

(21) Activate the pink noise generator by using the PINK NOISE switch.

Thebuilt-in switch illumination blinks red when the pink noise generator
isactivated.

In general, the location of a subwoofer is not critical, since the source of
deeper freqencies is not easily determined. However, to achieve optimal sound
resolution, you should tr y to position the subwoofer in a central location between
the two main speakers. This way, you minimize run-time dierences and the
sound quality deterioration associated with them.

3.1 Master equalizer in sound
reinforcementsystems

This diagram shows a typical set-up with the ULTRAGRAPHPRO models
(seeg.3.1).

To achieve optimal results, you should pay attention to several issues:

Before you star t correcting the frequency response of a setup, it is advisable to
rst let the music and other sound sources run “uncorrected”, as this is something
that has proven itself in practice. If distortion occurs, such overdriving is the rst
issue to be overcome in your setup. Loudspeaker location is also very impor tant.
No equalizer in this world can signicantly correct the dull sound created through
reexion of wall structures and ceilings. Often, very dramatic improvements can
be made by simply placing and aligning speakers correctly.

If you are using an active multi-way system you should take some run-time and
phase correction measures before you work with the ULTRAGRAPH PRO (our
crossover network SUPER-XPRO CX3400 provides all the necessary tools with
its variable split frequencies, phase reverse switches and electronic run-time
correction facility). Onlyafter making these preliminary adjustments should you
start implementing them on your ULTRAGRAPHPRO.

Disturbing noise (e. g. mains-induced hum) as well as narrow-band resonances
should rst be tackled by using the ULTRAGRAPHPRO (also see ch. 3.2.1).
Youshould denitely perform all these adjustments before modifying the
overallsound.

Now you have a basic setup and now it’s time to start ne-tuning your sound.

Some ground rules:

A linear response curve is not ideal for every application. For example,
whendealing with the spoken word, intelligibility is what is most important.
Therefore,thetransmission curve should drop o in the bass segment of the
signal because other wise only interference is transmitted.

In general, extremely low and high frequencies are transmitted with much
lower amplitudes. There is no sense in “forcing” a small full-range speaker to
reproduce frequencies below 50 Hz; apart from a need for higher power reserves,
speakerdamage will be the most likely result.

◊ Always respect the physical limitations of your system.

After setting up your system as precisely as possible to the desired transmission
curve, walk around the venue in order to get an impression of what your signal
sounds like in dierent locations. Do not forget to take regular breaks while you
do this, and also try to use various program sources to truly develop a feeling for
what your system really sounds like and how the venue carries the sound.

◊ Setting up your equalizer well takes a lot of time and patience! If you

notice that only extreme settings on your equalizer create a usable
frequency response, this is probably a good indication that a cardinal
mistake may have been committed elsewhere in the P.A. system or
room acoustics.

An equalizer is no solution for bad equipment, but it is an extremely useful and
eective sound tool for musical ne-tuning. Fine-tuning often leads to amazing
improvements in acoustic penetration and in the overall sound quality of your
entire setup.

3.2 Equalizer in the monitor path

When using your ULTRAGRAPH PRO in the monitor path, the same applies as
when using it as described in section 3.1.

Basically, the stage volume should be as low as possible because:

1. this protects your hearing,

2. there are fewer feedback problems, and

3. it is easier to create a good FOH sound.

Often, monitor volume level is increased during a concert. Use intermissions in
the program to lower all monitor paths roughly 3 dB. The musicians will hardly
notice this reduction because their hearing can recover somewhat during an
intermission. This way you can achieve valuable headroom for possible use later
in the program.

Extremely deep frequencies are usually completely removed to avoid creating a
“queasy” feedback stage sound. To this end, use the low-cut lter and set it up in
such a way that extremely deep feedback completely disappears, creating a more
transparent monitor sound.

3. 2.1 Priming a monitor system

Priming describes the process of detecting and supressing feedback frequencies.
After placing and leveling your mics and monitors (incl. power amps), you should
crank up the aux send controls of your mixer.

Now, activate the FBQ feedback detection system by pressing the FBQ switch
The slide control LEDs

(9) will turn dark. Then, increase the amplication on your

(3).

mixer by using the aux send master control until you notice feedback starting to
occur. Feedback frequencies will now be easily visible through intensive lighting
of the relevant LEDs.

Pull down the slide controls whose LEDs are lit until the feedback subsides.
Repeat this procedure to weed out other possible feedback frequencies.
Afterhaving adjusted all critical frequencies, when you crank up the aux send
master control, you will be able to hear only the initial multi-frequenc y feedback.
Your monitors have reached their maximum volume.

Leave all other faders in the middle position as long as no need for frequency
correction occurs (e.g. measuring with a real-time analyzer). Set the desired
stage volume, and you will have a tremendous amount of headroom available
toyou, without creating audible feedback.

3.3 Using the ULTRAGRAPH PRO in the studio

Additional applications await the ULTRAGRAPH PRO models in the studio.
Nolimits stand in the way of your imagination. Here are just a few examples
ofpossible uses:

EQing your studio monitors:

You can conduct a graphic equalization of your monitors. Besides, you can supress
narrow-band room resonance. An analyzer, for example the analyzer integrated
into our digital equalizer ULTRACURVE PRO DEQ2496, can help you when you are
looking for room resonance and a linear frequency response.

General sound processing:

Equalizers can be used to process both single-channel and master signals.
Toprocess single-channel signals, you should connect the ULTRAGRAPHPRO
via the channel inserts on your mixer. To control several signals with your
ULTRAGRAPH PRO, use either subgroup or main mix inserts. Nowadays,
theoverall sound of a mix is often “tweaked” with equalizers. Often, a mix is not
uniform, that is, frequency ranges are either too prominent or not prominent at
all. A graphic equalizer lets you nd a tting ratio between the intensity of these
various frequency ranges in order to achieve a homegenous sound.

3.4 Special sound eects

In recording studios as well as stage or radio plays, the ULTRAGRAPH PRO will be
your valuable sound tool for modifying the sound of voices (e.g. telephone voice)
or to lter instruments so that they t in an existing mix.

The tables on the separate add-on sheet give you an idea of specic frequencies
and their acoustic signicance, and suggest some possible uses for your
ULTRAGRAPH PRO.
