4-kanalni ojačevalnik, 4x200W DAP Audio Qi-4200

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 and bridge mode can be set for each stereo pair. With the SMPS and 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 and it’s connected speakers. It has a short circuit/ thermal, DC ,RF protection and a soft start system. The Qi-amplifiers are made with high-quality low deviation components to ensure a perfect sound quality and a long life time.
