DM-600W+150W is a 2 channel amplifier module of 600W + 150W. This module, used in some active speakers of the brand, is also available as component for other manufacturers. Based on Class-D and Class-AB architecture the DM modules are light compact and very reliable. They feature thermal, short-circuit and overload output protection. The temperature can be controlled via a 12V DC output connected to a fan. Over voltage protection and DC offset shutdown are also available.
