1. INTRODUCTION

Thank you very much for expressing your confidence in our products by purchasing one of our equalizers. This 2-channel high-end equalizer was designed with our experience and knowhow in filter 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 fit-andfinish quality. 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 laborintensive 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-off frequency. You can also adjust the fader range from 6 to 12 dB for each channel independently.

My friends, its been worth the effort!

Thank you very much,

Uli Behringer
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 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. 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. 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 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).
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 filled out warranty card within 14 days of the date of purchase. You may also register online at www.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.

1.2 The users manual

The users 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 www.behringer.com. For example, additional information about power amps and effects processors is found there.
The following users manual is intended to familiarize you with the units control elements, so that you can master all the functions. After having thoroughly read the users manual, store it at a safe place for future reference.
2. CONTROL ELEMENTS AND CONNECTORS

2.1 Front panel

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.
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, lets 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. 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 , 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. 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.

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 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.
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 units voltage, you must change the fuse accordingly. The correct value of the fuse needed can be found in the chapter SPECIFICATIONS.
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. The RANGE switch lets you alternate between the maximum value of lowering/increasing of individual frequencies from 12 dB to 6 dB (switch depressed). 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 dont 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.

2.2 Rear panel

Fig. 2.1: Front panel control elements of the FBQ3102 (above) and of the FBQ1502 (below) 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. 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. 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. The INPUT control is used to adjust the input signal level. You can boost/attenuate the signal level from +15 to -15 dB. 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. 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. Fig. 2.2: Control elements and important information on the rear of the FBQ3102 The POWER switch powers up your ULTRAGRAPH PRO. The POWER switch should always be in the Off 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 disconnect 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. FBQ1502s power switch is located at the front. The connection to the mains is done via a standard IEC connector. A matching cable is included. 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 highervalue fuse. SERIAL NUMBER. Please take a few minutes and send to us a completely filled out warranty card within 14 days of the original date of purchase. Otherwise, warranty claims may be rendered invalid. Or fill out the warranty information online at www.behringer.com.
Fig. 2.3: Connectors at the rear of the FBQ3102 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 1/4" TRS and XLR connectors. OUTPUT. These are the audio outputs. The 1/4" connectors and their respective XLR connectors are wired in parallel. 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 amplifiers input to this connector. Use the X-OVER FREQ control to select the desired crossover frequency for the subwoofer. The bandwidth limitation enacted through the highpass filter (LOW CUT) also affects the frequency response of the subwoofer output. Fig. 2.4: FBQ6200 control elements The limiter display informs you about the amount of gain reduction perfomed by the limiter. 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 Additional FBQ6200 control elements

2.3.1 Limiter

One of the FBQ6200s 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.

2.3.2 Noise generator

By using the built-in noise generator, you can create the socalled pink noise that can be used to adjust your P.A. system to specific acoustic characteristics of various venues. 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. Read off the noise generators signal level on the LED display. 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 reproduction.

Please take into consideration that when you increase the presence 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. The ULTRAGRAPH PRO FBQ6200 features a built-in limiter for each channel. Use the LIMITER switch for its activation.
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).
3.1 Master equalizer in sound reinforcement systems
This diagram shows a typical set-up with the ULTRAGRAPHPRO models (see fig. 3.1). To achieve optimal results, you should pay attention to several issues: Before you start correcting the frequency response of a setup, it is advisable to first 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 first 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-XPRO 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 ULTRAGRAPHPRO. Disturbing noise (e. g. mains-induced hum) as well as narrowband resonances should first be tackled by using the ULTRAGRAPHPRO (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 its time to start finetuning 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.

2.3.3 Subwoofer section

The LED display indicates the signal level present at the SUB OUT connector. The signal level present at the subwoofer output connector can be adjusted by using the LEVEL control. 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.

3. APPLICATION EXAMPLES

The flexible concept of the ULTRAGRAPH PRO models, with the diverse possibilities in sound processing, open up an entire range of application possibilities for you.
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.
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.
Fig. 3.1: The ULTRAGRAPH PRO FBQ6200 as master equalizer
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. 2. 3. this protects your hearing, there are fewer feedback problems, and it is easier to create a good FOH 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 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. 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. Leave all other faders in the middle position as long as no need for frequency correction occurs (e.g. measuring with a realtime analyzer). Set the desired stage volume, and you will have a tremendous amount of headroom available to you, without creating audible feedback.
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 filter and set it up in such a way that extremely deep feedback completely disappears, creating a more transparent monitor sound.
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 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.

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 ULTRAGRAPHPRO on hightemperature devices such as power amplifiers etc. to avoid overheating. For rack mounting, please use M6 metal nuts and bolts. Fig. 4.3: 1/4" TRS connector

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. The ULTRAGRAPH PRO is installed with electronically servobalanced 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.
