For integration into a computer network, a gigabit Ethernet port and a dual-band Wi-Fi adapter are provided. Audio files can be played not only from network servers and streaming services, but also from external drives – there are two USB-A version 3.0 ports for connecting them.

The streamer also supports wireless broadcasting from mobile gadgets via Bluetooth 4.0. To connect external sources of digital content, there are coaxial and optical inputs, as well as a USB-B port.
