Equally suited to both live and studio environments, the ULTRAGRAPH-PRO FBQ3102HD from Behringer is dual-channel 31-band EQ featuring a proprietary FBQ feedback detection system, a handy tool for identifying problematic frequencies in a room, or for use as an audio analyzer. Additional hi- and low-cut filters, sweepable in frequency, aid in mitigating unwanted hiss or rumble, while ultra-low noise 4580 operational amplifiers seek to bolster the sonic performance of this unit. Utilizing an on-board crossover frequency selector, a dedicated mono XLR out helps separate frequencies that are more suitable for the subwoofer than the mains. The unit also provides both 1/4" TRS and XLR connection points.
