1. Introduction  
1.1 Before you get started  
FBQ Feedback Detection System  
1.1.1 Shipment  
The FBQ Feedback Detection System is one of the most outstanding characteristcs The ULTRAGRAPH PRO was carefully packed at the factory to assure secure  
of our graphic equalizers. This ingenious circuitry lets you immediately recognize transport. Should the condition of the cardboard box suggest that damage may  
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.  
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.  
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.  
1.1.2 Initial operation  
Please make sure the unit is provided with sufficient ventilation, and never place  
the ULTRAGRAPH PRO on top of an amplifier or in the vicinity of a heater to avoid  
the risk of overheating.  
All three models feature a dedicated subwoofer output with adjustable cut-off  
frequency. You can also adjust the fader range from 6 to 12 dB for each  
channel independently.  
Before plugging the unit into a power socket, please make sure you  
have selected the correct voltage:  
The FBQ1502 requires just one rack space, yet it offers you tons of effective  
methods for adjusting the sound characteristics, and is ultra-compact and  
extremely simple to operate.  
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!  
The FBQ3102 features 31 frequency bands per channel as well as adjustable  
high-pass and low-pass filters. These filters 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.  
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”.  
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 certified  
management system.  
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.  
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

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.  
Balanced inputs and outputs  
The BEHRINGER ULTRAGRAPH PRO models feature electronic servo-balanced  
inputs and outputs. The servo function performs automatically, recognizing when  
unbalanced signals are connected and internally converts the nominal signal  
level so that no signal level difference between input and output signals occurs  
(6 dB correction).  
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 specific  
topics not covered in this manual, please visit our website at behringer.com.  
For example, additional information about power amps and effects processors is  
found there.  
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.

2. Control Elements and Connectors (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.  
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 find 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.  
(3) When you press the FBQ switch, the FBQ feedback detection system  
is activated. The frequency (or frequencies) 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.  
(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 (2), the display shows either the input or the output signal  
(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.  
(5) The INPUT control is used to adjust the input signal level. You can  
boost/attenuate the signal level from +15 to -15 dB.  
Attention: extreme frequency boosts in connection with a high input  
signal level may lead to overdriving your equipment. Should this  
occur, it is necessary to reduce the input signal level by using the  
INPUT control.  
(6) The LOW CUT control is used to adjust the lower cut-off frequency of your  
ULTRAGRAPH PRO. The high-pass filter (18 dB/oct.) covers the range between  
10 and 400 Hz, whereby the filter lets the signal pass through unprocessed,  
when the control is in the 10 Hz position.  
The FBQ1502 features a switchable high-pass filter (LOW CUT) instead of a  
low cut control, and its cut-off frequency is 25 Hz.  
(7) The HIGH CUT control is used to adjust the upper cut-off frequency of your  
ULTRAGRAPH PRO. The low-pass filter (18 dB/oct.) covers the range between  
2.5 and 30 kHz, whereby the filter 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.

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

of multiple frequency bands, the overall signal level increases  
substantially 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.

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.  
(22) Read off the noise generator’s signal level on the LED display.  
(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.  
(18) (20) (19)  
(21) (22)  
(23)  
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 reproduction.  
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  
(24) The LED display indicates the signal level present at the SUB OUT connector.  
(25) The signal level present at the subwoofer output connector can be adjusted  
by using the LEVEL control.  
(26) To activate the subwoofer output, please depress the SUBWOOFER switch.  
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 try to position the subwoofer in a central location between  
the two main speakers. This way, you minimize run-time differences and the  
sound quality deterioration associated with them.  
(26) (25)  
(24)  
Fig. 2.4: FBQ6200 control elements  
(19) The limiter display informs you about the amount of gain reduction  
perfomed by the limiter.  
(20) The limiter confines 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 specific 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.

issue to be overcome in your setup. Loudspeaker location is also very important.  
No equalizer in this world can significantly correct the dull sound created through  
reflexion 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 first be tackled by using the ULTRAGRAPH PRO (also see ch. 3.2.1).  
You should definitely perform all these adjustments before modifying the  
overall sound.  
Now you have a basic setup and now it’s time to start fine-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 off in the bass segment of the  
signal because otherwise 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 different 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.  
Fig. 3.1: The ULTRAGRAPH PRO FBQ6200 as master equalizer  
An equalizer is no solution for bad equipment, but it is an extremely useful and  
effective sound tool for musical fine-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  
3.2.1 Priming a monitor system  
When using your ULTRAGRAPH PRO in the monitor path, the same applies as  
when using it as described in section 3.1.  
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.  
Basically, the stage volume should be as low as possible because:  
1. this protects your hearing,  
Now, activate the FBQ feedback detection system by pressing the FBQ switch (3).  
The slide control LEDs (9)will turn dark. Then, increase the amplification on your  
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.  
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.  
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-frequency feedback.  
Your monitors have reached their maximum volume.  
Extremely deep frequencies are usually completely removed to avoid creating a  
“queasy” feedback stage sound. To this end, use the low-cut filter and set it up in  
such a way that extremely deep feedback completely disappears, creating a more  
transparent monitor sound.  
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:  
VP1220F  
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:  
Outputs  
left & right  
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 find a fitting ratio between the intensity of these  
various frequency ranges in order to achieve a homegenous sound.

3.4 Special sound effects  
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 filter instruments so that they fit in an existing mix.  
The tables on the separate add-on sheet give you an idea of specific frequencies  
and their acoustic significance, and suggest some possible uses for your  
ULTRAGRAPH PRO.

4. Installation  
4.1 Rack mounting  
The FBQ1502 requires one height unit (1 HU) for mounting in a 19" rack,  
the FBQ3102 two height units, and the FBQ6200 three height units. Please allow  
at least an additional 4" of space for the connectors on the back panel.  
Be sure that there is enough space around the unit for cooling and please do  
not place your ULTRAGRAPH PRO on high-temperature devices such as power  
amplifiers etc. to avoid overheating.  
For rack mounting, please use M6 metal nuts and bolts.  
4.2 Audio connections  
You will need many different cables for the various applications. The following  
illustrations show how these cables should be laid out. Please use exclusively  
high-grade cabels.  
Fig. 4.2: ¼" TS connector  
The ULTRAGRAPH PRO is installed with electronically servo-balanced inputs and  
outputs to avoid hum noise problems.  
You can, of course, also connect unbalanced devices to the balanced inputs/  
outputs. Either use mono plugs, or connect the ring and sleeve of stereo plugs  
(bridge pin 1 and pin 3 when using XLR connectors).  
Please ensure that only qualified personnel install and operate the  
ULTRAGRAPH PRO. During installation and operation the user must  
have sufficient electrical contact to earth. Electrostatic charges might  
affect the operation of the unit.
