Behringer Ultragraph Pro FBQ3102 31-Band Graphic Equalizer

Extremely high-resolution, 19" rack-mountable analogue stereo equalizer with 31 frequency bands, Feedback Detection System and digital in/outputs for professional studio or live use.

The Behringer Ultragraph Pro FBQ3102 is an extremely high-resolution, digital stereo 31-band equalizer and feedback destroyer.

The equalizer section contains three switchable levels (12 dB, ± 6 dB and 0/-24 dB) and 31 high-quality, illuminated 45mm faders. A switchable true fader function assigns the fader position precisely to a relevant frequency curve. In addition, the FBQ3102 features a switchable low cut and high cut filter, a noiseless noise gate/peak limiter and a pink noise generator, as well as a stereo imager for amazing spatial settings and improved stereo management.

The revolutionary feedback detection system instantly recognises and eliminates the critical feedback frequencies, whilst at the same time acting as an audio analyser. These critical frequencies are displayed by the built-in LEDs on each control whilst the LEDs for any uncritical frequencies are dimmed. This way, you can quickly intervene to eliminate any feedback or interference frequencies.

The Behringer Ultragraph Pro FBQ3102 also offers servo-symmetrical inputs and outputs with gold-plated XLR and 6.3mm jacks. Thanks to its mono subwoofer out with variable crossover, it’s easy to polish up the sub regions of your sound.

Behringer’s high-standard design, the system’s analogue feel and excellent range of connection options make the FBQ3102 an indispensable tool for studio or live use.
