MODULE ICEpower200AC Compact Audio Amplifier Module 200W @ 0.2% THD+N Dimensions: 10.7 x 5.5 x 3.3 cm The ICEpower200AC is an intelligent 200W audio amplifier solution designed particularly for highly competitive consumer, professional and multimedia audio applications. The ICEpower200AC can be used separately or as a supplement to ICEpower modules with integrated power supply for compact multi-way or multi-channel solutions. The ICEpower200AC can be powered from the ICEpower200ASC, ICEpower250ASP and ICEpower500ASP amplifiers. Each of these amplifiers are able to power up to two additional ICEpower200AC amplifier modules from the integrated power supply. The ICEpower200AC is preapproved for safety and EMC to reduce design-in cost and shorten Time-to-Market.
