Features of Active Subwoofer: Built-in three-channel high-power DSP amplifier with output power: 600+600+1200W/8Ω, capable of driving full-range speakers of appropriate power. Standard configuration includes one FS115SUB with two FS4028s and one FS4012 coaxial monitor. With just a mixing console and microphone, sound reinforcement can be achieved. The entire performance equipment set can be easily transported in an ordinary car, truly enabling one person to complete a performance with just one car. One-in, three-out DSP module, efficient switching power supply with automatic voltage sensing, Class D amplifier module, 90-260V full-bandwidth PVM modulator, achieving ultra-low distortion, DC, soft start, thermal protection, short-circuit protection, peak limiting, truly solving various problems caused by heat dissipation in active speakers. Multi-band PEQ equalization adjustable for input and output. Inputs feature mute, noise gate, gain, phase, delay, and bypass. Crossover filter slopes range from 6dB/Oct to -48dB/Oct, including Butterworth, Bessel, and Linkwitz-Riley types.
