SoundImpress DIY Stereo Amplifier Kit | Powered by ICEpower

The SoundImpress DIY Stereo Amplifier Kit offers an exceptional opportunity to construct a high-power, professional-grade amplifier in your own workshop. Powered by renowned ICEpower technology, this kit delivers a formidable 400 watts per channel, making it an ideal choice for audiophiles and hobbyists seeking to build a robust system for home cinema, studio monitoring, or high-fidelity music reproduction. Its versatility also suits custom installations where reliable, clean amplification is paramount.

At the heart of this kit are two Class D amplifier modules, each rated at 400 watts into a minimum 2.5 ohm load, ensuring impressive headroom even with demanding speakers. The design boasts an efficiency of 84%, minimising heat dissipation and allowing for compact builds. Signal integrity is maintained through XLR input connectors, with an input impedance of 36 kΩ and a gain of 27.4 dB, while total harmonic distortion remains exceptionally low at just 0.006% THD+N. The output stage features gold-plated binding posts for secure, high-quality speaker connections, and a current limit of 30 amps protects both amplifier and speakers. Power is supplied via an IEC C14 inlet, simplifying integration with standard mains cables. This kit provides all essential components for a rewarding build, resulting in a powerful, clean-sounding amplifier that rivals commercial offerings.
