LA-XD18A
18″ HIGH-PERFORMANCE ACTIVE SUBWOOFER ARRAY MODULE WITH DSP
PRODUCT FEATURES:
Each speaker is equipped with a 1x1200W DSP power amplifier, featuring a 48KHz sampling frequency, 32-bit DSP processor, and 24-bit A/D and D/A conversion. It provides an RS485 interface for computer connectivity, allowing simultaneous connection of up to 64 machines for debugging and external computer control over 1500 meters. The highly efficient switching mode power supply includes automatic voltage induction. The class D power amplifier module, coupled with a full bandwidth PVM modulator, ensures ultra-low distortion. Additional features include DC protection, soft start, thermal protection, short circuit protection, and peak voltage limit, addressing various issues related to active speaker heat dissipation. The DSP module input features 31 segments of parametric equalization with adjustable bandwidth, including silence, noise gate, gain, phase, delay, and bypass. The output comprises 10 segments of equalization with adjustable bandwidth, alongside mute, high-low-pass filters, gain, phase, delay, bypass, compressor, and divider filters with slopes ranging from 6 dB/oct to -48dB/oct.
PRODUCT ADVANTAGES:
- Enhanced sub-low frequency response with a single 18-inch bass design, delivering deep and powerful bass.
- Designed for directional, wide, long-distance projection sound reinforcement with high sound pressure levels.
- Versatile applications, including theaters, multi-function halls, churches, schools, sports fields, and both indoor and outdoor performances.
- Ideal for language amplification, ensuring clear and precise sound reproduction in various environments.
