    High Fidelity Power Output Switching Power Amplifier Overload Protection For Loudspeakers

    2.1 Channel Power Amplier Module DM3000 for 2 Way or 3 Way Self-Powered Loudspeakers


    DM3000


    DM3000 is a complete solution dedicated to 2-way or 3-way self-powered loudspeakers. Designed to meet different applications, it provides 2.1 channels with output power of 2x800W+2000W @4 Ohm. Moreover the 2.1 channels can be bridged into a powerful single 1500W+1500W@8Ohm channel in order to drive i.e. Subwoofers or Multiple Ways Cabinets with Passive Xovers. In addition, it offers a full set of added value features such as onboard DSP and RS485 connection for monitoring and control via dedicated PC software. To guarantee maximum reliability, the DM 3000 includes a highly efficient universal switch mode power supply with PFC (Power Factor Correction) which provides a total 1500W power to the 2.1 output channels. The 2.1 output stages use an advanced Class D module.


    The DM 3000 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, Peak Limiter, alignment delay, all in all everything needed to optimize a self-powered loudspeaker. Moreover, the efficient heat dissipation system and Over-Heat protection ensure uncompromised reliability. Furthermore, the DM 3000 is also equipped with a useful Pink/White noise generator. All setup parameters.
