DM-300W+150Wx2 PCF is a 3 channel amplifier module of 300W + 2x 150W /4Ω RMS. This module, used in some product of the brand, is also available as component for other manufacturers. Based on Class-D architecture, the module uses a switched-mode power supply equipped with a PFC (Power Factor Correction) circuit improving the energy efficiency. Light, compact and very reliable, DM amplifiers 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.
