A full-range 4-channel amplifier that maintains 250W×4 from 4Ω down to 1Ω using a next-generation Class-A/D circuit—an accomplished unit built by combining the technologies of the Power Series.
This full-range 4-channel power amplifier from the Power Series uses the new-generation amplification circuit “Class-A/D” to achieve a compact size, high power, and high efficiency. With constant power technology, it maintains a rated output of 250W×4 at any load of 4Ω/2Ω/1Ω, and pursues high-quality playback with a signal-to-noise ratio of 95dB. It is a high-end model that serves as the core of a full-fledged multi-channel system.
