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.

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!

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

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.

◊ 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.

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 (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.

◊ 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) (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.

(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.
