DM-500W+500W is a stereo amplifier module of 2 x 500W /4Ω RMS. 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 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. CH1 and CH2 can be bridged for mono applications. Auto Standby, conform to ERP Directive, and PFC options are also available.
