DM-500W+500W DSP and DM-600W+150W DSP are 2 channel amplifier modules respectively of 500W +500W and 600W + 150W RMS. These modules, used in some products of the brand, are also available as components for other manufacturers. Based on Class-D and Class-AB architecture the DM modules are light compact and very reliable. They use thermal, short-circuit, overload output protection, over voltage protection and DC offset. The temperature can be controlled via a 12V DC output connected to a fan. Both modules are equipped with a DSP chip controlled by a MCU. So, functions like EQ/Compressor can be implemented through a dedicated interface like USB or WIFI for parameter settings.
