SoundImpress DIY 4CH amplifier kit | Powered by ICEpower

The SoundImpress DIY 4CH amplifier kit offers an exceptional opportunity for audio enthusiasts to construct a high-power, multi-channel amplification system. Delivering a formidable 700 watts per channel, this kit is powered by renowned ICEpower modules, ensuring professional-grade performance for demanding applications. Whether you are building a dedicated home cinema setup, a multi-room audio system, or a high-fidelity stereo configuration requiring bi-amping, this versatile four-channel design provides the flexibility and headroom needed to drive even the most challenging loudspeakers with authority and precision.

At the heart of this kit lies a Class D amplifier topology, achieving an impressive 80% efficiency while maintaining remarkably low distortion of just 0.005% THD+N. The input stage features four XLR connectors, offering balanced connectivity for superior noise rejection, complemented by a 38 kΩ input impedance and a fixed gain of 25.8 dB. For speaker outputs, gold-plated binding posts ensure reliable, corrosion-resistant connections, while the minimum load of 2.7 ohms per channel allows for driving multiple speakers in parallel. The IEC C14 power inlet simplifies mains connection, making this kit an ideal foundation for a custom, high-performance audio system that rivals commercial offerings.
