A Series

ICEpower // Products // Other // A Series

Small size. Great versatility.

The ICEpower A Series consists of three high-performance general-purpose class D amplifiers. Essentially the same as the amplifiers on the ASP modules, they are available in power variants of 250 W, 500 W and 1000 W.

They can be used on their own, powered by a linear power supply, or they can be powered by the hanger bus from the modules in the ASP series for creating 2 channel amplifiers, 2-way and 3-way active speakers.


Below you can see the application possibilities for the A Series. If you have any doubt or questions, please contact our sales team.
