Features Peavey’s patented FLS® Feedback Locating System
The SEQ-2 is an embedded accessory that provides two independent channels of graphic equalization. Five trimpots on each channel adjust boost and cut, up to ±12 dB, at 40 Hz, 160 Hz, 630 Hz, 2.5 kHz, and 10 kHz. Each band has a Q of 0.75.
Custom frequencies and Q values are available by special order.
Why do I need an equalizer? 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.
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 specifi c 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—voilà, 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 fi lter 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 amplifi ers provide outstanding sonic performance. In addition, all Mini Series components may be stacked to create an ultracompact signal processing solution.

Automatic Feedback Destroyer with Integrated Microphone Preamp, Delay Line, Noise Gate and Compressor
Looking for feedback control? Maybe you need a compression or noise gate? Or a great DI box for line-level instruments? Whether you use it with microphones, acoustic instruments, or as a delay line for large venue loudspeaker systems, the FBQ100 is a “must-have” for your live and studio toolkit.
Quick and Clean Thanks to its intelligent “Learn Mode,” the FBQ100 can automatically equalize your PA and protect your sound system from feedback. BEHRINGER’s search algorithm ensures feedback frequencies are attenuated within a fraction of a second, using narrow 1/60 octave single-shot filters. The remaining filters automatically take action as required, adjusting only the specific frequencies causing the feedback, so your music stays powerful and alive.
Beyond Versatile The adjustable mic preamp, with switchable +48 V phantom power and Ultra-Low Noise technology, guarantees noise-free, ultra-musical sound. You can choose professional studio (+4 dB) or microphone output level, so the FBQ100 can be directly connected to the mic input of a recording device. Virtually any type of signal can be connected and converted.
Delay lines are required to compensate for time variations resulting from speaker positioning in large venues. The FBQ100’s delay can be adjusted in meters, feet or milliseconds. The maximum delay time of 2.5 seconds corresponds to a distance of 850 meters. Combining several FBQ100s with the optional rack-mount kit puts a complete professional loudspeaker management system at your fingertips.

The algorithm then sets extremely narrow notch filters (up to 1/60th of an octave) to “destroy” feedback frequencies, leaving the remainder of your signal virtually untouched. And with the “Set-and-Forget” default setting, plus the Panic button, your FEEDBACK DESTROYER can be up and running in a matter of seconds.
Ease of Operation The Auto Mode continuously monitors the mix, resetting programmed filters automatically, while the Manual Mode allows individual programming of up to 40 fully-parametric filters with frequency, bandwidth and gain adjustment. Open MIDI architecture makes future firmware updates and flexible communication with digital equipment exceedingly simple.
Be Prepared With the FBQ2496's various modes, you can master just about any live sound situation or use the unit as a creative sound-shaping tool. A single FBQ2496 can protect you from feedback in both your mono PA mains and a monitor mix. And the FBQ2496 is more than just handy—it's affordable!

The HQ231 Dual 31-band Graphic EQ is perfect for any live sound application where there is a high feedback potential including monitor mixes, side-fill cabinets or high powered front-of-house mixes situations.
The HQ231 features ART's proprietary FDC (Feedback Detection Circuit), with constant Q circuitry capable of delivering a 3% center frequency accuracy. Professional features like LED level metering, selectable 6dB or 12dB slider range, active balanced and unbalanced input & output connectors, RFI filters, independent variable Hi Pass (low cut) and Low Pass (high cut) filters, variable input level control, passive bypass switch, clip level indicator, ground lift switch, and selectable line voltage switch make it ideal for any professional application or touring system.
FDC Feedback Detection Circuit FDC (Feedback Detection Circuitry - designed and developed by ART Engineering) instantly illuminates an LED on the corresponding EQ band fader with the greatest sustained signal. The LED indicators can immediately show which band corresponds to the feedback frequency, allowing the sound engineer to reduce gain in that band to quickly kill the feedback while having a minimal impact on the sound of the live program material.
The FDC also acts as a simple spectrum viewer while the concert proceeds showing where the "hot" areas are. During system setup and sound check, the FDC may be used to help identify room and sound system resonances. By increasing the gain until feedback, it is easy to identify those frequencies that are likely to be problems. Reducing the gain in these bands helps tune the sound system, and, remove problem areas before the show begins. It also helps increase the gain margin before feedback.
Constant-Q Filtering The HQ231 features Constant-Q Filtering, which helps the HQ's FDC work with greater efficiency while offering superior overall performance of the EQ. Constant-Q ensures that even when making radical adjustments to a frequency band, that adjacent bands will not be affected. This is particularly critical in professional applications including monitor mixes and feedback control.
Professional Feature Set Professional features like 45mm center detent sliders with selectable boost or cut range of 6dB or 12dB ensures the HQ231 can be used for radical tone shaping, or precise control of a sound system. Versatile connection to any live sound system or installation can be easily made using balanced XLR, 1/4-inch TRS and unbalanced RCA input and output jacks included on the HQ231 back panel.
High and low pass filters, analog level metering, variable input level controls, signal clip level indicators, ground lift switch, internal power supply and selectable line voltage complete the HQ231 Dual 31-Band Graphic EQ's full feature set.

The visionary design of the dbx 12 Series makes your job easier.
The dbx 12 Series Equalizers were precision engineered to provide years of maintenance-free operation in any application. The magnetically isolated transformer, electronically balanced/unbalanced inputs and servo balanced/unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire relay bypass with 2 second power up delay were steps our engineers took to ensure compatibility for all installations. Only the best components were utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR (ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail is contained in a 3U steel/aluminum chassis.
