DM-350W+175W is a 2 channel amplifier module of 350W /4Ω + 175W /8Ω RMS. This module, used in some products 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, overload output protection and DC offset shutdown. A bridgeable version of 600W/8Ω with same dimension is available, but some components need to be changed.
