The Qi-amplifier range is developed for installation use to create a perfect match with the Xi installation speaker range. Due to the rugged steel housing it can also be applied for mobile use. With only 1U it gives power for 4 channels. All 4 channels are individual controllable & bridge mode can be set for each stereo pair. With the SMPS & Class-D amplification it is a light weight solution with a high efficiency power consumption / power output ratio. An advanced protection circuit will protect the amplifier & it's connected speakers. It has a short circuit/ thermal, DC, RF protection & a soft start system. The Qi-amplifiers are made with high-quality low deviation components to ensure a perfect sound quality & a long life time.
