Behringer Ultragraph Pro GEQ3102 31-Band Stereo Graphic Equalizer - Used

Looking for precise, surgical room correction or dual-channel tone shaping for your live rig or studio setup? The Behringer Ultragraph Pro GEQ3102 delivers high-resolution 31-band graphic equalization per channel, providing total control over your frequency spectrum. Featuring constant-Q filters, sweepable high-pass and low-pass filters, and dedicated subwoofer outputs, it’s a versatile and reliable rackmount workhorse for taming feedback, tuning acoustic spaces, or shaping mix buses.

Condition is Very Good overall. The unit shows normal light cosmetic rack wear and minor surface scuffs from careful standard use (see photos for detail). Please note that one low-cut filter knob cap is missing on the front panel; however, the pot shaft remains fully intact and the function remains 100% usable and operational.

Our technicians have thoroughly tested the unit, verified slider and pot cleanliness, tested switch responsiveness across all frequency bands, and confirmed proper operation across all inputs and outputs.
