Power that moves

With 2200 watts of power, the built-in Class D power amplifier achieves impressive sound pressure levels with ultra-fast Attack and natural transient reproduction with very low heat loss. The power amplifier is so energy-efficient that it does not require a ventilation fan. Instead, it is mounted at the rear of the enclosure on a fixed heat exchanger with no moving parts. The stereo signal input path with crossover has been optimized for low distortion and features an advanced limiter for added safety, preserving the sound characteristics of the input signal at all levels. RCF power amplifiers are standardized for maximum safety (EN62368-1) and are powered by a highly efficient and ultra-light switching power supply.
