Description
The AudioCenter SA312 Plus is a 12-inch active DSP-controlled loudspeaker built with AudioCenter’s BrainCore™ technology. The SA3+ platform combines a customized low-frequency driver, a 1-inch-exit high-frequency driver, Class-D amplification, wireless Bluetooth, and an LCD-based DSP interface in a portable CNC-machined plywood cabinet.
A rear-panel encoder and LCD screen provide direct access to the DSP menu. MUSIC, FLAT, SPEECH, and W/SUB presets allow the speaker to be configured for full-range playback, voice reinforcement, or operation with an active subwoofer. XLR/6.35 mm combo input, 3.5 mm input, Bluetooth, and balanced XLR output provide flexible source and system-linking options.
The SA312 Plus delivers 1,000 watts RMS and 2,000 watts peak, with a published maximum calculated output of 126 dB continuous and 132 dB peak. Symmetrical 45-degree monitor geometry, M8 suspension points, and a 35 mm pole socket support front-of-house, monitor, suspended, or stand-mounted use.
