Description
The AudioCenter SA315 Plus is the 15-inch model in the SA3+ active DSP-controlled loudspeaker family. AudioCenter’s BrainCore™ platform integrates a customized 15-inch low-frequency driver, 1-inch-exit high-frequency driver, Class-D amplification, Bluetooth, and an LCD-controlled DSP in a professional CNC-machined plywood enclosure.
The rear-panel encoder and LCD screen provide direct access to MUSIC, FLAT, SPEECH, and W/SUB presets. These modes adapt the loudspeaker for full-range music, speech reinforcement, or use with an active subwoofer. XLR/6.35 mm combo input, 3.5 mm input, wireless Bluetooth, and balanced XLR output support multiple source and linking configurations.
The SA315 Plus provides 1,000 watts RMS and 2,000 watts peak, with a published maximum calculated output of 128 dB continuous and 134 dB peak. Its symmetrical 45-degree monitor geometry, M8 suspension points, and 35 mm pole socket allow front-of-house, floor-monitor, suspended, or stand-mounted deployment.
