ICEpower300A2 is designed for outstanding audio quality in a compact size. The 300A2 incorporates the latest in state of the art custom ICEpower patended ICEedge Chipset technology, enabling superior sound quality with an ultra-low noise floor, of typical 22 µV for a SNR ratio of 123.5 dB. It is an efficient two/one-channel audio power amplifier intended for driving two 4 Ω loudspeakers or one 8 Ω speaker in BTL mode. The ICEpower300A2 provides comprehensive protection and monitoring functions with an easy-to-use control interface. Additionally, dedicated monitor outputs for loudspeaker connector output voltage enables real time protection system of the loudspeaker. ICEpower300A2 is designed for high continuous output power, making it ideal for applications requiring sustained output power not only for home hi-fi, but also for demanding studio monitor and high performance amplifier for PRO audio speakers as well.

To power one or two 300A2 modules, the switching PSU 1500S was specially developed by Icepower, a powerful SMPS capable of delivering 1500W with peaks of 2400W.

SMPS 1500S

Based on ICEpower's years of advanced research and experience in switching power supplies. the 1500S module is a 1500 W RMS power supply. Available in three different versions with rail voltages of ± 47V, ± 57V or ± 69V. It features a universal mains PFC based main power supply and a 60W auxiliary power converter. The 1500S is designed to be used with one or more 300A2 or 400A2 amplifiers.
