Audiofy is the simple yet powerful integrated multiroom professional audio system created by ThinKnx. Only one device combines audio matrix routing, power amplifiers for each output and up to four independent network players. It is also fully configurable via web. The system permits to spread audio contents from external analog sources or from internal players towards up to 16 rooms with superior pure sound quality. Thanks to the many protocols supported, it is perfectly integrated inside automation systems. A native KNX TP port allows to send commands to the music system directly from other KNX devices and to receive feedbacks. Through this app, the final user decides the routing of the audio sources and has a complete control over his music listening experience. The internal players are controlled directly from the app, the music library provided by a NAS or USB stick can be browsed with a simple menu.
