DM-700W+700W PFC is a 2 channel amplifier module of 700W + 700W. This module, used in some active speakers of the brand, is also available as component for other manufacturers. Based on Class-D architecture DM-700W+700W PFC uses a switched-mode power supply equipped with a PFC (Power Factor Correction) circuit improving the energy efficiency. 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. CH1 and CH2 can work on bridged mode.
