ASX Series

Power to the pros

Take audio reproduction to the next level with the ICEpower ASX Series. These ultra-compact, lightweight class D audio amplifiers with integrated power supplies are designed as highly competitive modules in terms of low cost and carefully chosen features. The four modules in the ASX Series can be combined as application building blocks to generate a wide variety of 1-8 channel audio applications in consumer or professional audio products.

Forever young – the ASX Series

Flexibility, quality, and reliability is paramount to the ASX Series. The modules have an extraordinary solid build, and are fully protected ensuring a long lifetime. Due to their compact size, the ASX solutions are suitable for innovative product architectures, bringing a new, exceptionally powerful experience to audio reproduction.

The ASX Series is fully compatible with our extension module, ICExtend. By integrating ICExtend in your application, you can easily add ErP (1275/2008) compliant stand-by functionality, universal mains, and +5 V auxilliary power supply. The modules are based on ICEpower’s HCOM class D topology resulting in extended bandwidth, improved dynamic range, and exceptionally low distortion.
