SoundImpress DIY 4CH amplifier kit | Powered by ICEpower

The SoundImpress DIY 4CH amplifier kit offers a compelling opportunity for audio enthusiasts to construct a high-performance, multi-channel amplification system. Delivering a formidable 400 watts per channel into a minimum load of 2.5 ohms, this Class D design is ideally suited for powering demanding loudspeakers in a home cinema setup, a dedicated stereo bi-amping configuration, or a professional studio monitoring environment. The kit’s exceptional 84% efficiency ensures minimal heat generation, allowing for more compact enclosure designs without compromising on output.

Engineered around a proven ICEpower module, this amplifier kit guarantees pristine audio reproduction with an impressively low total harmonic distortion of just 0.006% THD+N. The balanced XLR inputs provide excellent noise rejection over long cable runs, while the gold-plated binding posts on the output ensure a secure, corrosion-resistant connection to your speakers. With a fixed gain of 27.4 dB and an input impedance of 36 kΩ, integration with a wide range of preamplifiers is straightforward. The IEC C14 mains inlet simplifies power cabling. This comprehensive kit empowers you to build a truly professional-grade, four-channel amplifier that rivals commercial offerings at a fraction of the cost.
