Description
The AudioCenter GT512A is a 12-inch active DSP-controlled full-range loudspeaker for professional portable and installed sound systems. AudioCenter’s BrainCore™ platform combines a customized 12-inch low-frequency driver, a 1-inch-exit high-frequency driver, Class-D amplification, and FIR-based DSP in one self-powered enclosure.
The GT512A provides 1,100 watts RMS, a published maximum calculated output of 128 dB continuous and 134 dB peak, and a 42 Hz to 20 kHz response. The integrated 48 kHz processor includes MAIN, LF BOOST, and W/SUB presets for stand-alone use or operation with a separate subwoofer.
The rotatable 90-by-60-degree coverage pattern and symmetrical 45-degree monitor angles allow the cabinet to serve as a front-of-house speaker or floor monitor. CNC-machined plywood, a polyurea finish, suspension points, and dual-position pole mounting support touring and fixed-installation use.
