The M100 Stereo Amplifier Multiuser audio system is characterised by versatile technical equipment, such as an amplifier with 2 × 200 watts sinus, an FM tuner and a CD/DVD player. The high-end audio system features a backlit, real-glass user interface and can easily be expanded to include new technologies, thanks to the modular approach. It can also be integrated into a multiuser or multiroom system as well as into a KNX-based smart home environment.
