Stereo Graphic Equalisers

Notes: 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! BEHRINGER ULTRAGRAPH PRO Series equalizers take a giant leap forward technologically, providing robust feature sets and our proprietary FBQ Feedback Detection Systemiat a price that makes them a must-have for anyone who records or operates a live sound system.

The low frequency sound range requires special attention. That's why the FBQ1502 features a low cut filter, in addition to the frequency faders, to help remove unwanted low frequencies such as floor rumble, room resonance, electrical hum, etc. This filter is preset on the FBQ1502 to remove all content below 25Hz, which can really eat into your power amp's headroom.

The FBQ1502 features 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.

The FBQ feedback detection system is one of the most outstanding features of our graphic equalizers. This ingenious circuitry helps you recognize and eliminate feedback frequencies immediately. When feedback is sensed in a specific frequency range, the LED on the associated fader lights up, so you know at a glance which fader to lower to eliminate the feedback. Behringer'S proprietary FBQ feedback detection system makes it easy for even the novice operator to defeat live sound's natural enemy - feedback!

There are two reasons to buy a stereo EQ - to run your front of house system in stereo, or to use one side for mono front of house while the other side EQs your monitors, which is usually where feedback problems start.

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 high frequency

FBQ - Totally Feedback-Free:

For more than 20 years, BEHRINGER has designed and manufactured some of the most successful FBQ Feedback Elimination processors. Now you can own and enjoy the benefits of this technology, as we have integrated the revolutionary FBQ Feedback Detection System into this product, so your sound system is completely feedback-free, allowing you to focus on your performance. Utilizing an ultra-fast feedback detection system, this ingenious circuitry helps you recognize and tame feedback frequencies immediately. When feedback is sensed in a specific frequency range, the LED on the associated EQ fader illuminates, showing you at a glance which fader to lower to overcome the feedback. That simple!cy 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 top-notch German engineering, and the use of highest-quality components. Industry-leading 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.

Special Tools for Low and High Frequencies:

The low-frequency sound range requires special attention. That's why the FBQ1502HD features an ultra-effective Low-Cut filter on each channel, to help remove non-essential bass content, such as floor rumble, room resonance and electrical hum, etc., which really uses up your power amp's headroom. This added high-precision control gives the FBQ1502HD the power to accurately fine-tune your system's overall sound, creating crystal clear and dynamic output - with incredibly tight and punchy bottom-end!

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. Just another example of how BEHRINGER saves you money.

Stereo or Double-Duty?

The FBQ1502HD is designed to improve your sound from every angle: it's a great stereo Front Of House (FOH) equalizer; or, you could use one side for mono FOH, while the other side EQs your monitors - which is where you need the maximum feedback control.

Superb Audio, Sound Value

When you want to bring out the very best from your sound system or your performance, in the studio or at your next live gig - put your trust in the ULTRAGRAPH PRO FBQ1502HD. We dare you to compare it to the competition. Once you do, you'll choose BEHRINGER again and again for both audio quality and value.

Notes: The CEQ215 is a 19" rack mounted dual 15-band graphic equaliser, which allows the adjustment of labelled frequencies via the individual cut/boost faders.

Up to 12dB of cut or boost for frequencies ranging from 25Hz to 16kHz for accurate audio spectrum control.
