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.
