ACCESSORIES
LDA-SUB is specifically designed for subwoofer applications. It provides one channel with output power up to 2000W @4ohms. In addition it offers a full set of value added features such as on board DSP and RS485 connection for monitoring and control via dedicated PC software. To guarantee maximum reliability, the LDA-SUB includes a highly efficient universal switch mode power supply with PFC (Power Factor Correction) which provides a total 2000W power to the output channel. The output stage uses the well-known Pascal Class D XPRO1 module.

The LDA-SUB includes a set of sophisticated processes for loudspeaker,implemented by the powerful M704 DSP running 96kHz/24bit [96 bits precision for the internal intermediate processes] and high performance 24bit AD/DA Converters. Processes as Noise Gate, crossover filters, parametric EQs per input and output sections,RMS compressor, alignment delay and All-Pass filters are available, all in all everything needed to optimize a self-powered loudspeaker. Morever the Clip/Limiter function per channel provides output monitoring to prevent speaker damage with gentle gain reduction at clip threshold, in addition to the efficient heat dissipation system and Over-Heat protection which themselves ensure uncompromised reliability.

Furthermore the LDA-SUB is also equipped with a Dynamic Loudness function and an useful Pink/White noise generator. All setup parameters for input mixing, DSP features and the limiter setting are accessible by using the remote PC software.High Band can be splited or not in two sub-band. When the Xover split freq is enabled then the RMS compressor working on the lower band and a additional volume (hi_level) working on the Higher band.
