1000W Class-D power amp technology, a 3-channel digital mixer with gain setting recall that is “wireless ready” for our ULM Series digital microphone. Integrated DSP and exceptional portability. Then we loaded the B12X with our best 12" long-excursion driver for incredibly deep bass, and a state-of-the-art 1''. Phenolic diaphragm compression driver for exceptional high-frequency reproduction. Built-in Bluetooth connectivity allows you to stream music from your smart-phone, tablet or other Bluetooth-equipped device and you can even control the system via our free iOS/Android mobile apps. The B12X features a fully addressable onboard digital mixer with two combo jack/XLR connectors that accept balanced and unbalanced connections for dynamic mics and line-level instruments. The simple and intuitive user interface consists of a single rotary push-encoder with process, setup, exit and enter function buttons. A beautifully-backlit LCD display controls DSP functions including mixer parameters, 3 band EQ and presets.
