Three-way, tri-amplified bass-reflex sound system that offers a convenient plug and play solution for DJ sets and small musical groups performing live in small to medium sized venues. The analogue audio processor with 24 dB/oct electronic crossover network and ADAP (Advanced Dynamic Active Protection), a 15” subwoofer and three PWM processed class D power amplifiers (500W + 2 x 150W) with switch mode are contained in a single ultra lightweight, yet extremely sturdy polypropylene enclosure. A storage compartment in the rear houses the two 2-way satellite speakers, allowing the wheeled system to be transported as a one piece unit. There is also a buil-in 14-channel mixer with 6 x XLR mic inputs with phantom power supply, 2 x mono inputs and 4 x stereo input channels, 3-band EQ, 99 selectable digital effects with effects send and return controls; USB input/output for playback of music programs/files from a computer or for recording from the master audio output to a computer with recording program; and multi-function knobs to block, unblock, and remove the cover/ lid transport handle. The subwoofer is equipped with 15” high efficiency and high excursion custom woofer with 3” voice coil. Each of two satellite speakers features a 6.5” woofer with 1.5” voice coil and a 1” compression driver coupled to a 90-degree x 60-degree constant directivity horn.
