An additional low cut filter removes unwanted frequencies such as floor rumble. Accurate 6-digit LED input/output meters and level control are provided for precise level indication. Long-term reliability is guaranteed with Behringer's high-quality illuminated faders, potentiometer and illuminated switches. The ultralow noise audio operational amplifiers offer outstanding sound performance. In addition, all Mini Series models can be stacked on top of each other to create an ultra-compact signal processing solution. 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 1k, 2k and 4k (Hz), make up the fundamental zone of most musical instruments and the male and female vocals. 8k and 16k 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. Thatʼs why feedback typically gets louder and louder the longer itʼs allowed to occur. Needless to say, this kind of feedback is very undesirable. This is where the FBQ800ʼs 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 thatʼs 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 floor 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 roomʼs acoustics. For instance, if the room youʼre in is "bass-heavy,” lowering the 63 and 125Hz faders can help eliminate an overall "boomy” or "muddy” sound. Likewise, gently boosting the 8 and 16k sliders can add sparkle to a somewhat "dark” mix. Are the vocals getting lost in the mix? Raising the level of the 1k slider can help bring them out. Itʼs important to note that raising a single fader level is not always the best solution; itʼs 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, FBQ800ʼs 6-digit LED I/O meters and level control are provided for precise level maintenance. Long-term 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 can be stacked to create an ultra-compact signal processing solution. Mini Series mixer with built-in feedback detection. FEATURES

The vintage-style fully stereo 1974 four band Parametric Equaliser provides exceptional analogue musicality and sonic clarity, taking it\'s inspiration from 1970\'s-era gear. It has the ability to perform subtle shaping for mastering purposes that require a delicate touch and easy recall, but is just as capable of tonal sculpting, adding the analogue warmth and character that is near impossible to emulate in the digital domain.

Get immersive with the stereo operation, with one set of controls for both channels. The versatile design features dual channel precision stepped potentiometers, providing exceptional accuracy for fast and simple recall. The fully variable bandwidth allows you to control the parametric mid bands, making adjustments as surgically precise or as broad and natural sounding as you could ever require. Fully adjustable low and high cut filters are also included, ideal for tuning out undesirable signals at the frequency extremes. It also features switchable slopes on the low and high bands, allowing you to alter the focus at the top and bottom frequencies plus a low peak setting that magnifies the bottom end. The 1974 is perfect for tonal shaping, staying true to the sound of the 70s and ideal for any musician.

Genuine Stereo Operation with Indented and Accurate Potentiometers. The genuine stereo linked operation of the 1974 makes adjustment quick and extremely simple using just one set of controls to alter both channels. Gone is the wasted time spent fiddling about on every control trying to match the settings of the left and right channels with each other. The 1974 uses precision potentiometers, each one being matched for left/right accuracy to within fine tolerances by our trained technicians, so that both channels operate identically, and also have indented operation, providing exceptional accuracy for fast and simple recall.

Fully Parametric with Totally Variable Bandwidth. The 1974 is a true \'parametric\' equaliser, with the four bands having fully variable frequency controls and offer cut and boost of +/-12dB\'s. However, unlike EQ\'s with a no bandwidth adjustment, or a simple switch, the two mid bands have completely variable filter bandwidth controls enabling the user to focus in on very narrow sections of the audio spectrum or apply a broad natural sounding filter, or, of course, anything in between the two. This makes the 1974 incredibly versatile and capable of modifying everything from subtly fine tuning mixes to tone sculpting problematic recordings.

Variable Low and High Cut Filters. The 1974 also includes fully variable low and high cut filters, ideal for tuning out undesirable signals. The low cut (otherwise known as High Pass Filter) having a range of 10Hz-225Hz and the high cut (otherwise known as Low Pass Filter) 4kHz-32kHz. The beauty of being fully variable is that, unlike fixed frequency filters, it is easy to sweep both controls to find the perfect setting and remove sounds with pinpoint accuracy. This is especially useful when bracketing individual tracks where it will be necessary to cut the bass to remove rumble and top to remove hiss, as these undesirable signals will just add up as the tracks are layered. For instance, cut everything instrument below 100Hz except those within that spectrum, such as the kick, bass or synths etc to provide extra headroom to work and also tighten up the bass making it sound less muddy. And likewise for the high frequencies.

Switchable Slope Setting. Very few analogue parametric equalisers have an adjustable slope on the low and high band filters, and is yet another feature of the 1974 that allows you to take control of your audio. The filter slopes of the 1974 have been chosen for their musicality - allowing you to adjust the focus of the audio at the bottom and top ends of your recording but not so harsh as to be a very noticeable brick wall filter. At the bottom end slopes of 6, 9 and 12dB per octave plus a Peak setting are available, and at the high end 6 and 12dB\'s per octave.

The Peak setting is quite a unique feature in that it adds a narrow bell shape to the 12dB per octave low band filter at the knee frequency just before it rolls off. Especially useful on kick drums, it magnifies and gives extra weight to the hit whilst still filtering out any subsonic junk and without muddying the lower mid. It\'ll give your kick an added sense of power and precision.

Features:
  • Vintage-style four band Parametric Equalisation which takes it\'s inspiration from 1970\'s-era analogue gear.
  • Delivers classic sonic clarity and control at an affordable price.

 DBX 2231 Dual 31-Band Graphic Equalizer with noise reduction

It's amazing. One little button. It has so much effect. The Type III? Noise Reduction is an entirely new concept... virtually instantaneous encode/decode within the circuitry of the box. We started out to build the finest EQ's possible, boxes with the heritage and performance to rival our famous 30 Series EQ's. And to no one's surprise they came out awfully darn good. (Ask to see the Audio Precision plots compared to the competition.) But then, Roger (our chief engineer, a nice guy, as far as engineers go) got the crazy idea of putting this new noise reduction stuff in the box. We listened to it and were amazed. The EQ's sounded great without it but with it the performance was nothing short of incredible. Check it out yourself and see.

But hey, Roger wasn't about to stop there. PeakPlus? Limiter. Who knows more about limiting than the folks at dbx?; nobody... that's who. So when the guys were developing this new series of EQ's they wanted something that would be unique to these EQ's. That's when Roger got another one of his bright ideas and said "I bet they'll work a lot better if there's a cool limiter built in." Next thing you know, all the guys are in the studio amazed at the new limiter Roger had designed specially for the 20 Series. Once again, hearing is believing... With a threshold range of 0 to +20dbu, the PeakPlus limiter is designed to tame your program material from the subtlest nuances to the rowdiest hits. Also, the four stage LED ladder gives you a great visual indication as to what the limiter is doing.

20 Series EQ's. You used to have to settle for second best in a reasonably priced EQ but not any more. With the new 20 Series from dbx Professional Products you get a great EQ circuit, a graceful yet powerful limiter and the revolutionary new design of the Type III? Noise Reduction. Check out the dbx? 20 Series graphic EQ's at your pro audio outfitter. You'll see, with the 20 Series EQ's you get both MORE!!!
