ULTRAGRAPH PRO FBQ1502HD

Professional audio engineers have known for decades that a good EQ makes all the difference in how a performance is perceived. Although multi-band graphic equalizers have been around for a long time, they have changed very little… until now! The ULTRAGRAPH PRO FBQ1502HD takes the graphic equalizer into the realm of high-definiton audio, providing robust features and our proprietary FBQ Feedback Detection System

How Does Equalization Work?

Imagine the audio frequency range as a very wide highway with lots of “lanes”. Each of these lanes represents a specific frequency band.

• The lanes on the left side contain the really low frequency content, mainly bass, bass vocals, and the kick and tom drums
• The middle lanes make up the fundamental zone of most musical instruments and the male and female vocals
• The right-hand lanes have all the highfrequency stuff, such as snare drums, cymbals, higher pitched percussion instruments and the content that adds sizzle to the mix

Ultra-Low Noise Operation

The high-definition FBQ1502HD provides superb, ultra-low noise performance thanks to German engineering, and the use of quality components. 4580 dual operational amplifiers are employed throughout for the utmost signal integrity across the entire audio spectrum. With 15-bands of smooth and precise equalization per channel, the stereo FBQ1502HD adds the finishing professional touch to your recordings and live shows.

Built in Crossover

Speaking of special low-frequency tools, the FBQ1502HD also has a dedicated subwoofer output with an adjustable (30 - 200 Hz) cut-off frequency. Balanced XLR Outs are provided so you can connect to power amps or directly to your active subwoofers, without any additional hardware.

Ultra-Compact 9-Band Graphic Equalizer with FBQ

If we all lived in a perfect world, there would be no need for audio equalization. Sound systems would be perfect and would reproduce perfect signals in all their glorious perfection. Also, everyone in that perfect world would like the same amount of bass, midrange and high frequency, and there would be no such thing as feedback. But the world isn't perfect, is it? Even the best sound system can benefit from the use of a good EQ--like the FBQ800.

Even the best sound system can benefit from the use of a good EQ. Click to enlarge.

1/4-inch and RCA inputs and outputs.

Nine steps of graphic EQ.

How Does it Work?

Imagine the frequency range of the sound you hear as a highway, a very wide one with nine lanes. Each of these "lanes" represents a single octave of the sonic spectrum. The first four lanes, labeled 63 - 500 (Hz) contain the really low frequency sound content, mainly bass, bass vocals, and the kick and tom drums. The three lanes labeled 1 k, 2 k and 4 k (Hz), make up the fundamental zone of most musical instruments and the male and female vocals. 8 k and 16 k cover the frequency range of cymbals, snare drums and higher pitched percussion instruments. The FBQ800 allows you to control the flow of audio traffic in each of these nine lanes. When properly applied, EQ makes it possible to hear all of these frequency ranges equally, thus the term equalization.

Feedback Elimination

When a specific frequency, or range of frequencies, reaches too high a level, feedback occurs--that all-too-familiar squeal or howl you get when the mic is too close to the speaker. Basically, feedback happens when there is so much of a particular frequency that it is picked up by the mic and run through the system again. That's why feedback typically gets louder and louder the longer it's allowed to occur. Needless to say, this kind of feedback is very undesirable.

This is where the FBQ800's Feedback Detection System really works its magic. In this ingenious circuitry, LEDs on the individual faders light up when that frequency band is approaching the danger zone. All you need do is lower the illuminated slider until the LED blinks out--voilá, feedback problem solved! What once required a highly trained ear is now an activity that even a child can master.

Sonic Toolkit

That really is the best way to describe the FBQ800. With its nine frequency bands, you easily fine-tune your sound and instantly eliminate feedback. And each fader can be used to boost or cut the frequency range it controls by as much as 12 dB (and that's a lot!).

Special attention is paid to the low frequency zone. In addition to low frequency faders, the FBQ800 features a Low Cut filter for removing unwanted low frequencies such as fl oor rumble, room resonance, electrical hum, etc. This is especially handy if your system is being used for speech rather than music.

To Boost or to Cut, That is the Question

Raising and lowering specific frequency bands can improve the frequency response of any room's acoustics. For instance, if the room you're in is "bass-heavy," lowering the 63 and 125 Hz faders can help eliminate an overall "boomy" or "muddy" sound. Likewise, gently boosting the 8 and 16 k sliders can add sparkle to a somewhat "dark" mix. Are the vocals getting lost in the mix? Raising the level of the 1 k slider can help bring them out.

It's important to note that raising a single fader level is not always the best solution; it's often better to lower the bands surrounding the frequency you want to bring out, and then boost the overall volume level to achieve better headroom.

Built for Accuracy and Reliability

Speaking of headroom, FBQ800's 6-digit LED Input/Output meters and level control are provided for precise level maintenance. Longterm reliability is ensured, thanks to high-quality illuminated faders and switches, and our ultra low-noise audio operational amplifiers provide outstanding sonic performance. In addition, all Mini Series components may be stacked to create an ultracompact signal processing solution.

User questions & answers

Question:	What type of cables are required to hook this up between an amplifier and yamaha receiver? Much appreciated
Answer:	Both
Question:	Can you adjust each channel (left/right) separately
Answer:	Nope, the only things lit are the little indicator lights for power +/- 12dbs and something else.
Question:	I see many mention that they use this for helping hearing loss by using this unit with headphones. My question is how do you use this with headphones
Answer:	They are very clean sounding eqs.
Question:	does it connect to amplifier
Answer:	First, this is not a player. This is a tone control with instead of just the normal bass, treble and high, divides it into 31 (from 20HZ to 20KHZ). Also, this model is mono (1 channel). You can get 2 of these or get the stereo model. You still need an amplifier and a player. You hook this up between a like a CD player and your amp.

User questions & answers

Question:	Ok 9v, but how many mha are requierd to power it
Answer:	I’m not a fan of effects built-in to the amp (except maybe reverb). I have all of the 200 series pedals going into a clean amp. They sound amazing but, beware, the learning curve is steep.
Question:	Are Eq settings effected by a low battery, or is it designed to go dead once the battery doesn't have enough juice to funtion properly
Answer:	Any good quality power supply will do. (Zuma, voodoo etc.) I run a Zuma on my DD500, RV500 md 200 and es5 no issues
Question:	How many come in one order
Answer:	Pretty sure it’s designed for guitar, bass, even keyboards; BUT, assuming that you properly match up XLR/1/4” & mic/line level adjustments, I don’t see why not? I’d be willing to give it a try to see how it sounds. In fact, as an old user of the Boss GE-10 mono EQs - that I’ve tried on a mic before - I’d give it a go. I have 2 old GE-10’s that I use for different purposes in the studio; and now own 2 new EQ-200’s that I use for bass, guitar, and keyboards. You might like it differently, studio vs. live, but I’d say listen & see.
Question:	If BEQ700 equalizer is on 120 volt power supply (not battery) and if there is power interruption, is the device on or off when power is restored
Answer:	This one will provide more low end compared to the guitar one

Question:	Does this take calibration files (like .frd) to compensate for the frequency response of what you're pairing it with (even if it's the ECM8000 mic
Answer:	That’s a great question. I dont know that it does as it has no usb or sd car slot.
Question:	Can 1/4" aux outs exactly mirror XLR main outs
Answer:	Yes it can in fact I have a second amp on the aux channel
Question:	will this automaticly adjust the frequencies
Answer:	Yes, it will, but you wear an omnidirecional microphone (like ECM 8000) together.It is not so easy to do. There are so many adjusts, menus and options. If you are an advanced user, it should be easier. See the user manual. Best regards!

User questions & answers

Question:	I was thinking about using this for electric guitar. Is that feasible? I know this would be a tad overkill, but the feedback detection is nice
Answer:	LOL! Yes, total overkill. Like an Arnold Schwarzenegger movie. But why not? You could really shape the tone of your guitar. You could save a few bucks by getting a single unit vs the duplex unit. It's a good Eq and has some very useful extra features in it. My band uses a duplex unit for our monitors. Works great.
Question:	Are the rack mount brackets removable
Answer:	Yes I think. Are you sure you want to do that?
Question:	does it work with 220v
Answer:	Yes, it's auto 100 ~ 240V. You can read this on the back side below the power swith.
Question:	Can I rout this from mixer mains to eq then out to powered speakers or run it thru the board
Answer:	I route it after the board to the powered main speakers or to a power amp. you would have to use an effect loop any other way.I works well sliders are small so they are touchy on the fly but if you are sitting doing sound no issue.

Product description

Finding it hard to get the perfect sound from your guitar? Maybe your guitar gets lost in the mix? Do you have major feedback issues with your acoustic? The problem's not your guitar-you need an equalizer! You can instantly improve the sound of your guitar with a little help from the EQ700.Most performers don't have a clue about what good equalization can do for their sound. Maybe you've heard the old maxim, "Make a sine-wave to get really good sound," or "Make a smiley-face, that always works." Sadly, this qualifies as advice from the uninformed. Just as every room is unique, so is every musical instrument. Even guitars made by the same manufacturer, using the same materials, on the same day can vary a great deal.People provide a good example of this principal-although we are all similar, we don't all wear the same size shoes, or even have the same color eyes. There is no one "perfect" equalization curve that fits every scenario; equalization is dynamic.Most acoustic and electric guitar energy lies between 100 Hz and 6.4 kHz. Even slight changes in this range can cause a tremendous variation in overall energy and impact, as the human ear is especially sensitive to this range.Boosting frequencies around 200 Hz - 400 Hz often provides warmth and body, while boosting frequencies in the 3.2 kHz - 6.4 kHz range adds clarity to clean guitar signals. Depending on the amount of distortion, this same range can ruin the sound of an overdriven electric guitar by adding harsh harmonics.One of the most common mistakes is adding too much bass to acoustic guitars. If the low frequencies are boosted excessively, acoustics can easily get lost in the overall mix. Most acoustic guitars are also prone to feedback in the 200 Hz - 400 Hz range.A general rule of thumb-the best results are often achieved by finding and reducing the frequency bands that are offending, and then turning up the overall volume, rather than boosting on

User questions & answers

Question:	I have a digitech rp360 (multi effects pedal). would i run the guitar into this eq in front of the multieffect pedal or
Answer:	Try both. I would run it in front first and then try it after your RP360 with the settings you use. Let your ear tell you what you prefer. This pedal has more than one use so it's a hard question to answer correctly or incorrectly.
Question:	has anyone ever used this little device to boost up bass/treble for voice
Answer:	If the microphone that is being considered is the dynamic type, then it can be used in this experiment and it’ll boil down to the summed frequency boost & cut subjectively being what the individual is looking for. If the microphone being considered here is the Condenser type, it is best to pass as this kind requires a phantom power source that’s usually +48v and if the reader already knows how to make the condenser microphone work here, then it’s likely that the reader has a degree in electrical engineering and can just stop reading and proceed as they already know, or should know, what I’m going to explain, lol. Now, there is one major caveat that the user will have to deal with before pursuing the experiment. Both the signal level from the microphone, aka mic, and the impedance (unless the microphone being used is high impedance to begin with...high impedance mics use a cable that has a 1/4” male plug on the end that plugs into the mixer or an amplifier of some sort-unfortunately most mics are low impedance) will have to match the usual and customary level and impedance of what is fed into the pedal, e.g., a guitar. lol. The impedance match is the most important of the considerations and a direct box (or simply DI box) converts a hi-z or high impedance signal to lo-z or low impedance signal. Most will function in the reverse if one needs to convert lo-z to hi-z. As far as matching the level of the signal, that kind of depends on the microphone. Also, the graphic eq pedal that’s the heart of this matter has the ability to globally boost or cut the signal level. Most likely that’s only applied as the signal is outgoing. The signal has to have adequate but not excessive gain (the level I mentioned earlier) and in most cases, a dynamic mic signal won’t have adequate gain, so the outgoing signal, while boosted by the pedal, will be on the noisy side because of the lack of what is called headroom. If one has access to the kind of headphone amp common to both pro and quality home studios, plug the mic first into the output of the DI, then plug a cable running from the DI’s input side into the input of the headphone amp and the last cable into the eq pedal. The output of the eq pedal cab now be run to the mixer. Look for either a mixer channel identified as Hi-Z or a channel with a switch (usually a push button toggle but can be a slide or rocker) and plug the out from the pedal to this mixer Hi-Z input. Now follow Good Sound System Operation Practices (including making sure all the eq sliders are parked at the zero before powering by up the system) and see what you can cook up.
Question:	will this work 4 and arch top since my fender ramparte dose not have a treble mid and bass control nobs
Answer:	Sure. Set the equalizer like a wave. That is, the bass end nearest to the "Out" input should be above the 0-marking, then create a wave-type response, but my experience on the high end is only raise it one notch above zero. Then, you should be fine. This eq is excellent for acoustics and electrics, and your arch top will sound very nice. Dial the Rampart about half way up and enjoy. Should sound great! James
Question:	Will this pedal help remove the muddiness of a cheap distortion pedal
Answer:	Yes, it will remove the muddiness. Just notch out the midrange. This pedal does an EXCELLENT job with the traditional "smiley face" eq (boosted bass and treble). I removed the metal plate underneath it to lessen the weight, and use it in my pedal board. I've tried other eq's and this one is one of the best, especially considering the price.

Product description

The ULTRAGRAPH PRO FBQ1502 is a professional, ultra-musical 15-band stereo graphic equalizer that brings the best parts of your sound to the forefront while eliminating feedback.

Bring the best parts of your sound to the forefront.

FBQ feedback detection, low cut filter offer additional control.

Dedicated subwoofer output with adjustable crossover.

All the Good Stuff

The FBQ1502 features the amazing, patent-pending FBQ Feedback Detection System that instantly detects feedback frequencies and can also be used as an audio analyzer, making the FBQ1502 a welcome addition to any touring rack. Another FBQ1502 highlight is its dedicated mono subwoofer output with adjustable crossover frequency that lets you add some extra punch to your music.

The FBQ Feedback Detection System 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 makes what was once a labor-intensive search for feedback frequencies nice and simple.

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.

Pure, Musical Sound

This incredible rack unit goes the extra mile to make sure you sound your best. An additional low cut filter removes unwanted frequencies such as floor rumble, while a highly accurate 4-digit LED output metering and input gain control let you easily adjust levels. High-quality components abound, such as the ultra low-noise audio operational amplifiers for outstanding sound performance and the servo-balanced inputs and outputs with 1/4" TRS and gold-plated XLR connectors. Outstanding reliability is guaranteed with the high-quality illuminated faders, detent potentiometers and illuminated switches.

Balanced Inputs and Outputs

The Behringer ULTRAGRAPH PRO models feature electronic servobalanced 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).

User questions & answers

Question:	How many Microphones can it connect at the same time
Answer:	As many as your mixer will allow. How it is setup is you will run an aux send channel to the effects mixer and then back to the stereo channel. Then whatever channel you want the effects on you simply turn up the aux channel that the channel is sent from. If you need pictures or a better explanation my email is [email protected]
Question:	how do you hook it up using a cd player and a dac
Answer:	Thanks for the question- For a cd player, (or any accessory- dvd player, cable tv or a dish) your "audio OUT" plugs (one red, one white) get connected to the "audio IN" plugs on the equalizer. Then the Audio OUT from the equalizer gets connected to audio IN on your amplifier. Just remember Out from one component goes to IN on the next one. For the sound quality- set the amp bass and treble to neutral (midpoint) and adjust the equalizer to compensate for the speakers, the room and your preferences. For variation in the quality of source recordings- I sometimes adjust the sound using bass and treble on my amp. BTW to hook up an iPod etc- get a cable with the headphone jack (male pin) for the iPod and the red and white (RCA) male connections. The music goes OUT from the iPod and IN to either the equalizer or an AUX IN connection on your amp. OUT from one device and IN to the next.
Question:	do the rack brackets remove? need to put in cabinet with 18" or less width,thanks
Answer:	The rack ears/brackets are fixed and designed for standard 19 inch racks. They are not removable.
Question:	Can I use speaker level inputs from my ONKYO 818 receiver as inputs to this equalizer(135W RMS/channel
Answer:	I am sorry, I do not understand the question....inputs to inputs???? it should be a non-powered output from the onkyo to an input of the EQ. I do not understand what you are trying to accomplish here.....sorry.

User questions & answers

Question:	does it have 48v phantom for both XLR mic inputs
Answer:	No.
Question:	I have read this unit takes two racks spaces, albeit it states above it is 5.9 inches, so which is it? Thank you
Answer:	Just measured, the height is 3.5 inches.
Question:	Is this true?...i have been told that i cannot connect this to a onkyo 737 home theatre receiver because it does not have a tape loop
Answer:	Hi Steve. I looked up the Onkyo 737 so I could answer your question intelligently. I need to know how you want to use the EQ before I an give you a good answer. You could use the Zone 2 output to feed the EQ input and then connect the EQ output to another source input, say if you own a tape deck and you want to equalize the response, but I do not see the traditional "tape loop" that would enable you to equalize the front two channels irregardless of which source you pick. So the simple answer is no you can't use it effectively. Sorry.
Question:	whay are the in put / out put in each channel are crossing? like. rca has in put and out put on same channel
Answer:	RCA is unbalanced, meaning its susceptible to noise problems. XLR (and 1/4 trs - not 1/4 tr) are balanced, and more immune to noise problems picked up in interconnecting audio equipment. Balanced connections use shielded, twisted-pair cable and three-conductor connectors (like XLR or TRS connectors). This noise cancellation is called “Common Mode Rejection.” It's also good for long cable runs. And so XLR and TRS cables are used to transmit balanced audio from one balanced device to another. In an audio rack you might be tempted to use an inexpensive cable like RCA because the cable runs are short. That's your choice, but the professionals use XLR cables for the cleanest sound they can engineer.
