We recommend Ethernet, especially for telephony and synchronised multiroom audio. Wi-Fi is possible as an alternative. Each room needs a power socket and ideally a network socket. ### What happens during a power cut? The Audio Decks restart automatically when the power returns and reconnect to the server. The system runs read-only, so even a sudden power cut does not leave damaged configurations or file systems. ### Can I use my own speakers? Yes. Every Audio Deck has a built-in 25 W amplifier for passive speakers of your choice, from ceiling speakers to floor-standing speakers. You are not tied to any particular speaker system. ### Which music sources are supported? Common streaming services², local music collections such as on a NAS, web radio and Bluetooth devices. We clarify which sources make sense for you in a consultation. ### How does installation work? We discuss rooms and requirements in advance and deliver the devices preconfigured. If you wish, we handle installation and commissioning on site, including cabling and a handover briefing. ### What does the Audio Deck cost? Every installation is different: number of rooms, existing cabling, speakers and server. You receive an individual quote, billed by time and materials or as a monthly maintenance subscription.
